Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a supporting framework and mounting supporting frame are manufactured and assembled separately, then the assembly process is simplified and manufacturing flexibility is improved, but the device assembly accuracy deteriorates and dynamic performance becomes difficult to ensure
Solution Approach 1:
The supporting framework is divided into multiple modular components (supporting frame, mounting supporting frame, connecting plates) that can be manufactured separately and assembled. Each component has standardized connection interfaces with positioning features that ensure precise assembly while maintaining manufacturing flexibility.
2Device complexity
If a connecting plate and mounting supporting frame are formed by integral casting, then the assembly process is simplified, but the manufacturing cost increases due to high-level casting and composite processing technology
Solution Approach 1:
The connecting plate and mounting supporting frame are designed as separate components with standardized connection interfaces. This segmentation allows each component to be manufactured using conventional, cost-effective processes while maintaining simple assembly through standardized connections, avoiding the need for expensive integral casting.
Solution Approach 2:
The connecting plate is designed as a universal component with standardized interfaces that can connect different types of supporting frames. This multi-functionality reduces the need for specialized casting operations and allows for modular assembly, lowering manufacturing costs while maintaining assembly simplicity.
3Adaptability or versatility
If multiple components are assembled separately, then manufacturing flexibility and version iteration speed are improved, but the number of assembly factors increases making it difficult to ensure dynamic performance
Solution Approach 1:
The system is segmented into modular components (supporting frame, mounting supporting frame, connecting plates, emitters, detectors) that can be independently manufactured and assembled. This modularity enables rapid version iteration by allowing individual components to be updated without affecting the entire system, while standardized connection interfaces control assembly complexity.
Solution Approach 2:
The connecting plates are designed with adjustable positioning features and flexible connection mechanisms that can adapt to different assembly configurations. This dynamic design allows for easy reconfiguration and version updates while maintaining consistent assembly procedures, balancing adaptability with controlled complexity.
