Support Arm Connector for Rigid Quasi-Closed Profile
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing support arm systems face challenges in achieving high profile rigidity while maintaining easy cable installation and assembly efficiency, especially under high loads.
Innovation Solution
A support arm system with a connector that connects the projections delimiting the insertion opening, providing a quasi-closed hollow profile, and featuring clampable fasteners for secure attachment, along with molded-on limiting elements for enhanced rigidity and media routing capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the support profile is closed on all sides to achieve high rigidity, then profile rigidity is improved, but cable installation becomes more difficult
Solution Approach 1:
The connector is divided into two separable fastening parts that can be opened to create an insertion opening for cables, then closed to form a rigid quasi-closed hollow profile. This segmentation allows the structure to be both installable and rigid.
Solution Approach 2:
The connector transitions from an open state during installation to a closed state for operation. The two fastening parts can be moved relative to each other to open and close the insertion opening, providing dynamic adaptability between installation and operational phases.
2Adaptability or versatility
If additional attachments are added to the support profile, then functionality is improved, but device complexity increases
Solution Approach 1:
The connector serves multiple functions: it closes the support profile to create rigidity, provides attachment points for additional components, and maintains the quasi-closed hollow profile structure. This multi-functionality reduces the need for separate components.
Solution Approach 2:
The connector integrates the closing function and the attachment function into a single component. The fastening parts that close the profile also serve as mounting points for additional attachments, merging structural and functional elements.

AI summary
The shaft has a supporting profile (10) partially surrounding a retaining area (A) that is in spatial connection with an environment over an insertion opening. The opening is limited by attachments (17) of the profile, where the attachments lie opposite to each other. The attachments are connected with one another by a connector (30) that comprises fastening parts (31, 32) deformed opposite to each other. The attachments and the fastening parts are in effective connection with one another over clamping sections. The attachments are engaged to projections (31.1, 32.1) of the fastening parts.
