Roller Shutter Box Composite Profile Thermal Insulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing roller shutter boxes for windows and doors suffer from poor thermal insulation due to cold bridges and inadequate force transmission, with previous solutions failing to provide a robust and efficient mounting system.
Innovation Solution
A box design featuring a composite profile with a metallic inner and outer profile connected via an insulating profile, along with a lower composite profile connected via a C-shaped connecting profile, incorporating an insulating element and spacer elements to prevent cold bridges, and a sealing profile for moisture protection, allowing for direct or gap-based insulating arrangements and secure mounting on window or door frames.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a roller shutter box is mounted above a window frame with thermal insulation layers, then thermal separation is achieved, but cold bridges remain due to offset arrangement and the connection is loose unsuitable for force transmission
Solution Approach 1:
The roller shutter box employs a composite profile structure combining metallic components (for structural strength and force transmission) with plastic insulating components (for thermal insulation). The profile integrates an insulating strip made of plastic material positioned between metallic profile parts, creating a composite structure that simultaneously achieves both thermal insulation and mechanical stability without cold bridges.
2Ease of manufacture
If profiles are combined to form a box with hollow profiles connected via separable plug connections, then assembly is simplified, but thermal insulation remains poor
Solution Approach 1:
The box structure utilizes composite profiles where plastic insulating strips are integrally combined with metallic profile sections. This composite construction maintains the ease of assembly through modular profile connections while eliminating thermal bridges by ensuring continuous plastic insulation throughout the profile joints, preventing heat transfer paths that would occur with simple metallic connections.
3Temperature
If a roller shutter box with composite profile and insulating element is designed, then thermal insulation is improved, but the structure becomes more complex
Solution Approach 1:
The patent merges the insulating element with the profile structure itself, where the plastic insulating strip is an integral part of the composite profile rather than a separate component. This integration combines the structural function and thermal insulation function into a single unified element, achieving good thermal insulation without significantly increasing structural complexity or the number of separate parts.

AI summary
A box (1) for housing a roller shutter or sunshade comprises an upper composite profile (2) with a metallic outer profile (3) and a metallic inner profile (4), which are connected to each other via at least one insulating profile (5), and a lower composite profile (12) which is connected to the upper composite profile (2) on an outer side via a connecting profile (6), wherein at least one insulating element (7) is provided inside the box (1), which is arranged at least partially on an inner side of the insulating profile (5). This allows the box (1) to be constructed modularly with high thermal insulation.
