Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing oxygen delivery systems for breathable gas are often bulky, heavy, and not portable, making it inconvenient for individuals to access high-quality air, especially in environments with poor air quality or at high altitudes, and there is a growing need for a portable solution that provides enhanced oxygen supply for health and wellness.
Innovation Solution
A portable oxygen delivery apparatus comprising a compact storage vessel and a delivery system with a valve assembly that allows for inhalation and exhalation of breathable gas, featuring a design that is lightweight, foldable, and adaptable to the user's facial structure, enabling easy transportation and use in various settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional oxygen delivery systems are used, then oxygen supply quality is improved, but portability and weight are worsened
Solution Approach 1:
The apparatus is divided into separate functional modules: a collapsible bellows mechanism for gas storage and delivery, a facial interface component, and a carrying case. This segmentation allows each component to be optimized independently and facilitates portability through selective assembly and disassembly.
Solution Approach 2:
The bellows mechanism uses dynamic expansion and contraction to deliver oxygen gas on demand rather than requiring a rigid pressurized tank. The collapsible nature of the bellows reduces weight and volume while maintaining adequate oxygen supply capability.
2Reliability
If traditional oxygen tanks are used, then oxygen delivery capability is improved, but device complexity and bulk are worsened
Solution Approach 1:
The bellows mechanism is manually operated by the user through simple expansion and contraction movements. This self-service approach eliminates the need for complex electronic controls, motors, or pressurization systems while maintaining reliable oxygen delivery capability.
Solution Approach 2:
The apparatus uses pneumatic principles through the bellows mechanism to store and deliver oxygen gas. The flexible bellows expand to store gas and contract to deliver it, providing a simple yet effective pneumatic system without complex components.
3Quantity of substance
If oxygen is stored in a pressurized tank, then oxygen availability is improved, but portability is worsened
Solution Approach 1:
The collapsible bellows mechanism nests within a compact carrying case when not in use. The bellows can be compressed to minimal volume and stored inside the case, which itself can be carried in a backpack or bag, effectively nesting the oxygen delivery system within portable carrying structures.
Solution Approach 2:
The bellows dynamically change volume from expanded (during oxygen delivery) to compressed (during storage). This dynamic volume adjustment allows the apparatus to occupy minimal space during transport while providing adequate oxygen storage capacity during use.

AI summary
A portable breathable gas delivery device including a pressure vessel for storing the breathable gas under pressure and a valve coupled to the pressure vessel through which the breathable gas can be selectively released. The pressure vessel is enclosed in a housing having a first portion that at least partially encloses the pressure vessel and a second portion that partially encloses a chamber coupled to the pressure vessel via the valve into which the breathable gas can be released for breathing by a user. The second portion together with a user's facial structure forms a substantially closed enclosure. The chamber has an opening shaped and formed to interface with the user's facial structure.
