Suspended Ceiling Tile Edge Grooves Prevent Displacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing suspended ceilings face issues with ceiling tiles being displaced due to sudden air pressure changes, cleaning forces, and wind uplift, and current solutions like spring arrangements or hold-down clips are cumbersome to install and can damage the tiles.
Innovation Solution
The ceiling tile design incorporates side-edge portions with grooves and flanges that engage with the grid of profiles from both above and below, providing a clamping action to prevent vertical and lateral displacement without the need for external locking devices, allowing for easier installation and demounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If spring arrangements or hold-down clips are used to prevent ceiling tile displacement, then the ceiling tile stability is improved, but the device complexity and installation time increase
Solution Approach 1:
The invention extracts the displacement prevention function from separate external locking devices and integrates it directly into the ceiling tile structure through grooves and engagement portions. This eliminates the need for spring arrangements or hold-down clips, resolving the contradiction by removing the complex external components while maintaining the stability function within the tile itself.
Solution Approach 2:
The ceiling tile is designed with self-locking engagement portions and grooves that automatically prevent displacement when the tile is installed in the grid. The tile serves its own stabilization function without requiring external locking devices, thereby simplifying the overall system while maintaining reliability.
2Reliability
If spring arrangements or hold-down clips are installed, then ceiling tile displacement is prevented, but the installation time and labor requirements increase
Solution Approach 1:
By removing the need for separate locking devices and integrating displacement prevention directly into the tile structure, the installation process is simplified to only require placing the tile into the grid position, significantly reducing installation time while maintaining stability.
Solution Approach 2:
The self-locking grooves and engagement portions automatically secure the tile upon installation without requiring additional steps for attaching locking devices, thereby eliminating the time-consuming installation process associated with spring arrangements or clips.
3Reliability
If external locking devices are used, then ceiling tile displacement is prevented, but the manufacturing process complexity increases
Solution Approach 1:
The invention removes the need for separate locking device manufacturing and assembly processes. The displacement prevention features are integrated directly into the ceiling tile manufacturing process, simplifying the overall manufacturing workflow while ensuring tile stability.
Solution Approach 2:
The grooves and engagement portions are combined as integral parts of the ceiling tile structure, manufactured together in a single process rather than requiring separate production and assembly of locking devices, thereby simplifying the manufacturing process.
4Reliability
If external locking devices are installed, then ceiling tile displacement is prevented, but the ceiling tile may be damaged due to its porous and fragile nature
Solution Approach 1:
By eliminating external locking devices that require drilling, screwing, or clipping operations, the invention removes the source of potential damage to porous and fragile ceiling tiles. The integrated grooves and engagement portions are designed to work with the tile material without causing harm.
Solution Approach 2:
The ceiling tile's own structure provides the displacement prevention function through its grooves and engagement portions, avoiding the need for external devices that could damage the tile during installation or use.

Function Achieved in This Case
This design effectively prevents involuntary displacements of ceiling tiles, simplifies the mounting process, reduces the need for additional hardware, and allows for easier access to the plenum space by eliminating the requirement for separate entrance chambers.
Implementation Method 1
each side-edge portion of the first pair comprises an upper engagement surface and each side-edge portion of the second pair comprises a lower engagement surface... A portion of the grid of profiles may engage from below with the first pair of side-edge portions... while another portion of the grid of profiles may engage from above with the second side-edge portions
