Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing oxygen generators fail to switch oxygen outlet modes in real time according to a user's physical condition, leading to low oxygen utilization and breathing discomfort, especially during varying physical activities or abnormal breathing.
Innovation Solution
A control method that integrates direct current and pulse oxygen outlet modes, using models to adjust solenoid valves based on user physical signs like blood oxygen saturation, heart rate, and breathing frequency, establishing a nonlinear mapping relationship to optimize oxygen delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a single pulse oxygen generator is used, then oxygen utilization rate is improved during normal breathing, but oxygen supply is insufficient during physical activities or abnormal breathing
Solution Approach 1:
The patent combines direct current oxygen outlet mode and pulse oxygen outlet mode into a single oxygen generator system. The controller switches between DC mode (for immediate oxygen supply during abnormal breathing or physical activities) and pulse mode (for normal breathing to improve utilization rate), thereby resolving the contradiction between oxygen supply sufficiency and oxygen utilization rate.
2Reliability
If a single direct current oxygen generator is used, then oxygen supply is continuous and sufficient, but oxygen utilization rate decreases due to constant oxygen flow
Solution Approach 1:
The patent implements dynamic switching between direct current mode and pulse mode based on real-time detection of user breathing state and physical condition. The controller adjusts the oxygen outlet mode dynamically: using pulse mode during normal breathing to improve utilization rate, and switching to DC mode when abnormal breathing or physical activities are detected, thus resolving the contradiction between continuous supply and utilization efficiency.
3Device complexity
If oxygen mode is fixed and cannot switch, then device complexity is reduced, but adaptability to different physical conditions deteriorates
Solution Approach 1:
The patent designs the oxygen generator with multi-functionality, enabling it to operate in both direct current mode and pulse mode. The controller detects user physical conditions (breathing state, heart rate, etc.) and automatically switches between modes, making the device adaptable to various physical conditions while maintaining reasonable structural complexity through integrated control.

Function Achieved in This Case
Enhances oxygen utilization rate while ensuring user breathing comfort by dynamically switching between outlet modes based on real-time physical data analysis.
Implementation Method 1
because the molecular sieve has stronger adsorption force on nitrogen and other gas molecules than oxygen, nitrogen is adsorbed by the molecular sieve, and oxygen passes through the molecular sieve to form high-concentration oxygen
Implementation Method 2
adjusting an opening of the direct current oxygen outlet solenoid valve to the first opening adjustment value in the first preset time period B
