Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If membrane separation is used to produce high-purity gas from low-concentration raw gas, then high-purity gas can be obtained, but multiple purification stages are required resulting in high production cost
Solution Approach 1:
The system divides the gas purification process into multiple modular units, each containing a membrane separation module and an adsorption module connected in series. These modular units can be independently configured and scaled, allowing the system to achieve high purity through staged purification while maintaining flexibility in system design and reducing overall manufacturing complexity
Solution Approach 2:
The patent combines membrane separation technology and adsorption separation technology into a single integrated system. The membrane separation module performs preliminary concentration enrichment, and the adsorption module completes the purification, creating a synergistic effect that achieves high-purity gas production more efficiently than either technology alone would require
2Manufacturing precision
If multiple stages of purification are used to produce high-purity gas, then gas purity is improved, but the footprint and weight of the device increase
Solution Approach 1:
The adsorption module is positioned directly above the membrane separation module, with the second housing disposed on the first housing. This vertical nesting arrangement allows the permeate gas outlet of the membrane module to communicate directly with the second gas inlet of the adsorption module, maximizing space utilization and minimizing the device footprint while maintaining multi-stage purification functionality
Solution Approach 2:
The system transitions from a horizontal arrangement of purification stages to a vertical arrangement. By stacking the membrane separation module and adsorption module vertically, the patent reduces the horizontal footprint of the device while maintaining the multi-stage purification process, effectively utilizing the vertical dimension to solve the space constraint
3Manufacturing precision
If multiple stages of purification are used to produce high-purity gas, then gas purity is improved, but the device weight and manufacturing cost increase
Solution Approach 1:
The vertical stacking of the membrane separation module and adsorption module reduces the overall device weight by eliminating the need for extensive horizontal support structures and connecting pipes. The compact vertical configuration minimizes material requirements while maintaining the multi-stage purification functionality
Solution Approach 2:
The modular design allows each purification stage to be independently optimized and manufactured, enabling the use of lighter materials and more efficient manufacturing processes for each module. This segmentation facilitates easier assembly and reduces the overall weight compared to a monolithic multi-stage system
