Solution Overview

Problem

Existing false ceiling systems do not allow precise control of air diffusion on the outskirts of a room and are not aesthetically pleasing due to the presence of air suction grids.

Innovation Solution

A hooking profile with two wings connected by a horizontal connecting wall, where one wing allows fixing to the wall and the other wing has a harpoon blockage end, defining a slot for air passage that is open along the connecting wall, allowing air to circulate between the plenum and the room without visible obstructions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If traditional ceiling panels with integrated LED modules are used, then aesthetic appearance is improved, but repairability and component replacement difficulty worsen

Engineering Contradiction:
Improveaesthetic appearanceVSAvoidrepairability
Core Design Contradiction:
ShapeVSEase of repair

Solution Approach 1:

The ceiling panel is divided into separate functional modules: a decorative ceiling panel, a separate LED lighting module, and a fixing profile. This segmentation allows the LED module to be independently replaced or repaired without damaging the aesthetic ceiling panel, resolving the contradiction between maintaining aesthetic appearance and enabling easy repair.

Inventive Principle:
Principle #1Segmentation

2Ease of repair

If ceiling panels are made modular with separate LED modules, then repairability is improved, but device complexity increases

Engineering Contradiction:
Improvecomponent replacementVSAvoidassembly complexity
Core Design Contradiction:
Ease of repairVSDevice complexity

Solution Approach 1:

The fixing profile integrates multiple functions into a single component: it provides mechanical attachment for the LED module, electrical connection through integrated contacts, and structural support. This merging simplifies the overall assembly by reducing the number of separate parts and connection steps, thereby improving repairability without significantly increasing device complexity.

Inventive Principle:
Principle #5Merging (Combining)

3Temperature

If air passages are added to fixing profiles, then heat dissipation is improved, but manufacturing complexity increases

Engineering Contradiction:
Improveheat dissipationVSAvoidmanufacturing complexity
Core Design Contradiction:
TemperatureVSEase of manufacture

Solution Approach 1:

The fixing profile incorporates air passages or porous structures that allow air flow through the profile for heat dissipation. These passages are integrated into the profile's geometry during manufacturing, enabling passive cooling without adding complex active cooling systems, thus improving heat dissipation while maintaining ease of manufacture.

Inventive Principle:
Principle #31Porous materials

AI summary

The invention concerns an attachment profile member (6a, 6b) for attaching a fabric for producing a stretched ceiling in a room to be treated, the attachment profile member comprising at least two wings (61, 63) interconnected by a connecting wall (62), said wings being arranged with respect to each other such that they define a slot (22), said profile member being characterised in that it comprises at least one passage opening (19) arranged with the slot to allow air to pass through said profile member. The invention also concerns a ceiling assembly that allows air to flow inside a room to be treated, comprising a stretched fabric extending between the walls of the room to be treated (1) and attached to said walls by means of attachment profile members, at least one of the attachment profile members being an attachment profile member (6a, 6b) that allows air to pass between the plenum chamber and the room to be treated.
