Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a complex compensation prism structure is used to align optical paths, then the optical paths of the objective lens and laser receiver can be made coaxial, but the device becomes bulky and immobile
Solution Approach 1:
The patent combines the objective lens and laser receiver into a coaxial optical system, merging their optical paths through the spectroscope group. This integration eliminates the need for separate, complex compensation prism structures and reduces overall device volume while maintaining optical alignment.
Solution Approach 2:
The patent uses a spectroscope group with multiple prisms arranged in a specific three-dimensional configuration to redirect and align the optical paths. By utilizing spatial dimensionality and angular reflection, the system achieves coaxial alignment without requiring additional longitudinal space that would increase device volume.
2Ease of operation
If the optical paths are made coaxial using a spectroscope group, then the device becomes portable, but the optical path alignment becomes more complex
Solution Approach 1:
The spectroscope group is divided into multiple discrete prism components (first prism, second prism, third prism) that can be independently manufactured and assembled. This segmentation allows for modular construction, making the complex optical system easier to fabricate, test, and maintain while achieving the desired coaxial alignment for portability.
