Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing T-connections for post-transom constructions in facades, skylight roofs, and winter gardens lack sufficient load-bearing capacity and stability, particularly in supporting heavy glass or filling weights, and fail to effectively absorb torsional moments and deflections.
Innovation Solution
A T-connection system featuring pin-shaped connecting elements fastened to a post profile with a connector, a connection profile that can be positively plugged into the transom profile, and a holding profile with threaded holes, providing a stable and secure attachment that absorbs torsional moments and reduces deflection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional T-connections are used for post-transom constructions, then the structure can be assembled, but the load-bearing capacity is insufficient to support heavy glass or filling weights
Solution Approach 1:
The connecting device is divided into multiple functional components: a connecting profile with insertion areas, multiple pin-shaped connecting elements distributed at predetermined positions, and a retaining profile. This segmentation allows each component to contribute specifically to load distribution and structural stability, enabling the connection to support heavy glass or filling weights effectively.
Solution Approach 2:
The connecting device combines different material properties and structural forms - the connecting profile provides a rigid framework, while the pin-shaped connecting elements (which can be threaded or smooth) offer flexible connection options. This composite approach creates a connection system with superior load-bearing capacity compared to conventional single-structure connections.
2Stability of the object's composition
If conventional T-connections are used, then assembly is possible, but the connection fails to effectively absorb torsional moments and deflections
Solution Approach 1:
The connecting profile incorporates wave-shaped areas with lateral receiving areas in addition to the primary insertion areas. This dimensional expansion from simple linear insertion to multi-directional receiving areas enables the connection to absorb torsional moments and deflections occurring in multiple planes, significantly improving stability without excessive complexity.
Solution Approach 2:
The pin-shaped connecting elements are positioned at predetermined arrangements and orientations within the connecting profile before final assembly. This preliminary positioning ensures that the connection is pre-configured to absorb torsional moments and deflections, providing enhanced stability from the moment of assembly rather than requiring complex adjustment mechanisms.
3Reliability
If multiple connecting elements are used to improve load-bearing capacity, then the connection becomes more stable, but the device complexity increases
Solution Approach 1:
The connecting profile integrates multiple insertion areas and lateral receiving areas into a single unified component that can accommodate multiple pin-shaped connecting elements. The retaining profile similarly combines multiple fastening functions. This merging approach achieves high connection stability through multiple connection points while avoiding the complexity of separate discrete components for each function.
Solution Approach 2:
The connecting profile serves multiple functions simultaneously: it provides structural support, accommodates multiple pin-shaped connecting elements at predetermined positions, absorbs torsional moments through wave-shaped areas, and enables precise positioning. This multi-functionality achieves high reliability without proportionally increasing device complexity, as one component performs all critical connection tasks.

AI summary
The invention relates to a T-connection for post-and-beam constructions of facades, skylights, and conservatories, which includes a connecting device for the positive-locking connection of a beam profile (2) to a post profile (1). The connecting device comprises several pin-shaped connecting elements (11) that can be attached to a side wall (5) of the post profile (1) in a predetermined pattern and a connecting profile (12) that can be positively fitted onto the pin-shaped connecting elements (11) and inserted into the beam profile (2). The connecting profile has several insertion areas (25, 26) adapted to the outer contour of the pin-shaped connecting elements (11) and their arrangement for insertion and positive-locking reception of the pin-shaped connecting elements (11).
