Renovation ceiling mat
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional acoustic ceiling tile renovation methods either result in aesthetic issues due to replacement of individual panels or are costly when replacing all panels, as newer panels may have different appearances and replacing all panels is unnecessary.
Innovation Solution
A non-woven fibreglass renovation mat with specific fillers like aluminium trihydrate, calcium carbonate, and binders, which maintains acoustic properties and effectively covers stains with an air porosity of at least 100 l/m2/sec and ΔE≤2, allowing for aesthetic improvement without replacing existing ceiling tiles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If individual stained panels are replaced with identical replacement panels, then the aesthetic appearance of the ceiling is improved, but aesthetic issues arise because newer panels have different appearance than older panels
Solution Approach 1:
The invention extracts only the aesthetic function from the ceiling panels by applying a separate renovation mat layer that contains pigments and fillers for stain masking, while leaving the original acoustic panels in place to maintain their acoustic properties and original appearance characteristics
Solution Approach 2:
The renovation mat serves as an intermediary layer between the viewer and the stained ceiling panels, providing stain coverage and aesthetic improvement without requiring removal or replacement of the original panels, thus avoiding appearance mismatches
2Stability of the object's composition
If all panels are replaced to maintain aesthetic uniformity, then uniform appearance is achieved, but costs increase significantly
Solution Approach 1:
The invention applies partial action by treating only the stained areas with renovation mats rather than replacing all panels, achieving sufficient aesthetic uniformity for compromised areas while avoiding the excessive cost of complete panel replacement
Solution Approach 2:
The renovation mat is a cost-effective, disposable overlay material that provides aesthetic improvement without the high cost of replacing entire ceiling panels, accepting that the mat may need periodic replacement rather than investing in permanent panel replacement
3Illumination intensity
If a renovation mat with high filler content is used to cover stains effectively, then stain coverage improves, but acoustic properties deteriorate
Solution Approach 1:
The invention applies local quality by concentrating filler and pigment content specifically in the renovation mat layer for stain masking, while the underlying acoustic panels retain their original acoustic properties, achieving both aesthetic and acoustic requirements in different layers
Solution Approach 2:
The renovation mat is constructed as a composite material combining fibres, fillers, pigments, and binders in specific proportions to achieve both adequate stain coverage and sufficient acoustic openness, balancing aesthetic and acoustic functions in a single integrated solution
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The renovation mat provides effective stain coverage while maintaining the acoustic and aesthetic properties of existing ceiling tiles, reducing installation costs and minimizing disruption by allowing for aesthetic upgrades without removing old tiles.
Implementation Method 1
Upon curing, the binder forms bonds with the base fibres and fillers to form a fibrous network providing acoustic properties
Implementation Method 2
an air porosity of at least 100 l/m2/sec at 100 Pa

AI summary
A mat for covering at least part of a ceiling made up of individual tiles. The mat renovates (e.g., improves, alters) the appearance of the ceiling. The mat is constructed so as to not impede the acoustical performance of the tiles being covered.
