Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flat roof insulating systems face challenges in balancing ease of manufacturing, thermal resistance, fire safety, and secure attachment, particularly on horizontal or slightly sloped roofs, where traditional methods often compromise on one or more of these aspects.
Innovation Solution
A flat roof insulating system comprising a mineral wool panel with a facing and a hook and loop fastening system, where the mineral wool panel is secured to a weatherproof membrane using the hook and loop system, providing a combination of high thermal and fire resistance with ease of installation and manufacturing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional anchoring methods are used to secure the weatherproof membrane, then attachment reliability is improved, but device complexity and ease of installation deteriorate
Solution Approach 1:
The patent replaces the traditional mechanical anchoring system (screws, clips, or other fasteners) with a chemical bonding system using adhesive. The adhesive is applied to the upper surface of the mineral wool insulation panel to bond the weatherproof membrane, eliminating the need for complex mechanical anchoring components and simplifying the overall attachment system while maintaining reliability
Solution Approach 2:
The invention extracts and removes the anchoring system from the flat roof insulating system, retaining only the adhesive bonding mechanism. This extraction simplifies the device by eliminating unnecessary anchoring components and reducing overall system complexity while still achieving secure attachment of the weatherproof membrane
2Temperature
If mineral wool binder content is increased to improve thermal insulation, then thermal resistance is improved, but manufacturing complexity and formaldehyde control worsen
Solution Approach 1:
The patent specifies precise parameter ranges for the mineral wool binder content (between 2% and 7% by weight of the total panel weight) and formaldehyde levels (less than 5 ppm). By controlling these parameters within defined ranges, the invention achieves optimal thermal resistance while maintaining ease of manufacture and meeting formaldehyde emission standards
Solution Approach 2:
The invention applies local quality control by specifying that the binder content and formaldehyde levels should be controlled at specific locations and stages during manufacturing. The facing layer is applied to the upper surface with specific binder characteristics, allowing optimized thermal performance in the insulation core while controlling formaldehyde emissions at the surface level
3Object-affected harmful factors
If a facing is added to the mineral wool panel to protect against water ingress, then protection against harmful factors is improved, but device complexity and manufacturing steps worsen
Solution Approach 1:
The patent merges the facing layer with the mineral wool insulation panel into a single integrated component. The facing is applied to the upper surface of the mineral wool blanket during the manufacturing process, and both layers are cured together in a single operation. This merging protects against water ingress while avoiding the complexity of assembling separate facing and insulation components
Solution Approach 2:
The facing is applied to the mineral wool blanket before the final curing step in the manufacturing process. This preliminary action ensures that the facing is securely bonded to the insulation panel during production, providing immediate protection against water ingress without requiring additional assembly steps after manufacturing
