Telescopic Lifting Column Cable Guide for Multi-Cable Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of cables in electrically driven lifting columns, such as those for height-adjustable tables and hospital beds, leads to accidents due to incorrect connections, entanglement, and potential short-circuits, as existing solutions only address the guidance of a single cable and do not effectively manage multiple cables.
Innovation Solution
A telescopic cable guiding device is integrated into the lifting column, allowing for the secure guidance of multiple cables through telescopic rods or tubes, which can be placed inside or outside the column, providing protection and simplifying assembly, and can be retrofitted as needed with plug modules for easy connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple cables are connected to the lifting column for powering various equipment, then the functionality and versatility of the lifting column is improved, but the risk of cable-related accidents (entanglement, incorrect connections, short-circuits) increases
Solution Approach 1:
Multiple cables are bundled together and guided through a single telescopic cable guiding device, merging their paths and management into one integrated system. This reduces the complexity of managing multiple separate cables while maintaining all functional connections, thereby improving safety without sacrificing versatility
Solution Approach 2:
The telescopic cable guiding device acts as an intermediary structure that organizes and protects multiple cables. It provides a dedicated pathway that prevents cables from becoming entangled or incorrectly connected, while still allowing all necessary electrical connections to be made
2Device complexity
If cables are routed through the telescopic lifting column structure, then the cable management is simplified, but the cables may get squeezed and torn causing short-circuits
Solution Approach 1:
The telescopic cable guiding device serves as a protective intermediary between the cable and the lifting column structure. It provides a dedicated channel that guides the cable through the telescopic movement without allowing the column structure to squeeze or damage the cable, thus simplifying cable management while protecting cable integrity
Solution Approach 2:
The cable guiding device provides a flexible protective channel that can accommodate the telescopic movement of the lifting column. This flexible structure protects the cable from mechanical damage while allowing the necessary movement and simplifying cable routing
3Ease of operation
If existing cable guidance solutions are used, then single cable guidance is achieved, but multiple cables cannot be effectively managed
Solution Approach 1:
The telescopic cable guiding device is designed with universal functionality to accommodate multiple cables simultaneously. It provides a multi-channel structure that can guide several cables through the telescopic column, making it adaptable to various cable configurations and equipment setups while maintaining ease of operation
Solution Approach 2:
The cable guiding device is segmented into multiple independent channels or pathways, each capable of accommodating a separate cable. This segmentation allows effective management of multiple cables while maintaining the simplicity and ease of operation characteristic of single-cable guidance systems

AI summary
A telescopic lifting column (1) preferably for furniture, such as height adjustable tables and beds, and comprising at least two mutually telescopic members (2,3,4) and an electric drive unit (5, 10;41,42) for adjusting the telescopic members. The lifting column comprises a telescopic cable guiding device (22;45, 58, 80, 103) for guiding at least one electric cable (29), where the telescopic cable guiding device extends between or in all essentials between the lower and upper end of the lifting column and is connected thereto so that the telescopic cable guiding device collaborates in the telescopic adjustment of the lifting column. Thus the cables may be guided in a protected manner.
