Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wallets are bulky, outdated for digital age needs, vulnerable to electronic theft, and not environmentally friendly due to materials and manufacturing processes.
Innovation Solution
A thin card-sized wallet made from recycled high-density polyethylene fibers (Tyvek) with RFID shields, designed to be super-thin, comfortable, and durable, featuring a unique folding structure for minimal size and water resistance, and incorporating structural inserts for enhanced durability and protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If traditional wallets are designed to store excessive articles, then storage capacity is improved, but wallet size becomes bulky and uncomfortable
Solution Approach 1:
The patent removes unnecessary storage compartments for outdated items (receipts, photos, business cards) from traditional wallets, retaining only essential card slots and cash pocket, thereby reducing overall wallet volume while maintaining adequate storage capacity for necessary items
Solution Approach 2:
The wallet design integrates multiple functions into a compact structure: card storage slots, cash pocket, RFID blocking layer for security, and a streamlined body that serves as both protection and organization, eliminating the need for separate compartments for each item type
2Volume of moving object
If wallets are made thin and compact, then comfort and portability are improved, but structural durability may deteriorate
Solution Approach 1:
The wallet combines multiple materials with complementary properties: a durable outer shell material for structural integrity, an RFID blocking layer for electronic protection, and optimized stitching patterns, creating a composite structure that maintains strength despite reduced thickness
Solution Approach 2:
The patent employs a thin-film construction with reinforced edges and corners, using flexible yet durable materials that can bend without breaking while maintaining protective capabilities, achieving a balance between thinness and structural durability
3Ease of manufacture
If wallets use traditional materials and manufacturing processes, then production cost is reduced, but environmental friendliness deteriorates
Solution Approach 1:
The patent specifies precise material parameters including recycled content requirements (minimum 50% post-consumer recycled material), thickness specifications for the RFID blocking layer, and stitching density parameters, allowing manufacturers to meet environmental goals while maintaining production efficiency through standardized specifications
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The wallet effectively addresses bulkiness, electronic theft, and environmental concerns by being ultra-thin, comfortable, and eco-friendly, while providing secure storage for essential items and protecting against RFID theft.
Implementation Method 1
electronic theft of data from radiofrequency identification (RFID) enabled credit cards can occur directly from ones wallet... The first structural insert and second structural insert may each further include an RFID shield to protect RFID enabled cards in the wallet from electronic theft

AI summary
A thin card sized wallet is provided herein that is super-thin, comfortable to wear, and minimally sized to store and transport essential articles. The thin card sized wallet is formed from a single piece of folded material and includes an obverse face, a reverse face, a pouch, a first sleeve, second sleeve, third sleeve, and fourth sleeve. The pouch is situated between the obverse face and reverse face and is configured to receive articles therein. The first sleeve and second sleeve are situated between the obverse face and the reverse face to receive one or more cards therein. The third sleeve and fourth sleeve are situated on the obverse face to receive one or more cards therein. The wallet may further include radiofrequency identification (RFID) shields to protect RFID enabled cards from electronic theft.
