Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current exterior insulated panel systems require multiple specialized trades for on-site installation, leading to construction challenges, especially in taller buildings, and suffer from high pull-out loads on thermal clips due to rotation, necessitating more fasteners.
Innovation Solution
A thermally separated composite panel assembly comprising a steel panel, a thermal separation layer with sheathing board and spaced thermal blocks, and a plenum with perimeter and interior girts, allowing for off-site construction and reduced fastener requirements through snap-on blocks and continuous strips with sealants, forming a load-bearing wall system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If multiple specialized trades install layers on site, then installation flexibility is maintained, but construction time and complexity increase significantly
Solution Approach 1:
The panel system is pre-assembled off-site with all layers (structural panel, thermal separation layer, plenum, cladding) integrated into a single composite unit before delivery to the construction site. This preliminary assembly eliminates the need for multiple specialized trades to install layers sequentially on-site, dramatically reducing construction time while maintaining installation flexibility through modular panel placement.
2Temperature
If thermal clips are used to attach panels, then thermal separation is achieved, but rotation of clips increases pull-out loads requiring more fasteners
Solution Approach 1:
The thermal separation function is divided into two distinct components: thermal separation blocks that provide thermal breaks between structural and cladding layers, and continuous strips that provide mechanical attachment. This segmentation allows the thermal blocks to resist rotation and pull-out loads independently, eliminating the need for excessive fasteners while maintaining effective thermal separation.
Solution Approach 2:
Continuous strips act as intermediary elements between the structural panel and cladding, distributing attachment loads across multiple points rather than concentrating stress on individual thermal clips. This intermediary mechanism reduces pull-out loads on fasteners while maintaining thermal separation through the blocks.
3Stability of the object's composition
If a rigid structural frame is formed with thermal separation, then structural stability improves, but thermal conductance increases
Solution Approach 1:
The frame structure uses different materials with different thermal properties for different functions: structural members (steel or wood) provide rigidity and stability where needed, while thermal separation blocks (insulating material) are positioned at critical thermal bridge locations to block heat flow. This local differentiation of material properties allows the frame to maintain structural stability while minimizing overall thermal conductance through strategic insulation placement.

AI summary
The thermally separated composite panel assembly includes a steel panel, a thermal separation layer, a plenum and cladding. The plenum is operably attached to the thermal separation layer. The cladding is operably attached to the plenum. The steel panel defines the size of the thermally separated composite panel. The steel panel has an outer perimeter and the outer perimeter of the plenum is in registration therewith. The thermally separated composite panel may have a single window therein or a plurality of windows. A plurality of thermally separated composite panels when used together will form a wall.
