Lock Clutch Interchanging Mechanism for Door Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current lock clutch devices lack a simple and cost-effective mechanism for seamlessly interchanging between left and right door opening configurations, leading to complexity and increased production costs.
Innovation Solution
A mechanical structure comprising a clutch pin, rotary clutch shafts, and stop edges that allow the clutch pin to extend or retract, enabling the lock to function differently based on door orientation, with specific stop edges interacting to facilitate forward and backward rotations and locking mechanisms for both left and right openings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional lock clutch device is used without interchanging capability, then the structure is simple and production cost is low, but the device cannot adapt to both left and right door operations
Solution Approach 1:
The clutch shaft is designed to be rotatable relative to the lock body, allowing it to dynamically adjust its orientation between left-door and right-door configurations. This dynamic adjustment capability enables a single lock clutch device to adapt to different door opening directions without requiring separate devices for each configuration.
Solution Approach 2:
The lock clutch device incorporates a universal design where the clutch shaft can serve multiple functions by rotating to different positions. The same clutch mechanism handles both left-door and right-door operations, eliminating the need for separate clutch devices for each door configuration and thereby reducing overall system complexity.
2Adaptability or versatility
If a traditional lock clutch device is used without interchanging capability, then the production cost is low, but the device cannot seamlessly switch between left and right door operations
Solution Approach 1:
The rotatable clutch shaft design allows a single manufactured component to dynamically adapt to different door configurations through rotation, eliminating the need to manufacture separate clutch devices for left and right doors. This reduces production costs while maintaining full interchanging capability.
Solution Approach 2:
By designing the clutch shaft to be universally applicable to both left and right door operations through rotation, the invention reduces the total number of parts that need to be manufactured. This universal design lowers production costs while ensuring seamless switching between different door configurations.
3Reliability
If the clutch pin is always extended, then the locking function is always engaged, but the door cannot rotate freely in both directions
Solution Approach 1:
The clutch pin is designed to move dynamically between extended and retracted positions based on the operational requirements. When the door needs to rotate freely, the clutch pin retracts to disengage the locking function. When secure locking is required, the clutch pin extends to engage the locking function. This dynamic positioning ensures both reliable locking and free door rotation when needed.
Solution Approach 2:
The clutch pin can be preliminarily positioned in the retracted state to prevent unwanted locking during door rotation operations. This preliminary positioning ensures that the door can rotate freely in both directions without accidental engagement of the locking function, while still allowing the locking function to be activated when required.

AI summary
A left and right interchanging device for a lock clutch includes a clutch pin, an inner rotary clutch shaft, and an outer rotary clutch shaft. The clutch pin is movably placed in a hole of the inner rotary clutch shaft and connected with a built-in driving module of the inner rotary clutch shaft. The module controls the clutch pin so that the clutch pin can retract into or extend out of the inner rotary clutch shaft. The inner rotary clutch shaft is placed in a central hole of the outer rotary clutch shaft, and both can rotate about a same central axis. A first stop edge and a second stop edge are provided on the inner rotary clutch shaft and connected with a driving output shaft. A third stop edge and a fourth stop edge are provided on the outer rotary clutch shaft and connected with a driving output and input shaft. When a door is left-opened, the third stop edge correspondingly contacts the clutch pin and the fourth stop edge correspondingly contacts the second stop edge. When the door is right-opened, the third stop edge contacts the second stop edge, and the fourth stop edge contacts the clutch pin.
