Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional fixing means are used for the liquid accumulator, then the structure can be stabilized, but the process becomes complicated and manufacturing cost increases
Solution Approach 1:
The extending portion of the first suction cup is integrated directly into the cup structure, eliminating the need for separate fixing components. This merging of the support function into the existing structure simplifies the overall design while maintaining stability, directly resolving the contradiction between reliability and device complexity.
Solution Approach 2:
The extending portion serves multiple functions: it provides structural support for the liquid accumulator, facilitates welding connection, and maintains spatial relationships between components. This multi-functionality reduces the need for additional specialized fixing components, thereby simplifying the fixing process while ensuring stability.
2Manufacturing precision
If traditional welding processes are used, then the suction cups can be connected, but the welding process affects other parts and reduces welding quality
Solution Approach 1:
The extending portion is designed to extend into the cavity of the second suction cup, effectively isolating the welding zone. This extraction of the welding area from the main body structures prevents heat and stress from affecting other critical parts, thereby improving welding quality while minimizing harmful effects on surrounding components.
Solution Approach 2:
The welding surfaces are specifically positioned on the extending portion and outer surface of the second suction cup, creating a localized welding zone. This local quality approach ensures that welding operations are confined to specific areas, protecting other parts from thermal damage and maintaining overall component integrity while achieving high welding quality.
3Reliability
If complex fixing processes are used, then the liquid accumulator can be secured, but manufacturing cost increases
Solution Approach 1:
The first suction cup is segmented into a body portion and an extending portion, with the extending portion serving as an integrated support structure. This segmentation allows the support function to be achieved through the basic cup geometry itself, eliminating the need for additional fixing components and reducing manufacturing complexity and cost while maintaining reliable securing of the liquid accumulator.
