PET Felt Ceiling Tile Retrofit for Stick-Built Grids
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modernizing large spaces with polyethylene terephthalate (PET) Felt acoustic solutions is costly due to the need for replacing existing stick-built grid systems, which are not compatible with PET Felt.
Innovation Solution
A PET felt tile system designed to fit within existing stick-built grid systems without the need for adhesives, clips, or hangers, utilizing a tile with slots and a blade configuration that allows secure placement without damaging the grid system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing stick-built grid systems are replaced with new hangers to support PET Felt, then acoustic performance and interior design compatibility are improved, but modernization costs increase significantly
Solution Approach 1:
The patent introduces an intermediary component system consisting of a frame with cross members and clips that act as a mediator between the existing stick-built grid system and the PET Felt acoustic panel. This intermediary structure allows the new acoustic material to be supported by the old grid system without requiring replacement of the entire hanger system, thus improving acoustic performance while controlling modernization costs.
Solution Approach 2:
The frame structure with cross members and clips serves multiple functions: it provides structural support for the PET Felt, interfaces with the existing stick-built grid system, and enables easy installation and removal. This multi-functional design allows the system to work with existing infrastructure while providing modern acoustic solutions.
2Reliability
If PET Felt is used in existing stick-built grid systems, then acoustic control and interior design appeal are improved, but compatibility with the grid system deteriorates
Solution Approach 1:
The patent divides the support system into segmented components: a frame structure with cross members spaced at specific intervals, and individual clips attached to these cross members. This segmentation allows the system to adapt to the existing stick-built grid pattern while providing uniform support for the PET Felt acoustic panel throughout the ceiling area.
Solution Approach 2:
The frame and clip assembly serves as an intermediary that translates the structural characteristics of the existing stick-built grid system into appropriate support points for the PET Felt panel, enabling compatibility between the two otherwise incompatible systems.
3Ease of operation
If PET Felt is installed without adhesives, clips, or hangers, then installation simplicity and grid system preservation are improved, but secure placement of the tile may deteriorate
Solution Approach 1:
The patent extracts the fastening function from traditional adhesives, clips, or hangers and integrates it into the frame structure itself. The clips are attached to the cross members and directly engage with the PET Felt panel, providing secure placement without requiring separate adhesives or additional fastening components, thus maintaining installation simplicity while ensuring security.
