Self-Arranging Wallet with Inclined Sidewalls and RFID Shielding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wallets lack self-arrangement, theft-proofing, and water-resistance, leading to increased volume, inconvenience, and vulnerability to RFID card hacking due to soft materials that cannot resist improper wireless identifiers.
Innovation Solution
A receiving folder with self-arrangement, featuring a top cover and bottom case with inclined sidewalls, clamping units, an elastic unit, and an electromagnetic layer, allowing for sequential card arrangement and protection against RFID hacking, while maintaining a lightweight and water-resistant design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple folders are used to store different cards, then card storage capacity is improved, but wallet volume increases
Solution Approach 1:
The wallet is divided into multiple functional zones within a single folder structure: card storage slots, bill compartment, coin pocket, and receipt section. This segmentation allows organized storage of different items types without requiring multiple separate folders, thereby maintaining compact volume while improving storage capacity.
Solution Approach 2:
The single folder structure is designed to perform multiple functions simultaneously: storing cards in designated slots, holding bills in a separate compartment, containing coins in a mesh pocket, and accommodating receipts. This multi-functionality eliminates the need for multiple specialized folders, reducing overall wallet volume while maintaining comprehensive storage capacity.
2Ease of operation
If soft materials are used for wallet construction, then comfort and flexibility are improved, but RFID card security deteriorates
Solution Approach 1:
The wallet employs a composite material structure combining soft outer material for comfort with an embedded electromagnetic shielding layer (such as metal mesh or conductive fabric) that blocks RFID signals. This composite construction maintains the flexibility and user comfort of soft materials while adding theft-proof protection against unauthorized RFID scanning and hacking.
Solution Approach 2:
An electromagnetic shielding layer acts as an intermediary between the RFID cards and external radio waves. This intermediate layer blocks harmful electromagnetic signals from reaching the cards, preventing hacking while allowing the wallet to maintain its soft, comfortable construction for ease of operation.
3Ease of manufacture
If conventional wallet structures are used, then manufacturing simplicity is maintained, but self-arrangement and quick access functionality are lost
Solution Approach 1:
Cards are pre-arranged in designated slots and positions within the folder during manufacturing, creating a self-arranging structure. When the wallet is opened, cards are automatically positioned in an organized sequence, enabling quick visual identification and access without requiring the user to manually sort through disorganized cards. This preliminary arrangement maintains manufacturing simplicity while dramatically improving card access efficiency.

AI summary
The present invention provides a receiving folder with self-arrangement comprising a top cover and a bottom case. A capacity space is positioned between the top cover and the bottom case. A pair of first sidewalls of the top cover have first inclined edges, clamping units are formed on the first sidewalls. A pair of second sidewalls of the bottom case have second inclined edges. Inner of the bottom case has an elastic unit which end part extending upward to contact inner of the top cover. The back end of the bottom case has at least one plate. Wherein the first inclined edges are opposite to the second inclined edges, thus the first sidewalls are engaged with the second sidewalls.
