FIELD OF THE INVENTION

The present invention relates generally to personal accessories and storage devices, and more particularly to modular wallet systems for organizing and carrying identification cards, credit cards, and similar card-shaped items. Specifically, the invention pertains to expandable card storage systems that utilize magnetic attachment mechanisms and stackable plate configurations to provide customizable capacity and selective access to stored cards and other items.

BACKGROUND OF THE INVENTION

In recent years, the evolution of personal finance and identification systems has led to an increased reliance on various cards for daily transactions and access control. Individuals often find themselves carrying multiple credit cards, identification cards, and key badges for different purposes. This proliferation of cards has created several challenges for users in terms of organization, accessibility, and convenience.

Traditional wallets, while serving their primary purpose of carrying cards and cash, have not adequately addressed the growing complexity of card management. Users frequently encounter difficulties when trying to locate a specific card within a bulky wallet, especially in time-sensitive situations such as making a purchase or accessing a secure area.

Moreover, the need to display identification or key badges without removing them from a wallet has become increasingly important in various professional and security contexts. Current wallet designs often require users to completely remove cards from their protective casing, increasing the risk of loss or damage.

Another significant issue faced by consumers is the limited expandability of conventional wallets. As the number of cards an individual needs to carry increases, wallets often become overstuffed, leading to wear and tear on both the wallet itself and the cards contained within. This lack of flexibility in wallet capacity forces users to either carry multiple wallets or periodically sort through and remove cards, which can be inconvenient and potentially result in important cards being left behind.

The durability and longevity of wallets have also been ongoing concerns for consumers. Traditional materials used in wallet construction may not withstand the rigors of daily use, leading to frequent replacements and additional expenses. This issue is compounded by the fact that wallets are often subjected to various environmental conditions, from the heat of a car interior to the moisture of a pocket.

Furthermore, the ability to quickly and easily access only the necessary cards for a given situation, without exposing or potentially losing other cards, remains a challenge with current wallet designs. Users often find themselves fumbling through multiple cards to find the one they need, which can be both time-consuming and frustrating.

In light of these challenges, there is a clear need for innovative solutions in personal card management that address the issues of expandability, accessibility, durability, and selective card presentation. Such solutions would not only enhance user convenience but also potentially improve security and organization in an increasingly card-dependent world.

SUMMARY OF THE INVENTION

The present invention relates to an innovative modular wallet system designed to address the challenges of modern card management. This system comprises a series of stackable plates, each configured to hold various types of cards, including identification cards and credit cards.

The core component of the invention in various embodiments is the plate, which comes in two primary configurations: an ID holder plate and a credit card holder plate. The ID holder plate is designed to accommodate two identification cards, one on each side, while the credit card holder plate can store up to three credit cards on a single side.

A key feature of the invention is its expandability. Users can stack multiple plates together, with a practical capacity of up to five plates in a single stack, resulting in a total thickness of less than one inch. This configuration allows for a maximum capacity of 14 cards when fully expanded.

The plates are held together using a unique magnetic attachment system. Each plate incorporates magnets in its corners, with opposite polarities ensuring proper alignment and secure connection between plates. This design allows for easy assembly and disassembly of the wallet, providing users with the flexibility to adjust their wallet's capacity as needed.

The magnetic attachment system of the modular wallet comprises one magnet per corner of each plate. These magnets are oriented with specific polarity to ensure proper alignment and secure connection between adjacent plates when stacked. The polarity of each magnet is arranged such that it aligns with opposite polarity magnets in the corners of adjacent plates. This configuration allows the plates to be flipped in any direction while maintaining correct orientation and secure attachment. The magnetic system works in conjunction with the tab and recess alignment mechanism to prevent lateral movement between stacked plates. This design ensures that the plates stay securely connected during use, reducing the risk of accidental separation and potential loss of cards. The magnetic attachment system, combined with the tab and recess feature, provides a robust and user-friendly method for assembling and disassembling the modular wallet, allowing users to easily customize their wallet configuration based on their specific card-carrying needs.

To enhance stability and prevent unwanted movement between plates, the invention in various embodiments incorporates a tab and recess system. Each plate features four tabs that correspond to four recesses in the adjacent plate, ensuring precise alignment and minimizing lateral movement when the plates are stacked.

