Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lock mechanisms for slide rail assemblies and similar applications often require complex configurations with electronic components and springs, which may not adequately meet diverse market requirements or structural operations for locking movable objects relative to fixed objects.
Innovation Solution
A lock mechanism comprising a driving device, a locking member, a linkage member, and an elastic member, where the locking member is driven to linearly move between locking and unlocking positions, allowing for electronic or manual control, and is detachably connected to the objects, with a sensor to detect predetermined positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a lock mechanism uses electronic components and springs for locking and unlocking, then the locking function can be achieved, but the structure becomes complex
Solution Approach 1:
The patent extracts the spring component from the traditional lock mechanism and replaces it with an elastic member that integrates the elastic function directly into the locking assembly. This reduces the number of separate components while maintaining the locking function, thereby simplifying the overall structure.
Solution Approach 2:
The patent merges the elastic member with the locking member into a unified structure where the elastic member is disposed between the locking member and the first object. This integration eliminates the need for separate spring assemblies and reduces structural complexity while preserving the locking and unlocking functions.
2Reliability
If a lock mechanism is designed for specific applications, then the locking function is reliable, but the adaptability to different applications is reduced
Solution Approach 1:
The patent designs the lock mechanism with a universal structure that can be applied to various objects movable relative to each other. The locking member, elastic member, and driving device are configured in a way that allows the mechanism to adapt to different applications (e.g., drawer-cabinet, door-frame) without requiring fundamental design changes, thereby enhancing versatility while maintaining reliable locking function.
3Reliability
If a lock mechanism uses rotational movement of latch receiver and lever arm, then the locking function is achieved, but the structure becomes complex and may not meet diverse market requirements
Solution Approach 1:
Instead of using rotational movement of a latch receiver and lever arm, the patent inverts the approach by using linear movement of a locking member along a guide. The locking member moves linearly between locked and unlocked positions, which simplifies the mechanical structure and eliminates the need for complex rotational linkages while achieving the same locking function.
Solution Approach 2:
The patent replaces the traditional mechanical system of rotational latch receiver and lever arm with a simplified linear motion system driven by a driving device. This substitution reduces mechanical complexity while maintaining the essential locking function, making the mechanism more adaptable to diverse market requirements.

AI summary
A lock mechanism is configured to be arranged on one of a first object and a second object movable relative to each other. The lock mechanism includes a driving device and a locking member. The locking member is configured to be driven by the driving device to move between a first position and a second position in a non-rotatable manner. When the locking member is located at the first position, the locking member is configured to lock the other one of the first object and the second object. When the locking member is located at the second position, the locking member is does not lock the other one of the first object and the second object.
