Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If transmission signals are sent at regular intervals for continuous object detection, then detection coverage is improved, but signal interference from other radar or communication devices increases
Solution Approach 1:
The patent applies dynamics by making the transmission start point intervals variable rather than fixed. The radar apparatus dynamically adjusts the interval between transmission start points based on detected interference levels, transforming a static transmission pattern into an adaptive one that responds to environmental conditions, thereby reducing interference while maintaining detection reliability
Solution Approach 2:
The patent changes the time interval parameter between transmission start points to avoid interference. By modifying this temporal parameter dynamically, the system shifts transmission timing away from interfering signals from other radar or communication devices, resolving the contradiction between continuous detection and interference avoidance
2Reliability
If transmission power is increased to improve detection range, then detection capability is improved, but interference with other devices and virtual object misrecognition increases
Solution Approach 1:
The patent employs periodic action by transmitting signals at controlled, intermittent intervals rather than continuously. By regulating the periodic transmission start points, the system achieves adequate detection coverage while reducing overall interference signal strength and minimizing the risk of virtual object misrecognition that would result from continuous high-power transmission
3Measurement precision
If signal processing sensitivity is increased to detect distant objects, then detection range is improved, but misrecognition of virtual objects as real objects increases
Solution Approach 1:
The patent implements feedback by using the detected reflection signal characteristics to adjust subsequent transmission timing. The system monitors for signs of virtual objects and feeds this information back into the transmission control mechanism, adjusting transmission start point intervals to prevent further virtual object generation, thus resolving the contradiction between sensitivity and recognition accuracy
