Pneumatic Shuttle Valve With Integrated Lip Seal for Leak Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pneumatic valves for vehicles face issues with leakage due to improperly assembled o-rings, leading to unpredictable air flow and difficult assembly detection, which are not effectively addressed by prior art solutions.
Innovation Solution
The integration of a radial lip seal with the shuttle member, forming a one-piece component that provides sealing, eliminating the need for separate o-rings and ensuring proper assembly, thus reducing leakage risks and enhancing assembly efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate o-rings are used for sealing the shuttle member in the cylinder, then the sealing function can be provided, but the assembly complexity increases and leakage risk increases due to improper assembly
Solution Approach 1:
The sealing function is integrated directly into the shuttle member by forming a sealing surface on its outer circumference, eliminating the need for separate o-rings. This merging of the sealing function into the main component simplifies assembly and reduces leakage risks associated with separate sealing elements.
2Reliability
If separate o-rings are used for sealing, then sealing function is provided, but the manufacturing cost increases and assembly detection becomes difficult
Solution Approach 1:
The sealing surface is formed as an integral part of the shuttle member during its manufacturing process, eliminating the need for separate o-ring components and their associated assembly steps. This integration reduces manufacturing complexity and enables easier quality detection.
3Reliability
If multiple separate components (shuttle member and o-rings) are used, then sealing function is achieved, but the number of components increases leading to higher assembly time
Solution Approach 1:
The sealing function is combined with the shuttle member into a single integrated component. This reduces the total number of parts that need to be assembled, thereby increasing assembly productivity while maintaining reliable sealing through the integrally formed sealing surface.
