Telescopic Column Internal Cable Guiding with Tensioning Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing telescopic columns face challenges in safely arranging and managing electric cables, leading to potential damage and unsightly, tangled cables that create trip hazards, while also limiting design flexibility.
Innovation Solution
A telescopic column design featuring a cable guiding means connected to a tensioning device that controls the cable's position based on the column's extension, ensuring the cable remains stretched and fixed at entry and exit points, using a pulley or wire mechanism to manage cable movement within the column, preventing interference with the drive mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cable is allowed to hang loosely outside the column, then the cable can reach the motor easily, but the cable creates trip hazards and unsightly appearance
Solution Approach 1:
The cable is extracted from the external environment and placed inside the telescopic column, removing it from the harmful external space where it could create trip hazards, while still maintaining its functional connection to the motor
2Ease of manufacture
If the cable is extended inside the telescopic column, then the appearance is clean and organized, but the cable may be damaged by the drive mechanism
Solution Approach 1:
The internal space of the telescopic column is segmented into distinct zones: the cable runs in a protected upper portion while the drive mechanism operates in a separate lower portion, preventing harmful interactions while maintaining clean appearance
Solution Approach 2:
A guiding means acts as an intermediary element that controls cable movement and positioning, ensuring the cable remains in a safe stretched state during column extension and retraction, preventing damage from the drive mechanism
3Stability of the object's composition
If the cable is fixed at both ends of the column, then the cable position is stable, but the cable cannot accommodate column extension and retraction
Solution Approach 1:
The cable arrangement transitions from a static fixed configuration to a dynamic system where the guiding means moves with the column extension, allowing the cable to maintain stability relative to the moving column structure while accommodating telescopic movement
4Adaptability or versatility
If a pulley arrangement is used to guide the cable, then the cable can move freely during extension, but the design becomes complicated and limited
Solution Approach 1:
The guiding means is merged with the column structure itself, integrating the cable guidance function into the existing telescopic mechanism rather than adding separate pulley systems, thereby maintaining design flexibility while enabling free cable movement
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution keeps cables out of sight, prevents tangling and damage, and maintains a clean appearance by ensuring the cable is always in a stretched state during extension and retraction, enhancing design flexibility and safety.
Implementation Method 1
a cable (30) extending inside the telescopic column (1). A cable guiding means (50) is connected to a tensioning device (52) arranged at the second end (5) of the telescopic column (1)
Implementation Method 2
using a pulley or wire mechanism to manage cable movement within the column

AI summary
The present application relates to a telescopic column (1) comprising a lower part (10) having a first end constituting a first end (4) of the telescopic column, an upper part (20) telescopically moveable relative to the lower part and having a first end constituting a second end (5) of the telescopic column opposite said first end of the telescopic column, a drive mechanism (2) configured to provide telescopic movement between the lower part and the upper part, an cable (30) extending inside the telescopic column, and a cable guiding means (50) coupled to a tensioning device (52) arranged at the second end of the telescopic column. The tensioning device is configured to control the position of the cable guiding means in the telescopic column based on the telescopic extension of the column, and the cable extends through the column via the cable guiding means. The present application further relates to an adjustable furniture (100) comprising at least one telescopic column.
