Solution Overview

Problem

Existing ceiling systems face challenges in achieving a good quality finish and ease of installation, particularly due to the visibility of supporting structures and potential distortion of flexible ceiling panels caused by relative movement of elongate carriers.

Innovation Solution

A ceiling system design utilizing elongate carriers supported by suspension hangers, with elongate beams connected by brackets via push-fit connections, such as snap-fit or friction-fit, to stabilize the carriers and panels, allowing for tool-free installation and improved stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If elongate carriers are used to support ceiling panels, then the number of connections to the structure is reduced, but the stability of the carriers relative to each other deteriorates

Engineering Contradiction:
Improvenumber of connectionsVSAvoidrelative position stability
Core Design Contradiction:
Device complexityVSStability of the object's composition

Solution Approach 1:

The patent combines multiple elongate carriers into a single integrated unit by connecting them together laterally. This merging approach maintains the reduction in structural connections while internally stabilizing the carriers relative to each other through direct carrier-to-carrier connections, resolving the contradiction between reduced complexity and maintained stability.

Inventive Principle:
Principle #5Merging (Combining)

2Ease of operation

If flexible ceiling panels are used, then ease of installation is improved, but distortion occurs due to carrier movement

Engineering Contradiction:
Improveinstallation easeVSAvoidpanel flatness
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The patent applies preliminary anti-action by pre-stiffening the elongate carriers through their interconnection before the flexible ceiling panels are installed. This preventive measure counteracts the potential distortion that would occur during installation and use, allowing the flexible panels to be easily installed without subsequent distortion, thus resolving the contradiction between installation ease and panel flatness.

Inventive Principle:
Principle #9Preliminary anti-action

3Productivity

If tool-free push-fit connections are used, then installation speed is improved, but connection strength deteriorates

Engineering Contradiction:
Improveinstallation speedVSAvoidconnection strength
Core Design Contradiction:
ProductivityVSStrength

Solution Approach 1:

The patent employs curved or tapered connection surfaces in the push-fit joints between elongate carriers. These curved geometries create friction-based mechanical interlocking that provides sufficient connection strength while maintaining the tool-free installation advantage. The curved surfaces allow for easy insertion through elastic deformation while preventing withdrawal through friction, resolving the contradiction between installation speed and connection strength.

Inventive Principle:
Principle #14Spheroidality (Curvature)
