Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If photoresistor is used for light detection, then the circuit can detect light conditions, but the detection accuracy is low and cannot distinguish between different light intensities and ultraviolet rays
Solution Approach 1:
The patent replaces the traditional photoresistor-based mechanical/electrical detection system with an optical detection system using a camera to capture images. The camera captures RGB images of the battery pack, and light intensity is calculated by analyzing the average brightness of pixels in the image, achieving more accurate and versatile light condition detection that can distinguish between different light intensities and ultraviolet rays.
Solution Approach 2:
The patent changes the detection parameter from simple resistance-based photoresistor output to multi-channel RGB color values from camera images. By calculating the average brightness from R, G, and B channel values, the system achieves more precise light intensity measurement and better adaptability for energy storage control under different lighting conditions.
2Adaptability or versatility
If traditional control methods are used without real-time lighting detection, then the control system is simpler, but the automatic adaptability and power regulation accuracy are low
Solution Approach 1:
The system performs self-service by automatically capturing images of the battery pack with a camera, calculating light intensity from the image data, and using this information to automatically adjust power supply regulation and energy storage control. This eliminates the need for manual intervention and achieves high automatic adaptability while the added complexity is minimal compared to the performance improvement.
3Adaptability or versatility
If multiple battery types are connected in parallel, then the system can handle different battery characteristics, but the control complexity increases
Solution Approach 1:
The patent implements a universal control approach where a single control circuit uses camera-based light intensity detection to manage multiple different battery types connected in parallel. The system captures images, calculates light intensity, and applies unified control strategies that adapt to different battery characteristics, achieving multi-functionality without requiring separate control circuits for each battery type.
