Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If heat dissipating holes are used for heat dissipation, then heat dissipation function is provided, but dust enters through the holes causing reduced service life
Solution Approach 1:
A dust-proof net is introduced as an intermediary component between the heat dissipating holes and the internal electrical components. The dust-proof net allows heat to pass through while blocking dust particles, thus resolving the contradiction between heat dissipation efficiency and protection against dust contamination.
Solution Approach 2:
The dust-proof net functions as a thin film structure that covers the heat dissipating holes. This thin film allows thermal energy to pass through while providing a physical barrier against dust, maintaining heat dissipation effectiveness while protecting internal components.
2Temperature
If conventional heat dissipating holes are used, then heat dissipation is provided, but heat dissipation efficiency is low and effect is poor
Solution Approach 1:
The invention merges multiple functions into the dust-proof net component: it serves as both a dust barrier and a heat dissipation facilitator. Additionally, the dust-proof nets are movably connected to allow adjustment, enabling optimization of heat dissipation pathways while maintaining dust protection.
Solution Approach 2:
The dust-proof nets are movably connected to the inner wall of the box body, allowing them to be adjusted or removed. This dynamic configuration enables optimization of heat dissipation efficiency by adjusting the net position or removing it when maximum heat dissipation is required, while still providing dust protection during normal operation.
