Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If sealing rings are directly adhered to the planar surface of the assembly body, then the assembly process is simple, but misalignment occurs affecting sealing effect and blocking assembly holes
Solution Approach 1:
The assembly body surface is segmented into a planar region and a stepped region with different heights. The sealing ring is specifically positioned on the stepped region, which provides lateral support through the side wall. This segmentation allows the sealing ring to be accurately positioned without complex alignment procedures while maintaining assembly simplicity.
Solution Approach 2:
The stepped structure acts as an intermediary between the planar surface and the sealing ring. By providing a stepped region with vertical side walls, it mediates the positioning function, enabling the sealing ring to be laterally supported and accurately positioned without requiring complex alignment tools or procedures.
2Productivity
If sealing rings are directly adhered to the planar surface, then assembly steps are reduced, but misalignment blocks assembly holes and reduces product yield
Solution Approach 1:
The assembly body is divided into regions with different heights (planar region and stepped region). The sealing ring is positioned on the stepped region where the side wall provides lateral support. This segmentation ensures proper positioning that prevents misalignment and blocking of assembly holes, thereby maintaining sealing effectiveness without reducing assembly efficiency.
Solution Approach 2:
The stepped structure is pre-formed on the assembly body before the sealing ring is adhered. This preliminary action of creating the stepped region with vertical side walls provides built-in positioning features that guide the sealing ring into the correct position, preventing misalignment and ensuring sealing effectiveness before the actual assembly operation occurs.
3Device complexity
If sealing rings are adhered without positioning features, then the structure is simple, but accurate assembly becomes difficult
Solution Approach 1:
The assembly body surface is segmented into a planar region and a stepped region. The stepped region provides lateral support through its vertical side wall, creating a simple yet effective positioning feature. This segmentation enables accurate assembly without adding complex positioning mechanisms, maintaining structural simplicity while improving ease of operation.
Solution Approach 2:
The positioning function is achieved by transitioning from a two-dimensional planar surface to a three-dimensional stepped structure with vertical side walls. This dimensional change provides lateral support in the horizontal direction, enabling accurate positioning of the sealing ring without adding complex positioning features, thus maintaining structural simplicity while easing assembly.
