Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional wallets and key holders are designed to hold multiple items, then they can accommodate various contents, but they become bulky and uncomfortable
Solution Approach 1:
The patent implements nesting by placing the card holder assembly inside the key holder assembly, with the card holder positioned within the cavity formed by the key holder's resilient member. This nested configuration allows multiple functional components to occupy overlapping spatial volumes, achieving high versatility while maintaining a compact overall footprint that fits within a standard wallet size envelope.
Solution Approach 2:
The patent utilizes three-dimensional spatial arrangement by configuring the key holder with a resilient member that expands in one dimension to receive keys, while the card holder nested within occupies a different spatial plane. This dimensional stratification allows the wallet to accommodate multiple item types without increasing its two-dimensional footprint, resolving the contradiction between capacity and size.
2Volume of moving object
If wallets are made compact to reduce bulk, then they become smaller and more portable, but they lose the ability to securely hold various contents and accessories
Solution Approach 1:
The patent employs dynamic elements including a resilient member that can expand and contract to accommodate varying numbers of keys, and a rotatable member that transitions between locked and unlocked positions. These dynamic components allow the compact wallet structure to adapt its internal configuration to securely hold different content volumes and types, maintaining reliability despite the reduced overall size.
Solution Approach 2:
The patent divides the wallet into segmented functional zones: a key holder section with resilient retention, a card holder section with dedicated card slots, and a rotatable accessory section. This segmentation allows each component to provide secure holding for its specific content type while collectively fitting within a compact form factor, preventing the trade-off between size and security.
3Adaptability or versatility
If wallets include multiple functional components to increase versatility, then they can hold various tools and accessories, but they become more complex and difficult to operate
Solution Approach 1:
The patent implements multi-functionality through a rotatable member that serves multiple purposes: it acts as a locking mechanism for the key holder, provides a mounting surface for tools or accessories, and can be manipulated to access different compartments. This universal component performs several functions that would otherwise require separate mechanisms, reducing overall structural complexity while maintaining high versatility.
Solution Approach 2:
The patent merges the card holder and key holder into a single integrated assembly where the card holder is nested within the key holder structure. This consolidation combines two separate functional components into one unified unit, reducing the number of separate parts and simplifying the overall device complexity while preserving both card and key holding capabilities.
4Reliability
If wallets use secure retention mechanisms to firmly hold contents, then contents are securely held, but the wallet becomes bulkier and less comfortable
Solution Approach 1:
The patent uses a resilient member that functions as a flexible retention mechanism, utilizing elastic deformation to exert retaining force on keys and other contents. This flexible element provides secure holding capability while occupying minimal space, as the retention force is generated through material elasticity rather than through a bulky mechanical structure, thus maintaining a slim wallet profile.

AI summary
The present invention is a compact utility wallet design to hold card-like contents and keys and tool accessories. First and second rigid plates are interposed to sandwich card-like contents there between. At least one encircling elastic band is interposed with the at least two rigid plates along longitudinal extents thereof to bias them inwardly and securely hold the card-like contents while providing elastic volume there between for adding or removing contents. At least three bosses are peripherally arranged toward sides of the first rigid plate on a surface facing opposite of the second rigid plate and configured to rotatable mount keys or tools. A third rigid plate is removably attached to the first rigid plate by threaded fasteners, one threaded fastener received by each boss. A first cover plate is removably attached to the third rigid plate and a second cover plate is removably attached the second rigid plate.
