U-Shaped Card Holder with Elastomeric Polymer and Flexible Cover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing card and paper money holding devices often have gaps, are complicated to handle, and fail to securely retain paper money without additional elements, and U-shaped devices cannot effectively hide the contents from view or block RFID signals.
Innovation Solution
A holding device composed of two rigid, card-shaped plates connected by an elastomeric polymer, with one plate having larger dimensions and recesses for better pressure retention and radio signal blocking, allowing secure insertion into U-shaped holders and daily use as a card or money holder, optionally with a flexible cover.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a U-shaped device is used to hold cards and paper money, then the device can be compact and easy to carry, but the contents are visible to third parties and RFID readers can detect signals
Solution Approach 1:
The patent applies a flexible cover that can be positioned over the U-shaped device to conceal the contents from view. This flexible shell element provides privacy protection while maintaining the compact form factor and ease of carry characteristics of the U-shaped design.
Solution Approach 2:
The patent introduces an intermediary element (the flexible cover) that acts as a barrier between the third parties and the contents of the device. This cover blocks visual access to cards and paper money, and can also provide RFID shielding to prevent detection by external readers.
2Reliability
If additional elements are added to secure paper money in a U-shaped device, then paper money can be retained securely, but the device complexity increases
Solution Approach 1:
The patent merges the paper money retention function with the existing U-shaped structure by utilizing the curved surface and opening configuration of the U-shaped device. The flexible cover is integrated into the overall design, combining multiple functions (concealment, retention, and structural support) into a unified element rather than adding separate discrete components.
3Force
If a rigid structure is used to ensure sufficient holding pressure for cards, then cards can be securely held, but the device cannot be easily inserted into U-shaped holders
Solution Approach 1:
The patent segments the holding device into two main components: a rigid plate structure that provides the necessary holding pressure for cards, and a flexible cover element that enables insertion into U-shaped holders. The rigid plate maintains sufficient force for secure card retention while the flexible cover adapts to the U-shaped holder geometry, allowing easy insertion without compromising the rigid structure's pressure-generating capability.
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 device securely holds cards and paper money with sufficient pressure and prevents RFID reading, allowing easy handling and concealment of contents, enhancing usability and security.
Implementation Method 1
connected to one another by an elastomeric polymer partially along at least two sides of the plates
Implementation Method 2
The elastic band advantageously also encloses an element that the device holds paper money
