Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If electric power consumption reducing processing is executed, then battery life is extended and internal temperature rise is reduced, but image quality deteriorates
Solution Approach 1:
The system dynamically switches between power-saving mode and high-image-quality mode based on detected start information. The processor adjusts its operation state in real-time: when start information is detected, it transitions to high-image-quality mode to capture clear images of important scenes; when no start information is present, it operates in power-saving mode to extend battery life. This dynamic adaptation resolves the contradiction by making image quality adjustable according to actual needs.
Solution Approach 2:
The system changes processing parameters based on operational state. When power-saving processing is active, the processor uses lower computation resources and reduced processing power. Upon detecting start information, it switches to high-image-quality processing with increased computational resources and higher processing power to ensure diagnostic accuracy. This parameter adjustment allows the system to optimize between battery consumption and image quality depending on the situation.
2Reliability
If compression ratio of image data is increased to prevent wireless communication blackout, then power consumption is reduced and communication reliability is improved, but image quality deteriorates
Solution Approach 1:
The compression ratio is dynamically adjusted based on the presence of start information. During normal operation, a higher compression ratio is applied to reduce data transmission volume and power consumption while maintaining communication reliability. When start information is detected, the system switches to a lower compression ratio to preserve image quality for important diagnostic scenes. This dynamic adjustment resolves the contradiction between communication reliability and image quality.
Solution Approach 2:
The image data compression parameter is changed according to operational state. In power-saving mode, aggressive compression is applied to minimize wireless data transmission and reduce power consumption. Upon detecting start information, the compression parameter is adjusted to maintain higher image quality for critical scenes. This parameter change strategy ensures that communication reliability is maintained through compression while image quality is preserved when diagnostically important.
3Use of energy by moving object
If illumination light amount is decreased to reduce power consumption, then power consumption is reduced, but image quality and brightness deteriorate
Solution Approach 1:
The illumination light amount is dynamically controlled based on detected start information. During power-saving operation, the illumination intensity is reduced to minimize power consumption from the light source. When start information is detected, the system increases illumination intensity to ensure adequate lighting for high-quality image capture of important scenes. This dynamic control resolves the contradiction between power consumption and image quality by adjusting illumination according to diagnostic needs.
Solution Approach 2:
The illumination parameter is adjusted based on operational state. In power-saving mode, the illumination light amount is set to a lower level to reduce energy consumption from the illumination element. Upon detecting start information, the illumination parameter is changed to a higher level to ensure sufficient lighting for capturing diagnostic images with high quality. This parameter adjustment resolves the trade-off between power consumption and image quality.
