Chain Lock with Link Plate Engagement for Compact Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional linkage chain locks, while reducing volume when collapsed, lack consideration for appearance and stability in their design, leading to potential expansion and unsightly bulkiness during storage.
Innovation Solution
A chain lock design featuring a lock body with a socket and a linkage chain formed by link plates, where the second end is secured by a lock core, allowing the chain to be wound around the lock body, with inner sides of link plates engaging the lock body for stability and preventing expansion, and a latch mechanism to secure the second end within a positioning hole.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the linkage chain is made collapsible to reduce volume, then the storage space is reduced, but the appearance becomes bulky and unstable when collapsed
Solution Approach 1:
The linkage chain is designed to wrap around and nest against the lock body when collapsed, with link plates engaging the lock body side surface to maintain a compact, stable appearance during storage
2Volume of moving object
If the linkage chain is made collapsible to reduce volume, then the storage space is reduced, but the chain may expand during storage
Solution Approach 1:
The link plates are designed with engagement features that preemptively prevent expansion by engaging the lock body side surface when the chain is collapsed, counteracting any tendency to expand before it occurs

AI summary
A chain lock is provided. The chain lock includes a lock body and a linkage chain. The lock body has a lock core and a lock body side surface. The linkage chain is formed via linking a plurality of link plates and has a first end and a second end. The first end is joined with the lock body. The second end can be inserted into a socket and secured by the lock core. The linkage chain can be wound around the lock body when the second end is unlocked, and wherein at least one of the plurality of link plates, except the link plates serving as the first end and the second end, engages the lock body side surface when the linkage chain is wound around the lock body.
