Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple imaging/monitoring units are used to track monitoring targets, then tracking capability is improved, but detection accuracy of position remains low
Solution Approach 1:
A detection device is introduced as an intermediary component attached to the monitoring target. This detection device includes a light receiver that receives detection light from the monitoring device and a light emitter that emits light toward the monitoring device. The intermediary detection device enables bidirectional communication between the monitoring device and monitoring target, allowing for precise position detection through coordinated light reception and emission timing.
Solution Approach 2:
The system changes the timing parameters of light emission and reception to improve detection accuracy. The detection device is configured to receive detection light at specific timings and emit response light at predetermined intervals. By controlling the timing parameters of light interaction, the system achieves accurate position detection of monitoring targets while maintaining tracking capability.
2Measurement precision
If detection devices with light reception and emission functions are attached to monitoring targets, then detection accuracy is improved, but device complexity increases
Solution Approach 1:
The detection device merges multiple functions into a single integrated unit attached to the monitoring target. It combines the light receiver function (receiving detection light from the monitoring device) and the light emitter function (emitting response light back to the monitoring device) into one compact assembly. This merging reduces overall system complexity while achieving improved detection accuracy through coordinated light interaction.
3Ease of operation
If the monitoring device projects detection light and receives reflected light, then identification capability is improved, but measurement precision of positional relationship remains insufficient
Solution Approach 1:
The system implements a feedback mechanism where the detection device receives detection light from the monitoring device and emits response light back to the monitoring device at predetermined timings. This feedback loop enables the monitoring device to not only identify monitoring targets but also precisely determine their positions by measuring the timing and characteristics of the returned light signals, thereby achieving accurate positional relationship measurement.
