Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the electronic device uses conventional power sources continuously, then the display and front light module can operate without interruption, but the power consumption increases and energy efficiency decreases
Solution Approach 1:
The solar cell module performs preliminary energy accumulation during daytime by converting sunlight into electrical energy and storing it in the storage battery. This preliminary action ensures that sufficient energy is available for nighttime operation, eliminating the need for continuous power consumption and enabling the device to operate without interruption throughout the day-night cycle
Solution Approach 2:
The electronic device serves itself by using the solar cell module to generate its own electrical energy from ambient sunlight. The generated energy is stored in the storage battery and used to power the display and front light module, creating a self-sustaining energy system that reduces dependence on external power sources and lowers overall power consumption
2Productivity
If the solar cell module is added to harvest ambient light, then energy efficiency improves and charging frequency reduces, but the device structure becomes more complex
Solution Approach 1:
The solar cell module is integrated with the front light module structure, where the solar cell module serves dual purposes: generating electrical energy during the day and potentially serving as part of the lighting assembly. This merging of functions reduces the need for separate components and minimizes structural complexity while maintaining energy generation capability
Solution Approach 2:
The solar cell module performs multiple functions within the electronic device: it acts as both an energy generation source and a structural component integrated with the front light assembly. This multi-functionality reduces the overall component count and simplifies the device structure while improving energy efficiency and reducing charging frequency
