Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a detachable lock device is designed with easy assembly and disassembly, then the ease of operation is improved, but the structural complexity increases due to the need for connecting assemblies and multiple clamping plates
Solution Approach 1:
The lock device is divided into separate modular components: upper clamping plate, lower clamping plate, connecting assembly, and locking assembly. Each component performs a specific function and can be independently manufactured and assembled, enabling easy assembly and disassembly while maintaining manageable structural complexity through functional segmentation
Solution Approach 2:
The connecting assembly serves multiple functions: it connects the upper and lower clamping plates, provides threading for the hand screw, and enables both assembly and disassembly operations. This multi-functionality reduces the need for separate components, thereby managing structural complexity while maintaining ease of operation
2Reliability
If a mechanical combination lock is integrated into the locking assembly, then the security and reliability are improved, but the device complexity increases due to additional locking mechanisms
Solution Approach 1:
The mechanical combination lock is integrated directly into the locking assembly, merging the locking function with the combination mechanism. This consolidation provides enhanced security through a reliable mechanical locking system while managing device complexity by combining functions into a unified assembly rather than adding separate components
Solution Approach 2:
The hand screw acts as an intermediary mechanism that translates the rotational motion from the combination lock into the linear motion required to engage or disengage the locking mechanism. This intermediary component enables secure locking through the combination mechanism while maintaining a relatively simple overall structure
3Stability of the object's composition
If the upper clamping plate is locked at the clamping position relative to the lower clamping plate, then the stability is improved, but the ease of operation deteriorates due to the need for threaded connections and hand screws
Solution Approach 1:
The connecting assembly with hand screw provides a dynamic connection that can be easily transitioned between locked and unlocked states. The threaded connection maintains stable locking when engaged, while the same mechanism allows quick disassembly by simply reversing the screwing action, thus balancing stability with ease of operation

Function Achieved in This Case
The detachable lock device provides a secure and easy-to-use solution for temporarily locking zippers, offering a detachable connection that can be fixed on any device with a zipper, enhancing safety and security.
Implementation Method 1
the connecting assembly includes a threaded hole and a hand screw, the threaded hole is arranged on the upper clamping plate, the lower clamping plate has a locking hole, the hand screw passes through the locking hole and connects with the threaded hole, and the upper clamping plate is locked at the clamping position relative to the lower clamping plate

AI summary
A detachable lock device with a combination lock includes a lower clamping plate, a locking assembly, a connecting assembly and an upper clamping plate. The upper clamping plate has a clamping position for clamping a zipper and an unclamping position for releasing the zipper, and the upper clamping plate is connected to the lower clamping plate through the connecting assembly, so that the upper clamping plate is locked at the clamping position relative to the lower clamping plate. The locking assembly has a rotatable encircling member, a locking area for locking a zipper slider, the zipper slider is locked in the locking area or the locking area is opened by rotating the encircling member, and the locking assembly includes a mechanical combination lock for locking or unlocking the encircling member. The detachable lock device has easy disassembly and assembly and simple structure.
