Filter Fastening Unit Assembly Tool-Free Exchange Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water purifier filter replacement methods require tools and have complex structures, making it difficult for general users to conveniently attach and detach filters without damaging the device.
Innovation Solution
A filter fastening unit assembly with a base, housing, filter coupling part, and lever that allows for tool-free one-touch filter exchange, featuring a simple part and passage structure, where the lever rotates to move the housing and filter in conjunction, enabling easy attachment and detachment without rotating the filter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a direct connection scheme is used to connect the fitting to the flow passage, then the filter can be securely fastened, but a tool is necessary for attachment and detachment, making it difficult for general users to replace
Solution Approach 1:
The lever is designed to rotate between a first position (filter attached) and a second position (filter detached), transforming the static connection into a dynamic one that users can easily control through simple rotational motion without requiring tools
Solution Approach 2:
The lever acts as an intermediary mechanism between the user's manual operation and the filter connection state. By rotating the lever, users indirectly control the engagement and disengagement of the filter with the flow passage, making the process tool-free and user-friendly
2Ease of operation
If a one-touch connection scheme with rotation structure is used, then filter attachment and detachment become easier, but the structure becomes complex with many parts and a complicated passage structure
Solution Approach 1:
The lever is integrated directly with the flow passage structure, merging the operation mechanism and the fluid passage into a single unified component. This eliminates the need for separate rotation structures and reduces the total number of parts while maintaining the one-touch operation functionality
Solution Approach 2:
The lever serves multiple functions simultaneously: it acts as both the operation handle for filter attachment/detachment and as part of the flow passage structure itself. This multi-functionality reduces structural complexity by eliminating redundant components
