Pneumatic Valve Venting Guide Support Against Tilt and Leaks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pneumatic valves used in vehicles, particularly for brake systems, are prone to damage due to excessive forces exerted during assembly and operation, leading to tilting of the venting guide and potential leaks or water ingress.
Innovation Solution
The pneumatic valve incorporates a support projection on the venting guide that abuts a contact region on the housing, preventing excessive tilting and transferring forces to the housing, thereby reducing the risk of damage to the connection elements and preventing leaks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the venting guide is connected to the attachment portion using connection elements, then the venting guide can be engaged with the housing, but excessive forces during assembly and operation cause tilting and damage to the connection elements
Solution Approach 1:
The support projection is positioned adjacent to a contact region of the housing and configured to abut the contact region to prevent tilting of the venting guide relative to the housing. This preemptive support structure cushions against excessive forces before they can damage the connection elements, thereby resolving the contradiction between reliability and connection strength.
2Ease of operation
If the venting guide is positioned to allow flexibility during assembly, then assembly is easier, but the venting guide becomes prone to tilting and damage under operational forces
Solution Approach 1:
The support projection allows for controlled movement during assembly by abutting the contact region, providing dynamic adjustment capability. During operation, the same support projection prevents excessive tilting, thus maintaining reliability. This dynamic behavior resolves the contradiction between assembly ease and operational stability.
