Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional wallets require reopening to view contents, leading to potential loss of items like credit cards, and money clips lack security as spring tension wears, causing items to fall out.

Innovation Solution

A dual lock wallet design featuring two sheets of pliable material with locking fixtures, such as sockets and snaps, hooks and loops, or clasp systems, allowing contents to be viewed and secured, with cutouts for visibility and a finger slot for easy removal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a conventional billfold wallet is closed to secure contents, then security is improved, but the ability to view contents without opening is lost

Engineering Contradiction:

Improvesecurity of contentsVSAvoidability to view contents

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The wallet is divided into multiple panels (first panel, second panel, third panel) with distinct functions. The first and second panels form the main body while the third panel acts as a secure closure flap with locking mechanism. This segmentation allows different regions to serve different purposes: storage, security, and visibility.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A transparent window is introduced as an intermediary element between the user and the wallet contents. This window allows optical transmission so users can view contents through the closed wallet without physically opening it, thereby maintaining security while enabling content verification.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If a money clip is used to hold cash and cards, then visibility of contents is improved, but security deteriorates as spring tension wears

Engineering Contradiction:

Improvevisibility of contentsVSAvoidsecurity of contents

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The traditional spring-based clamping mechanism is replaced with a panel-based folding and locking system. Instead of relying on spring tension that degrades over time, the wallet uses the flexibility of the third panel that can be folded over and secured with locking fixtures, providing reliable security without mechanical wear.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If a folded billfold wallet is made secure, then reliability is improved, but the wallet becomes thick and bulky

Engineering Contradiction:

Improvesecurity of closureVSAvoidthickness of wallet

Core Design Contradiction:

ReliabilityVSVolume of moving object

Solution Approach 1:

The wallet utilizes the third dimension by folding the third panel over the contents and securing it with locking fixtures. This vertical folding approach maintains a slim profile while providing secure closure, avoiding the need for thick multiple folds.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)
