Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a metallic reflective coating is used to reflect electromagnetic radiation, then the reflection efficiency is improved, but the electrical insulation is worsened due to current flow through the conductive coating
Solution Approach 1:
The patent applies composite materials by combining non-metallic reflective particles (such as titanium dioxide, zinc oxide, or barium sulfate) with a binder material to create a reflective coating that maintains electrical insulation while achieving the desired reflection efficiency. This composite structure allows the coating to reflect electromagnetic radiation effectively without conducting electrical current, thus resolving the contradiction between reflection efficiency and electrical insulation.
2Use of energy by moving object
If radiation is absorbed by the electronic component to improve optical interaction, then the optical efficiency is improved, but the heating is worsened leading to overheating and measurement interference
Solution Approach 1:
The patent converts the harmful effect of radiation absorption (heating) into a beneficial reflection mechanism. By using a non-metallic reflective coating, the component reflects incident electromagnetic radiation away from the functional body, preventing energy absorption and subsequent heating. This resolves the contradiction by transforming the potential harm of radiation interaction into a beneficial thermal management solution while maintaining optical efficiency through controlled reflection.
