Movable Cable Guide for Spindle Lighting Cable Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting devices with spindle units for power cables suffer from unreliable cable guidance, particularly when the wrap angle is small, leading to potential slippage and inoperability due to the power cable slipping off the guide roller.
Innovation Solution
A lighting device with a rotatable spindle unit and a movable cable guide unit, featuring a guide element that can change position relative to the spindle unit, ensuring reliable cable routing by preventing self-wrapping and maintaining a defined path for the supply cable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the power cable is guided over a guide roller with a small wrap angle, then the cable routing is simplified, but the cable can slip off the guide roller causing inoperability
Solution Approach 1:
The guide element is made movable relative to the spindle unit, allowing its position to be dynamically adjusted during cable winding and unwinding. This dynamic positioning ensures the cable maintains optimal contact with the guide element, preventing slippage while maintaining simple cable routing geometry.
Solution Approach 2:
A movable guide element acts as an intermediary between the cable and the fixed housing structure. This intermediary component can adapt its position to maintain proper cable guidance, mediating between the need for simple routing and reliable cable retention.
2Device complexity
If the guide element is fixed in position, then the device structure is simpler, but the cable may wrap around itself in small angles causing operational failure
Solution Approach 1:
The guide element's position is made dynamic rather than fixed, allowing it to move relative to the spindle unit during operation. This enables the system to maintain proper cable winding geometry without requiring complex fixed structural arrangements.
Solution Approach 2:
The cable guidance function is separated from the fixed housing structure and assigned to a distinct, movable guide element. This segmentation allows the guide element to independently adjust its position to prevent cable self-wrapping, while the overall device structure remains relatively simple.
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 enhances operational reliability by ensuring smooth winding and unwinding of the supply cable, reducing the risk of mechanical components tilting and improving cable management, allowing for adjustable lengths and positions of the light source.
Implementation Method 1
the guide element can be positioned in at least several different positions, either parallel to the axis of rotation or perpendicular to it. Preferably, the guide element is designed as a guide roller. Advantageously, the guide roller can move with the supply cable, in particular rotate, so that there is no relative movement between the supply cable and the guide element.
