Angular Round Tube Profile Connection via Integrated Webs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for connecting round tube profiles at an angle, such as using T-shaped pipe connectors, require additional installation space and are not visually appealing, as they necessitate elements projecting outwardly, which is not suitable for all applications like attaching to a surface directly.
Innovation Solution
The connection of round tube profiles is achieved through beveled end faces forming an inverted V-shape, allowing the profiles to rest directly on a surface without additional elements, using complementary webs and receiving openings with a connecting screw for a space-saving and nearly invisible connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If T-shaped pipe connectors are used to connect round tube profiles at an angle, then the connection is achieved with sufficient structural integrity, but additional installation space is required and the connection is visually unattractive due to projecting elements
Solution Approach 1:
The connecting element is integrated directly into the round tube profile, merging the connection function with the tube itself. The web is formed as part of the tube structure, eliminating the need for separate T-shaped connectors and reducing installation space.
Solution Approach 2:
The connection is achieved by forming a web that extends radially outward from the tube profile, utilizing the radial dimension. This allows the connection to be made without adding length in the axial direction, thus saving installation space while maintaining structural integrity.
2Strength
If T-shaped pipe connectors are used to connect round tube profiles at an angle, then the connection is achieved with sufficient structural integrity, but the connection is visually unattractive due to external elements
Solution Approach 1:
The connecting element is integrated directly into the round tube profile, merging the connection function with the tube itself. The web is formed as part of the tube structure, eliminating the need for separate T-shaped connectors and reducing installation space.
3Reliability
If round tube profiles are connected using traditional connectors, then the connection is secure, but the profiles cannot rest directly on a surface due to surrounding connector elements
Solution Approach 1:
The connection is segmented into discrete components: the web with receiving openings and the connecting screw. This allows the connection to be made without requiring a surrounding connector structure, enabling the tube profiles to rest directly on surfaces.
Solution Approach 2:
The connection is achieved by forming a web that extends radially outward from the tube profile, utilizing the radial dimension. This allows the connection to be made without adding length in the axial direction, thus saving installation space while maintaining structural integrity.

AI summary
An arrangement of at least two round tube profiles connected at an angle to each other should be able to be connected to each other at an angle, preferably at right angles, in a space-saving manner. This is achieved by having several webs (6) projecting beyond the free end (4a) of the first round tube profile (4) at at least one end, and by having the second round tube profile (5) having at least one connection area (7) with several receiving openings (8) aligned with the webs (6), wherein a transverse web (9) with a first bore (10) arranged concentrically to the longitudinal axis of the first round tube profile (4) is arranged adjacent to the free end (4a) within the first round tube profile (4), wherein a second bore (11) aligned with the first bore (10) is recessed in the connection area (7) of the second round tube profile (5), wherein the first or the second bore (10,11) is provided with an internal thread for a connecting screw (12) that can be inserted through the second or the first bore (10, 11), wherein the webs (6) and the receiving openings (8) have complementary contact surfaces (6a, 8a) to each other and the contact surface (6a) of the respective web (6) is designed as a chamfered end face.
