Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a blocking plate is installed to prevent optical signal interference, then interference prevention is improved, but the risk of damage to the reflective surface increases
Solution Approach 1:
The patent introduces a blocking plate as an intermediary component positioned between the first and second reflectors. This blocking plate prevents direct optical signal interference while being designed with specific geometric features (recessed region) that prevent contact with the reflective surfaces, thus eliminating damage risk while maintaining interference prevention functionality
2Adaptability or versatility
If multiple reflectors are used to expand detection range, then detection coverage is improved, but angular errors between reflectors increase
Solution Approach 1:
The patent merges the first and second reflectors with the blocking plate into a single integrated structure where all three components are formed as one piece. This integration ensures that the reflectors maintain precise angular relationships with each other, eliminating angular errors that would otherwise occur during separate manufacturing and assembly processes
Solution Approach 2:
The integrated structure is designed with distinct functional segments (first reflector, second reflector, blocking plate) that can be independently defined in the design phase, allowing each component to perform its specific function while maintaining precise relative positioning through the integrated manufacturing process
3Manufacturing precision
If a complex coupling mechanism is used to synchronize reflector rotation, then angular precision is improved, but manufacturing complexity increases
Solution Approach 1:
The patent combines the blocking plate with the reflectors into a single integrated component that rotates as one unit. This merging eliminates the need for complex coupling mechanisms, as the integrated structure naturally maintains synchronous rotation without requiring additional coupling parts or complex assembly procedures
