Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water filters for refrigeration appliances are often specific and cannot be easily interchangeable across different models, limiting flexibility and compatibility.
Innovation Solution
A water filter assembly design featuring a separable arcuate body with a pin that interacts with a bypass valve to control water flow, allowing for the use of various filter bodies and geometries without requiring modification to the appliance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If water filters are custom or specific to the refrigeration appliance, then the filter can be optimized for that specific appliance, but the filter cannot be used or mixed among various refrigeration appliances
Solution Approach 1:
The water filter assembly is divided into two separable components: a reusable arcuate body (housing) and a replaceable filter body. The arcuate body contains the bypass valve mechanism and interfaces with the appliance, while the filter body can be detached and replaced. This segmentation allows different filter bodies to be used with the same arcuate body, enabling compatibility across various refrigeration appliances while maintaining optimized performance through the standardized arcuate body design.
Solution Approach 2:
The arcuate body is designed with universal compatibility features that allow it to interface with multiple different refrigeration appliance models. The standardized arcuate body with its specific pin configuration and bypass valve mechanism can accommodate various filter bodies, making the overall assembly adaptable to different appliance types while maintaining reliable water filtration functionality.
2Adaptability or versatility
If a separable filter body design is used, then various filter types can be used among various refrigeration appliances, but the integration complexity increases
Solution Approach 1:
By separating the filter body from the arcuate body, the design enables easy replacement of filter elements without replacing the entire assembly. The segmentation creates simple, distinct components that can be manufactured independently and assembled through straightforward interface mechanisms, reducing overall system complexity despite enabling multiple filter type compatibility.
Solution Approach 2:
The filter body is extracted as a separate, removable component from the arcuate body. This extraction allows the filter element to be independently replaced while the arcuate body with its bypass valve mechanism remains in place, simplifying maintenance and enabling compatibility with various filter types without requiring complex integrated designs.
3Ease of operation
If the pin is configured to automatically close the bypass valve, then water flow control is improved, but the mechanism complexity increases
Solution Approach 1:
The pin is pre-configured in the arcuate body to automatically engage with and close the bypass valve when the filter body is properly installed. This preliminary positioning of the pin ensures that water flow control is automatically managed upon assembly, eliminating the need for separate manual valve control mechanisms and simplifying the overall operation while maintaining effective water flow management.
Solution Approach 2:
The bypass valve mechanism is designed to be self-actuating through the pin configuration. When the filter body is installed, the pin automatically closes the bypass valve without requiring external intervention or complex control systems. The mechanism serves itself by using the installation action to trigger the valve closure, improving ease of operation while keeping the mechanism relatively simple.

AI summary
A water filter assembly for a refrigeration appliance and an arcuate body for a water filter assembly are provided. The arcuate body includes a body forming an arcuate section. A pin extends along a longitudinal extension of the body and is configured to contact a bypass valve to close the bypass valve when the arcuate body is positioned within a chamber at the water filter assembly. The water filer assembly includes a filter body separable from the arcuate body.
