Extractor Hood Filter with Pivoting Attachment for Simplified Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complex removal process of filter elements in extractor hoods makes it difficult to detach and replace them efficiently, requiring safety devices and leverage, which complicates the filtration maintenance.
Innovation Solution
A filter device with a pivoting mechanism that uses a profile rail and connecting elements for secure attachment, allowing for easy attachment and detachment of filter elements without the need for leverage, utilizing a snap connection for haptic feedback and secure hold, and a bearing pin for connection to the extractor hood.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a securing device with retractable pins and fixed tabs is used to prevent the filter element from falling, then the filter element is securely held in place, but the removal procedure becomes complex requiring leverage and multiple steps
Solution Approach 1:
The filter element is divided into a frame portion and a filter mat portion that can be separated. The frame with integrated tabs is retained in the range hood while the filter mat can be easily removed and replaced independently, simplifying the maintenance process.
Solution Approach 2:
The filter mat is extracted as a separate removable component from the filter element assembly. This allows the filter mat to be easily taken out for cleaning or replacement without manipulating the entire filter element or securing mechanisms.
2Stability of the object's composition
If the filter element is designed with integrated tabs and retractable pins for secure mounting, then the filter element remains stable during operation, but the detachment process requires prying and leverage
Solution Approach 1:
The filter element is segmented into a permanent frame structure with integrated tabs and a separate filter mat. The frame remains mounted in the range hood providing stability, while the filter mat can be independently removed and reattached without complex mechanisms.
Solution Approach 2:
Instead of designing the filter element to be permanently secured with complex release mechanisms, the invention inverts the approach by making the filter mat removable while the frame remains fixed. This simplifies the system by eliminating the need for retractable pins and leverage-based release mechanisms.
