Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If a solar cell module is added to a display for photon-electric conversion, then the display can generate renewable energy, but the thickness of the display increases substantially
Solution Approach 1:
The patent merges the solar cell module with the polarizer into a single integrated component. The polarizer is constructed with transparent conductive oxide layers and metal electrode patterns that simultaneously perform optical polarization and photon-electric conversion functions, eliminating the need for a separate solar cell module and reducing display thickness
Solution Approach 2:
The polarizer is designed to serve multiple functions: it polarizes incident light for display operation and simultaneously converts photon energy to electrical energy for powering the display. This multi-functional design allows one component to replace what would traditionally require separate elements
2Use of energy by moving object
If a separate solar cell module is placed under the liquid crystal panel, then photon-electric conversion is achieved, but the device structure becomes more complex
Solution Approach 1:
The solar cell module is merged with the polarizer structure, combining what were previously separate components into one integrated unit. The transparent conductive oxide layers and metal electrodes form both the polarizer functional layers and the photon-electric conversion elements, simplifying the overall device structure
3Use of energy by moving object
If the polarizer absorbs all incident light for photon-electric conversion, then energy generation is maximized, but no light passes through for display illumination
Solution Approach 1:
The polarizer structure is designed with spatially differentiated properties: transparent conductive oxide layers with specific orientation allow polarized light to pass through while metal electrode patterns and dye molecules selectively absorb photons for energy conversion. This local differentiation of optical properties enables simultaneous light transmission and energy absorption
Solution Approach 2:
The patent utilizes the polarization state of light as a parameter to differentiate between light that should pass through and light that should be absorbed. By aligning the transparent conductive oxide layers and dye molecules with specific orientations, the system allows polarized light to transmit while absorbing orthogonally polarized components for energy conversion
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This integration reduces the display's thickness and enhances the utilization of incident light by enabling simultaneous photon-electric conversion and optical polarization, increasing the efficiency of light usage without adding bulk.
Implementation Method 1
The light-polarized dye added into the photon-electric conversion element absorbs photon energy of an incident light, which has a direction of vibration parallel to absorption axis of the light-polarized dye, for photon-electric conversion and providing power to the display
Implementation Method 2
the second polarizer can perform photon-electric conversion and optical polarization simultaneously because the second polarizer plays both of the roles of the photon-electric conversion element (solar cell) and polarizer simultaneously
