Hanger profile and ceiling assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing false ceiling systems do not allow precise control of air diffusion at the periphery of a room and often incorporate visible air inlet grilles, which are aesthetically detrimental and obstruct air circulation between the plenum and the room.
Innovation Solution
A hanger profile for stretched ceilings with strategically positioned openings on its wings and connecting sides, allowing unobstructed airflow between the plenum and the room, eliminating the need for visible grilles while enabling precise air diffusion control through the design of angled wings and deflector mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a closed flexible blade is used to lock the canvas hook in the central core of the profile, then the canvas is securely held, but air circulation between the plenum and the room is blocked
Solution Approach 1:
The profile is divided into distinct functional zones: a central core for canvas holding and peripheral regions for air circulation. The flexible blade is positioned only in the central core area, while the connecting sides and wing edges remain open to allow air passage, thus segmenting the profile functions to resolve the contradiction between secure canvas holding and air circulation.
Solution Approach 2:
Different parts of the profile are given different properties: the central core has a closed flexible blade for secure canvas holding, while the connecting sides and peripheral areas have open structures optimized for air circulation. This local differentiation allows each region to perform its specific function without interfering with the other.
2Productivity
If air inlet grilles are used to enable air circulation, then air can pass through the room, but the aesthetics of the room is deteriorated due to visible grilles
Solution Approach 1:
The air circulation function is extracted from traditional visible grilles and integrated into the hanger profile structure itself. The profile's connecting sides and wing edges serve dual purposes: structural support for the canvas and aesthetic air passageways, eliminating the need for separate grille components and improving overall appearance.
Solution Approach 2:
The structural function of the hanger profile and the air circulation function are merged into a single integrated component. The profile simultaneously holds the canvas and provides aesthetic air passageways through its design, combining what were previously separate functions into one unified element.
3Reliability
If the central core is completely blocked by the flexible blade for hook passage, then the hook is securely retained, but air circulation is prevented between the plenum and the room
Solution Approach 1:
The profile is segmented into a central core region for hook retention and peripheral regions for air circulation. The flexible blade is confined to the central core, while the connecting sides and wing edges remain open, allowing air to circulate around the central blocked area through multiple pathways.
Solution Approach 2:
Air circulation is redirected from a linear path through the central core to a three-dimensional flow pattern around the periphery of the profile. The connecting sides and wing edges create multiple air passageways that allow air to flow around the blocked central core region, utilizing spatial dimensions to bypass the obstruction.

AI summary
A canvas hanger profile for making a stretched ceiling in a room to be conditioned, the hanger profile comprising at least two wings connected together by a connecting lining, one of the wings being arranged to allow the fastening of the hanger profile on a wall of the room to be conditioned, a second wing, which constitutes a canvas hanger wing, being provided with a blocking end of a canvas hook, wherein the connecting lining and the hanger wing are arranged to define together an unclosed air passage slot through the profile and are delimited by the blocking end of the hanger wing hook, the profile having at least one through opening arranged to allow air to pass through said profile from or towards the slot.
