Lock Main Body Slide Slot Replacement Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional locks are difficult and costly to replace when a user loses their key, as the main body and sleeve member must be disassembled together, making the replacement process complicated and expensive.
Innovation Solution
A lock design featuring a sleeve member, a main body with a slide slot and protrusive block, and an engaging member with a hook and slot, allowing the main body to be singularly disassembled and replaced without removing the sleeve member, enabling easier and more cost-effective replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the main body is undetachably assembled on the sleeve member, then the lock structure is stable and reliable, but the replacement process becomes complicated and costly
Solution Approach 1:
The lock is divided into separable components: the sleeve member (1) remains fixed on the object, while the main body (2) can be independently removed through the slide slot (41) and protrusive block (42) mechanism. This segmentation allows the main body to be replaced without removing the entire lock assembly, resolving the contradiction between structural stability and replacement ease.
2Strength
If the main body and sleeve member are disassembled together for replacement, then the connection between components is secure, but the replacement time and cost increase
Solution Approach 1:
The main body (2) is extracted as a separate replaceable component from the lock assembly. The slide slot (41) and protrusive block (42) enable the main body to be removed independently while the sleeve member (1) remains in place. This extraction principle reduces replacement time by eliminating the need to disassemble the entire lock, while maintaining connection strength through the engaging member (3) and its connecting portions.

AI summary
A lock is provided, including a sleeve member, a main body and an engaging member. The main body is rotatably disposed in the sleeve member and has a first connecting portion, one of the main body and the sleeve member has a slide slot which extends along an axial direction and the other has a protrusive block, when the protrusive block corresponds to the slide slot in the axial direction, the main body is movable relative to detachable from the sleeve member. The engaging member is rotatably disposed in the sleeve member and has a second connecting portion, one of the engaging member and the main body has a hook and the other has a slot, when the first and second connecting portions are assembled to each other, the engaging member and the main body are co-rotatable, and the hook is engaged with the slot.
