Ceiling Robot Cable Routing via Hollow Arm Nesting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ceiling-mounted robots with wide movement envelopes face issues with relay cables becoming entangled with the articulated arm, leading to increased load on the cables due to direct connections to external devices.
Innovation Solution
The ceiling-mounted robot incorporates connector portions on the second arm portion, routing the relay cable through the arm to prevent entanglement, with one connector exposed on the bottom surface and another on the side surface, allowing for shorter connection paths and preventing cable sagging, and includes a hollow movable shaft for additional device connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a relay cable is directly connected to an external device outside the articulated arm, then the connection is simple and accessible, but the cable becomes entangled with the articulated arm during movement and experiences increased load
Solution Approach 1:
The relay cable is routed through the hollow interior of the articulated arm, nesting the cable within the arm structure. This prevents the cable from being exposed to external entanglement risks while maintaining connection functionality through connector portions that access the cable inside the arm.
Solution Approach 2:
The articulated arm acts as an intermediary structure that protects and guides the relay cable. The cable passes through the arm rather than connecting directly outside, using the arm's hollow space as a protective conduit that prevents entanglement while allowing cable access to external devices.
2Stability of the object's composition
If the connector portion is positioned on the side surface of the second arm portion, then the connection path is longer, but the cable can be connected above the bottom surface to prevent sagging
Solution Approach 1:
Different connector portions are positioned at different locations on the articulated arm (bottom surface vs. side surface) to serve different functional needs. The bottom surface connector optimizes for short connection paths, while the side surface connector optimizes for cable sagging prevention, allowing each location to have specialized quality characteristics.
