Solution Overview

Problem

Conventional ceiling substructures face challenges with imprecise and complex installation due to the need for cutting basic profile elements to size for U-shaped edge profiles, leading to time-consuming and inaccurate installations.

Innovation Solution

A ceiling substructure design featuring an L-shaped edge profile element with an inwardly angled second leg and a distal section angled outward, allowing basic profile elements to be easily positioned and building boards to be attached at the same level, eliminating the height offset between support and base profile elements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If U-shaped edge profiles are used, then the edge profile can be mounted on the wall, but the basic profile elements have to be cut to size which is time-consuming and results in inaccuracy

Engineering Contradiction:
Improveinstallation accuracyVSAvoidinstallation time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The second leg of the L-shaped edge profile is segmented into three distinct sections: an inwardly angled section, a parallel section, and a distal outwardly angled section. This segmentation allows each section to serve a specific function in positioning and supporting the basic profile elements, eliminating the need for cutting while maintaining precise alignment and height positioning.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If conventional L-shaped and U-shaped edge profiles are used, then the edge profile can be mounted on the wall, but the installation of the ceiling substructure becomes imprecise and complex

Engineering Contradiction:
Improveease of installationVSAvoidinstallation precision
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The inwardly angled section of the second leg acts as an intermediary element that facilitates the connection between the wall-mounted first leg and the basic profile elements. This intermediate section provides a convenient interface for positioning and securing the basic profiles without requiring complex cutting or adjustment operations.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The edge profile utilizes multiple spatial dimensions through the three-dimensional configuration of the second leg with its angled and parallel sections. This multi-dimensional structure provides inherent positioning in both horizontal and vertical directions, simplifying the installation process while maintaining high precision without requiring additional adjustment steps.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
