Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a heating element is added to heat the fluid, then the cleaning performance is improved, but the fluid delivering efficiency deteriorates due to increased resistance
Solution Approach 1:
The flow guiding element is divided into multiple flow guiding pieces (e.g., three pieces) that are distributed around the annular portion. Each piece independently guides fluid flow, segmenting the heating and flow guidance functions to reduce overall resistance while maintaining heating effectiveness.
Solution Approach 2:
The flow guiding pieces have spiral curved surfaces instead of straight or angular structures. This spiral curvature guides fluid to flow in a rotational pattern, reducing turbulence and resistance caused by abrupt directional changes, thereby improving fluid delivering efficiency while the heating element maintains fluid temperature.
2Power
If the heating element heats the fluid, then the cleaning rate is improved, but the fluid flow rate decreases due to resistance
Solution Approach 1:
The spiral curved surfaces of the flow guiding pieces create a gradual rotational flow path that reduces fluid resistance and maintains higher flow rates, countering the flow reduction caused by heating element resistance.
Solution Approach 2:
The flow guiding pieces change the flow parameters by creating a spiral motion pattern, which alters the fluid dynamics to reduce resistance and maintain flow rate even when heating element resistance is present.
3Productivity
If flow guiding pieces are added to increase fluid flow rate, then the fluid delivering efficiency is improved, but the device complexity increases
Solution Approach 1:
The flow guiding pieces are integrated with the annular portion to form a unified flow guiding element, merging the flow guidance function with the existing pump structure rather than adding separate components, thereby reducing overall device complexity.
Solution Approach 2:
The flow guiding element serves multiple functions: it guides fluid flow, reduces resistance, and works in conjunction with the heating element. This multi-functionality eliminates the need for separate components, simplifying the overall pump structure while improving fluid delivering efficiency.
