Two-Frame Extractor Hood Mounting for One-Person Cabinet Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for mounting kitchen extractor hoods between hanging cabinets are cumbersome and require multiple persons for installation, as they do not facilitate quick and easy alignment with the cabinets' profile, leading to prolonged installation times.
Innovation Solution
A system comprising a first frame with adjustable projections and a second frame, allowing for precise positioning of the extraction motor unit and hood casing, enabling single-person installation and coplanar alignment with hanging cabinets without the need for screws and bolts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a first frame is secured to the wall and the hood casing is fixed using screws and bolts, then the hood can be mounted securely, but the installation requires at least two persons and takes a very long time
Solution Approach 1:
The mounting system is divided into two separate frames: a first frame secured to the wall for mounting the extraction motor unit, and a second frame connected to the first frame for mounting the hood casing. This segmentation allows independent positioning and fixation of each component, enabling one person to perform the installation without requiring another person to hold the hood in position.
Solution Approach 2:
The first frame is pre-secured to the wall with adjustable projections that can be positioned at different depths. The second frame is then connected to the first frame with fixation elements. This preliminary arrangement of the frame structure before mounting the actual hood components simplifies the installation process and reduces the time required.
2Shape
If the hood is mounted between hanging cabinets with coplanar alignment, then aesthetic requirements are met, but the positioning becomes complex and time-consuming
Solution Approach 1:
The first frame includes adjustable projections with adjustable depth, allowing the position of the extraction motor unit to be adapted. The second frame is connected to the first frame and can be positioned to ensure coplanar alignment with the hanging cabinets. This dynamic adjustability simplifies achieving the required aesthetic alignment without complex positioning procedures.
3Reliability
If traditional screw and bolt fixation is used, then secure mounting is achieved, but the device complexity and number of components increase
Solution Approach 1:
The patent introduces a second frame as an intermediary component between the wall-mounted first frame and the hood casing. This second frame serves as a mediator that simplifies the mounting process by providing a pre-positioned structure for attaching the hood casing, reducing the need for multiple screws and bolts directly between the wall and the hood.

AI summary
An assembly for mounting a kitchen extractor hood to a wall can include the kitchen extractor hood and a mounting system. The kitchen extractor hood can include: an extraction motor unit; filter devices; a channel to eject the extracted air; and a casing. The mounting system can include: a first frame secured to the wall, wherein the first frame is configured to support the extraction motor unit, wherein the first frame includes right-angled elements whose longer vertical sides are configured to be fixed to the wall by expansion means. The right-angled elements can include protruding overhanging shorter sides that form a bracket configured to support the extraction motor unit. The mounting system can further include: a second frame fixed to the first frame, wherein the second frame is configured to receive and hold the casing based on a position of the extraction motor unit on the bracket.
