Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If inert gas (such as argon) is continuously introduced into the double-layer jacket to meet strict sealing requirements, then the sealing performance is improved, but the cost increases and the gas cannot be recycled
Solution Approach 1:
The patent replaces expensive inert gas (argon) with activated carbon, a much cheaper material that can be disposed of after use. The activated carbon is introduced into the double-layer jacket, where it absorbs moisture and oxygen, then is recovered and regenerated through heating, creating a cost-effective cycling system that eliminates the need for continuous expensive inert gas supply
Solution Approach 2:
The patent changes the chemical state of activated carbon through temperature variation. In the absorbing state (lower temperature), activated carbon captures moisture and oxygen. Through heating (higher temperature), the activated carbon is regenerated and releases the absorbed substances. This parameter change enables the cycling between absorption and regeneration phases
2Loss of substance
If activated carbon is used to replace inert gas for controlling water and oxygen concentrations, then the cost is reduced, but the recycling mechanism must be implemented to maintain sealing performance
Solution Approach 1:
The patent divides the activated carbon system into separate functional zones: the double-layer jacket for absorption, the regenerating device for thermal regeneration, and the circulation system for material transport. This segmentation allows each component to perform its specific function efficiently while maintaining overall system simplicity
Solution Approach 2:
The patent introduces a circulation device as an intermediary between the absorption zone (double-layer jacket) and the regeneration zone (regenerating device). This intermediary system, comprising conveying mechanisms and switching valves, enables the activated carbon to be transported and cycled between zones, maintaining sealing performance while allowing material recovery
