Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple optical sensors operate simultaneously to capture optical data, then the system can gather comprehensive sensing information, but the sensing of one optical sensor interferes with the sensing of another optical sensor
Solution Approach 1:
The patent implements periodic action by dividing the sensing operation into distinct time intervals where different optical sensors operate alternately. The optical sensor captures optical data during first sensing time intervals while the TOF optical sensor captures data during second sensing time intervals, with these intervals arranged to prevent overlap. This periodic scheduling allows multiple sensors to function comprehensively without simultaneous interference, resolving the contradiction between comprehensive sensing capability and sensing accuracy.
Solution Approach 2:
The patent applies segmentation by dividing the time domain into separate sensing time intervals for different optical sensors. Instead of having all sensors operate simultaneously, the system segments the sensing process so that the optical sensor operates during first sensing time intervals and the TOF optical sensor operates during second sensing time intervals. This temporal segmentation eliminates mutual interference while preserving the comprehensive sensing capabilities of multiple sensors.
2Productivity
If optical sensors operate in overlapping time intervals to maximize data capture efficiency, then the system achieves high productivity, but interference between sensors degrades measurement precision
Solution Approach 1:
The system maintains high productivity by implementing periodic action with non-overlapping sensing time intervals. The optical sensor and TOF optical sensor operate in alternating periods, ensuring that data capture is continuous and efficient without simultaneous operation. This periodic scheduling prevents interference while maximizing the overall data capture efficiency of the multi-sensor system.
Solution Approach 2:
The patent applies dynamics by making the sensing operation time-dependent and adaptive. The system dynamically assigns different time intervals to different sensors based on their operational requirements, with the optical sensor active during first sensing time intervals and the TOF sensor active during second sensing time intervals. This dynamic time allocation optimizes both productivity and measurement precision by preventing interference while maintaining continuous sensing operations.
