Table ventilation device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Table ventilation devices face challenges in filter accessibility due to their design, particularly with odor filters positioned downstream of the fan, making it difficult and cumbersome for users to replace filters without additional handling aids.
Innovation Solution
A table ventilation device with a motorized extension means that allows the filter module to be moved from an operating position to a removal position, enabling easy access and replacement of filters, including odor filters, by positioning them above the vapor extraction opening for ergonomic replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the table ventilation device is positioned below the worktop behind the hob, then the device achieves a compact design and proper vapor extraction positioning, but the filters become difficult to access for replacement
Solution Approach 1:
The patent implements a motorized extension means that can dynamically change the position of the filter module between a retracted state (within the device) and an extended state (protruding above the worktop). This dynamic positioning system allows the filters to be easily accessible during maintenance while maintaining a compact integrated design during normal operation, resolving the contradiction between filter accessibility and device compactness.
2Ease of manufacture
If the odor filter is positioned downstream of the fan at the air outlet, then the filter effectively captures odors, but the filter becomes even more difficult to reach and replace
Solution Approach 1:
The patent introduces an intermediary extension means that acts as a mechanical bridge between the filter module and the user. This extension mechanism allows the filter to remain positioned downstream of the fan for effective odor capture while providing a mechanical means to extend the filter above the worktop, making it accessible for replacement without requiring complex disassembly of the device.
3Ease of operation
If the filter module is located 10-20 cm below the appliance upper edge, then the device maintains a sleek appearance, but filter replacement requires reaching through a narrow opening
Solution Approach 1:
The motorized extension means provides dynamic repositioning capability, allowing the filter module to be extended above the appliance upper edge only when needed for maintenance. During normal operation, the filter remains retracted to maintain the sleek appliance profile. This dynamic solution eliminates the need to choose between aesthetic design and maintenance convenience.
