Connecting Buckle Zipper Lock for Variable Zipper Head Sizes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing zipper locks with connecting buckles are limited in their ability to adapt to zipper heads of varying sizes due to size mismatches, leading to compatibility issues and increased theft or damage risks.
Innovation Solution
A zipper lock with a connecting buckle that includes a lock head clamping plate, a lock device, and a detachable connecting buckle, allowing the lock device to indirectly lock the zipper head by securing the connecting buckle to the fixed handle, which can accommodate different zipper head sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the zipper lock directly locks to a hole in the movable part of a zipper head, then the locking function is achieved, but the compatibility with zipper heads of different sizes is poor
Solution Approach 1:
The patent introduces a connecting buckle as an intermediary component between the lock device and the zipper head. The connecting buckle includes a buckle body with a receiving cavity that can accommodate the fixed handle of the zipper head, and a connecting end that connects to the lock device. This intermediary structure allows the lock to adapt to zipper heads of various sizes without requiring direct connection to the movable part, thereby resolving the compatibility issue while maintaining reliable locking function.
2Ease of manufacture
If the zipper lock uses a fixed-size connection mechanism, then the manufacturing cost is low, but the adaptability to various zipper head sizes is limited
Solution Approach 1:
The patent employs dynamic adjustment mechanisms within the connecting buckle to enable adaptation to different zipper head sizes. The connecting buckle includes adjustable components that can be modified to accommodate varying dimensions of the fixed handle. This dynamic capability allows a single lock design to work with multiple zipper head sizes without requiring multiple specialized locks, thus maintaining ease of manufacture while improving adaptability.
3Device complexity
If the zipper lock directly engages with the movable handle, then the structure is simple, but the locking reliability for different zipper types is insufficient
Solution Approach 1:
The patent designs the connecting buckle with universal functionality to work with different zipper types. The receiving cavity is designed to accommodate various shapes and sizes of fixed handles, and the locking mechanism can engage with different zipper configurations. This universal design approach maintains relatively simple structure while significantly improving locking reliability across diverse zipper types by eliminating the need for type-specific locks.
