Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If prefilled oxygen bottles or canisters are used, then users can obtain pure oxygen for inhalation, but the products are costly and must be disposed of after use
Solution Approach 1:
The oxygen canister is designed to be refillable using a refill kit that allows users to recharge the canister with oxygen at home or in the field, eliminating the need for disposal and purchase of new canisters. The system enables self-service refilling through chemical reaction between oxygen source material and water.
Solution Approach 2:
Instead of discarding used oxygen canisters, the invention allows for recovery and reuse of the canister by refilling it with oxygen generated from the refill kit containing oxygen source material and water.
2Weight of moving object
If prefilled oxygen canisters are used, then users can carry portable oxygen, but the canisters are under pressure which may be undesirable in certain situations
Solution Approach 1:
The invention changes the pressure parameter by generating oxygen at atmospheric pressure through chemical reaction rather than storing compressed oxygen. The oxygen is produced on-demand in the canister without requiring high-pressure storage conditions.
3Adaptability or versatility
If portable oxygen generators using concentrators are used, then oxygen can be generated from air, but the devices are large and costly
Solution Approach 1:
The invention extracts only the essential oxygen generation function from complex concentrator systems, using a simplified chemical reaction approach with oxygen source material and water that eliminates the need for large compressors, sieves, and control systems while maintaining portability.
4Reliability
If aluminum canisters are used for oxygen storage, then oxygen can be contained and delivered, but the products are costly
Solution Approach 1:
The invention replaces expensive aluminum canisters with refillable plastic or metal containers that can be reused multiple times. The refill kit uses inexpensive chemical oxygen source material and water to generate oxygen, reducing overall system cost.
