Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If PIV panels with thin barrier envelopes are used to achieve low thermal conductivity, then thermal insulation performance is improved, but the panels become fragile and sensitive to compressive or bending forces
Solution Approach 1:
The system divides the insulation function into separate components: the PIV panels provide thermal insulation while the H-section support profile provides mechanical support. This segmentation allows each component to be optimized for its specific function without compromise.
Solution Approach 2:
The H-section support profile acts as an intermediary between the wall and the PIV panels, bearing the mechanical loads and transferring them to the wall, thereby protecting the fragile barrier envelope from compressive and bending forces.
2Loss of energy
If large-sized PIV panels are used to reduce the number of joints and improve thermal performance, then thermal insulation performance is improved, but the complexity of ensuring airtightness and minimizing thermal bridges at junctions increases
Solution Approach 1:
The H-section support profile serves multiple functions simultaneously: it provides mechanical support for the panels, ensures airtightness at junctions through its sealing lips, minimizes thermal bridges with its low thermal conductivity material, and simplifies assembly with its standardized design.
3Loss of energy
If complex H-section support profiles are used to minimize thermal bridges and ensure airtightness, then thermal insulation performance is improved, but the complexity of the assembly process and adjustment flexibility decreases
Solution Approach 1:
The support profile incorporates adjustable elements such as movable sealing lips and adaptable bracing device positions, allowing the system to be adjusted during assembly to accommodate manufacturing tolerances and site conditions while maintaining thermal performance.

AI summary
The system for lining a wall can incorporate a layer of vacuum insulated panels (3) at a supporting profiled section (10) having an H-shaped section . An anchoring device (15) rigidly connected to the front branch (10b) of this profiled section (10) serves to attach the rear end (20a) of one or a plurality of spacing devices (20). The latter have a front end (20b) provided with a holding element (40) connecting to the profiled sections (5) of the secondary framework of the system. The profiled section (10), which has, on the rear branch (10a) of same, a bearing face that can be attached to the wall, makes it possible to take up the bearing forces transmitted from an outer cladding to each of the devices (20). During assembly, the spacing element (30) of a device (20) can be moved in translation and blocked by one of the holding element (40) and an opposing attachment member (22) in contact with the anchoring device (15).
