Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If auxiliary components like glue or screws are used for fixation, then fixation strength is improved, but production cost increases
Solution Approach 1:
The patent integrates the fixation function directly into the buckle member and casing structure by designing engaging parts (protrusions and recesses) that lock together without requiring separate auxiliary components like screws or glue. The buckle member includes first and second engaging parts that directly engage with corresponding features on the casing, merging the fastening function into the structural components themselves.
Solution Approach 2:
The buckle member and casing are designed to self-fixate through their own structural features. The engaging parts on the buckle member automatically engage with corresponding parts on the casing when assembled, and the elastic deformation capability allows the components to self-lock without requiring external fastening agents or additional fastening operations.
2Ease of operation
If hooks are set on mechanical parts for easy disassembly, then ease of operation is improved, but fixation strength deteriorates
Solution Approach 1:
The buckle member is designed with elastic deformation capability, allowing it to dynamically adjust during assembly and disassembly. The elastic part can deform to allow easy insertion and removal, then returns to its original shape to maintain strong fixation during use. This dynamic behavior enables both easy operation and strong fixation at different stages.
Solution Approach 2:
The patent changes the physical state of the buckle member by utilizing elastic deformation. The elastic part transitions between deformed and restored states during assembly and disassembly operations, allowing the fixation strength to be temporarily reduced during operation and then restored during normal use, achieving both ease of operation and strong fixation.
3Ease of operation
If elastic deformation is utilized for easy assembly, then ease of operation is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent utilizes elastic deformation as a parameter change mechanism to accommodate dimensional variations. The elastic part of the buckle member can deform to absorb manufacturing tolerances and fit variations, allowing assembly even when precise dimensional matching is not achieved, thereby reducing the stringency of manufacturing precision requirements while maintaining ease of assembly.
