Flexible Membrane Fixing Means for Water Jug Filters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filtering devices for potable water often experience reduced efficiency and operational issues due to air bubbles forming under fixation means, which can close the effective cross-section and hinder the filtering process.
Innovation Solution
A filtering device with a body filled with particulate material and a lid featuring water inlets and air outlets, utilizing a flexible polymeric fixing means with a slit valve to prevent material escape and enhance efficiency, where the slit width increases during flow and is sized to accommodate the particulate material, and a cone-shaped cuff with collars for improved sealing and reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixation means (net/membrane/laying) is used to hold filtering material, then the filtering material is secured and prevented from escaping, but air bubbles accumulate under the fixation means and close the effective cross-section, reducing filtering efficiency
Solution Approach 1:
The patent employs a flexible membrane as the fixation means instead of rigid nets or layings. This flexible membrane can deform to accommodate air bubbles and maintain contact with the filtering material, preventing material escape while allowing air to pass through without forming blocking bubbles. The flexibility enables the membrane to conform to the contours of the filtering material and sealing surfaces, ensuring both secure fixation and continuous liquid flow paths.
Solution Approach 2:
The fixation means is designed with dynamic characteristics, allowing it to adapt its shape and position in response to pressure changes and air bubble formation. The membrane can dynamically adjust during operation to maintain effective sealing and flow paths, rather than being a static structure that becomes blocked by air accumulation.
2Reliability
If a net made from textile material with complex construction (convex elements, ribs) is used, then filtering material is secured, but the construction becomes insufficient for manufacturing and increases complexity
Solution Approach 1:
The patent replaces complex textile constructions with a simple flexible membrane that achieves fixation through its material properties and geometric configuration rather than complex structural elements. The membrane's simplicity makes it easier to manufacture while maintaining reliable fixation of the filtering material.
Solution Approach 2:
The invention changes the key parameter of the fixation means from complex structural geometry (convex elements, ribs) to simple geometric parameters (membrane area, thickness, elasticity). This parameter change simplifies manufacturing while maintaining or improving fixation reliability through the membrane's ability to conform and seal.
