Card Storage Box Covering Clamping Plate Limiting Groove
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing card storage solutions fail to effectively prevent cards from falling off over time due to reduced holding and restricting effects, leading to user inconvenience and card loss.
Innovation Solution
A card storage box design featuring a closed cover body with a clamping plate and limiting groove mechanism, combined with a magnet and card pushing member, allows for secure card storage and easy retrieval, using rotating and spring-loaded components for convenient operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cover body is provided to prevent cards from falling off, then card security is improved, but card retrieval convenience deteriorates
Solution Approach 1:
The clamping plate is designed to be movable between a clamping position (where it engages with the limiting groove to secure the cover body) and a released position (where it disengages to allow cover body movement). This dynamic mechanism enables the system to switch between secure storage and convenient retrieval states, resolving the contradiction between card security and retrieval convenience.
2Ease of operation
If the holding and restricting effect is reduced after long-term use or damage, then device durability worsens, but card accessibility improves
Solution Approach 1:
The card pushing member is designed to automatically push cards outward when the cover body moves to the opened position, eliminating the need for manual card extraction. This self-service mechanism ensures consistent card accessibility regardless of the holding effect degradation over time, maintaining ease of operation while the durable clamping mechanism continues to provide reliable security.
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 design prevents card loss by securely locking the cover body over the opening, allowing easy insertion and retrieval of cards, enhancing user experience through secure storage and intuitive operation.
Implementation Method 1
a magnet is arranged on the side wall of the housing
Implementation Method 2
The cover body is connected to the housing through a rotating shaft, the rotating shaft is sleeved with a first reset torsion spring

AI summary
A card storage box is disclosed. The card storage box includes a housing having a cavity, where the housing is provided with an opening at a top, a clamping plate is slidably connected to a side wall of the housing and partially extends out of the opening, a card pushing member is rotatably connected to the housing and positioned at a bottom of the cavity. The card storage box further includes a cover body, where the cover body is rotatably connected to the housing, and the cover body can cover the opening. A limiting groove is provided in an inner wall of the cover body, when the cover body covers the housing, the clamping plate is clamped with the limiting groove, and the clamping plate abuts against a groove wall of the limiting groove to limit a rotation of the cover body.