The plates are designed with dimensions similar to standard credit cards and IDs, ensuring compatibility with a wide range of card types. The current design features an octagonal shape, with potential for rounded corners to reduce wear and tear on clothing.

Card retention protrusions are incorporated into each plate, extending over the recessed area where cards are placed. These protrusions prevent cards from falling out when the wallet is oriented downward, ensuring secure storage. The invention in various embodiments offers multiple material options, including aluminum, titanium, and plastic, each with its own advantages in terms of durability, weight, and cost.

This modular wallet system addresses several key issues in personal card management, including expandability, accessibility, durability, and selective card presentation. It provides users with a customizable solution that can adapt to their changing needs while maintaining a slim profile and enhancing convenience in daily use.

The modular wallet system in various embodiments offers enhanced security through its magnetic attachment system and tab-recess alignment mechanism. Each plate incorporates one magnet per corner, with two magnets stacking against each other in each corner. The polarity of these magnets is arranged such that opposites are in the corners, allowing the plates to be flipped in any direction and oriented correctly. This design ensures a secure connection between plates, reducing the risk of accidental separation.

Various embodiments of the invention provided for enhanced organizational efficiency, as the system comprises two distinct plate types: the ID holder plate and the credit card holder plate. The ID holder plate is designed to accommodate two identification cards, one on each side, with a shallower recess depth of approximately ⅓ the depth of a credit card holder plate. This design allows for quick access and display of identification cards without removing them from the wallet entirely.

The credit card holder plate, on the other hand, is configured to hold up to three credit cards on one side, with a deeper recessed area of 0.125 inches. This separation of card types enables users to organize their cards more effectively, grouping similar cards together (e.g., credit cards, loyalty cards, or access cards).

An example of this organizational efficiency in use could be a professional who needs to carry multiple access cards for different office locations, along with personal credit cards and identification. By using separate plates for each category, they can quickly access the required cards without shuffling through unrelated items.

The modular nature of the system allows for shared wallet configurations, catering to various personal and professional needs. Users can combine plates to create custom wallet setups that suit their specific requirements. For instance, a couple could create a shared wallet by combining their individual plates, allowing them to carry both sets of cards in a single, organized unit.

Another example of a shared configuration could be in a corporate setting where employees need to carry multiple key badges for different access levels or locations. The modular system would allow the company to issue standardized plate sets to employees, which can be easily customized based on individual access requirements. This flexibility not only improves organization but also enhances security by allowing employees to carry only the necessary access cards for their specific roles.

In a family context, parents could create a modular wallet that includes plates for family identification cards, medical insurance cards, and emergency contact information, which can be easily shared among family members as needed for various activities or appointments. These shared configurations demonstrate the versatility of the modular wallet system in adapting to diverse user needs while maintaining organizational efficiency and security across various personal and professional scenarios.

The core component of a preferred embodiment of the invention is the plate, which serves as the basic building block of the wallet system. These plates come in two primary configurations: an ID holder plate and a credit card holder plate. In an embodiment of the invention, the ID holder plate is designed to accommodate two identification cards, one on each side, while the credit card holder plate can store up to three credit cards on a single side.

One of the key features of a preferred embodiment of the invention is its expandability. Users can stack multiple plates together, with a practical capacity of up to five plates in a single stack, resulting in a total thickness of less than one inch. This configuration allows for a maximum capacity of 14 cards when fully expanded in accordance with a preferred embodiment comprising five plates, which the present inventor has noted is a configuration that maximizes the reasonable capacity of cards without the need for excess bulk. It should be noted that in various embodiments of the invention, there is no limitation to the number of plates that can be staked together allowing for infinite expandability of the wallet.

In an embodiment of the invention, the plates are held together using a uniquely configured magnetic attachment system. Each plate incorporates magnets in its corners, with opposite polarities ensuring proper alignment and secure connection between plates. This design allows for easy assembly and disassembly of the wallet, providing users with the flexibility to adjust their wallet's capacity as needed.

