Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If light emission conditions are changed, then adaptability to varying environments is improved, but response time increases
Solution Approach 1:
The distance measuring sensor autonomously controls the lighting apparatus's light emission conditions based on detection results from its own pixels, eliminating the need for external host control and reducing response delay. The sensor self-adjusts light emission intensity and other parameters according to actual measurement needs.
Solution Approach 2:
The system implements a feedback mechanism where detection results from the pixel array are used to control subsequent light emission conditions. The control section adjusts light emission parameters based on feedback from the detection section, enabling adaptive response to varying environments.
2Measurement precision
If light emission intensity is increased, then measurement precision is improved, but energy consumption increases
Solution Approach 1:
The light emission intensity is dynamically adjusted based on detection results rather than maintaining a fixed high intensity. The control section varies light emission parameters in real-time according to actual measurement requirements, achieving high precision only when necessary.
Solution Approach 2:
The system changes light emission parameters (intensity, duration, modulation frequency) based on detection feedback. By adjusting these parameters dynamically, the system achieves high measurement precision when needed while reducing energy consumption during normal operation.
