Loop Wallet with Bendable Metal Strips for Compact Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wallets fail to balance ease of carrying, secure storage, and comfort while accommodating currency, credit cards, and business cards, often being either bulky or lacking in accessibility and durability.
Innovation Solution
A wallet design featuring a closed flat loop of non-stretchable material with integrated bendable metal strips and an optional magnetized closing mechanism, along with a rotatable credit card loop and an optional finger loop, to securely hold and easily access various types of cards and currency, reducing bulk and enhancing durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a large leather wallet is used to hold currency, credit cards, and business cards, then the storage capacity and functionality are improved, but the size and bulk increase making it uncomfortable to carry in a pocket
Solution Approach 1:
The wallet is divided into multiple functional loops: a first loop for currency, a second loop for additional currency or cards, and a third loop for business cards. Each loop is independent and can be opened or closed separately, allowing selective access to different types of contents while maintaining a compact overall structure that fits in a pocket.
Solution Approach 2:
The patent transitions from a traditional flat wallet layout to a three-dimensional loop structure that extends in multiple directions from a central point. This spatial arrangement allows contents to be organized in different planes and levels, maximizing storage capacity within a small volume that comfortably fits in a pocket.
2Volume of moving object
If a money clip is used to hold currency, then the size and portability are improved, but the functionality to hold credit cards and business cards is lost
Solution Approach 1:
The wallet structure serves multiple functions through its loop design: the first loop functions as a money clip for currency, while the second and third loops provide additional storage for cards and business cards. The same basic loop structure adapts to hold different types of items, making the compact device universally applicable for various carrying needs without increasing bulk.
3Reliability
If traditional wallet designs are used to securely hold contents, then the security is improved, but the ease of access to contents and handling efficiency deteriorate
Solution Approach 1:
The wallet employs dynamic loop structures that can be easily opened and closed by simple finger movements. Each loop can be independently manipulated to access its contents without requiring the entire wallet to be opened, providing both security when closed and rapid access when needed. The loops can be quickly snaped open and closed, enabling efficient handling during transactions.
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 design allows for comfortable pocket carry, secure storage, and easy access to contents, with enhanced durability and flexibility, accommodating varying amounts and thicknesses of currency and cards, while minimizing bulk and improving handling efficiency.
Implementation Method 1
a flat length of bendable metal within the first lumen in the first length which allows the closed flat loop to retain a desired shape
Implementation Method 2
a magnetized adjustable closing mechanism where a magnet secures an end of the vertical strip to a metal containing portion of the vertical strip
Data Source
AI summary
An article for holding currency and credit cards is disclosed which comprises (a) a first length of substantially non-stretchable material having a first end and a second end configured to form a closed flat loop when the first end is retained on or near the second end, a lumen in the first length, a flat length of bendable metal within the lumen in the first length which allows the closed flat loop to retain a desired shape, the closed flat loop having a length which is slightly longer than half the length of U.S. currency; (b) a second length of substantially non-stretchable material having a middle, a first end, a second end, and a lumen, the first end and the second end secured to the first length of substantially non-stretchable material, thereby forming a second flat loop slightly wider than the width of U.S. currency, the middle secured to a point on the first length (a) to maintain the first flat loop perpendicular to the second flat loop, the lumen in the second length containing a flat strip of bendable metal.
