Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing card and note holding devices are complex to produce, require significant material and weight, and lack ease of card removal and secure storage.
Innovation Solution
A simplified holding device with a one-piece housing and integral spring-elastic clip design, featuring asymmetrical side ridges and a large cut-out for easy card access and removal, minimizing material use and weight while ensuring secure clamping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a multi-component housing design with separate top part, bottom part, and clip is used, then secure clamping of cards and notes is achieved, but production complexity increases significantly
Solution Approach 1:
The patent combines the top part, bottom part, and clip into a single integrated housing component. The clip is formed as an integral part of the housing, eliminating the need for separate components and joining operations. This merging reduces production complexity while maintaining the secure clamping function through the integrated spring-elastic clip structure.
2Stability of the object's composition
If multiple joining measures and molding tools are used for assembling components, then structural integrity is maintained, but manufacturing complexity and cost increase
Solution Approach 1:
The housing is produced as a single molded piece with the clip integrated into the structure. This eliminates the need for multiple molding tools and joining operations, simplifying manufacturing while maintaining structural integrity through the monolithic construction.
3Reliability
If a traditional multi-component design is used, then functional storage is achieved, but material usage and overall weight increase
Solution Approach 1:
The integrated housing design eliminates redundant materials from separate components and joining elements. The single-piece construction with integrated clip reduces overall material usage while maintaining all necessary storage and clamping functions.
4Reliability
If cards are securely clamped in the housing, then storage security is improved, but ease of card removal becomes difficult
Solution Approach 1:
The spring-elastic clip provides dynamic clamping force that automatically adjusts. When a card is inserted, the clip flexes and applies securing force. When removal is attempted, the card can be easily pulled out by lifting it slightly, which releases the clip's grip, allowing smooth removal while maintaining secure storage during normal use.
5Reliability
If the housing is designed as a complete enclosed structure, then protection is improved, but ease of access and removal of cards deteriorates
Solution Approach 1:
The housing incorporates openings and access points that segment the enclosed structure. These openings allow easy insertion and removal of cards while the rest of the housing remains enclosed to provide protection. The clip mechanism is accessible through these openings, enabling card access without compromising overall protection.
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 solution enables easy insertion and removal of cards and notes with reduced material usage and weight, providing secure storage and clamping without additional retaining means.
Implementation Method 1
The holding device comprises a housing (2) and a clip (4) connected, particularly integrally, thereto, and/or a single clip (4)... Both the notes and the cards are clamped in the housing by way of the clip or clips... When a card and/or a note is inserted, the spring-elastic clip is lifted and biased, so that thereafter even just a single card is held securely or clamped in the housing thereafter as a result of the bias.

AI summary
A holding device for cards and/or notes includes a housing, which includes at least one clip and a base. The holding device is so designed that production is simplified, wherein secure storage of individual or multiple cards and/or notes is made possible. To this end, the base of the housing, which is open at the top toward the at least one clip, includes upwardly projecting side ridges, which are disposed at a distance from each other and, if no cards or notes are disposed in the housing, each of the at least one clip is located partially between the side ridges and has a free end extending at least approximately to the bottom plane of the base.
