Water Filter Handle Radial Displacement for Secure Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water filter elements in refrigeration and fountain systems require complex removal and installation processes due to their limited lifespan, often necessitating the use of various fasteners and covers which can be cumbersome for users.
Innovation Solution
A water filter element design featuring a handle with a locking protrusion and guide structure that allows for self-alignment and secure engagement within a water purification system, enabling simple installation and removal through radial displacement and engagement with a lock, facilitated by a guide structure on the compartment cover.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional water filter elements use complex fasteners and covers for secure installation, then the filtration reliability is improved, but the ease of operation deteriorates
Solution Approach 1:
The filter assembly is divided into separable components: the filter element and the compartment cover. The locking protrusion on the filter element can be disengaged from the lock on the compartment cover, allowing easy separation without complex fasteners. This segmentation enables simple removal and installation while maintaining secure connection during operation.
Solution Approach 2:
The guide structure on the compartment cover automatically guides the filter element into proper alignment during installation. The locking protrusion and lock mechanism automatically engage when the filter element is inserted, eliminating the need for manual fastening operations. This self-service mechanism simplifies user operation while ensuring reliable installation.
2Stability of the object's composition
If multiple fasteners and covers are used to secure the water filter element, then the stability of installation is improved, but the device complexity increases
Solution Approach 1:
The locking mechanism and guide structure are integrated into the compartment cover as a single unified component. The lock and guide structure work together as one assembly that simultaneously provides alignment guidance and secure locking, eliminating the need for separate fasteners and reducing overall system complexity.
Solution Approach 2:
The complex multi-fastener system is extracted and replaced with a single locking protrusion and lock mechanism. This simplified fastening system achieves the same installation stability with fewer components, reducing device complexity while maintaining secure filter element attachment.

AI summary
A water filter element for use within a water purification system includes a housing, a locking protrusion, and a handle. The housing comprises a first end comprising a water inlet and a water outlet and a second end opposite the first end. The locking protrusion is positioned on the housing proximate the second end of the housing, and the handle is disposed on the second end of the housing. The handle comprises an outer side oriented away from the first end of the housing. When the water filter element is installed within the water purification system, the outer side of the handle causes the second end of the housing to be radially displaced such that the locking protrusion is engaged by a lock of the water purification system. Water filter assemblies including the water filter element and methods of installing and removing the water filter element are also described.
