Closed Slide Track Attenuation for Signal Reflection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical transmission systems, such as sliprings and slide tracks, face challenges in minimizing signal interference and achieving high bandwidths, especially in large arrangements, due to reflections and increased wear from discontinuous conductor paths, which lead to data losses at high data rates.
Innovation Solution
The implementation of closed slide tracks with built-in attenuating resistors, either in series or parallel, to intentionally reduce signal amplitude by at least 6 dB, thereby minimizing reflections and eliminating the need for additional termination resistors, and uniformly distributing attenuating components to ensure consistent attenuation along the track.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a terminal resistor is disposed at a position diametrically opposite to the feed-in position to improve signal transmission, then signal reflections are reduced, but two movable taps are needed which increases production costs and wear
Solution Approach 1:
The invention extracts the terminal resistor function from a separate component and integrates it directly into the slide track structure itself. The slide track is designed with high electrical resistance material or high impedance characteristics along its entire length, eliminating the need for separate terminal resistors and additional movable taps while maintaining signal transmission quality.
Solution Approach 2:
The slide track serves multiple functions simultaneously: it provides the electrical connection path for signal transmission and inherently provides the termination resistance function through its high impedance characteristics. This multi-functionality eliminates the need for separate terminal resistor components and additional movable taps.
2Reliability
If a discontinuous conductor path is used to achieve reflection-free termination, then signal reflections are minimized, but wear on contact brushes increases and manufacturing becomes more difficult
Solution Approach 1:
The invention changes the electrical parameter (impedance/resistance) of the continuous slide track material itself to provide termination function. By designing the slide track with high electrical resistance or high impedance characteristics along its entire length, the continuous structure inherently provides reflection-free termination without requiring physical discontinuities or breaks in the conductor path.
3Reliability
If additional termination resistors and movable taps are added to improve signal transmission, then signal reflections are reduced, but production costs and device complexity increase
Solution Approach 1:
The invention merges the terminal resistor function with the slide track structure itself. The slide track is designed with inherent high impedance characteristics that provide both the signal transmission path and the termination function in a single integrated component, eliminating the need for separate terminal resistors and additional movable taps.
Solution Approach 2:
The slide track serves multiple functions simultaneously: it provides the electrical connection path for signal transmission and inherently provides the termination resistance function through its high impedance characteristics. This multi-functionality eliminates the need for separate terminal resistor components and additional movable taps.
4Ease of manufacture
If a continuous slide track is used to simplify manufacturing, then fabrication is easier, but signal reflections occur at termination points
Solution Approach 1:
The invention changes the electrical parameter (impedance/resistance) of the continuous slide track material itself to provide termination function. By designing the slide track with high electrical resistance or high impedance characteristics along its entire length, the continuous structure inherently provides reflection-free termination without requiring physical discontinuities or breaks in the conductor path.

AI summary
A device such as a slide track or a slipring for transmitting electrical energy or signals between at least two units that are rotatable relative to each other along a path of rotation comprises at least one slide track formed as a closed circuit of electrically conducting material disposed along the path of rotation, and at least one tap movable along the slide track for coupling electrical signals into the slide track from one of the units, or coupling electrical signals out of the slide track to one of the units. In order to reduce a superposition of signals that have traveled along different directions along the closed circuit, the at least one slide track is configured to have electric losses resulting in an amplitude of an electrical signal coupled into the slide track being reduced by at least 6 dB, preferably 10 dB, during a passage of the signal along one entire length of the slide track.
