False Ceiling Assembly Rigidifying Means
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing false ceiling assemblies for exterior applications require supplementary stiff substructures to resist upward loads like wind, limiting panel span and manufacturer control, and necessitating custom designs by installers.
Innovation Solution
A modular false ceiling assembly with a rigidifying means interposed between the panel carrier and suspension device, featuring an I-shaped profile with U-shaped mounting and a length-adjustable, rotatable tubular suspension device, eliminating the need for a separate stiff substructure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a supplementary stiff substructure is used to resist upward loads, then the rigidity and strength of the ceiling assembly is improved, but the device complexity and installation difficulty increase
Solution Approach 1:
The patent combines the stiffening function directly into the suspension device by incorporating a stiffening element within the suspension device structure. This integration eliminates the need for a separate supplementary substructure while maintaining the required rigidity to resist upward loads such as wind forces on exterior ceilings.
Solution Approach 2:
The patent extracts the stiffening function from the concept of a separate supplementary substructure and embeds it within the suspension device itself. This extraction allows the suspension device to independently provide both suspension and stiffening functions, reducing overall system complexity.
2Strength
If a supplementary stiff substructure is used, then the ability to resist upward forces is improved, but manufacturer control over installation and materials is lost
Solution Approach 1:
By merging the stiffening function into the suspension device, the manufacturer maintains control over both the suspension and stiffening components as a single integrated product. This eliminates the need for installers to design and source separate substructures, preserving manufacturer control over installation procedures and material specifications.
3Strength
If panel span is limited to achieve required rigidity, then the strength is improved, but the area coverage efficiency decreases
Solution Approach 1:
The stiffening element is pre-integrated into the suspension device structure, providing rigidity reinforcement before the ceiling panels are installed. This preliminary stiffening allows for larger panel spans without compromising structural integrity, as the rigidity is already in place to support larger areas.
4Adaptability or versatility
If custom substructures are designed by installers, then the adaptability to specific buildings is improved, but the ease of manufacture and standardization decreases
Solution Approach 1:
The suspension device is designed with universal applicability through the integrated stiffening element, allowing it to function as both a suspension and stiffening component across different building types. This multi-functionality eliminates the need for custom installer-designed substructures while maintaining adaptability through standardized components that can be configured for various applications.
