Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If thin-type aluminum sheets are used to form the heat dissipating core, then heat dissipating effect is improved, but rigidity is insufficient and the sheets are easily bent and deformed
Solution Approach 1:
The patent uses composite materials by combining aluminum sheets with plastic materials to form an integrated heat dissipating core. The aluminum sheets provide thermal conductivity while the plastic material provides structural rigidity and support, resolving the contradiction between heat dissipating effect and rigidity.
2Temperature
If thin-type aluminum sheets are used to form the heat dissipating core, then heat dissipating effect is improved, but assembly complexity increases and quality stability decreases
Solution Approach 1:
The patent merges the aluminum sheets and plastic support structure into a single integrated heat dissipating core through injection molding. This combining of previously separate components (aluminum sheets, support structures, and fastening elements) into one molded part dramatically simplifies assembly and improves quality stability while maintaining the thin-type aluminum sheet configuration for effective heat dissipation.
3Reliability
If conventional heat exchanging module assembly process is used, then heat exchanging function is achieved, but assembly time is long and manufacturing cost is high
Solution Approach 1:
The patent combines multiple separate components (heat dissipating aluminum sheets, support structures, fastening elements, and separation elements) into a single integrated heat dissipating core through injection molding. This merging of components reduces the number of assembly steps from multiple separate operations to a single molded part installation, dramatically reducing assembly time and manufacturing cost while maintaining effective heat exchanging function.
4Reliability
If conventional heat exchanging module assembly process is used, then heat exchanging function is achieved, but manufacturing cost is high
Solution Approach 1:
The patent merges multiple discrete components into a single integrated heat dissipating core manufactured through injection molding. This consolidation eliminates the need for separate manufacturing and assembly processes for aluminum sheets, support structures, and fastening elements, thereby reducing manufacturing cost while maintaining the heat exchanging function.
Solution Approach 2:
The patent changes the manufacturing parameter from traditional multi-step assembly processes to a single injection molding process. This parameter change in the manufacturing method enables mass production of the integrated heat dissipating core at lower cost while ensuring consistent quality and functionality.
