Solution Overview
Problem
Conventional hypoxic training systems require a nitrogen supply and struggle with precise control of oxygen ratios, leading to inconvenient and costly operations, as well as potential negative side effects like fatigue due to incorrect configuration.
Innovation Solution
A hypoxic training system that generates gas with a desired oxygen ratio using a membrane and solenoids, eliminating the need for a nitrogen supply and allowing for precise control of oxygen ratios through adjustable solenoid openings and a speed valve, with a controller dynamically adjusting the oxygen ratio based on blood oxygen saturation levels to minimize fatigue and maximize benefits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If nitrogen supply is used to generate hypoxic gas, then hypoxic training can be provided, but the system becomes inconvenient and costly due to nitrogen tanks and expensive oxygen analyzers
Solution Approach 1:
The patent extracts and eliminates the nitrogen supply component from the hypoxic training system. Instead of using nitrogen tanks to create hypoxic gas, the system uses a membrane that selectively removes oxygen from ambient air, thereby taking out the problematic nitrogen supply infrastructure while maintaining the core hypoxic training function
Solution Approach 2:
The patent introduces a membrane as an intermediary substance between ambient air and the user. This membrane selectively permits nitrogen and other gases to pass through while blocking oxygen, thereby mediating the gas composition to achieve hypoxic conditions without requiring nitrogen tanks or expensive oxygen analyzers
2Reliability
If nitrogen mixing is used to control oxygen ratio, then hypoxic gas can be generated, but precise control is difficult requiring expensive oxygen analyzers
Solution Approach 1:
The membrane acts as a passive intermediary that inherently controls oxygen rejection based on its material properties and operating conditions (temperature, pressure, flow rate). This eliminates the need for active feedback control systems, oxygen analyzers, and complex mixing mechanisms, thereby reducing device complexity while maintaining reliable oxygen ratio control
Solution Approach 2:
The system controls the oxygen ratio by changing physical parameters such as temperature, pressure, and gas flow rate across the membrane. These parameter changes directly affect the membrane's oxygen rejection characteristics, providing a simple yet effective control mechanism without requiring expensive sensors or complex feedback systems
3Ease of operation
If fixed oxygen ratio is used in hypoxic training, then training can be provided, but negative side effects like fatigue occur due to incorrect configuration
Solution Approach 1:
The system transitions from a fixed oxygen ratio configuration to a dynamic adjustment mechanism. The membrane-based system allows real-time modification of oxygen rejection based on user response, enabling the training protocol to adapt dynamically and prevent harmful effects like fatigue while maintaining ease of operation
Solution Approach 2:
The system incorporates feedback mechanisms to monitor user response during hypoxic training and adjusts the oxygen ratio accordingly. This feedback loop allows the system to detect signs of fatigue or non-responsiveness and modify the hypoxic stimulus to remain within beneficial parameters, thereby eliminating negative side effects

AI summary
A hypoxic training system is provided that dynamically adjusts the oxygen ratio in the gas provided to the user during a hypoxic training session based on the blood oxygen saturation (SPO2) level of the user. During a first training period, the hypoxic training system provides gas according to a first oxygen ratio. When it is determined that the SPO2 level of the user has reached a target SPO2 level, the hypoxic training system may provide a recovery period, during which gas according to a second oxygen ratio is provided to the user. When it is determined that the SPO2 level of the user has fallen more than a predetermined threshold below the target SPO2 level during the recovery period, the hypoxic training system may provide gas according to an increased first oxygen ratio during a subsequent training period.
