Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If transparent material is applied on substrate or colored material with drilled hole is used to improve light transmittance in component region, then light transmittance is improved, but process risks and structural disadvantages occur
Solution Approach 1:
The patent applies electrochromic material to the substrate, which changes its optical properties (transmittance) by changing the electrical parameter (applying voltage). This allows dynamic control of light transmittance without physical modifications like drilling holes, resolving the contradiction between improving light transmittance and avoiding process risks
Solution Approach 2:
The patent replaces mechanical/physical modification methods (drilling holes, applying transparent materials) with an electrical control mechanism (electrochromic effect). By applying voltage to the electrochromic substrate, transmittance is controlled electrically rather than through mechanical structural changes, eliminating process risks associated with drilling and material application
2Illumination intensity
If transparent material or drilled hole is used to improve light transmittance, then light transmittance is improved, but structural disadvantages occur
Solution Approach 1:
The electrochromic substrate changes its optical parameter (transmittance) through electrical control rather than structural modification. The substrate maintains its complete, intact structure while dynamically adjusting light transmission by changing the electrical state of the electrochromic material, thus improving light transmittance without compromising structural stability
Solution Approach 2:
The patent replaces mechanical structural modifications (drilled holes, material layers) with an electrical control system. The substrate structure remains intact and stable, while light transmittance is controlled through the electrochromic effect activated by voltage application, avoiding structural disadvantages of physical modifications
