Water Purifier Filter Locking Structure for Compact RO Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional water purifiers face issues with space wastage due to larger membrane shells and loose connections of filter elements under internal water pressure, affecting structural stability and operation.
Innovation Solution
A water purifier design featuring a membrane shell with a locking mechanism that secures first and second class filter elements, allowing vertical installation of the reverse osmosis membrane, saving space and ensuring stability, and includes a toggle disk for visual inspection and replaceable inner frames for different filter materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the membrane shell is made larger to ensure structural stability and accommodate all filter elements, then the structural stability is improved, but space waste increases
Solution Approach 1:
The patent changes the installation orientation of the RO filter element from horizontal to vertical, utilizing the height dimension of the membrane shell. This allows the membrane shell to be smaller in footprint area while maintaining sufficient volume to accommodate all filter elements, thereby reducing space waste without compromising structural stability.
2Ease of operation
If the filter element uses threaded connection to ensure installation sealing and convenience, then the ease of operation is improved, but continuous vibration causes the filter element to become loose
Solution Approach 1:
The locking mechanism is engaged after the threaded connection is made, performing a preliminary locking action that prevents the filter element from loosening under continuous vibration. This two-stage connection process (threading followed by locking) ensures both ease of installation and long-term connection stability.
Solution Approach 2:
The locking mechanism applies a preliminary anti-action force that counteracts the loosening tendency caused by continuous vibration. By pre-applying this counteracting force through the locking blocks and toggle disks, the filter element remains securely connected despite vibrational stresses.
