Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If real-time calculation of optimal laser transmission and reception amplification factors is performed for accurate distance measurement, then measurement precision is improved, but loss of time increases
Solution Approach 1:
The patent applies preliminary action by pre-calculating and storing optimal laser transmission intensity and reception amplification factor combinations in a lookup table before actual detection operations. When an object needs to be detected, the system simply retrieves the appropriate configuration from the pre-prepared table based on object characteristics, eliminating the need for time-consuming real-time calculations while maintaining measurement precision.
2Adaptability or versatility
If dynamic changing of laser transmission intensity or reception amplification factor is performed to adapt to different objects, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent prepares multiple pre-optimized configuration combinations of laser transmission intensity and reception amplification factor in advance, stored in a lookup table. Each configuration is pre-calculated to be optimal for specific object types or detection scenarios. This allows the system to adapt to different objects by simply selecting from pre-prepared options rather than dynamically calculating optimal settings, thereby reducing control system complexity while maintaining high adaptability.
Solution Approach 2:
The patent changes the approach from dynamic parameter optimization to selecting from pre-defined parameter combinations. By storing multiple configurations with different laser transmission intensities and reception amplification factors in a lookup table, the system can adapt to various detection scenarios by retrieving appropriate parameter sets, simplifying the control logic while maintaining versatility.