To further enhance stability and prevent unwanted movement between plates, a preferred embodiment of the invention incorporates a tab and female tab receptacles system. Each plate features four tabs that correspond to four female tab receptacles in the adjacent plate, ensuring precise alignment and minimizing lateral movement when the plates are stacked. To enhance stability and prevent sliding between stacked plates, each plate features a tab and female tab receptacle system. Four tabs on each plate correspond to four female tab receptacles in the adjacent plate. The tabs are oriented consistently, with the tab positioned to the left of the magnet on the top border and to the right of the magnet on the bottom border. This configuration facilitates interoperability between plates and ensures proper magnetic attraction. The tabs in accordance with various embodiments are oriented consistently among plates in standardized locations to facilitate interoperability with other plates in the system. On the top border of the plate, the tab is to the left of the magnet, while on the bottom border, the tab is to the right of the magnet. This orientation allows the magnets to attract between plates given the intended polarity during use.

The tab and female tab receptacle system further enhances security and stability. Each plate features four tabs that correspond to four female tab receptacles in the adjacent plate. These tabs are oriented consistently, with the tab positioned to the left of the magnet on the top border and to the right of the magnet on the bottom border. This configuration prevents lateral movement between stacked plates, ensuring that cards remain securely in place even when the wallet is jostled or inverted. An exemplary use case for this security feature would be in high-activity environments, such as amusement parks or sporting events, where traditional wallets might risk falling open or losing cards. The secure magnetic and tab system allows users to carry their cards with confidence in such situations.

In an embodiment of the invention, the plates are designed with dimensions comprising a card recess into the plate slightly larger than the dimensions of standard credit cards and IDs, ensuring compatibility with a wide range of card types. Each plate further comprises a raised border on one or both sides. In an embodiment, the raised border of each plate extends 0.175 inches inward from the external edge to the internal edge of the card recess where the card is placed, and the card recess for the three-card holder is 0.125 inches deep.

In an embodiment of the invention, the wallet system comprises two primary plate configurations: the ID holder plate and the credit card holder plate. The ID holder plate is designed to accommodate two identification cards, one on each side, with the distance from the floor of the plate to the inferior aspect of the tab at least partially surrounded by the raised border, the space within which comprises the card recess, being approximately ⅓ the height of the credit card holder. The credit card holder plate is configured to retain up to 3 credit cards on one side, with its backside designed to serve as the exterior aspect of the wallet in its combined form, without any card facing outward.

The ID holder plate in an embodiment of the invention is designed with a double-sided configuration, allowing each side of the plate to hold one ID or alternatively one card. This design maximizes the utility of the plate by providing space for two identification cards or similar items. The recessed area for card placement is shallower compared to the credit card holder plate, with the distance from the floor of the plate to the inferior aspect of the tab being approximately ⅓ the height of the credit card holder. This shallower design allows for easier access and visibility of the ID, which is particularly advantageous in situations where quick display of identification is necessary, such as at security checkpoints or when entering secured areas.

The credit card holder plate, in contrast, is configured with a single-sided design, capable of retaining up to 3 credit cards on one side. The recessed area for card placement is deeper, measuring approximately 0.125 inches. This deeper recess allows for secure storage of multiple cards while maintaining a slim profile. The backside of the credit card plate is designed to be flat, allowing it to serve as a smooth exterior aspect of the wallet in its combined form, which facilitates additional durability and enables easier sliding within and out from clothing. This configuration provides a smooth outer surface when the wallet is assembled, preventing any cards from facing outward and potentially snagging on clothing or other items.

Both plate types incorporate card retention protrusions that are flush with the border and extend over the recessed area. These protrusions overlap the internal diameter of the border by approximately 0.05 inches, providing just enough coverage to prevent cards from falling out when the wallet is oriented downward. The distance from the floor of the recess to the inferior aspect of these card retention protrusions is about 0.105 inches, ensuring a secure fit for the cards while still allowing easy insertion and removal. In an embodiment, the modular wallet system incorporates card retention protrusions designed to securely hold cards within the recessed area of each plate. These protrusions are flush with the raised border of the plate, ensuring a seamless profile while providing effective card retention. For an exemplary embodiment of the ID holder plate, the card retention protrusions extend approximately 0.05 inches over the recessed area, while for an exemplary embodiment of the credit card holder plate, they extend approximately 0.02 inches. This design allows for secure card placement while still enabling easy insertion and removal of cards. Thus, in accordance with various embodiments, the protrusions extend approximately 0.01-0.08 inches in various configurations. The protrusions overlap the internal diameter of the border just enough to prevent cards from falling out when the wallet is oriented downward, without impeding the functionality of the tab and recess system or the magnetic attachment mechanism. The distance from the floor of the recessed area to the inferior aspect of these card retention protrusions is approximately 0.105 inches, ensuring a secure fit for cards of standard thickness.

