Solution Overview

Problem

Existing suspended ceiling systems face challenges in forming reliable, air leakage-resistant seals between ceiling panels and support grids, which are often installed manually on-site, leading to inconsistent results and delayed installation due to the uncontrolled environment and reliance on installer skill.

Innovation Solution

A gasketed ceiling system where resiliently compressible gaskets are pre-attached to ceiling panels in a factory setting, using materials like cross-linked polyethylene foam, ensuring a consistent and effective seal without additional weights or clips, and adhered to the panel edges to form a minimal visible interface.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If gaskets are manually installed in the field during ceiling installation, then the sealing function can be achieved, but installation time increases and sealing quality becomes inconsistent

Engineering Contradiction:
Improvesealing quality consistencyVSAvoidinstallation time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The gasket is pre-attached to the ceiling panel in the factory before shipment, eliminating the need for field installation. This preliminary action ensures consistent sealing quality through controlled factory conditions while reducing on-site installation time and eliminating variability caused by different installers' skills.

Inventive Principle:
Principle #10Preliminary action

2Manufacturing precision

If gaskets are installed in the controlled factory environment, then sealing consistency improves, but additional manufacturing steps are required

Engineering Contradiction:
Improvegasket attachment consistencyVSAvoidmanufacturing process complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The gasket attachment process is merged with the existing ceiling panel fabrication process in the factory. By integrating the gasket application into the inline assembly line, the system achieves consistent sealing quality without adding significant manufacturing complexity, as the gasket is applied during normal production operations.

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If ceiling panel weight is increased to compress the gasket more, then sealing effectiveness improves, but structural load increases

Engineering Contradiction:
Improveair seal effectivenessVSAvoidceiling panel weight
Core Design Contradiction:
ReliabilityVSWeight of moving object

Solution Approach 1:

The gasket material parameters (density, thickness, compressibility) are specifically selected and optimized to achieve effective sealing with the existing ceiling panel weight. By adjusting the gasket's physical properties rather than increasing panel weight, the system maintains air seal effectiveness while avoiding additional structural load.

Inventive Principle:
Principle #35Parameter changes

4Reliability

If additional weights or clips are added to compress the gasket, then sealing reliability improves, but device complexity and installation difficulty increase

Engineering Contradiction:
Improveseal compression consistencyVSAvoidadditional components
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The ceiling panel's own weight is utilized to compress the gasket and create the seal, eliminating the need for additional weights, clips, or springs. The system is designed so that the normal installation process itself provides the necessary compression force, simplifying the overall device and installation procedure.

Inventive Principle:
Principle #25Self-service

AI summary

A suspended ceiling system in one embodiment includes a grid support member and a ceiling panel supported on the member. A resiliently compressible gasket is disposed at the interface between the grid support member and peripheral edge of the panel. The gasket may be fixedly attached to the panel peripheral edge in the factory under controlled conditions before shipment to the ceiling installation site. In one embodiment, the gasket may be adhesively attached to the panel. Mounting the ceiling panel on the grid support member compresses the gasket to preferably form a minimally visible air leakage resistant seal between the air plenum space above the ceiling panels and the occupied space below. This retards air exchange between the spaces which enhances heating/cooling efficiency, noise reduction and allows formation of pressurized clean rooms.
