Water Filter Actuating Device for Tool-Free Element Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water filter systems require complex and time-consuming processes for replacing filter elements, often resulting in insufficient cleaning and increased pressure loss, especially when laypersons attempt maintenance due to stuck union nuts or the need for tools with flange screw connections.
Innovation Solution
An actuating device with a lever articulated on the filter head, a shut-off element, and a linkage system that allows the filter cup to be easily moved axially between closed and removal positions, eliminating the need for tools and ensuring secure attachment and easy replacement of filter elements, with a sealing mechanism that maintains integrity regardless of pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If a replaceable filter element is used in a filter cup with union nut or flange screw connection, then the filter can be replaced for cleaning, but the replacement process becomes time-consuming and complicated requiring tools
Solution Approach 1:
The filter system is segmented into a filter head, filter cup, and replaceable insert. The filter cup with integrated actuating device can be quickly removed from the filter head without tools, and the insert can be independently replaced within the filter cup, enabling modular and tool-free maintenance
Solution Approach 2:
The filter cup is equipped with an integrated actuating device that enables the user to easily remove and reattach the filter cup without requiring external tools or specialized knowledge. The system is designed to be self-servicing, allowing laypersons to perform maintenance independently
2Reliability
If the filter cup is securely attached to the filter head, then filter integrity is maintained under pressure, but the filter cup becomes difficult to remove for replacement
Solution Approach 1:
The connection between filter cup and filter head is dynamic rather than static. The filter cup can be firmly secured during operation to maintain reliability, but can be easily released when needed for replacement through the actuating device, allowing the system to transition between secure and removable states
Solution Approach 2:
The actuating device serves as an intermediary mechanism between the user and the filter cup attachment. It provides a simple interface for securing and releasing the filter cup, mediating between the need for secure attachment and easy removal without requiring direct manipulation of complex fastening mechanisms
3Loss of substance
If manual shut-off of inlet and outlet is required for filter replacement, then water loss is prevented, but the replacement process becomes more complicated
Solution Approach 1:
The shut-off function and filter cup retention function are merged into a single integrated actuating device. By operating this single device, the user simultaneously closes the inlet/outlet and secures or releases the filter cup, simplifying the replacement procedure while ensuring water loss prevention
Solution Approach 2:
The actuating device performs multiple functions: it acts as a shut-off mechanism for the inlet/outlet, a retention mechanism for the filter cup, and a release mechanism for filter replacement. This multi-functional design reduces the number of separate components and steps required for maintenance
