Sliding Card Holder With Pressure Relief Wheel and Card Ejection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing card holders primarily serve as storage devices, lacking features that enhance user experience and convenience, particularly in terms of relaxation and ease of access to cards.
Innovation Solution
A card holder design featuring a housing with a sliding cover plate and rotatable pressure relief wheel, a card pusher mechanism, and a card tape structure, allowing for easy access and temporary storage of cards while providing a relaxing playing experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a card holder only has a storage function, then the structure is simple, but the user experience and relaxation are poor
Solution Approach 1:
The card holder integrates multiple functions including storage, sliding mechanism for card access, and a rotatable pressure relief wheel for relaxation. The cover plate can slide along the housing to open/close the holder, while the pressure relief wheel on the cover plate can be rotated independently to provide tactile feedback and relaxation, making the device serve both practical storage purposes and entertainment functions.
2Ease of operation
If cards are stored in a card holder, then cards are protected, but access to cards requires opening the entire holder
Solution Approach 1:
The card holder is divided into a fixed housing and a movable cover plate that can slide independently along the housing. This segmentation allows the cover plate to be opened partially to access cards without opening the entire holder structure, enabling selective access to specific card slots while maintaining protection for other cards.
3Strength
If the cover plate and housing are rigid, then cards are protected from deformation, but sliding operation may be difficult
Solution Approach 1:
A sliding bar is introduced as an intermediary component between the cover plate and housing. The sliding bar engages with grooves or guides in the housing, providing a mechanical pathway that enables smooth sliding motion of the rigid cover plate along the housing while maintaining the rigidity needed for card 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
Enhances user relaxation through a rotatable pressure relief wheel and facilitates quick access to cards via a sliding mechanism, while protecting cards from deformation and offering temporary storage solutions.
Implementation Method 1
The assembly ring is movably provided with a pressure relief wheel by means of a bearing
Implementation Method 2
Top columns and first springs are movably mounted in the first assembly holes. The first springs elastically abut against the top columns.
Implementation Method 3
The sliding bars are slidably connected to the sliding recesses
