Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional solar panel structures are custom-made according to device shape and size, then power extraction reliability is improved, but design development time and manufacturing cost increase
Solution Approach 1:
The patent applies universality by designing a standardized solar panel structure where the coat with extraction wirings can be used across different electronic devices regardless of shape and size. The solar cell, electrodes, and coat assembly form a universal module that can be adapted to various device configurations, eliminating the need for custom-designed solar panel structures for each device type.
Solution Approach 2:
The patent segments the solar panel into distinct functional components: the solar cell with electrodes, the coat with extraction wirings, and the protective layers. This segmentation allows the extraction wiring structure to be independently designed and manufactured as a standardized component that can be universally applied to different devices, reducing design complexity and development time.
2Reliability
If conventional solar panel structures are custom-made according to device shape and size, then power extraction reliability is improved, but manufacturing cost increases
Solution Approach 1:
The patent applies universality by designing a standardized solar panel structure where the coat with extraction wirings can be used across different electronic devices regardless of shape and size. The solar cell, electrodes, and coat assembly form a universal module that can be adapted to various device configurations, eliminating the need for custom-designed solar panel structures for each device type.
Solution Approach 2:
The patent utilizes parameter changes by allowing the standardized solar panel structure to be scaled and configured with different dimensions, materials, and wiring arrangements to suit various device requirements. This enables cost-effective mass production of standardized components while maintaining adaptability through parameter adjustment rather than complete redesign.
3Adaptability or versatility
If extraction wirings are located on the coat surface, then power output flexibility is improved, but light incidence may be obstructed
Solution Approach 1:
The patent applies dimensionality change by positioning the extraction wirings on the surface of the coat in a configuration that utilizes the two-dimensional surface space without blocking the three-dimensional light path to the solar cell. The wirings are arranged to extract power flexibly while maintaining optical transparency, effectively separating the electrical function from the optical path.
Solution Approach 2:
The patent applies local quality by designing the coat with regions of different properties: areas with extraction wirings for electrical connection and areas without wirings for optimal light transmission. This localized differentiation allows the structure to simultaneously provide power extraction flexibility and maintain high light incidence efficiency at different locations on the solar panel.
