Wallet Shaping Element Rectangular Profile
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wallets are not adequately designed to accommodate the increasing use of plastic cards and less paper currency, posing challenges in security and comfort, especially when carried in a front pocket in areas prone to pickpocketing.
Innovation Solution
A wallet with a rectangular sleeve and shaping element, optionally featuring a strap and radio-frequency blocking materials, designed to securely hold multiple cards and currency, with a design that minimizes the risk of unauthorized access and discomfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional wallet is designed to hold both paper currency and plastic cards, then it can accommodate traditional payment methods, but it becomes bulky and unsuitable for front pocket carrying in areas prone to pickpocketing
Solution Approach 1:
The wallet is divided into separate functional zones: a first pocket for paper currency and a second pocket for plastic cards. This segmentation allows each pocket to be optimized for its specific function, reducing overall wallet bulk while maintaining versatility for both payment methods
Solution Approach 2:
The wallet design transitions from a single large compartment to a flattened profile with multiple thin layers/pockets. By organizing contents in a two-dimensional layered structure rather than a single three-dimensional space, the wallet achieves compactness suitable for front pocket carrying while still accommodating both currency and cards
2Quantity of substance
If a large wallet is carried in a hip pocket, then it can hold all necessary items, but it may have adverse effects on the back
Solution Approach 1:
By segmenting the wallet into multiple thin pockets rather than one large compartment, the overall thickness and bulk are reduced. This allows the wallet to hold necessary items while maintaining a slim profile that can be comfortably carried in a front pocket, eliminating the harmful effect of heavy hip pocket carrying
Solution Approach 2:
Instead of carrying a large bulky wallet in the hip pocket, the design inverts the approach by creating a compact front-pocket-friendly wallet with optimized internal organization. This reverses the traditional wallet-carrying paradigm to eliminate back strain while maintaining capacity
3Object-affected harmful factors
If the wallet is designed with a compact profile for front pocket carrying, then it improves security against pickpocketing, but it reduces the capacity to hold multiple cards and currency
Solution Approach 1:
The compact wallet is segmented into multiple specialized pockets: a first pocket for currency and a second pocket for cards. This segmentation maximizes the use of available space within the compact form factor, allowing the wallet to hold multiple cards and currency while maintaining a secure front-pocket-friendly profile
Solution Approach 2:
The wallet utilizes flexible thin-walled construction with multiple layers to create compact pockets. This allows the wallet to maintain a slim compact profile suitable for front pocket carrying while providing sufficient capacity through efficient use of flexible space to hold multiple cards and currency
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 secures and protects a variety of cards and currency, reducing the risk of theft and discomfort by accommodating modern payment methods and materials that interfere with RFID signals, enhancing user security and comfort.
Implementation Method 1
The wallet comprises a sleeve that is flattened into a rectangular profile... and a shaping element that is secured to an interior surface of the sleeve for retaining the sleeve in the rectangular profile
Implementation Method 2
the wallet also comprises a means for interfering with transmission of radio frequency signals through the sleeve, incorporated in at least one of the sleeve and the shaping element

AI summary
A wallet (110) for holding a plurality of rectangular cards (C) has a sleeve (112) that is flattened into a rectangular profile. The sleeve is maintained in the rectangular profile by a shaping element (130) that is secured to an interior surface of the sleeve. The rectangular profile has a length and a width that are substantially the same as that of the cards intended on be held, the length being the larger of the dimensions. The sleeve is open along the width edges (20, 22) and closed along the length edges. Optionally, a strap (140) that passes across an exterior surface of the sleeve from one of the width edges to the other width edge, with its ends secured inside the sleeve, is useful for retaining folded paper currency and the like. The strap ends are secured to at least the shaping element.
