Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a smaller battery size is used, then the device becomes more compact and wearable, but the power capacity is reduced
Solution Approach 1:
The patent combines multiple power sources (battery and optical photoelectric conversion unit) into a hybrid power system. The optical photoelectric conversion unit captures ambient light to generate electrical power, which supplements or replaces battery power, thereby maintaining high power capacity while using a smaller battery.
Solution Approach 2:
The optical photoelectric conversion unit serves dual purposes: it generates electrical power from ambient light and can be integrated into the display module structure. This multi-functional approach allows the system to reduce battery size while maintaining adequate power supply through environmental energy harvesting.
2Device complexity
If traditional battery connections are used, then the structure is simple, but connection reliability deteriorates over time
Solution Approach 1:
The patent integrates the optical photoelectric conversion unit directly into the display module, merging the power generation function with the existing display structure. This integration eliminates separate connectors and wiring between the battery and display module, reducing connection points that could fail over time.