The ID holder plate offers several advantages and intended uses. It allows for quick and easy display of identification without the need to remove the card from the wallet entirely. This feature is particularly useful for individuals who frequently need to show ID, such as employees accessing secure areas or travelers passing through security checkpoints, simply by separating that portion of the wallet system and then reattaching that portion back to the wallet quickly and conveniently when complete. The ability to store two IDs, one on each side, also provides flexibility for users who may need to carry multiple forms of identification.

The credit card holder plate is advantageous for users who carry multiple credit cards, debit cards, or other similarly sized cards. Its capacity to hold up to three cards in a single plate allows for efficient organization and storage of payment methods and other frequently used cards. The flat backside design contributes to the overall sleek profile of the assembled wallet and provides protection for the cards when the wallet is placed in a pocket or bag.

In an embodiment of the invention, each of the plates are designed with specific dimensions to accommodate standard credit cards and identification cards. The border of each plate is approximately 0.175 inches inward from the external edge to the internal edge of the recess where the card is placed. For the credit card holder plate, the recess is approximately 0.125 inches deep, allowing for secure placement of up to three credit cards. In various configurations, each of the stackable plates is configured to hold at least one card, or at least one auxiliary item such as a solid-state drive (SSD) (210), paper currency (202), a battery (220), or another similarly shaped item appropriate to carry within a wallet-like enclosure. The modular design accommodates these auxiliary electronic components securely within the recessed areas of the plates, with the same retention mechanisms that secure traditional cards. The SSD (210) and battery (220) storage capabilities extend the wallet's functionality beyond conventional card management, allowing users to carry essential electronic components in a compact, organized manner. The modular wallet system in an embodiment is specifically designed to accommodate paper currency (202) alongside traditional cards and auxiliary items. The recessed areas of both ID holder plates and credit card holder plates can securely hold folded paper money, with the card retention protrusions providing adequate clearance for currency of varying thicknesses. This money storage capability (202) allows users to maintain a truly comprehensive wallet solution that addresses both card management and cash carrying needs within the same modular framework.

The ID holder plate in an embodiment is configured differently, with the distance from the floor of the plate to the inferior aspect of the tab being roughly ⅓ the height of the credit card holder. This design allows for easy access to and display of identification cards (203). The shallow recess design facilitates quick presentation of identification (203) without removal from the wallet, while also accommodating auxiliary items such as SSD cards (210), paper currency (202), or other similarly dimensioned items when needed.

Card retention protrusions are incorporated into each plate in accordance with various configurations, extending over the recessed area where cards are placed. These protrusions are flush with the contact surface of the border and overlap the internal diameter of the border by approximately 0.05 inches. The distance from the floor of the recess to the inferior aspect of the card retention protrusions is about 0.105 inches. This design prevents cards from falling out when the wallet is oriented downward. Thus, in an embodiment of the invention, each plate comprises card retention protrusions that are flush with the border and extend over the recessed area where cards are placed. These protrusions overlap the internal diameter of the border by approximately 0.05 inches, just enough to prevent a card from falling out if oriented downward. The distance from the floor of the card recess to the inferior aspect of the card retention protrusions is approximately 0.105 inches in an embodiment.

Both plate types contribute to the overall modularity and expandability of the wallet system, allowing users to customize their wallet configuration based on their specific needs. This flexibility addresses the problem of limited expandability in conventional wallets and provides a solution for users who need to carry varying numbers of cards depending on their daily activities or changing requirements.

A feature of an embodiment of the invention is the magnetic attachment system. Each plate incorporates one magnet per corner, with two magnets stacking against each other in each corner. The polarity of these magnets is arranged such that opposites are in the corners, allowing the plates to be flipped in any direction and oriented correctly. Each plate incorporates a magnetic attachment system, with one magnet per corner. In the current configuration, two magnets stack against each other in each corner. The polarity of these magnets is arranged to ensure proper alignment and connection between plates. This is how the design allows users to flip the plates in any direction while maintaining correct orientation.

