Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a water-resistant and dust-resistant enclosed chassis is used, then component protection is improved, but heat dissipation deteriorates
Solution Approach 1:
The patent introduces gap filler material as an intermediary substance between the heat sink and chassis interior surface. This material serves dual functions: it maintains the enclosed protective environment while providing a thermal conduction path for heat dissipation, thus resolving the contradiction between protection and heat management.
Solution Approach 2:
The patent changes the thermal conduction parameter by introducing a material with high thermal conductivity (the gap filler) into the enclosed space. This allows heat to conduct through the chassis wall without requiring openings, thereby maintaining both protection and effective heat transfer.
2Temperature
If additional heat sinks or modifications are made to improve heat dissipation, then heat dissipation is improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent enables the existing chassis to serve the dual purpose of both protection and heat dissipation. By applying gap filler material to the interior surface, the chassis itself becomes part of the thermal management system, eliminating the need for additional complex heat dissipation structures.
Solution Approach 2:
The patent merges the protective enclosure function with the heat dissipation function by integrating the gap filler material into the chassis structure. This combination allows a single component (the chassis with gap filler) to perform both protection and thermal management, reducing overall device complexity.
3Temperature
If additional heat sinks or modifications are made to improve heat dissipation, then heat dissipation is improved, but manufacturing cost and labor increase
Solution Approach 1:
The gap filler material is applied during the assembly process before final chassis closure, making the heat dissipation solution integrated into the manufacturing workflow. This preliminary action eliminates the need for post-assembly modifications and reduces labor requirements.
