Lock Set Transmission Mechanism With Universal Driving Ribs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lock set mechanisms lack design flexibility and production efficiency due to the inability of lock cores to cooperate with different transmission rods, limiting their applicability across various types of lock sets.
Innovation Solution
A lock set transmission mechanism comprising a lock core, transmission rod, supporting member, and fixing member, where the lock core is arranged on a lock case and driven by a key to rotate, with a supporting member and fixing member configuration allowing the transmission rod to be driven synchronously, enabling cooperation with different transmission rods and types of locks through various supporting structures and mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the lock core is designed with a specific driving structure for a particular transmission rod, then the locking function is reliable, but the adaptability to different transmission rod types is reduced
Solution Approach 1:
The lock core is designed with a universal driving structure comprising a driving ring and multiple driving ribs that can accommodate different transmission rod types (first transmission rod with first driving structure, second transmission rod with second driving structure). The driving ribs can engage with different driving structures on different transmission rods, allowing the same lock core to perform reliable locking functions with multiple transmission rod variants.
Solution Approach 2:
The driving structure is segmented into independent driving ribs on the driving ring, where each driving rib can independently engage with different driving structures on different transmission rods. This segmentation allows the lock core to adapt to various transmission rod types while maintaining reliable locking functionality through the modular engagement mechanism.
2Adaptability or versatility
If different driving structures are designed for different transmission rod types, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
Instead of designing separate lock cores for different transmission rod types, a single universal lock core with a multi-functional driving structure is used. The driving ring with multiple driving ribs can engage with different transmission rod driving structures (first driving structure, second driving structure) without requiring different lock core designs, thereby reducing device complexity while maintaining adaptability.
Solution Approach 2:
The driving structure employs dynamic engagement where the driving ribs on the driving ring can adaptively engage with different driving structures on different transmission rods. This dynamic capability allows the same driving structure to accommodate various transmission rod types without increasing complexity, as the engagement mechanism naturally adapts to different configurations.
3Ease of manufacture
If the lock core is fixed to a specific transmission rod, then the manufacturing process is simplified, but the production efficiency is reduced due to inability to reuse lock cores
Solution Approach 1:
The lock core is designed as a universal component that can be assembled with different transmission rod types (first transmission rod, second transmission rod) through its multi-functional driving structure. This universality allows the same lock core to be reused across different transmission rod variants, significantly improving production efficiency by reducing the number of unique lock core inventories needed while keeping the manufacturing process simple through standardized assembly procedures.
4Adaptability or versatility
If a universal driving structure is designed to accommodate different transmission rods, then the adaptability is improved, but the driving precision may be compromised
Solution Approach 1:
The driving structure employs local quality optimization where each driving rib on the driving ring is specifically designed with engagement features tailored for different transmission rod driving structures. This localized design ensures that each engagement point maintains high driving precision for its specific transmission rod type, while the overall system remains adaptable to multiple transmission rod variants through the modular driving rib configuration.

AI summary
A lock set transmission mechanism includes a lock case, a lock core, a transmission rod, a supporting member and a fixing member. The lock core is arranged on the lock case and configured to be driven by a key to rotate relative to the lock case. The transmission rod has a first end configured to be connected to a latch, and a second end. The supporting member includes a first supporting ring sleeved on the lock core, a second supporting ring configured to support the second end of the transmission rod, and at least one supporting rib connected to the first and second supporting rings. The fixing member is configured to fix the supporting member to the lock core. Wherein, when the lock core is rotated relative to the lock case, the transmission rod is driven by the lock core to rotate, in order to move the latch.
