Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If membrane separation devices use complex gas or liquid pipelines to achieve separation, then separation function is improved, but device volume and manufacturing cost increase
Solution Approach 1:
The patent combines the compression function and separation function into a single integrated device. The compressor body and separation chamber are merged into one structure, eliminating the need for separate pipelines and external compression equipment. This integration directly reduces device volume while maintaining separation functionality.
Solution Approach 2:
The compressor body serves multiple functions: it acts as both the compression chamber and the separation chamber. The piston performs both compression and drives the separation process. This multi-functionality eliminates auxiliary components and reduces overall device volume.
2Reliability
If membrane separation devices use complex gas or liquid pipelines to achieve separation, then separation function is improved, but manufacturing cost increases
Solution Approach 1:
By merging the compression and separation functions into one integrated device, the patent eliminates the need for complex external pipelines and multiple components. This simplification reduces manufacturing complexity and material requirements, thereby lowering production costs.
Solution Approach 2:
The patent extracts and eliminates unnecessary auxiliary components such as external pipelines, separate compression chambers, and complex valve systems. By removing these redundant elements, the design achieves separation functionality with fewer parts, reducing both manufacturing complexity and cost.
3Quantity of substance
If membrane separation devices are designed in multistage coaxial form to increase separation concentration, then separation concentration is improved, but device volume and cost substantially increase
Solution Approach 1:
The patent uses a dynamic piston mechanism that creates varying pressure zones during the compression cycle. This dynamic pressure variation enhances the separation concentration by forcing more gas through the membrane during high-pressure phases, achieving high separation concentration without requiring multiple static stages.
Solution Approach 2:
The patent changes the pressure parameter dynamically during operation. The piston creates alternating high and low pressure zones that enhance separation efficiency. This parameter variation allows a single-stage device to achieve separation concentration levels that would traditionally require multiple stages, avoiding volume and cost increases.
