Nested Lock Catch Structure for Chess Piece Boxes Against Dust
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mechanical locks for storage boxes of chess pieces suffer from instability over time, leading to locking difficulties due to abrasion and dust accumulation, which compromises their functionality.
Innovation Solution
A lock catch structure comprising an upper catch assembly with a connecting buckle and a lower match assembly, featuring a rotating mechanism and a lock cylinder, which ensures stable locking by accommodating fixing components within an accommodating cavity and preventing dust entry through a cover plate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the lock structure has a relatively large gap when working to lock the storage box, then it is easier to assemble and operate, but the lock structure becomes unstable and loses locking function due to abrasion over time
Solution Approach 1:
The first fixing component and second fixing component are nested within the accommodating cavity of the connecting buckle when locked, with the lock cylinder inserted into the connecting portion. This nesting structure reduces the gap between locking components while maintaining ease of operation, resolving the contradiction between operational ease and locking stability.
2Reliability
If the lock structure has a relatively small gap when working to lock the storage box, then locking stability is improved, but dust easily enters the lock structure to form dirt causing locking difficulty
Solution Approach 1:
The dust-proof cover is separated from the main lock structure, allowing it to be independently installed over the accommodating cavity. This extraction enables the dust-proof function to be added without compromising the small gap design needed for locking stability, effectively preventing dust accumulation while maintaining reliable locking.
3Reliability
If a traditional mechanical lock structure is used for the storage box, then locking function is provided, but the structure becomes complex and requires corresponding keys for unlocking bringing inconvenience
Solution Approach 1:
The lock structure is segmented into independent functional components: the connecting buckle with accommodating cavity, the first fixing component, the second fixing component, and the dust-proof cover. This segmentation simplifies the overall structure, eliminating the need for complex key mechanisms while maintaining reliable locking function through the rotational engagement of simplified components.

AI summary
A lock catch structure and a storage box of chess pieces are provided. The lock catch structure includes a connecting buckle, a first fixing component, a lock cylinder, and a second fixing component. The connecting buckle is rotatably connected to the first fixing component, and the first fixing component is connected to a first end of a locked object. The lock cylinder is inserted into the second fixing component, and the second fixing component is connected to a second end of the locked object. The connecting buckle defines an accommodating cavity for accommodating the first fixing component and the second fixing component, the first fixing component and the second fixing component lock the first end of the locked object and the second end of the locked object.
