Insulating Body Integrating Fastening Projections and Guiding Contours
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multi-shell construction elements, such as doors and windows, require multiple components and assembly steps due to the need for separate insulating stays and additional guides for fitting parts, which complicates the configuration and assembly process.
Innovation Solution
An insulating body with at least two fastening projections and a hollow chamber with an inner guiding contour that secures profiled section elements against tilting and eliminates the need for separate components by integrating fitting parts, featuring a monolithic design with optional outward receptacles and recesses for additional elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate insulating stays and guides are used, then the profiled section elements are secured against tilting and fitting parts are guided, but the number of components and assembly steps increase
Solution Approach 1:
The patent combines multiple separate components (insulating stays and guides for fitting parts) into a single integrated insulating body. The insulating body includes fastening projections for securing profiled section elements and a hollow chamber with guiding contours for fitting parts, eliminating the need for separate components and reducing assembly steps.
Solution Approach 2:
The insulating body performs multiple functions simultaneously: it provides thermal insulation, secures profiled section elements against tilting through fastening projections, and guides fitting parts through the hollow chamber with guiding contours. This multi-functionality reduces the overall number of components needed in the construction element.
2Device complexity
If a monolithic insulating body with integrated hollow chamber is used, then the number of components is reduced, but the manufacturing complexity increases
Solution Approach 1:
The insulating body is designed with distinct functional segments: fastening projections for securing profiled section elements and a hollow chamber with guiding contours for fitting parts. This segmentation of functions within a monolithic structure allows for easier manufacturing compared to fully integrated complex shapes, as each segment can be formed using standard molding techniques.
3Productivity
If the insulating body integrates both fastening and guiding functions, then assembly is simplified, but the design complexity increases
Solution Approach 1:
The insulating body features localized functional areas: fastening projections at specific locations for securing profiled section elements and guiding contours within the hollow chamber for fitting parts. This local differentiation of qualities allows the insulating body to perform multiple functions without requiring complex overall design, as each local area is optimized for its specific function.

AI summary
An insulating body for multi-shell construction elements for spacing apart and thermally separating at least two profiled section elements relative to each other has a base member with a first side and a second side opposite the first side. Fastening projections are arranged on the first and second sides of the base member and secure the insulating body in receptacles of the profiled section elements. At least the first side has two of the fastening projections. The base member has a hollow chamber with an inner guiding contour for receiving and guiding fitting parts. A multi-shell construction element with at least two profiled section elements is provided with at least one such insulating body.
