Vehicle Pressure Relief Assembly Liquid-Diverting Cover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pressure relief devices in vehicles allow water to infiltrate into the interior cabin, compromising their effectiveness in maintaining a dry environment while allowing airflow, due to design limitations that either lead to leaks or block airflow.
Innovation Solution
A pressure relief assembly featuring a liquid-diverting cover with angled vanes that divert water into a drainage trough, while maintaining airflow passages to prevent water ingress and ensure efficient pressure relief.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a separate water trough is secured to the rear of the pressure relief device, then water infiltration is reduced, but the trough may be susceptible to leaks when water is collected and may not be tall enough to block all water
Solution Approach 1:
The liquid-diverting cover is segmented into multiple liquid diversion vanes that work together to create effective water blocking. Each vane is positioned to divert water in a specific direction, and collectively they form a comprehensive drainage system that prevents water accumulation and infiltration while maintaining reliability
Solution Approach 2:
The liquid diversion vanes are positioned at specific angles and heights to create a three-dimensional water diversion path. By extending the vanes to appropriate heights and angling them correctly, the system blocks water infiltration in multiple directions simultaneously while maintaining airflow passages
2Object-affected harmful factors
If a shield having a trough is clipped onto the rear of the pressure relief device to block water at higher levels, then water infiltration is prevented, but the shield blocks airflow thereby reducing the effectiveness of the pressure relief device
Solution Approach 1:
The liquid-diverting cover is divided into multiple separate liquid diversion vanes rather than a single continuous shield. This segmentation allows water to be diverted by individual vanes while leaving gaps between them for airflow passages, thus preventing water infiltration without blocking airflow
Solution Approach 2:
Different regions of the liquid-diverting cover have different functions: the liquid diversion vanes are positioned and angled to block and divert water, while specific areas between and around the vanes are designed as airflow passages. This local differentiation allows simultaneous water protection and airflow maintenance
Applied Scientific Principles
