Engineering Contradiction Analysis
1Temperature
If multiple cut-outs are provided in the base body to enable heat dissipation, then heat dissipation efficiency is improved, but manufacturing cost and complexity increase
Solution Approach 1:
The base body is divided into multiple longitudinal segments separated by longitudinal grooves, creating a multi-faceted outer surface that enhances heat dissipation through increased surface area. This segmentation is achieved through a single extrusion process, avoiding the need for multiple cut-outs and complex manufacturing steps.
Solution Approach 2:
Instead of creating cut-outs that remove material from the base body, the invention adds dimensional complexity through longitudinal grooves that create a multi-faceted surface. This transforms the heat dissipation approach from volumetric (cut-outs) to surface-based (grooves), achieving better cooling without compromising structural integrity or increasing manufacturing complexity.
2Temperature
If multiple cut-outs are provided in the base body to enable heat dissipation, then heat dissipation efficiency is improved, but mechanical robustness deteriorates
Solution Approach 1:
The base body is divided into multiple longitudinal segments separated by longitudinal grooves, creating a multi-faceted outer surface that enhances heat dissipation through increased surface area. This segmentation is achieved through a single extrusion process, avoiding the need for multiple cut-outs and complex manufacturing steps.
Solution Approach 2:
The longitudinal grooves are positioned specifically to optimize heat dissipation while maintaining mechanical strength. The grooves create localized surface area increases without compromising the overall structural integrity of the base body, as the material between grooves remains continuous and load-bearing.
