Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If mechanical means are used to change the assembly's angle over the course of a day, then efficiency is improved, but maintenance costs and risk of damage increase significantly
Solution Approach 1:
The patent replaces mechanical angle-adjustment systems with an optical element that redirects light from various angles to the photovoltaic cell. This eliminates moving parts and mechanical maintenance while maintaining high efficiency throughout the day by optically concentrating sunlight onto the cell regardless of its fixed orientation.
Solution Approach 2:
The optical element serves multiple functions: it concentrates light onto the photovoltaic cell, redirects light from multiple incidence angles, and eliminates the need for mechanical adjustment mechanisms. This multi-functionality resolves the contradiction by achieving both high efficiency and reliability simultaneously.
2Quantity of substance
If a smaller photovoltaic cell area is used with light concentration, then material cost is reduced, but thermal stability becomes more challenging
Solution Approach 1:
The patent extracts the thermal management function as a separate component - a heat sink attached to the photovoltaic cell assembly. This dedicated thermal management system removes excess heat from the concentrated light energy, enabling the use of smaller, more cost-effective photovoltaic cells while maintaining thermal stability.
Solution Approach 2:
The heat sink acts as an intermediary between the photovoltaic cell and the environment, absorbing and dissipating thermal energy. This mediator enables the system to handle concentrated light energy without compromising the thermal stability of the reduced-size photovoltaic cell.
3Productivity
If perovskite materials are used to improve efficiency, then photovoltaic performance increases, but thermal sensitivity and stability decrease
Solution Approach 1:
The patent extracts the thermal management function from the photovoltaic cell itself and implements it as a separate heat sink component. This allows perovskite materials to be used for high efficiency while the heat sink independently handles thermal sensitivity, protecting the perovskite from excessive heat exposure.
Solution Approach 2:
The system creates a composite structure combining perovskite photovoltaic materials with thermal management components. This composite approach allows the perovskite to provide high efficiency while the integrated heat sink provides thermal stability, resolving the contradiction between performance and stability.
