Solution Overview

Problem

Existing false wall slabs face challenges such as frame deformation due to light structure, high cost of prestress solutions, unsightly wide T-shaped support elements, and difficult gluing methods that hinder easy sheet removal and adaptation.

Innovation Solution

A false wall slab design featuring a frame with recesses and deformable spikes for secure, glue-free attachment, allowing easy sheet replacement and hiding frame shadows, using aluminum alloy profiles with triangular cross-sections and removable fixing clips.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a light structure frame is used, then ease of manufacture and cost are improved, but resistance to bending and frame stability deteriorate

Engineering Contradiction:
Improveease of manufactureVSAvoidresistance to bending
Core Design Contradiction:
Ease of manufactureVSStrength

Solution Approach 1:

The frame is divided into multiple profiles that are abuttingly assembled together to form the complete frame structure. Each profile is a separate component that can be manufactured independently and then assembled, allowing for easier manufacturing while maintaining structural integrity through the collective arrangement of multiple segments.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The frame combines aluminum alloy profiles with specific geometric cross-sections (inverted T-shape or L-shape) to achieve optimal strength-to-weight ratio. The composite structure of the profile design provides enhanced resistance to bending forces while keeping the overall frame lightweight and easy to manufacture.

Inventive Principle:
Principle #40Composite materials

2Strength

If conventional gluing method is used, then sheet attachment strength is improved, but ease of operation and adaptability deteriorate

Engineering Contradiction:
Improveattachment strengthVSAvoidease of sheet removal
Core Design Contradiction:
StrengthVSEase of operation

Solution Approach 1:

The attachment system transitions from a permanent static bond (gluing) to a dynamic, reversible mechanical connection. The夹持 element can grip the sheet firmly during use but allows for easy release and repositioning, enabling the sheet to be removed and adapted to different frames or repositioned as needed.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

A mechanical夹持 element serves as an intermediary between the frame and the sheet, replacing the direct chemical bond of gluing. This intermediary component provides the attachment function while enabling easy operation, as the夹持 element can be independently adjusted, released, and repositioned without damaging the sheet or frame.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Strength

If wide T-shaped support elements are used, then frame stability and resistance to tensile forces are improved, but aesthetic appearance deteriorates

Engineering Contradiction:
Improveresistance to tensile forcesVSAvoidaesthetic appearance
Core Design Contradiction:
StrengthVSShape

Solution Approach 1:

The frame profiles have different cross-sectional shapes (inverted T-shape or L-shape) optimized for specific structural requirements at different locations. The local geometry provides enhanced resistance to tensile forces where needed while maintaining a sleek, narrow profile that does not compromise aesthetic appearance when installed.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

Instead of using wide T-shaped support elements that protrude outward, the invention inverts the support structure by using profiles with inverted T-shaped or L-shaped cross-sections that provide structural strength while maintaining a narrow external profile. The support function is achieved through the internal geometry and abutting arrangement rather than external width.

Inventive Principle:
Principle #13The other way round (Inversion)

AI summary

The invention relates to a suspended ceiling tile (1), comprising a frame (2) made from butted profiles (3) and a sheet (4) fixed and stretched over said frame (2), each profile (3) having an upper wall (31), a side wall (32) originating from one of the ends of said upper wall (31) and a reinforcing wall (33) joining the free ends of the upper and side walls (31, 32) so that each profile (3) has a cross-section in the general shape of a triangle, said tile (1) being notable in that it has a fixing clip (6) and in that the upper wall (31) is provided with at least one housing (36) adapted to cooperate removably with said fixing clip (6) to fix the sheet (4) stretched over said frame (2) by holding it tight in said housing (36) by the fixing clip (6).
