Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the second imaging system operates at a high frame rate continuously, then polyp detection accuracy is improved, but energy consumption increases and battery life is reduced
Solution Approach 1:
The patent applies dynamics by making the frame rate of the second imaging system adjustable rather than fixed. The system dynamically switches between a first frame rate (lower) and a second frame rate (higher) based on real-time polyp detection results from the first imaging system, allowing optimal energy consumption while maintaining detection accuracy when needed
Solution Approach 2:
The system performs preliminary detection using the first imaging system before activating the higher frame rate second imaging system. This preliminary action allows the system to prepare for high-energy operation only when polyps are detected, avoiding unnecessary energy consumption during normal surveillance
2Duration of action of moving object
If the second imaging system operates at a low frame rate to conserve energy, then battery life is extended, but polyp detection capability is reduced
Solution Approach 1:
The system dynamically adjusts the operating frame rate of the second imaging system based on detection needs. When no polyps are detected, it operates at a lower frame rate to extend battery life; when polyps are detected by the first imaging system, it switches to a higher frame rate to ensure accurate capture and analysis
3Loss of information
If both imaging systems operate simultaneously at high frame rates, then comprehensive image data is obtained, but energy consumption exceeds available power supply
Solution Approach 1:
The patent implements dynamic coordination between the two imaging systems. The first imaging system operates continuously at a baseline frame rate for surveillance, while the second imaging system's frame rate is dynamically adjusted based on detection events, ensuring comprehensive data collection without exceeding power supply limits
Solution Approach 2:
The system uses periodic detection cycles where the first imaging system continuously monitors and triggers the second imaging system only when polyps are detected. This periodic activation pattern ensures complete image data is obtained when needed while maintaining average power consumption within available supply limits
