Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If display devices are integrated into external application units, then visual information display capability is improved, but device complexity and assembly difficulty increase
Solution Approach 1:
The display device is divided into separate functional modules: a first housing containing the illumination device and optical display, a second housing for the external application unit, and distinct mechanical and data interfaces. This modular segmentation allows independent assembly and reduces overall complexity while maintaining full visual information display capability through the coordinated operation of separate components.
2Loss of information
If display devices are integrated into external application units, then visual information display capability is improved, but manufacturing cost increases
Solution Approach 1:
The first housing with illumination device and optical display is designed as a universal module that can be attached to various external application units through standardized mechanical interfaces. This multi-functionality allows the same display module to serve different applications, reducing per-unit manufacturing costs through economies of scale and standardized production processes.
3Ease of manufacture
If modular design is implemented, then ease of assembly and manufacturing cost are improved, but connection reliability and data transmission stability may worsen
Solution Approach 1:
The mechanical interface and data interface are combined in a integrated connector assembly that simultaneously establishes both physical connection and electrical/data connections when the first housing is attached to the second housing. This merging ensures that connection reliability and data transmission stability are maintained while preserving the benefits of modular design and ease of assembly.
