Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the reflection unit is integrated into the support shaft as a single component, then the device structure is simplified, but the manufacturing cost increases and assembly complexity increases to protect reflection surfaces
Solution Approach 1:
The device is divided into separate functional modules: the support shaft and the reflection unit are independent components that can be manufactured separately and assembled together. This segmentation allows each component to be optimized for its specific function, reducing overall manufacturing cost while maintaining structural simplicity.
Solution Approach 2:
The reflection unit is extracted from the support shaft structure, allowing it to be produced independently using more cost-effective methods. This extraction eliminates the need for expensive integrated manufacturing processes while simplifying the support shaft design.
2Reliability
If the reflection unit is integrated into the support shaft, then the device appears more robust, but the assembly process becomes complex requiring protection of reflection surfaces
Solution Approach 1:
By segmenting the device into separate modules, the assembly process becomes more straightforward. Each module can be pre-assembled and tested independently, then combined without requiring complex protection measures for reflection surfaces during assembly.
Solution Approach 2:
The separate reflection unit design allows for self-contained assembly of each component before final integration. The reflection surfaces are protected within their own module during manufacturing and assembly, eliminating the need for special protection measures during the main assembly process.
3Adaptability or versatility
If the reflection unit is separate from the support shaft, then modularity is improved and assembly is simplified, but the device may appear less robust
Solution Approach 1:
The segmented design provides modularity while maintaining robustness through standardized connection interfaces. Each module remains structurally sound on its own, and the connection between modules is designed to be as strong as the individual components.
Solution Approach 2:
The separate modules are combined through a robust connection mechanism that integrates them into a unified, stable structure. The combination maintains the robustness of individual components while adding the benefits of modularity and simplified assembly.
