Domestic hood
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing domestic hoods require users to manually or tool-aidedly disconnect electric lighting components from the power source for filter unit access, posing safety risks and inefficiency.
Innovation Solution
The hood design allows for the electric disconnection of lighting means from the power circuit by a simple pull force, enabling safe and easy removal without direct interaction with electrical connections, using movable contact terminals and magnetic fixing means to ensure insulation during removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the lighting means are made removable for filter access, then ease of filter maintenance is improved, but user safety deteriorates due to exposure to electric connections
Solution Approach 1:
The patent combines the lighting means assembly with the filter unit into a single removable module. When the filter unit is removed for maintenance, the lighting means are automatically removed as well, eliminating the need for separate electrical disconnection steps and ensuring user safety while maintaining ease of filter access
Solution Approach 2:
The lighting means are integrated as part of the filter unit assembly rather than being separate components. This segmentation allows the entire assembly to be removed as one unit, automatically disconnecting electrical connections when the filter is accessed for maintenance
2Ease of operation
If the lighting means are individually disassembled for removal, then ease of removal is improved, but device complexity increases due to multiple components
Solution Approach 1:
The shield, lighting devices, and support structure are merged into a single integrated assembly that moves as one unit. This allows the lighting means to be removed in a single step without requiring disassembly of individual components, simplifying the removal process while maintaining structural integrity
Solution Approach 2:
The lighting means assembly is designed with movable elements that allow it to be easily detached from the hood frame as a complete unit. The assembly can transition between fixed and movable states, enabling simple removal without manual disassembly of individual components

AI summary
The present disclosure relates to a hood (1) for domestic use, which comprises a support frame (10) with a power input (11), a motor fan unit (20) located within said support frame (10), lighting means (30), fixing means (40) for removably fixing said lighting means (30) to said support frame (10), and electric connection means (60) for electrically connecting said lighting means (30) to said power input (11). The hood is characterized in that said lighting means (30) comprise an enclosure (33) that defines a seat (33a) containing a plate (32) having a plurality of LEDs (31), and are movable relative to said support frame (10) between a first position, in which said electric connection means (60) electrically connect said lighting means (30) to said power input (11) and a second position, in which said lighting means (30) are electrically disconnected from said power input (11), wherein said electric connection means (60) are configured to electrically disconnect said lighting means (30) from said power input (11) directly, once said lighting means (30) have moved from said first position to said second position.
