Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wallets are often inflexible, limited in capacity, and prone to moisture damage, necessitating frequent replacement, while lacking the ability to be easily customized or expanded.
Innovation Solution
An adjustable interlocking wallet featuring a flexible loop of stretchable material with interlocking clasps and attachable clips, allowing for expansion, compactness, and easy replacement of the body, utilizing elastic elements and various materials like braided or knitted fabric and leather.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional wallets are made from fabric or leather, then they provide basic containment functionality, but they are sensitive to moisture, wear out, and require frequent replacement
Solution Approach 1:
The patent changes the material parameter from traditional fabric or leather to plastic, which fundamentally alters the material's resistance to moisture and wear. This parameter change enables the wallet to withstand harsher environments without degrading, directly resolving the contradiction between durability and moisture sensitivity
Solution Approach 2:
The wallet construction uses multiple plastic components (body, clasps, clips) that can be considered a composite structure. This allows each component to be optimized for its specific function while maintaining overall durability and moisture resistance, addressing the reliability issue through material composition
2Adaptability or versatility
If wallets are made with fixed structure, then they are simple to manufacture, but they are inflexible and limited in the number of articles that can be accommodated
Solution Approach 1:
The wallet is divided into separable components including the body, clasps, and clips that can be independently manufactured and assembled. This segmentation allows the wallet to expand in capacity by adding or removing clips while keeping the manufacturing of each individual component relatively simple, resolving the contradiction between adaptability and manufacturing complexity
Solution Approach 2:
The wallet incorporates dynamic elements such as attachable and detachable clips that can be added or removed based on user needs. This dynamic configuration allows the wallet to adapt its capacity and functionality without requiring a completely different structure, balancing versatility with manageable complexity
3Quantity of substance
If wallets are made compact and slim, then they are portable and convenient, but they are limited in capacity for holding multiple items
Solution Approach 1:
The wallet design nests multiple functional elements within a compact form - clips are attached to the body, cards are held within the body structure, and clasps secure the entire assembly. This nested arrangement maximizes capacity within a slim profile by efficiently utilizing internal space rather than expanding external dimensions

AI summary
An adjustable interlocking wallet includes a body comprising a flexible loop of stretchable material and at least two clasps which interlock with one another to secure the wallet in a closed position. The wallet also includes clips that are attachable to the loop, slide thereon and retain the at least two clasps on the body.
