Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple laser emitters are packed into a confined region to achieve higher vertical resolution, then angular resolution is improved, but heat dissipation capability deteriorates
Solution Approach 1:
The patent transitions from a two-dimensional planar arrangement of laser emitters to a three-dimensional configuration by positioning emitters at different focal depths along the optical axis. This depth dimension allows lasers to be spatially separated in the Z-direction while maintaining their imaging function, thereby improving heat dissipation without compromising angular resolution.
Solution Approach 2:
The patent divides the laser emitter array into multiple groups or layers positioned at different focal depths. Each group can be independently controlled and optimized, allowing heat management for each subset while maintaining overall high-resolution imaging capability across the entire array.
2Area of stationary object
If more laser emitters are arranged in a confined area to increase field of view, then coverage area is improved, but system reliability deteriorates
Solution Approach 1:
By utilizing the depth dimension (Z-axis) for arranging laser emitters at different focal positions, the system expands the effective field of view without increasing the lateral footprint. This three-dimensional arrangement reduces spatial congestion and improves heat dissipation, thereby enhancing system reliability.
3Volume of moving object
If laser emitters are densely packed to reduce system size, then compactness is improved, but heat dissipation deteriorates
Solution Approach 1:
The patent employs the optical axis direction (Z-dimension) as an additional spatial degree of freedom for arranging laser emitters. This allows the system to maintain a compact lateral footprint while achieving effective heat dissipation through depth-based spatial separation of heat-generating components.
