Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the self-light-emitting pointing element adjusts light emission intensity based on received signal light intensity, then power consumption is reduced, but the light emission intensity cannot be optimized for actual detection conditions
Solution Approach 1:
The detection device measures the actual light intensity received from the pointing element and feeds back this information to adjust the light emission intensity. This closed-loop feedback mechanism ensures that the pointing element emits sufficient light for accurate detection while minimizing power consumption by adjusting intensity based on real detection conditions rather than using fixed or signal-light-based adjustment methods
Solution Approach 2:
The system allows the detection device to automatically determine and communicate the optimal light emission intensity to the pointing element based on detection requirements. The pointing element then self-adjusts its light emission according to the received control information, enabling autonomous optimization of power consumption and detection accuracy without manual intervention
2Reliability
If fixed light emission intensity is used, then detection accuracy is maintained, but power consumption increases
Solution Approach 1:
The light emission intensity is changed from a fixed parameter to a dynamic parameter that adapts to different detection conditions. The detection device calculates appropriate light emission intensities based on factors such as distance to the pointing element and detection requirements, then communicates these dynamic adjustment values to the pointing element, which adjusts its emission accordingly to maintain detection accuracy while optimizing power consumption
3Measurement precision
If high light emission intensity is used, then detection accuracy is improved, but power consumption increases
Solution Approach 1:
The system dynamically changes the light emission intensity parameter based on actual detection conditions. Rather than using high fixed intensity, the detection device calculates the optimal intensity level required for accurate detection at the current distance and environmental conditions, then adjusts the pointing element's emission parameter accordingly. This parameter adaptation maintains detection precision while minimizing power consumption by using only the necessary light intensity
