Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connection systems for building components in different temperature zones suffer from thermal bridging and limited anchoring capabilities, leading to inadequate insulation and structural instability under transverse forces.
Innovation Solution
A connection system featuring a pressure and shear force body made of pressure-resistant material, which absorbs pressure and transverse forces, combined with a tensile force-absorbing element like a threaded rod, minimizes deformation and thermal bridging by allowing secure attachment and thermal separation between components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If metal fasteners (screws, rivets) are used to connect building components in different temperature zones, then mechanical connection strength is improved, but thermal bridging occurs causing heat flow between temperature zones
Solution Approach 1:
The patent introduces a compression element made of thermally insulating material as an intermediary between metal fasteners and building components. This mediator prevents direct thermal contact while allowing mechanical force transmission, thus blocking thermal bridges without compromising connection strength.
Solution Approach 2:
The connection system uses composite construction combining metal fasteners for mechanical strength with thermally insulating compression elements for thermal isolation. This composite approach allows simultaneous achievement of both strong mechanical connection and thermal energy conservation.
2Reliability
If multiple dowels are staggered in rows or groups to achieve secure connection, then anchoring capability is improved, but installation complexity and labor intensity increase
Solution Approach 1:
The patent combines multiple anchoring functions into a single integrated connection element. The compression element with its specific geometric design provides distributed anchoring through one installation action, replacing the need for multiple staggered dowels and simplifying the installation process while maintaining reliable anchoring.
Solution Approach 2:
The connection element serves multiple functions simultaneously: it provides mechanical anchoring, thermal insulation, and load distribution in a single component. This multi-functionality eliminates the need for separate anchoring elements arranged in complex patterns.
3Device complexity
If a simple fastening element is used for connection, then device complexity is reduced, but thermal insulation performance deteriorates due to thermal bridging
Solution Approach 1:
The patent applies local quality by making only the necessary portions of the connection system thermally insulating. The compression element provides thermal insulation locally at the critical interface between temperature zones, while the rest of the system maintains simplicity. This targeted approach improves insulation without requiring complete system complexity.

Function Achieved in This Case
This solution ensures improved thermal insulation, reduced structural damage, and enhanced anchoring capabilities by effectively managing tensile, compressive, and shear forces, while preventing thermal bridging and deformation.
Implementation Method 1
a compression element in the form of a shear force body (12) arranged between the building and the second component... absorbs the compressive and shear forces acting upon it
Implementation Method 2
These two components are connected via a tensile force-absorbing element... This minimizes the deformation of the tensile element when the applied forces, especially shear forces, are present
Implementation Method 3
allowing heat to flow from the warmer to the colder components... a compression element in the form of a shear force body (12) arranged between the building and the second component

AI summary
A connection system is proposed for connecting a first building element, which is formed from a building and/or a substructure (16) for the building, with a second building element (18, 34), wherein the connection system has at least one element for tensile force absorption (10) and at least one compression and shear force body (12), so that a force couple is created in which the tensile force is absorbed by the element for tensile force absorption (10) and the compression and shear force are absorbed by the compression and shear force body (12).
