Pivotable Top Cover for Water Purifier Filter Exchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water purification apparatuses face difficulties in filter exchange due to complex coupling and decoupling procedures and limited interior space, making it hard to pivot the filter assembly outside for replacement.
Innovation Solution
A water purification apparatus design featuring a main body with a pivotable lid, holders with O-rings, and a top cover with a spiral protrusion, allowing the filter assembly to be easily rotated and removed for exchange, enabling simple coupling and decoupling without requiring external pivoting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a one-touch fitting adapter with slide plates is used for filter assembly coupling, then the coupling mechanism is automated, but the coupling and decoupling procedure becomes complex and difficult to operate
Solution Approach 1:
The filter assembly is divided into separate components: a filter body and a cap assembly that can be independently handled. The cap assembly acts as a separate tool that users attach to the filter body to facilitate removal, rather than requiring complex integrated mechanisms. This segmentation simplifies the exchange process by making each component manageable and the overall procedure more intuitive.
2Reliability
If the filter assembly is designed with complex coupling mechanisms, then the connection reliability is improved, but the device complexity increases
Solution Approach 1:
The cap assembly serves as an intermediary tool between the user and the filter body. Instead of designing complex integrated coupling mechanisms within the filter assembly itself, the cap assembly acts as a separate mediator that users attach to gain leverage for removal. This intermediary approach maintains simple filter body design while still providing reliable connection and easy release.
3Volume of stationary object
If the interior space of the machinery is limited, then the compactness is improved, but the filter assembly cannot be pivoted outside during exchange
Solution Approach 1:
The cap assembly is extracted as a separate removable component from the filter assembly. Users attach the cap assembly to the filter body, then use this combined tool to leverage the filter body out of its housing. By extracting the cap as a separate element, the system allows filters to be removed from tight spaces without requiring the entire filter assembly to be pivoted outside the machinery, thus maintaining compact interior space while improving accessibility.
