Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If specialized machining tools are used for each vane design, then machining accuracy is improved, but device complexity and lack of versatility worsen
Solution Approach 1:
The fixation mechanism is designed with adjustable fixation members that can accommodate multiple vane designs and root configurations through a single apparatus, eliminating the need for specialized tools for each design while maintaining machining accuracy
2Reliability
If fixed installation of machining apparatus is used, then machining stability is improved, but portability and adaptability to different fabrication sites worsen
Solution Approach 1:
The machining apparatus is divided into modular components including the fixation mechanism and machining device that can be easily assembled and disassembled, allowing the system to be transported to different fabrication sites while maintaining stability during operation
3Reliability
If heavy-duty fixation mechanisms are used, then component retention reliability is improved, but device weight and transportability worsen
Solution Approach 1:
The fixation mechanism uses adjustable and movable fixation members that can adapt to different component sizes and shapes, providing reliable retention through dynamic adjustment rather than relying on excessive weight or fixed rigid structures
