Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional integral locking device is used, then the structural integrity is maintained, but the replacement difficulty increases and waste increases when damaged
Solution Approach 1:
The locking device is divided into multiple independent components: a locking base, a clamping base, and a fastening assembly. These segmented parts can be independently replaced when damaged, eliminating the need to replace the entire locking device while maintaining structural integrity through precise matching interfaces and positioning holes.
2Reliability
If a conventional integral locking device is used, then the structural integrity is maintained, but the material waste increases when damaged
Solution Approach 1:
By segmenting the locking device into replaceable components, only the damaged portion needs to be replaced rather than the entire device. This significantly reduces material waste while preserving the integrity of the undamaged components through standardized interfaces.
3Ease of repair
If a detachable locking device with multiple parts is used, then the ease of replacement is improved, but the device complexity increases
Solution Approach 1:
The detachable locking device uses merging principles by combining multiple simple components (locking base, clamping base, fastening assembly) into a cohesive unit that achieves ease of replacement. The components are designed with simple geometric shapes and standardized fastening mechanisms that simplify assembly and disassembly operations.
4Ease of repair
If a detachable locking device with multiple parts is used, then the ease of replacement is improved, but the manufacturing complexity increases
Solution Approach 1:
Segmenting the locking device into separate components allows each part to be manufactured independently using simpler processes. The locking base, clamping base, and fastening assembly can be produced separately and then assembled, reducing the complexity of any single manufacturing operation while enabling easier replacement of individual parts.
