Integrated Pneumatic Valve Gasket With Built-In Check Valve
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pneumatic valve systems for commercial vehicles are complex and time-consuming to assemble, requiring multiple components for sealing and check valve functions, which increases costs and assembly time.
Innovation Solution
A single, integrated gasket device made of rubber or plastic with gasket chambers and a built-in check valve mechanism, utilizing spring parts to bias a body part against a valve seat, eliminating the need for additional elements and simplifying assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate components (gasket, check valve, spring, body part) are used to achieve sealing and check valve functions, then the reliability and functionality of the pneumatic valve system are improved, but the device complexity and assembly time increase
Solution Approach 1:
The patent combines the gasket, check valve body, spring, and sealing elements into a single integrated gasket device made of elastomeric material. This merging of multiple functional components into one piece reduces device complexity and assembly time while maintaining all necessary functions including sealing, check valve operation, and spring biasing
Solution Approach 2:
The integrated gasket device performs multiple functions simultaneously: it provides sealing between casing parts, houses the check valve mechanism, contains the spring for biasing, and enables air flow control. This multi-functionality eliminates the need for separate components while improving reliability
2Adaptability or versatility
If multiple separate components are used for sealing and check valve functions, then the functionality is comprehensive, but the assembly time and manufacturing costs increase
Solution Approach 1:
By integrating all check valve components (body, spring, sealing elements) into a single gasket device, the patent reduces the number of assembly steps from multiple component installations to a single gasket installation, significantly reducing assembly time while preserving full functional capability
Solution Approach 2:
The check valve components are pre-assembled and integrated into the gasket device during manufacturing, so that during system assembly, the entire functional unit is installed as one piece rather than requiring on-site assembly of multiple components
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The gasket device provides reliable sealing and check valve functions efficiently, reducing assembly time and costs by integrating both functions into a single part, allowing for easy adjustment of spring force and body part displacement to suit specific valve properties.
Implementation Method 1
at least one spring part for biasing said body part and connecting it to the gasket part
