Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing membrane liquid purification devices are limited by their need to be permanently mounted near the liquid source, lack versatility in handling multiple sources, and suffer from inefficient liquid composition uniformity during filtration, leading to reduced efficiency and reliability.
Innovation Solution
A membrane liquid purification device with a liquid withdrawal means that allows for purification from the surface layer of the liquid, using a flexible tube and floating element or hinge mechanism to regulate liquid intake, ensuring uniform composition and automatic process termination based on set liquid levels or volume, equipped with features like adjustable stops and screens to manage liquid flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the device is permanently mounted near the liquid source, then the purification process is stable and reliable, but the device lacks versatility and cannot be moved to different locations or sources
Solution Approach 1:
The device incorporates a floating element that dynamically adjusts the liquid withdrawal means position based on liquid level changes. This dynamic adjustment allows the device to adapt to different liquid sources and levels while maintaining stable operation, resolving the contradiction between reliability and versatility.
2Device complexity
If liquid is withdrawn from middle layers of the container, then the device structure is simple, but the liquid composition becomes uneven leading to reduced purification efficiency
Solution Approach 1:
The floating element positions the liquid withdrawal means at the liquid surface level, creating a localized withdrawal zone with uniform composition. This ensures that only liquid from the upper layer with consistent impurity distribution is purified, maintaining high purification efficiency without significantly complicating the device structure.
3Quantity of substance
If the liquid purification unit processes liquid from varying composition layers, then all liquid can be purified, but the service life of the pressure increasing means and reliability of the purification unit are reduced
Solution Approach 1:
The floating element performs preliminary action by positioning the liquid withdrawal means to selectively withdraw liquid from the upper layer with more uniform composition before it enters the pressure increasing means and purification unit. This preliminary selection of liquid source prevents sudden composition changes that would stress the pressure increasing means and reduce purification unit reliability.
