Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If photovoltaic cells are integrated into sunshade panels to enable energy harvesting, then the system can power display functions, but the system may drain power supply during periods of low sunlight
Solution Approach 1:
The system performs preliminary energy harvesting during daytime when sunlight is available, storing energy in capacitors before the display needs to operate. This allows the display to function during evening or night periods without external power, resolving the contradiction between display adaptability and power reliability.
Solution Approach 2:
Energy storage capacitors are introduced as intermediary components between the photovoltaic cells and the display system. These capacitors buffer the energy flow, accumulating energy during high production periods and releasing it during high consumption periods, thus decoupling the reliability of power supply from the adaptability of display operation.
2Use of energy by moving object
If panels are made rotatable to optimize energy capture, then photovoltaic efficiency is improved, but device complexity increases
Solution Approach 1:
The sunshade panels are designed with rotatable joints that allow them to dynamically adjust their orientation toward the sun. This dynamic positioning maximizes the angle of incidence for sunlight on photovoltaic cells throughout the day, significantly improving energy capture efficiency while adding only minimal mechanical complexity through simple rotational degrees of freedom.
