Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If multiple welding procedures are performed on the liquid cooling manifold, then branch pipelines and fixing parts can be connected, but thermal deformation of the pipe wall occurs readily
Solution Approach 1:
The patent integrates the adapter functionality directly into the manifold body by forming fixing portions with threaded holes during the injection molding process. This merging of functions eliminates the need for separate adapter components and welding operations, thereby preventing thermal deformation while maintaining connection capability.
Solution Approach 2:
The patent replaces the welding process with a mechanical threading system. Instead of using heat-based welding to create connections, the invention uses pre-formed threaded holes in the fixing portions to mechanically secure branch pipelines and fixing parts, eliminating thermal deformation caused by welding.
2Strength
If adapters are welded on the pipe wall to provide sufficient screw hole depth, then branch pipelines can be fixed securely, but liquid leakage may occur due to poor welding
Solution Approach 1:
The adapter functionality is merged into the manifold body through integral forming. The fixing portions are created as part of the main manifold structure during injection molding, eliminating the need for separate welded adapter components and their associated sealing issues.
Solution Approach 2:
The welding-based connection system is replaced with a mechanical threading system. Threaded holes are formed directly in the manifold body, providing secure mechanical fastening without the sealing vulnerabilities inherent in welded joints.
3Adaptability or versatility
If multiple components including adapters are used in the assembly, then connection requirements can be met, but the structure becomes complicated with high costs and poor precision due to accumulated tolerance
Solution Approach 1:
The patent combines multiple functions (manifold body, adapter, and fixing mechanism) into a single integrated component. The fixing portions with threaded holes are formed as part of the manifold body during injection molding, eliminating the need for separate adapter components and reducing assembly complexity.
Solution Approach 2:
The manifold body is designed with multi-functionality, serving both as the fluid distribution component and as the mounting structure for branch pipelines and fixing parts. The fixing portions provide universal attachment capability directly on the manifold body, reducing the need for specialized adapter components.
