Card Storage Device With Stepped Pushing Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional card storage devices require manual rummaging to retrieve specific cards, which is inconvenient.
Innovation Solution
A card storage device featuring a housing with a sliding piece and card pushing piece, where step portions on the pushing piece allow cards to be easily distinguished and extracted by rotating the piece, eliminating the need for manual retrieval.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If cards are stored in a compact card storage device, then portability is improved, but card retrieval convenience deteriorates
Solution Approach 1:
The card pushing piece is designed to be rotatable, transforming the static card storage structure into a dynamic one. When the card pushing piece rotates, it automatically pushes cards toward the opening, enabling convenient retrieval without manual rummaging while maintaining a compact form factor.
Solution Approach 2:
The card storage device performs self-service by automatically pushing cards outward when the card pushing piece rotates. The device itself carries out the card retrieval action without requiring users to manually search through and extract cards, thus improving convenience while keeping the device compact.
2Device complexity
If a simple sliding mechanism is used, then device complexity is reduced, but automatic resetting function is lost
Solution Approach 1:
The elastic piece is integrated with the card pushing piece, merging the resetting function into the existing structure. This combination allows the card pushing piece to automatically return to its initial position after card ejection without adding a separate complex resetting mechanism, thus maintaining simplicity while achieving automatic resetting.
Solution Approach 2:
The elastic piece provides self-service by automatically restoring the card pushing piece to its initial position after rotation. This elastic recovery mechanism enables the device to reset itself without external intervention, achieving automatic resetting with minimal added complexity.
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
Enables quick and convenient access to specific cards by arranging them in steps, allowing automatic resetting of the device, reducing user effort in handling.
Implementation Method 1
a first end of the elastic piece is connected to the fixing shaft. A second end of the elastic piece is connected to the limiting hole. When the sliding piece moves in the direction away from the base, the sliding structure pushes the card pushing piece to rotate in the direction away from the base and the elastic piece extends. When the elastic piece is reset, the elastic piece pulls the card pushing piece to rotate in the direction close to the base

AI summary
A card storage device includes a housing defining an accommodating cavity, a sliding piece slidably connected to the housing, and a card pushing piece arranged in the housing. The accommodating cavity penetrates the housing. The card pushing piece is connected to the sliding piece. The card pushing piece and the accommodating cavity are enclosed to form an accommodating groove. Step portions are arranged on at least one side of the card pushing piece. The step portions are arranged in steps. When the sliding piece moves toward an opening of the accommodating groove. The sliding piece drives the card pushing piece to move toward the opening of the accommodating groove. When the card pushing piece moves in a direction away from the opening of the accommodating groove, the card pushing piece drives the sliding piece to move in the direction away from the opening of the accommodating groove.
