Rotatable Filter Head Assembly Module for Water Purification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water purifying filter assembly modules face difficulties in assembly due to obscured filter assembly heads, require excessive force for screw connections, risk of filter falling during high-pressure water introduction, and potential water leakage, especially when space is limited.
Innovation Solution
A water purifying filter assembly module with a rotatable filter assembly head and movement guide portion that allows for easy alignment and assembly of the filter, incorporating a check valve to prevent leakage and a filter change time indicator to facilitate timely filter replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the water purifying filter is assembled using a screw connection, then the filter can be securely attached to the assembly module, but a larger force is required to assemble the filter
Solution Approach 1:
The attachment mechanism is divided into two functional parts: a protrusion that provides mechanical engagement and a seal that prevents leakage. This segmentation allows the filter to be securely attached without requiring excessive assembly force, as the protrusion-snug fit mechanism naturally guides and secures the filter during assembly.
Solution Approach 2:
The protrusion acts as an intermediary element between the filter and the assembly module head. This intermediary structure facilitates easy assembly by providing a guided path for the filter to engage with the module, eliminating the need for high assembly forces while ensuring secure attachment.
2Ease of operation
If the water purifying filter is caught by a protrusion provided on the assembly module, then the filter can be easily assembled, but the filter may fall down when high-pressure water is introduced
Solution Approach 1:
The protrusion and seal are merged into a unified attachment structure where the seal is positioned to work in conjunction with the protrusion. This combination ensures that when high-pressure water is introduced, the seal prevents the filter from detaching while the protrusion maintains easy assembly capability.
Solution Approach 2:
The seal is designed with a curved surface that matches the contour of the filter interface. This curvature allows the seal to conform to the filter shape, providing reliable sealing and preventing filter detachment under high-pressure water conditions while maintaining ease of assembly.
3Volume of moving object
If the filter assembly head is located at a lower position, then the module structure is compact, but the user cannot see the filter assembly head during assembly
Solution Approach 1:
The filter assembly head is designed with a transparent or translucent portion that allows visual observation from the side or top direction. This dimensional approach to transparency enables the head to remain in a compact lower position while still being visible to the user during assembly operations.
4Productivity
If the water purifying filter is assembled on the assembly module, then the filtration system is complete, but water leakage may occur due to the weight of the filter
Solution Approach 1:
The seal is designed with a curved surface that matches the contour of the filter interface. This curvature allows the seal to conform to the filter shape, providing reliable sealing that prevents water leakage caused by the weight of the filter while maintaining system completeness.
Solution Approach 2:
The seal is made from elastomeric material that combines flexibility with sealing capability. This composite material property allows the seal to deform slightly under the weight of the filter, maintaining intimate contact with the filter interface and preventing water leakage.

AI summary
There is provided a water purifying filter assembly module that a water purifying filter can be easily released from or assembled with. The water purifying filter assembly module may include: a filter assembly head having a water purifying filter assembled on one side thereof, the filter assembly head configured such that water to be filtered flows into the water purifying filter and the water, filtered through the water purifying filter, is discharged to an outside thereof; and a module body having the filter assembly head rotatably provided therein, the water purifying filter being released from or assembled on the filter assembly head as the water purifying filter is aligned and rotates with the filter assembly head.
