Pressure-Activated Sealing Element for Large Gap Tightness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sealing elements fail to effectively seal large gaps under high-pressure conditions, leading to leakage and increased costs in electrolysis systems due to inefficiencies and competitive pressures.
Innovation Solution
A sealing element with orthogonal first and second portions, where the second portion presses onto a gap under ambient pressure, enhancing sealing performance by increasing contact area and pressure, allowing sealing of gaps up to 0.3 times the clearance height.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional sealing elements are used, then the structure is simple, but the sealing performance under high pressure is insufficient and leakage occurs
Solution Approach 1:
The sealing element is divided into two distinct portions: a first portion configured to dispose the sealing element in a clearance, and a second portion configured to press onto the gap. This segmentation allows each portion to perform its specific function optimally - the first portion provides structural support and positioning, while the second portion provides the sealing action under pressure, thereby resolving the contradiction between simple structure and reliable sealing performance.
Solution Approach 2:
The patent introduces a dimensional aspect by specifying that a first side of the first portion is disposed substantially orthogonal to a second side of the second portion. This orthogonal arrangement creates a three-dimensional configuration that allows the sealing element to effectively engage with gaps up to 0.3 times the clearance height, transforming a simple linear sealing approach into a multi-dimensional solution that maintains reliability without excessive complexity.
2Reliability
If sealing elements are designed for high-pressure conditions, then leakage is prevented, but the structural complexity increases
Solution Approach 1:
The second portion of the sealing element is designed to automatically press onto the gap when increased ambient pressure acts on it. This self-actuating mechanism eliminates the need for additional actuators, springs, or complex control systems to maintain sealing under pressure. The pressure differential itself becomes the actuating force, allowing the sealing element to self-adjust and maintain tightness without increasing overall device complexity.
3Reliability
If the sealing element presses onto large gaps, then sealing effectiveness improves, but the contact area requirements increase structural complexity
Solution Approach 1:
The patent applies local quality by concentrating the sealing function specifically in the second portion of the sealing element, which is designed to press onto the gap. The first portion provides general structural support and positioning in the clearance, while the second portion locally concentrates the sealing action. This localized approach allows effective sealing of large gaps without requiring the entire sealing element to have increased contact area, thereby maintaining structural simplicity.

AI summary
A sealing element for a high-pressure connection, including a first portion and a second portion. The first portion is configured to dispose the sealing element in a clearance. A first side of the first portion is disposed so as to be substantially orthogonal to a second side of the second portion. The second portion has a third side, and the second portion is configured to press the third side onto a gap to be sealed when an increased ambient pressure acts on the second side.
