Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a blocking plate is installed to prevent optical signal interference, then optical signal interference is reduced, but the reflective surface may be damaged during installation
Solution Approach 1:
The blocking plate is divided into multiple segments that can be independently positioned and secured. This segmentation allows the plate to be installed without applying concentrated force to the reflective surface, thereby preventing damage while effectively blocking optical signal interference between adjacent reflective surfaces
Solution Approach 2:
A mounting frame structure is introduced as an intermediary between the blocking plate and the rotary reflection structure. The frame serves as a mediator that distributes mechanical stress away from the reflective surface, allowing secure installation of the blocking plate without compromising the integrity of the reflective coating
2Object-affected harmful factors
If the blocking plate is securely fixed to prevent interference, then optical signal interference is minimized, but the manufacturing process becomes more complex
Solution Approach 1:
The blocking plate is segmented into multiple sections that can be manufactured separately using standard fabrication processes. Each segment is then assembled into the complete blocking plate structure, simplifying the manufacturing of individual components while achieving the overall goal of preventing optical signal interference
Solution Approach 2:
The mounting frame structure serves multiple functions: it provides structural support for the blocking plate, facilitates easy installation and removal, enables precise positioning, and allows for future maintenance or replacement. This multi-functionality reduces the need for additional specialized components, thereby simplifying the overall manufacturing process
