Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a metal case is used to provide structural strength and rigidity, then the structural strength and rigidity are improved, but heat from heat sources is quickly conducted to the case surface forming high-temperature hot spots that cause user discomfort
Solution Approach 1:
The inner side of the metal case is divided into multiple thermal insulation areas by concave channels. This segmentation prevents heat from spreading across the entire case surface, isolating heat sources from the outer surface and reducing hot spot formation while maintaining the overall structural integrity of the metal case.
Solution Approach 2:
A plastic cladding body is introduced as an intermediary layer between the metal case and the external environment. This plastic layer has lower thermal conductivity than metal, acting as a thermal barrier that reduces heat transmission to the case surface while preserving the metal case's structural strength.
2Loss of energy
If a metal case is used for heat dissipation, then heat is conducted quickly to the outside, but heat from one heat source is easily transmitted to other heat sources or electronic elements causing overheat and performance deterioration
Solution Approach 1:
The metal case inner side is segmented into multiple thermal insulation areas by concave channels, creating isolated thermal zones. Each heat source is contained within its own thermal zone, preventing heat transmission between adjacent heat sources and electronic elements while still allowing heat dissipation to the external environment through the metal case structure.
