Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing insulated roofing systems face issues such as damage to insulation thickness due to perforation, high cost, thermal bridging, and suboptimal load distribution, which affect thermal resistance and increase construction time and complexity.
Innovation Solution
A roofing system with load-distributing profiles and insulating panels that are directly attached to a support structure, using adhesive and fasteners, and supported by spacer profiles to maintain insulation integrity and facilitate easy installation, reducing the need for wooden battens and allowing for various cladding materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If wooden battens or metal profiles are embedded in insulation boards to support and anchor loads, then the insulation boards can bear loads, but the insulation thickness is reduced and thermal resistance deteriorates
Solution Approach 1:
The system separates the load-bearing function from the insulation function by using distinct components: a support structure for loads and insulating slabs for thermal insulation. This segmentation allows each component to optimize its specific function without compromising the other, eliminating the need to embed structural elements within the insulation material.
Solution Approach 2:
A intermediary layer or interface is introduced between the support structure and the insulating slabs, allowing loads to be distributed through the support structure while preserving the full thickness and thermal properties of the insulation layer. This mediator prevents direct contact between structural elements and insulation material.
2Reliability
If insulating slabs are fixed to support structure using adhesives and dowels, then the insulation is secured, but the insulation thickness is reduced due to perforation and bonding layers
Solution Approach 1:
The fixing mechanism is extracted from the insulation slabs and transferred to the support structure. Instead of perforating and bonding insulation slabs directly, the support structure provides anchoring points that secure the insulation slabs without compromising their thickness or requiring extensive perforation.
Solution Approach 2:
The support structure is pre-configured with anchoring elements and bonding interfaces before insulation slabs are installed. This preliminary preparation allows for secure fixation without requiring post-installation perforation or thick bonding layers that would reduce insulation thickness.
3Strength
If laths or joists are used to support and anchor loads, then loads can be fixed to the roof structure, but the construction complexity and cost increase
Solution Approach 1:
The support structure is designed to perform multiple functions simultaneously: it provides structural support, anchors loads, and facilitates the installation of insulation slabs. This multi-functionality eliminates the need for separate laths or joists, reducing construction complexity while maintaining load distribution capability.
Solution Approach 2:
The functions of load support, load anchoring, and insulation fixation are merged into a single integrated support structure. This consolidation eliminates the need for separate structural elements like laths and joists, simplifying the overall construction process while maintaining structural integrity.
4Ease of manufacture
If a wood layer is added on top of insulation to fix sheet metal elements, then sheet metal can be attached to insulation, but construction cost and time increase
Solution Approach 1:
The support structure serves as an intermediary that directly facilitates the attachment of sheet metal elements to the insulation system. This intermediary interface eliminates the need for separate wood layering, reducing construction time and cost while maintaining attachment capability.
Solution Approach 2:
The support structure is pre-configured with attachment interfaces and bonding capabilities before sheet metal installation. This preliminary preparation allows for direct attachment of sheet metal elements without requiring subsequent wood layering, reducing construction time and material costs.
