Hanging system for an extractor hood
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hanging systems for extractor hoods in high-ceilinged rooms either use unsightly cables or aesthetically unpleasing thick frames that are difficult to handle and transport, as they need to accommodate greater forces and distances while maintaining an attractive appearance.
Innovation Solution
A hanging system featuring hollow encasement profiles with passages for cables and coupling pieces that allow movement, providing the necessary strength while concealing cables and maintaining an aesthetically pleasing appearance by using materials like rubber for flexibility and allowing pivoting or spring-like movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If hanging cables are used to support extractor hoods at large distances from the ceiling, then the system can accommodate high ceilings and allow movement, but the cables are unsightly from an aesthetic point of view
Solution Approach 1:
The hanging cables are nested inside hollow encasement profiles that extend from the frame structure to the ceiling. This nesting conceals the unsightly cables while maintaining their functional ability to support the extractor hood at large distances and accommodate movement.
Solution Approach 2:
Encasement profiles serve as intermediary elements between the hanging cables and the visible frame structure. These profiles hide the cables from view while allowing them to perform their supporting and movement-accommodating functions.
2Strength
If frames with thicker profiles are used to support extractor hoods in high ceilings, then the frame can accommodate greater forces and distances, but the profiles become heavier and more difficult to hang and transport
Solution Approach 1:
The support function is segmented between the frame structure (which provides the visible aesthetic profile) and the hanging cables (which provide the actual strength to accommodate forces). This allows the frame to remain lightweight and easy to handle while the cables, which are not visible, bear the mechanical loads.
Solution Approach 2:
The hanging cables act as flexible elements that can be thin and lightweight yet still accommodate the forces acting on the extractor hood in high ceilings. These cables are concealed within encasement profiles, allowing them to be lightweight without compromising aesthetic appearance.
3Shape
If frames are used to hang extractor hoods, then the appearance is aesthetically pleasing, but the system cannot easily accommodate movement and height adjustment
Solution Approach 1:
The system combines the static aesthetic frame structure with dynamic hanging cables that can move and adjust. The encasement profiles follow the movement of the cables, maintaining the aesthetic appearance while allowing the extractor hood to move and be adjusted in height.
Solution Approach 2:
The encasement profiles are nested on the hanging cables in a way that allows them to move together as a unit. This nesting maintains the continuous aesthetic profile while the entire assembly can move to accommodate changes in position and height.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively supports extractor hoods at large distances from the ceiling, accommodating forces and adjusting height easily while appearing as a continuous, aesthetically pleasing profile, thus combining the advantages of cable systems with the aesthetic benefits of frames.
Implementation Method 1
The coupling piece is made of rubber or another elastic material, so that movement is possible between the encasement profile and the frame structure
