Hyperbaric Oxygen Chamber Gasket for Pressure-Stable Airtight Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hyperbaric oxygen chambers face issues with oxygen leakage through gaps in the opening and closing mechanisms, posing a risk of fire or explosion, and existing solutions are inadequate in maintaining airtightness.
Innovation Solution
A hyperbaric oxygen chamber equipped with a sealing gasket that surrounds a flange and features wings to maintain continuous contact with the door, ensuring airtightness by adapting to pressure changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional opening and closing mechanism is used, then the chamber can be opened and closed, but oxygen leakage occurs through gaps between components
Solution Approach 1:
A sealing gasket is introduced as an intermediary component between the door and chamber body to fill and seal gaps. The gasket includes a wing that actively engages with the door surface to prevent oxygen leakage through the interface between moving and stationary components.
Solution Approach 2:
The sealing gasket is made from elastomeric material that can deform and conform to the mating surfaces. This flexibility allows the gasket to maintain sealing contact despite pressure differential and manufacturing tolerances, preventing oxygen leakage.
2Stress or pressure
If pressure inside the chamber increases, then hyperbaric oxygen therapy function is achieved, but the sealing gasket may separate from the door
Solution Approach 1:
The sealing gasket includes a wing that extends in a direction perpendicular to the main sealing surface. This additional dimensional element allows the gasket to engage the door in multiple directions, preventing separation under pressure differential by distributing forces across different planes.
Solution Approach 2:
The elastomeric material of the gasket allows it to dynamically deform and maintain contact with the door under varying pressure conditions. The material's elasticity enables it to flex and conform as pressure changes, ensuring continuous sealing contact.
3Reliability
If the gasket surrounds the flange to improve sealing, then airtightness is enhanced, but the structure becomes more complex
Solution Approach 1:
The sealing gasket serves multiple functions simultaneously: it seals the interface between the door and chamber body, accommodates the flange structure, and the wing provides additional sealing engagement. This multi-functionality is achieved through a single integrated component rather than multiple separate sealing elements.
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 effectively seals the chamber by surrounding the flange and using wings to maintain airtightness, even under increased pressure, minimizing the risk of oxygen leakage.
Implementation Method 1
when an air pressure inside the chamber increases, the chamber is sealed as the first wing is brought into contact with the door by air between the chamber and the door

AI summary
A hyperbaric oxygen chamber including a sealing gasket configured to surround a first flange and partially surround a peripheral surface of an opening in order to seal a gap between a chamber equipped with the first flange protruding inwards from the peripheral surface of the opening and a door that opens inwards toward the chamber. The gasket is configured to surround the flange protruding from the opening of the chamber, thereby enabling the chamber to be sealed more effectively. Also, the wing of the gasket remains in close contact with an inner circumferential surface of the door, thereby enabling the gasket to maintain airtightness without being separated even when the pressure inside the chamber increases.
