Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If non-metallic materials are used for chassis body, then cost and flexibility are reduced, but cooling efficiency and electromagnetic shielding deteriorate
Solution Approach 1:
The chassis is segmented into metallic and non-metallic portions, with the non-metallic portion containing molded-in channels for fluid flow. This segmentation allows the non-metallic material to provide cost and flexibility benefits while the molded channels maintain cooling efficiency by guiding fluid flow directly to heat-generating components.
Solution Approach 2:
The chassis uses composite construction combining metallic and non-metallic materials. The non-metallic portion incorporates electromagnetic shielding coatings and molded channels, creating a composite structure that provides cost reduction while maintaining cooling efficiency and electromagnetic shielding properties.
2Ease of manufacture
If non-metallic materials are used for chassis body, then cost and flexibility are reduced, but electromagnetic shielding deteriorates
Solution Approach 1:
The non-metallic chassis portion is combined with electromagnetic shielding coatings to create a composite structure. This allows the chassis to benefit from the cost and flexibility advantages of non-metallic materials while the shielding coating maintains electromagnetic protection.
Solution Approach 2:
Electromagnetic shielding coatings are applied to the non-metallic chassis portion to act as an intermediary that provides electromagnetic shielding protection. This mediator allows the use of cost-effective non-metallic materials while maintaining the required electromagnetic shielding performance.
3Temperature
If traditional cooling methods are used, then heat dissipation is maintained, but fan power consumption and space usage increase
Solution Approach 1:
The cooling system is segmented into multiple independent channels, each dedicated to specific heat-generating elements. This segmentation allows for targeted cooling that reduces the total power consumption of fans by efficiently directing fluid flow only where heat generation occurs, rather than using a single large cooling system.
Solution Approach 2:
The molded channels provide localized cooling paths that are specifically tailored to the heat generation patterns of different components. This local quality approach ensures that cooling resources are concentrated where needed, reducing overall fan power consumption while maintaining effective heat dissipation.
4Temperature
If traditional cooling methods are used, then heat dissipation is maintained, but space occupied by cooling components increases
Solution Approach 1:
The cooling channels are merged into the chassis body itself through molded-in construction. This integration eliminates the need for separate cooling ducts and components, reducing the space occupied by cooling system components while maintaining effective heat dissipation pathways.
Solution Approach 2:
The cooling channels are nested within the chassis structure, with channels molded into the non-metallic portion of the chassis body. This nesting approach allows the cooling system to occupy the same space as the chassis structure, minimizing the overall volume required for cooling components.

AI summary
There is provided a chassis for a computing system comprising a heat-generating element. The chassis comprises a body with at least a portion thereof made of a non-metallic material, namely a nonmetallic portion. For example, the non-metallic material can be a moldable plastic. There is provided a channel made in the non-metallic portion, the channel having a starting point close to a dedicated location for a fan, the channel having an ending point close to a dedicated portion for the heat-generating element, the channel shaped to guide fluid propelled at the starting point to the ending point. The channel can be a tunnel inside the body or a valley on the surface of the body, and confines fluid flow from the fan, guiding the fluid flow to the heat-generating element.
