Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional cable lock with permanently fixed ends is used, then the lock body structure is simple, but the adaptability and versatility are limited
Solution Approach 1:
The cable is divided into modular segments with standardized connection interfaces. Each cable end features a removable locking mechanism that can be independently attached and detached from the lock body, allowing flexible reconfiguration for different locking scenarios while maintaining a relatively simple lock body structure.
Solution Approach 2:
The lock body is designed with universal mounting interfaces and multiple attachment points that can accommodate various cable configurations. The standardized cable connectors enable the same lock body to work with different cable lengths and configurations, providing multi-functionality without significantly increasing structural complexity.
2Ease of repair
If cable ends are permanently fixed to the lock body, then the manufacturing process is simple, but the ease of repair and replacement is poor
Solution Approach 1:
The cable connection system transitions from a static permanent fixation to a dynamic removable connection. The cable ends feature detachable locking mechanisms that can be easily engaged and disengaged, allowing users to replace cables without specialized tools or complex procedures, while the manufacturing process remains relatively straightforward using standardized components.
3Adaptability or versatility
If a non-modular cable design is used, then the device complexity is low, but the adaptability to different locking scenarios is limited
Solution Approach 1:
The cable system is segmented into standardized modular components with uniform connection interfaces. This segmentation enables flexible assembly and disassembly to create different locking configurations appropriate for various scenarios, while the standardization of interfaces prevents excessive complexity by providing repeatable connection patterns.
Solution Approach 2:
The cable system allows parameter changes in length and configuration through modular assembly. Users can adjust the effective cable length and arrangement by attaching or detaching cable segments, enabling adaptation to different locking scenarios without requiring completely different cable systems, thus managing complexity while enhancing versatility.

AI summary
A lock assembly body (220) comprises a housing (224) and lock mechanism (249, 283, 280). The housing (224) has first and second surfaces (221, 222), a pair of spaced apart first locking leg openings (223) defined along the first surface (221) and a pair of spaced apart second locking leg openings (225) defined along the second surface (222). Each of the first and second locking leg openings (223, 225) is configured to receive a locking leg (212) of a locking member. The lock mechanism is within the housing and is associated with each of the first and second locking leg openings such that a locking leg positioned in the respective locking leg opening may be releasably secured by the locking mechanism. A bracket (300) supports the lock assembly.
