Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the mirror is fixed in position, then the structure is simple and stable, but the mirror can only reflect light in a single direction and cannot be adjusted
Solution Approach 1:
The patent transforms the static mirror into a dynamic adjustable component by enabling rotation about two intersecting axes. The mirror can now change its orientation dynamically to reflect light in multiple directions, resolving the contradiction between fixed position stability and adjustment capability.
Solution Approach 2:
The elastic assembly provides self-service functionality by automatically generating pressing force to fix the mirror at adjusted angles without requiring additional positioning devices or complex locking mechanisms. The elastic deformation of the member provides inherent positioning capability.
2Adaptability or versatility
If the mirror is made adjustable, then the detection field of view is enhanced, but the adjustment process becomes complicated requiring additional positioning devices
Solution Approach 1:
The elastic assembly serves itself by using its own elastic deformation to provide pressing force and positioning capability. This eliminates the need for separate positioning devices, simplifying the adjustment process while maintaining enhanced detection field of view through two-axis rotation capability.
Solution Approach 2:
The patent extracts the positioning function from separate positioning devices and integrates it into the elastic assembly itself. The elastic member's deformation characteristics provide inherent positioning capability, removing the need for additional positioning components and simplifying operation.
3Reliability
If additional positioning devices are added to fix the mirror, then the mirror position is stable, but the device complexity increases
Solution Approach 1:
The elastic assembly performs the positioning function through its own elastic deformation characteristics. When the mirror is adjusted to a desired angle, the elastic member's deformation state automatically provides the necessary pressing force to maintain that position, eliminating the need for additional positioning devices while ensuring stability.
Solution Approach 2:
The patent merges the pressing force generation and positioning functions into a single elastic assembly. The elastic member simultaneously provides both the force to hold the mirror in position and the positioning capability through its deformation characteristics, reducing overall device complexity.

Function Achieved in This Case
This solution allows for precise and stable adjustment of the mirror's angle, enhancing the detection field of view and improving the overall efficiency of laser detection systems by allowing the mirror to reflect light from various angles, thus simplifying the adjustment process and maintaining the mirror's position.
Implementation Method 1
an elastic assembly, including an elastic member and a connecting member, where the elastic member abuts against the surface wall of the fixing bracket away from the groove... During the rotation of the adjusting part relative to the fixing bracket, the elastic member provides the adjusting part with a pressing force against the second curved wall via the connecting member
