Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hyperbaric oxygen chambers are either too large and heavy for domestic use or vulnerable to damage and leakage, posing safety risks due to their design and materials.
Innovation Solution
A portable and foldable hyperbaric oxygen chamber with a double chamber structure, featuring a body part divided into multiple cylindrical bodies that overlap for compact storage and external/internal zippers to prevent oxygen leakage, along with an oxygen controller and injection system to manage pressure and entry/exit safely.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a hard chamber is used to withstand high pressures, then the chamber can endure hyperbaric oxygen pressure, but the chamber becomes significantly large and heavy, making it unsuitable for domestic use
Solution Approach 1:
The chamber is divided into multiple cylindrical bodies (first, second, and third bodies) that can be separated and stored independently. When assembled, these segments form a complete chamber capable of withstanding hyperbaric pressure. This segmentation allows the chamber to be lightweight and easily stored when not in use, while maintaining structural integrity during operation.
Solution Approach 2:
The chamber utilizes a composite structure combining soft polyurethane material for the cylindrical bodies with rigid support elements. This composite approach provides sufficient pressure withstanding capability while maintaining portability and flexibility, avoiding the need for heavy aluminum alloy construction.
2Weight of moving object
If a soft polyurethane chamber is used for portability, then the chamber is easily carried and stored, but it cannot withstand high pressures and is vulnerable to impact damage
Solution Approach 1:
The soft chamber is divided into multiple rigid-supported segments that can be assembled together. Each segment contains internal reinforcement structures that provide local strength, while the overall assembly creates a pressure-resistant chamber capable of withstanding hyperbaric conditions.
Solution Approach 2:
The chamber design includes protective features such as impact-resistant materials and structural reinforcements positioned to absorb and distribute external forces before they can damage the soft polyurethane material. This beforehand cushioning allows the chamber to remain vulnerable-resistant while maintaining portability.
3Ease of operation
If a zipper is used for entrance and exit means, then the patient can easily enter and exit the chamber, but hyperbaric oxygen may leak through the zipper
Solution Approach 1:
A specialized seal mechanism acts as an intermediary between the zipper and the chamber interior. This seal prevents direct exposure of the zipper teeth to hyperbaric oxygen, blocking the leakage path while allowing the zipper to remain functional for patient entry and exit.
Solution Approach 2:
A flexible seal film is integrated with the zipper structure, conforming to the zipper's movement while maintaining an airtight barrier. This flexible film allows the zipper to open and close for patient access while preventing oxygen leakage during pressurized operation.
4Area of stationary object
If the chamber is designed as a single large structure, then it can provide adequate therapy space, but it cannot be folded or easily stored
Solution Approach 1:
The chamber is divided into multiple cylindrical bodies that can be collapsed and stored separately when not in use. During operation, these segments are assembled to form a complete chamber providing sufficient interior space for patient therapy, thus achieving both compact storage and adequate therapy space.
Solution Approach 2:
The cylindrical bodies are designed to nest within each other when collapsed, similar to nested dolls. The smaller segments fit inside larger ones, creating a compact storage configuration that is easy to transport and store, while maintaining the capability to expand into a full-sized therapy chamber when needed.
