Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate observation and laser emission/reception channels are used, then distance measurement and observation functions are achieved, but alignment stability deteriorates during shocks or vibrations
Solution Approach 1:
The patent merges the observation channel and laser emission/reception channels into a single integrated optical channel. The optical element (beam splitter) combines the functions of receiving observation light and transmitting laser radiation through the same physical pathway, ensuring that both functions share identical alignment references. This integration eliminates the misalignment problem that occurs in separate channels during shocks or vibrations, as both observation and ranging operations are performed through the same optical axis.
2Measurement precision
If bulky systems are used for observation with laser illumination, then distance measurement and illumination functions are achieved, but portability deteriorates
Solution Approach 1:
The patent combines multiple functions (observation, laser illumination, distance measurement) into a single integrated system using a unified optical channel. By sharing the optical pathway and using a single optical element for both observation and laser transmission, the system eliminates redundant components that would increase weight and bulk. This integration enables portable deployment while maintaining distance measurement precision.
3Adaptability or versatility
If multiple separate optical channels are used, then comprehensive observation and ranging functions are achieved, but system complexity increases
Solution Approach 1:
The patent implements a universal optical channel that performs multiple functions: receiving observation radiation, transmitting laser radiation to the target, and collecting reflected laser radiation for distance measurement. The single optical element (beam splitter) enables this multi-functionality by directing different wavelengths or directions of light through appropriate pathways, eliminating the need for separate dedicated channels for each function and thereby reducing system complexity.
