Water Filter Clamp Assembly for Easy Cartridge Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional water filters are inconvenient to dismantle and replace filter cartridges due to complex fixing devices, which increases the effort required for regular maintenance.
Innovation Solution
A water filter design featuring first and second curved members, a hinge unit, and a fixing module with a hook member and fastener unit, allowing for easy engagement and disengagement of the filter components, facilitating simpler replacement of the filter cartridge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a threaded member is used to secure the metal ring, then the fixing device can maintain strong fixation, but the device becomes difficult to dismantle for filter cartridge replacement
Solution Approach 1:
The fixing device is divided into separate components: the metal ring and the handle member are independent parts that can be assembled and disassembled. The metal ring remains fixed on the junction, while the handle member can be detached for filter cartridge replacement and reattached afterward, resolving the contradiction between maintaining strong fixation and enabling easy dismantling.
2Reliability
If a complex fixing device with multiple components is used, then the fixation is secure, but the device complexity increases making maintenance difficult
Solution Approach 1:
The handle member integrates multiple functions into a single component: it provides the lever arm for tightening, houses the fastening mechanism, and serves as the detachment handle. This merging reduces the number of separate parts needed while maintaining secure fixation, thereby reducing device complexity without compromising reliability.

AI summary
A fixing device is adapted for installing on a water filter which includes a base seat and an outer shell. The fixing device includes first and second curved members adapted to be clipped on a junction between the base seat and the outer shell, and a fixing module. The fixing module includes a hook member and a fastener unit that includes a handle member and a ring member which is removably engaged with the hook member. The handle member is pivotable between a fastened position and a released position, where the ring member is permitted to be disengaged from the hook member to release the first and second curved members from the junction between the base seat and the outer shell. A water filter including the fixing device is also provided.
