Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If traditional photovoltaic systems are used, then visible light can be converted to electric power, but 50% of solar energy (infrared heat) is wasted
Solution Approach 1:
The patent combines photovoltaic cells with photothermal collectors into a single integrated system. The photovoltaic cells convert visible light to electricity while the photothermal collectors absorb infrared radiation to heat working fluid, enabling simultaneous conversion of both visible and invisible solar energy components through merged functional components.
Solution Approach 2:
The patent creates a multi-functional system that performs both photovoltaic electricity generation and photothermal heating simultaneously. The same solar collector structure serves dual purposes: generating electricity through photovoltaic cells and producing thermal energy through photothermal absorption, making the system universally applicable for both power and heat needs.
2Loss of energy
If thermal systems are used, then infrared heat energy can be converted to electric power, but visible light energy is abandoned
Solution Approach 1:
The patent merges photothermal collectors with photovoltaic cells in an integrated architecture. The photothermal portion captures infrared radiation to generate heat for thermal power conversion, while the photovoltaic portion simultaneously converts visible light to electricity, ensuring both spectral regions are utilized through combined components.
Solution Approach 2:
The system achieves multi-functionality by enabling both thermal energy conversion and electrical energy generation from the same solar input. The integrated design allows the system to convert invisible infrared energy to heat and visible light energy to electricity simultaneously, eliminating energy abandonment.
3Adaptability or versatility
If wind turbines are installed in areas with low wind resources, then power generation can be achieved, but efficiency is significantly reduced
Solution Approach 1:
The patent employs dynamic tracking systems that automatically adjust the orientation of photovoltaic panels and photothermal collectors to follow the sun's movement throughout the day and year. This dynamic positioning optimizes energy capture in different geographical locations regardless of wind conditions, adapting the system to various regional characteristics while maintaining high efficiency.
4Productivity
If automatic tracking systems are added to enhance energy capture, then power generation efficiency increases, but equipment cost and complexity increase
Solution Approach 1:
The patent implements automatic tracking mechanisms that dynamically adjust panel and collector orientations to follow solar movement. These tracking systems use sensors and actuators to continuously optimize the angle of incidence for maximum energy capture, significantly enhancing productivity while the added complexity is offset by the substantial efficiency gains.
Solution Approach 2:
The tracking system incorporates feedback mechanisms using light sensors and position detectors to monitor solar position and system orientation. This feedback loop enables automatic adjustment of tracking angles to maintain optimal energy capture conditions, improving productivity through intelligent control while managing complexity through automated feedback-based operation.
