Solution Overview

Problem

Existing exercise with oxygen therapy (EWOT) devices are cumbersome, difficult to transport, and lack positive air pressure in their bladders, which slows oxygen delivery to users. Additionally, most devices only supply a single oxygen source without the ability to switch between multiple sources during exercise.

Innovation Solution

The proposed EWOT apparatus features two inflatable bladders with different oxygen levels, supported by a frame with a weighted member to maintain positive pressure. This system allows for selective delivery of high and low oxygen concentrations to the user during exercise, with a control switch that can be manually or automatically operated to switch between oxygen sources.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of stationary object

If a large rectangular plastic bag is used to store oxygen at ambient pressure, then the device can hold air for extended periods, but the device occupies significant floor and wall space and is difficult to transport

Engineering Contradiction:
Improveair storage durationVSAvoidfloor space occupation
Core Design Contradiction:
Duration of action of stationary objectVSArea of stationary object

Solution Approach 1:

The patent implements nesting by placing the collapsible bladder inside a compact cylindrical housing. When the bladder is deflated or contains minimal air, it collapses into a compact form that fits within the housing, reducing the device's footprint from a large rectangular configuration to a space-efficient cylindrical shape that can be easily stored and transported.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The patent employs a collapsible bladder that dynamically changes volume based on air content. As air is consumed during therapy, the bladder automatically collapses and reduces in size, allowing the device to transition from a large expanded state during use to a compact collapsed state for storage, eliminating the need for large fixed space.

Inventive Principle:
Principle #15Dynamics

2Device complexity

If ambient pressure oxygen storage is used, then the device structure is simple, but oxygen delivery speed to users is slow

Engineering Contradiction:
Improvestorage system simplicityVSAvoidoxygen delivery speed
Core Design Contradiction:
Device complexityVSSpeed

Solution Approach 1:

The patent applies pneumatic principles by using a pressurized bladder system where compressed air is stored at elevated pressure. This pneumatic storage enables rapid oxygen delivery during exercise by maintaining pressure that forces air through the delivery system quickly, while the bladder's collapsible nature allows for compact storage when not in use.

Inventive Principle:
Principle #29Pneumatics and hydraulics

3Device complexity

If a single air source is used, then the device structure is simple, but the device cannot switch between multiple oxygen sources during exercise

Engineering Contradiction:
Improveair source configurationVSAvoidoxygen source switching capability
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent implements multi-functionality by designing a dual-bladder system where each bladder can store different types or concentrations of oxygen. The system includes switching mechanisms that allow users to select between different oxygen sources based on their specific needs, such as switching between high-concentration oxygen for intense exercise and lower-concentration oxygen for recovery periods.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

An exercise with oxygen therapy (EWOT) apparatus for rejuvenating oxygen- depleted cell tissue and simulating high altitude oxygen conditions. The EWOT apparatus includes a first cylindrical bladder for providing oxygen -enriched air and a second bladder for providing lower-purity hypoxic air. The first bladder is retained within an open, lightweight rectangular-shaped frame having vertical frame members. An air supply source provides the oxygen-enriched and hypoxic air to the first and second bladders, respectively. A control switch, which can be manually and/or programmed to automatically operate, selectively delivers the oxygen-enriched and/or hypoxic air to a breathing mask worn by a user while exercising on exercise equipment. The first bladder includes a plurality of weights which provide a positive pressure to the air therein. The cylindrical first bladder is attached to the vertical frame members with slidable rings and expands and collapses in a vertical direction when being filled or during use, respectively.
