Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If light is emitted at constant irradiation energy for distance measurement, then the distance measurement operation is simple, but the accuracy of both distance measurement and subject recognition cannot be achieved simultaneously
Solution Approach 1:
The patent applies dynamics by making the irradiation energy of the light variable rather than constant. The light emission unit changes irradiation energy according to measurement distance, transforming a static system into a dynamic one that adapts to different measurement conditions, thereby resolving the contradiction between measurement accuracy and system simplicity.
Solution Approach 2:
The patent changes the parameter of irradiation energy based on measurement distance. By adjusting this physical parameter dynamically, the system achieves high accuracy in both distance measurement and subject recognition without requiring complex additional hardware, thus resolving the technical contradiction.
2Measurement precision
If light irradiation energy is increased for better distance measurement, then measurement range is extended, but subject recognition accuracy may deteriorate due to overexposure
Solution Approach 1:
The system dynamically adjusts irradiation energy levels based on measurement distance, allowing it to optimize for distance measurement when needed while preventing subject overexposure. This dynamic control resolves the contradiction between extending measurement range and maintaining subject recognition quality.
Solution Approach 2:
By changing the irradiation energy parameter according to distance conditions, the system achieves accurate distance measurement without compromising subject recognition. The parameter adjustment ensures that light intensity remains within optimal ranges for both measurement and imaging functions.
3Productivity
If recognition operation and distance measurement operation are performed simultaneously with constant light energy, then processing speed is maintained, but accuracy of both operations deteriorates
Solution Approach 1:
The patent implements dynamic irradiation energy adjustment that operates simultaneously with recognition processing. The system maintains high processing speed while achieving high accuracy in both operations through real-time energy modulation based on measurement distance, resolving the contradiction between speed and accuracy.
