Solution Overview
Problem
Existing shading device receiving elements for buildings face issues with integration into insulating material layers due to dimensional mismatches and differing expansion coefficients, inadequate thermal insulation, unsightly external appearance, and static instability, particularly in passive house construction.
Innovation Solution
A receiving element with a uniform thickness matching the insulation layer, featuring two stiffeners for enhanced stability, allowing integration into the insulation layer without compromising thermal insulation, and enabling wider shading systems with secure fastening using commercially available brackets, while maintaining aesthetic appeal and avoiding thermal bridges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a receiving element is integrated into an insulating material layer, then thermal insulation is improved, but dimensional mismatches and differing expansion coefficients cause integration problems
Solution Approach 1:
The receiving element is designed with adjustable dimensional parameters including variable thickness (5-30cm) and variable width (60-120cm) to match different insulation layer specifications. The material composition can be adjusted to achieve expansion coefficients compatible with common insulation materials like polystyrene and polyurethane foam, resolving the dimensional matching problem while maintaining thermal insulation performance.
Solution Approach 2:
The receiving element employs composite material construction combining insulating materials (polystyrene, polyurethane foam, wood fiber boards) with reinforcement elements (steel profiles, aluminum profiles, wooden beams). This composite structure provides both the thermal insulation properties needed for energy efficiency and the structural strength required for dimensional stability and compatibility with insulation layers.
2Adaptability or versatility
If the receiving element is made thicker to match insulation layer thickness, then integration into passive house construction is improved, but structural stability and load-bearing capacity deteriorate
Solution Approach 1:
The receiving element combines insulating materials with embedded reinforcement structures including steel profiles, aluminum profiles, or wooden beams. This composite construction provides both the necessary thickness (5-30cm) for integration into passive house insulation layers and the structural strength for load-bearing capacity and stability.
Solution Approach 2:
The receiving element incorporates reinforcement elements that extend in multiple dimensions - vertical stiffeners for height, horizontal beams for width, and depth-wise embedding into the insulation layer. This multi-dimensional reinforcement structure provides comprehensive structural support throughout the thickness of the element.
3Ease of operation
If traditional box structures are used for receiving elements, then shading device accommodation is achieved, but unsightly heels remain visible and plaster tearing occurs
Solution Approach 1:
The receiving element features differentiated local qualities with a smooth, aesthetically pleasing external surface suitable for plaster application and visual integration into the building facade. The internal structure contains the cavity for shading device accommodation and reinforcement elements, while the external surface is designed specifically for aesthetic appearance and plaster adhesion without visible heels or protrusions.
Solution Approach 2:
The receiving element merges the functional cavity for shading devices with the aesthetic external surface into a single integrated structure. The smooth external surface is continuous with the building facade, eliminating visible seams or heels, while internally accommodating the shading mechanism through a carefully designed cavity structure.
4Ease of manufacture
If receiving elements are arranged above window or door elements, then integration is simplified, but higher storey height is required and static capacity is insufficient
Solution Approach 1:
The receiving element is designed to be embedded within the insulation layer at the same level as the building facade, rather than protruding above the window or door elements. This repositioning in the vertical dimension eliminates the need for additional storey height while maintaining integration simplicity through form-fit connection with the insulation layer.
5Strength
If metal reinforcements are provided inside the receiving element, then structural stability is improved, but device complexity and assembly effort increase
Solution Approach 1:
The receiving element employs universal reinforcement profiles (steel, aluminum, or wood) that serve multiple functions: providing structural stability, enabling form-fit connection with insulation layers, and supporting shading device accommodation. This multi-functional design reduces device complexity by eliminating the need for separate specialized components for each function.

AI summary
The element has a hollow space (2) or recess provided in its inner side, where the element is designed as a mold (1) and has a material thickness that corresponds to a material thickness of an insulating material layer (8) attached at an outer side of a building (I). The mold is made of insulating material (9) such as polystyrene, polyurethane foam, poroton brick and liapor. An inner lining (6) is connected with a stiffener e.g. metal plate, via connecting units e.g. bolts, wires, screws and reinforcement iron, where the lining is formed of corrosion resistant steel and aluminum plates. An independent claim is also included for an insulating material layer arranged at outer side of a building.
