Gasket With Interconnected Longitudinal And Transverse Ribs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gaskets fail to effectively prevent drop-out and meandering, allow medium to enter the mounting groove, and maintain sealing ability when thermal expansion differences occur between members.
Innovation Solution
A gasket with a combination of longitudinal and transverse ribs, where the transverse rib protrudes equally or more than the longitudinal rib, interconnected to cross each other, providing stable contact and preventing leaning and meandering, while allowing elastic deformation to maintain sealing despite thermal expansion differences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If contact area to the side wall is small, then the gasket can be easily fitted, but the gasket fits in a meandering manner
Solution Approach 1:
The continuous side surface is segmented into multiple discrete protrusions, providing localized contact points that guide the gasket into proper orientation while maintaining overall fitting ease
Solution Approach 2:
The protrusions act as intermediary elements between the gasket and mounting groove, providing discrete contact points that guide alignment and prevent meandering during the fitting process
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 ensures drop-out prevention, prevents medium entry, and maintains sealing ability even with thermal expansion differences, ensuring reliable sealing and preventing deterioration of the gasket.
Implementation Method 1
a gasket with variable protruded portions only on one side of the gasket

AI summary
A gasket for sealing a space between a first member and a second member fastened by a fastening member so as to face each other, the gasket being fitted in an annular mounting groove formed on one of facing surfaces of the first member and the second member. The gasket is provided with an annular gasket body formed along the mounting groove; a plurality of longitudinal ribs, made up of protruding bodies, provided on a side surface of the gasket body facing a side wall of the mounting groove, the longitudinal rib protruding along height direction corresponding to depth direction of the mounting groove of the gasket body and protruding at intervals in circumferential direction of the gasket body; and a transverse rib provided on the side surface, the transverse rib being made up of a protruding body continuously protruding over the entire circumference of the gasket body. The protruding height of the transverse rib from the side surface is equal to or greater than protruding height of the longitudinal rib from the side surface and the transverse rib and the longitudinal rib are interconnected so as to cross each other.
