Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a target component is liquefied and collected in a container, then the target component can be collected, but the system may be blocked by the liquefied substance and the target component cannot be stably fractionated
Solution Approach 1:
The invention changes the temperature parameter of the collection tube, switching between a first temperature (for adsorption) and a second temperature higher than the first (for desorption). This temperature parameter change allows the adsorbent to alternately adsorb and desorb the target component, preventing system blockage while enabling stable fractionation and collection of the target component.
2Manufacturing precision
If precision distillation apparatus is used to extract target component with high purity, then purification quality is improved, but the amount of purified gas is limited to 1 g or less
Solution Approach 1:
The invention uses an adsorbent material with porous structure in the collection tube. The adsorbent can adsorb large amounts of target component from the gas phase, enabling collection of quantities exceeding 1 g while maintaining high purification quality. The porous structure provides large surface area for adsorption, resolving the contradiction between purification quality and quantity.
3Quantity of substance
If gas is handled for purification, then target component can be extracted, but highly accurate purification is difficult to realize
Solution Approach 1:
The invention introduces an adsorbent as an intermediary substance between the gas phase and collection container. The adsorbent mediates the purification process by selectively adsorbing the target component from the gas stream, enabling highly accurate purification that is difficult to achieve through direct gas handling alone.