A significant feature of an embodiment of the invention is its expandability. The wallet can comprise as few as one ID plate or as many stacked plates as the user desires. Practically, a comfortable configuration for pocket use might include 5 or 6 plates, while users who carry the wallet in a purse might prefer additional plates. In a configuration with 5 stacked plates, the total thickness is less than 1 inch, and the wallet can hold up to 14 cards (2 in the ID holder and 3 in each of the four credit card holders). This modular design allows for multiple user configurations, such as combining wallets for couples or for shared key badges in various applications.

Regarding material options, the invention considers several possibilities, each with its own advantages and disadvantages. An aluminum body offers durability superior to most plastics while remaining lightweight. It also has the potential for a shiny appearance, which may be desirable for some users. However, aluminum is more expensive than plastic. An aluminum body offers advantages of being tougher than most plastics while remaining light, with the potential for a shiny appearance but at a higher cost than plastic. A titanium body provides superior strength compared to plastics and aluminum while maintaining lightness, though it is very expensive. Plastic is suitable for initial prototyping and production due to its ability to be 3D printed and very low cost, although certain plastics like PLA may melt in high temperatures, while ABS is more durable but harder to print. Additional materials required for assembly include magnets and epoxy or superglue to retain the magnets. Each plate is designed as a single piece, excluding the magnet and adhesive. A titanium body provides even greater strength compared to aluminum and plastics, while still maintaining a light weight. The main disadvantage of titanium is its high cost, making it the most expensive option. Plastic is the chosen material in an embodiment due to its low cost and ability to be 3D printed. However, certain plastics like PLA may melt in high temperatures, such as when left in a car. The present inventor has recognized that ABS plastic offers better durability and heat resistance but is more challenging to 3D print. The modular wallet system can be constructed using various materials, each offering unique advantages for different user preferences and needs. Aluminum provides a lightweight yet durable option, offering superior strength compared to most plastics while maintaining a sleek appearance. Titanium, while more expensive, offers even greater strength-to-weight ratio, making it an ideal choice for users seeking maximum durability. Stainless steel provides excellent corrosion resistance and strength, suitable for long-term use in various environments. Damascus steel, known for its distinctive patterns and high strength, offers a premium aesthetic option. Inconel, a superalloy known for its exceptional strength and corrosion resistance, provides a high-end material choice for users in demanding environments. Plastic, particularly high-quality thermoplastics like ABS, offers a cost-effective and lightweight option suitable for initial prototyping and production. Each material choice allows for customization of the wallet system to meet specific user requirements, such as durability, weight, aesthetics, or cost considerations.

Accordingly, the modular wallet system in various embodiments is constructed using various materials, optionally aluminum, titanium, and stainless steel as described above, each offering unique advantages for different user preferences and needs. In an alternative embodiment, the modular wallet system is constructed from Damascus steel, known for its distinctive patterns and high strength, which offers a premium aesthetic option; or Inconel, a superalloy known for its exceptional strength and corrosion resistance, which provides a high-end material choice for users in demanding environments. The selection of these materials ensures that the modular wallet system can be tailored to a wide range of user preferences while maintaining its core functionality and design features.

The modular design of the invention allows for significant flexibility in terms of capacity. Users can stack as few as one plate or as many as desired, with a practical limit of 5 or 6 plates for comfortable pocket use. A configuration with 5 stacked plates results in a total thickness of less than 1 inch and can hold up to 14 cards (2 in the ID holder and 3 in each of the four credit card holders). This expandability feature addresses the need for accommodating varying numbers of cards and allows for shared wallet configurations, such as for couples or for organizing multiple key badges. In various configurations, each of the stackable plates is configured to hold at least one card, or at least one auxiliary item such as a SSD card, a bill of currency, or another similarly shaped item appropriate to carry within a wallet-like enclosure. The system's versatility is further demonstrated through its ability to securely store credit cards (201), identification cards (203), paper money (202), solid-state drives (210), and batteries (220), as shown in the assembled configuration. This comprehensive storage capability addresses the modern user's need to carry both traditional wallet contents and contemporary electronic accessories in a single, organized system.
