Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If indirect positioning method is used to mount primary and secondary optical element assemblies on a radiator, then the structure becomes more flexible, but the positioning precision and mounting reliability deteriorate
Solution Approach 1:
The patent merges the primary optical element assembly and secondary optical element assembly into a unified integrated structure where the secondary assembly is directly mounted on the primary assembly. This combination eliminates the need for separate mounting on the radiator, directly resolving the contradiction by achieving both structural flexibility and high positioning precision through integration.
Solution Approach 2:
The primary optical element assembly serves as an intermediary between the radiator and the secondary optical element assembly. Instead of mounting both assemblies directly on the radiator, the primary assembly acts as a mediator that carries the secondary assembly, thereby achieving precise positioning while maintaining structural flexibility.
2Ease of operation
If indirect positioning method is used to mount optical element assemblies, then mounting flexibility is improved, but mounting reliability deteriorates due to large mounting errors
Solution Approach 1:
By combining the mounting functions into a single integrated structure where the secondary assembly is mounted on the primary assembly, the patent eliminates multiple mounting operations that accumulate errors. This merging approach maintains mounting flexibility while significantly improving mounting reliability by reducing the number of independent mounting interfaces.
3Weight of moving object
If separate mounting of primary and secondary optical element assemblies is used, then assembly independence is improved, but the light shape accuracy deteriorates
Solution Approach 1:
The patent merges the positioning functions of the primary and secondary assemblies into a direct mounting relationship, eliminating the need for separate positioning references. This integration ensures that the relative positions of optical elements are precisely controlled, thereby improving light shape accuracy while maintaining design flexibility through modular assembly.
