Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate components are used for the check valve element, then reliable locking and structural stability are achieved, but manufacturing cost increases and assembly complexity increases
Solution Approach 1:
The patent combines the retaining ring and latching body into a single integrally formed component. The retaining ring encompasses the valve body while the latching body with detent projection extends from the retaining ring to engage with the detent receptacle. This merging eliminates the need for separate retaining and latching components, reducing part count while maintaining reliable locking through the integrated structure.
2Stability of the object's composition
If multiple separate components are used for the check valve element, then structural stability is achieved, but manufacturing cost increases
Solution Approach 1:
The retaining ring and latching body are formed as a single integral component, reducing the number of parts that need to be manufactured, stored, and assembled. This integration simplifies manufacturing processes and reduces costs while the integral formation ensures structural stability through continuous material flow between functional elements.
Solution Approach 2:
The integrally formed retaining ring and latching body perform multiple functions simultaneously: the retaining ring provides mechanical retention of the valve body, while the integrated latching body provides secure locking through the detent mechanism. This multi-functionality in a single component reduces overall system complexity and manufacturing cost.
3Reliability
If complex assembly structures are used, then reliable locking is achieved, but assembly ease decreases
Solution Approach 1:
By integrating the retaining ring and latching body into a single component, the patent reduces the number of assembly steps. The single component can be installed as one unit, eliminating the need to separately assemble retaining rings and latching mechanisms, thereby improving assembly ease while maintaining locking reliability through the integrated design.
