Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If additional heat dissipation components are added to the wireless communication device, then heat dissipation performance is improved, but device size increases
Solution Approach 1:
The shield case is designed to serve dual functions: providing electromagnetic shielding for the communication module and acting as a heat dissipation component. By merging these two functions into a single structure, the patent eliminates the need for separate heat dissipation components, thereby improving heat dissipation performance without increasing device size.
Solution Approach 2:
The shield case is transformed into a multi-functional component that simultaneously performs electromagnetic shielding and heat dissipation. This universal design allows the same structure to address multiple technical requirements (shielding and thermal management), resolving the contradiction between heat dissipation performance and device size.
2Temperature
If heat dissipation components are added after functional component arrangement, then heat dissipation is addressed, but device miniaturization is hindered
Solution Approach 1:
The shield case is designed from the beginning to include heat dissipation functionality, rather than adding heat dissipation components later. By performing the heat dissipation design in the preliminary stage alongside the electromagnetic shielding function, the patent avoids increasing device complexity and enables miniaturization.
Solution Approach 2:
The patent combines the heat dissipation function with the shield case structure during the initial design phase, merging thermal management considerations with electromagnetic shielding design. This integrated approach prevents the need for additional components and maintains device simplicity.
