Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a gas storage container with water-soluble material or breathable film is used to provide oxygen independently, then oxygen supply is achieved, but the amount of oxygen filling and release cannot be effectively controlled and the effect of oxygen release is poor
Solution Approach 1:
The patent changes the physical parameter of membrane thickness to control oxygen release. By adjusting the thickness of the breathable membrane from 5-500 μm, the oxygen transfer rate is precisely controlled, solving the problem of uncontrolled oxygen release in prior art systems
Solution Approach 2:
The patent employs a breathable membrane with controlled porosity and thickness to regulate oxygen passage. The membrane's physical structure allows selective oxygen transfer while maintaining safety, addressing the lack of control in previous water-soluble material approaches
2Reliability
If a gas storage container with small holes covered by water-soluble material is used, then oxygen can be supplied, but the oxygen release effect is poor leading to poor treatment effect and safety risk
Solution Approach 1:
The patent optimizes the membrane thickness parameter within 5-500 μm to achieve both safety and efficient oxygen release. This physical parameter change eliminates the need for water-soluble materials while maintaining controlled oxygen transfer rates that are both safe and effective
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system ensures controlled oxygen release, enhances skin penetration, and improves therapeutic efficacy by maintaining oxygen concentration and pressure, while ensuring safety and sterility.
Implementation Method 1
the bag body wall of the bag body is composed of a breathable part for passing through oxygen and controlling the rate of oxygen transfer and diffusion

AI summary
Oxygen-containing preparation for treating acne and wounds, a preparation method and an application device thereof. The oxygen-containing formulation comprises an oxygen bag that comprises a bag body configured for containing oxygen. A bag body wall of the bag body consists of a gas-permeable part configured for permeation of oxygen and controlling an oxygen transfer diffusion rate, and a gas-impermeable part. Alternatively, the bag body wall of the bag body consists of a gas-permeable part configured for permeation of oxygen and controlling the oxygen transfer diffusion rate. The thickness of the gas-permeable part is 5-500 μm, and the oxygen permeability of the gas-permeable part is 0.0000001 cm2·s·0.1 MPa-0.1 ml/cm2·s·0.1 MPa. The oxygen-containing formulation not only provides oxygen molecules for acne and the wound surface, thereby killing anaerobic bacteria and promoting wound healing, but provides oxygen partial pressure and oxygen pressure intensity, thereby ensuring the oxygen content during use.
