Membrane Ventilation Component for Slant-Angle Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ventilation components are prone to breakage when inserted at a slant angle into the axis of a housing opening, as they lack effective design features to prevent deformation and damage during attachment.
Innovation Solution
A ventilation component with a ventilation path, a supporting portion, a gas-permeable membrane, a tubular protruding portion, and a sealing member, where the protruding portion is designed to contact the edge of the housing opening and satisfy specific geometric ratios to minimize deformation and breakage risks, including 2.5≤Gs/Gt≤5.0 and 1.0≤{(Gs−Gt)/2}/Lt≤3.0, ensuring secure attachment without parallel alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the ventilation component is inserted at a slant angle to the axis of the opening, then the ease of operation is improved, but the strength is worsened causing breakage
Solution Approach 1:
The patent applies beforehand cushioning by designing the protruding portion with specific geometric ratios (2.5≤Gs/Gt≤5.0 and 1.0≤{(Gs−Gt)/2}/Lt≤3.0) that preemptively reduce deformation and moment forces during slant-angle insertion. The supporting portion surrounding the ventilation path provides structural reinforcement before insertion occurs, preventing breakage during the insertion process.
2Strength
If the protruding portion is designed with larger dimensions to prevent breakage, then the strength is improved, but the device complexity increases
Solution Approach 1:
The patent applies parameter changes by establishing specific geometric ratio ranges (2.5≤Gs/Gt≤5.0 and 1.0≤{(Gs−Gt)/2}/Lt≤3.0) that optimize the balance between strength and simplicity. These parameter definitions allow the protruding portion to achieve adequate strength without excessive dimensional increases, maintaining design efficiency while preventing breakage during insertion.
