Solution Overview
Problem
Existing cable support systems require significant assembly effort and are prone to material failure under high loads due to the need for thick materials and complex geometries to achieve load-bearing capacity, leading to inefficiencies and material wastage.
Innovation Solution
A modular connection piece with separate fixing and fastening sections allows for optimized attachment to a supporting part, utilizing form-fitting locking elements to distribute forces effectively, reducing material requirements and enabling interchangeable components for various applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a double screw connection with thick materials and complex geometries is used to achieve load-bearing capacity, then the strength and reliability are improved, but the assembly effort and device complexity increase significantly
Solution Approach 1:
The connection piece is divided into distinct functional sections: a fixing section with locking elements for securing to the extension arm, and an attachment section for connecting to the supporting part. This segmentation allows each section to be optimized independently, reducing overall complexity while maintaining strength.
Solution Approach 2:
The connection piece acts as an intermediary component between the extension arm and the supporting part. It transfers forces between these components through its locking elements and attachment section, eliminating the need for complex direct connections while maintaining load-bearing capacity.
2Strength
If thick materials and complex geometries are used to ensure load-bearing capacity, then the strength is improved, but the material requirements and weight increase
Solution Approach 1:
The connection piece has non-uniform geometry with varying wall thicknesses optimized for specific functions: thicker regions at the locking elements for force transmission, and thinner regions where full strength is not required. This local quality optimization reduces material usage while maintaining load-bearing capacity.
Solution Approach 2:
The design changes material distribution parameters rather than uniformly increasing material thickness. By optimizing the geometry parameters of the locking elements and attachment section, the connection achieves high strength with minimal material, reducing the overall weight of the boom assembly.
3Ease of manufacture
If recesses are provided in the hanging support and boom for screw bolts, then the connection is achieved, but the recesses tend to tear out under higher loads
Solution Approach 1:
The locking elements are designed with engagement geometries that distribute loads across multiple contact points on the extension arm walls. This preliminary design consideration prevents stress concentration that would lead to tearing, while still allowing straightforward assembly through the recesses.
Solution Approach 2:
Instead of relying solely on single-point screw connections through recesses, the locking elements engage with the extension arm walls in multiple dimensions, distributing forces across a larger surface area. This prevents the recesses from tearing out under high loads while maintaining ease of assembly.

AI summary
The invention relates to an assembly of a cable support system 1 comprising a boom 2 for supporting a cable tray and a connecting piece 4 with a fixing section 7 for fixing to the boom 2. The connecting piece 4 engages in at least one recess in a wall of the boom 2 to form a force-transmitting positive locking in the longitudinal direction of the boom 2 with at least one locking element and with at least one fastening section adjoining the fixing section in the longitudinal direction of the boom 2 for connecting to a part 3 supporting the assembly.
