Stealth Micro-Ballistic Billfold Offset Card Slots
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wallets, especially bi-fold designs, cause discomfort and pressure on the Sciatic nerve, leading to lower back pain and the risk of wallet loss when removed for extended periods, due to their thickness and bulkiness.
Innovation Solution
A slim, micro-ballistic billfold design that eliminates the need for an internal skeleton, using offset card slots and a micro-ballistic bill loop for card and currency storage, allowing the cards to act as structural support and reducing the wallet's thickness while maintaining strength and functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional bi-fold wallet design is used, then it can hold cards and currency, but it causes pressure on the Sciatic nerve leading to lower back pain
Solution Approach 1:
The patent changes the thickness parameter of the wallet from traditional thick bi-fold design to an ultra-thin configuration. The wallet measures significantly thinner than conventional wallets while maintaining card and currency capacity, thereby eliminating Sciatic nerve pressure during sitting without compromising functionality.
Solution Approach 2:
The patent extracts and removes the internal skeleton structure traditionally used in wallets for structural support. By eliminating this internal framework, the wallet achieves ultra-thin dimensions while cards themselves provide the necessary structural support, resolving the contradiction between thickness and structural integrity.
2Reliability
If a thick wallet is used, then it provides structural support, but it increases the risk of loss when removed for extended periods
Solution Approach 1:
The patent changes the thickness parameter to ultra-thin dimensions, making the wallet comfortable enough to wear continuously in the back pocket without removal. This eliminates the risk of loss associated with taking the wallet out and putting it down, while the thin profile is maintained through the absence of internal skeleton structure.
Solution Approach 2:
The patent implements a self-service structural support system where cards stored in the wallet provide the structural support traditionally provided by an internal skeleton. This eliminates the need for thick internal frameworks while maintaining wallet integrity, allowing continuous wear for security.
3Stability of the object's composition
If an internal skeleton structure is added, then the wallet maintains its shape, but the thickness and bulkiness increase
Solution Approach 1:
The patent extracts and removes the internal skeleton structure from the wallet design. By taking out this traditional structural element, the wallet achieves ultra-thin dimensions while maintaining shape stability through alternative means - specifically, the cards stored in the wallet provide the necessary structural support.
Solution Approach 2:
The patent implements a self-service structural support system where the wallet's contents (cards) provide the structural support traditionally provided by an internal skeleton. This eliminates the need for thick internal frameworks while maintaining wallet integrity and shape stability.
4Length of stationary object
If a micro-ballistic bill loop design is used, then the wallet becomes thinner and more cut-proof, but the manufacturing complexity increases
Solution Approach 1:
The patent changes the thickness parameter to ultra-thin dimensions while enhancing cut-proof capabilities through the micro-ballistic bill loop design. The bill loop is constructed with vertically stacked, overlapping loops that provide superior cut resistance in a thin profile, achieving both thinness and enhanced protection.
Solution Approach 2:
The patent employs composite construction in the bill loop using vertically stacked, overlapping loops of material. This layered composite structure provides enhanced cut-proof capabilities while maintaining an ultra-thin overall thickness, balancing manufacturing complexity with performance benefits.

AI summary
A wallet is designed to be folded in half along a central bill loop that can hold paper currency thereunder. The opened wallet, on each side of the bill loop, can include a card slot formed therein. When opened, the wallet can have four corners that, when folded, meet to form two outside corners of the folded wallet while two inside corners are formed at ends of the folded portion. The left-side card slot can be offset from the right-side card slot such that, when folded, cards in the left-side card slot can provide support adjacent one outside corner of the wallet, while cards in the right-side card slot can provide support adjacent the other outside corner of the wallet. Thus, the wallet is structurally supportive without requiring any additional elements to provide such support, outside of the user's own cards stored in the wallet.
