Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If high pressure gas cylinders (200 bar) are used to store oxygen, then the oxygen storage capacity is increased, but the weight and bulkiness increase making them difficult to transport
Solution Approach 1:
The gas storage system is divided into two independent parts: a lightweight flexible bladder for gas storage and a rigid outer shell for structural support and adsorbent containment. This segmentation allows the heavy rigid structure to be minimized while the flexible bladder provides lightweight gas storage capacity.
Solution Approach 2:
Adsorbent material with porous structure is used to increase oxygen storage capacity within the flexible bladder. The porous material provides high surface area for gas adsorption, enabling compact storage of large volumes of oxygen without increasing the overall system weight or volume.
2Duration of action of moving object
If high pressure gas cylinders are used, then oxygen delivery duration is extended, but the device complexity and handling difficulty increase
Solution Approach 1:
The flexible bladder is pre-filled with oxygen gas at ambient pressure before use. This preliminary action eliminates the need for high-pressure filling operations during deployment, simplifying handling while maintaining extended delivery duration through the flexible storage medium.
Solution Approach 2:
The flexible bladder is designed as a single-use disposable component that is pre-filled and sealed. After use, it is discarded rather than refilled or maintained, eliminating complex refilling mechanisms and reducing device complexity while providing sufficient duration for emergency oxygen therapy.
3Weight of moving object
If portable oxygen concentrators are used, then weight and portability are improved, but the oxygen concentration and delivery capacity are reduced
Solution Approach 1:
The system changes the pressure parameter from high-pressure storage (200 bar cylinders) to ambient pressure flexible bladder storage. This parameter change reduces weight and improves portability while the adsorbent material compensates for the lower pressure by increasing storage density through adsorption mechanisms.
Solution Approach 2:
The system uses a composite structure combining flexible bladder material for containment, rigid shell for structural support, and adsorbent material for gas storage enhancement. This composite approach achieves high oxygen delivery capacity in a lightweight portable format by leveraging the strengths of each material type.
4Adaptability or versatility
If ambient air is drawn in for oxygen extraction, then portability is improved, but the system cannot operate in contaminated environments
Solution Approach 1:
Oxygen is pre-stored in the flexible bladder before deployment, eliminating the need to draw ambient air during operation. This preliminary storage action allows the system to operate independently of environmental air quality, providing adaptability to contaminated environments such as CO poisoning scenarios.
