Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional spiral separation membrane elements face challenges in reducing fluid resistance and pressure loss, with limited morphology options for the channel material on the feed side, restricting the degree of shape change and efficiency in separating fluids.
Innovation Solution
The spiral separation membrane element incorporates a band-shaped region on the feed-side surface with resin bodies arranged in a striped pattern, allowing for enhanced shape flexibility and reduced resistance by overlaying resin bodies on each other, thereby improving the flow path and reducing pressure loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional net structures are used for channel material, then the structure is simple to manufacture, but the pressure loss is high and water production is limited
Solution Approach 1:
The channel material is divided into multiple resin bodies arranged in a net structure, where each resin body forms an independent flow channel. This segmentation allows optimization of individual channel characteristics while maintaining overall structural integrity, reducing pressure loss and increasing water production compared to conventional single-structure nets
Solution Approach 2:
The invention transitions from conventional two-dimensional net structures to a three-dimensional configuration where resin bodies extend in multiple directions, creating complex flow paths that reduce resistance. The resin bodies are arranged with specific spacing and orientation to optimize fluid flow in three-dimensional space, thereby reducing pressure loss while increasing productivity
2Adaptability or versatility
If the channel material shape is fixed to conventional net structures, then the manufacturing process is simple, but the adaptability to different fluid types is limited
Solution Approach 1:
Different regions of the channel material can have different resin body configurations, densities, and shapes tailored to specific fluid processing requirements. This allows optimization of local flow characteristics for different fluid types while maintaining overall structural consistency, enhancing adaptability without excessive complexity
Solution Approach 2:
The channel material structure can be dynamically adjusted or selected based on fluid type requirements. The modular resin body design allows reconfiguration of the net structure to match specific application needs, providing versatility while keeping the base manufacturing process relatively simple through standardized components
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration enables increased water production and reduced flow resistance, while maintaining the separation efficiency by allowing for customizable channel material shapes based on the type of fluid being processed.
Implementation Method 1
The resistance (i.e., pressure loss) generated when the raw fluid flows through a flow path on the feed side of the spiral separation membrane element is greatly dominated by a channel material on the feed side
Implementation Method 2
when a raw fluid is supplied to one surface of the separation membrane, a permeate fluid separated from the raw fluid by permeating the separation membrane is obtained from the other surface
Implementation Method 3
a spiral separation membrane element adapted to separate components in a fluid by a reverse osmosis technique or a filtration technique using a separation membrane
