Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single-piece insert design is used, then manufacturing is simpler, but the variety of flow channel cross-sectional shapes is limited
Solution Approach 1:
The insert is divided into a first insert part and a second insert part that can be assembled together. This segmentation allows each part to be manufactured with simpler geometry while achieving complex overall flow channel cross-sectional shapes when combined, thereby increasing design versatility without requiring each individual component to be highly complex
2Manufacturing precision
If complex geometries are achieved through manufacturing, then flow channel optimization is improved, but manufacturing cost and complexity increase
Solution Approach 1:
By dividing the insert into multiple parts, each part can be manufactured using simpler, more cost-effective processes while maintaining high geometric precision. The segmented design allows for optimized manufacturing of each component separately, reducing overall manufacturing complexity and cost while achieving the required flow channel geometry precision through the assembly of precisely formed parts
Solution Approach 2:
The invention utilizes parameters such as convex bulges and varying wall thicknesses in the insert parts to optimize flow channel geometry. These parameter variations are implemented in a way that achieves superior flow characteristics while remaining compatible with standard manufacturing processes, thereby maintaining ease of manufacture while improving manufacturing precision
3Ease of operation
If traditional single-piece inserts are used, then assembly is simpler, but assembly complexity of the overall fitting increases due to manufacturing constraints
Solution Approach 1:
The segmented insert design allows the first and second insert parts to be manufactured separately with optimized geometries that would be difficult or impossible to achieve with a single-piece design. This segmentation enables each part to be tailored for optimal flow characteristics while keeping individual component manufacturing simple, thereby reducing overall device complexity despite the multi-part assembly
