Current Collector Antenna Decoupling for Stable Waveguide Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing conductor line systems experience impaired data transmission due to wear-induced changes in the depth of penetration of antennas into slotted waveguides, leading to inconsistent electrical contact and attenuation issues, particularly in systems supplying multiple electrical loads.
Innovation Solution
The antenna is mounted to move relative to the sliding contact, with spacer elements and a compensating element to maintain consistent depth of penetration, allowing the sliding contact to maintain contact while the antenna remains stationary, ensuring uninterrupted data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the sliding contact is pressed against the conductor profile to ensure reliable electrical contact, then electrical contact reliability is improved, but the antenna penetrates deeper into the slotted waveguide due to sliding contact wear, worsening data transmission quality
Solution Approach 1:
The current collector is segmented into functionally independent components: the sliding contact portion and the antenna portion are separated and mounted on independent carriers (sliding contact carrier and antenna holder respectively). This allows each component to perform its function independently without interfering with the other, resolving the contradiction between maintaining electrical contact and preserving data transmission quality.
Solution Approach 2:
The antenna is mounted on an antenna holder that can move independently in the feed direction relative to the sliding contact. This dynamic mounting allows the antenna to maintain a constant depth of penetration into the slotted waveguide even as the sliding contact wears and moves closer to the conductor profile, thereby maintaining data transmission quality while allowing the sliding contact to maintain reliable electrical contact.
2Loss of information
If the antenna is inserted into the slotted waveguide for data transmission, then data transmission capability is improved, but wear of the sliding contact causes the antenna to move deeper into the waveguide, worsening transmission characteristics
Solution Approach 1:
The antenna holder is designed to move independently in the feed direction, decoupling the antenna position from the sliding contact position. This dynamic independence ensures that the antenna maintains a consistent depth of penetration into the slotted waveguide throughout the operational life of the sliding contact, preserving transmission characteristics consistency while enabling data transmission capability.
Solution Approach 2:
The antenna holder acts as an intermediary between the sliding contact carrier and the antenna. It absorbs the relative movement caused by sliding contact wear through its independent movement capability, thereby mediating between the mechanical wear process and the antenna position to maintain consistent transmission characteristics.
3Productivity
If multiple electrical loads are supplied along the conductor line, then power distribution capability is improved, but changing load conditions cause varying antenna penetration depths, worsening data transmission stability
Solution Approach 1:
The independent movement capability of the antenna holder in the feed direction allows it to compensate for variations in antenna penetration depth caused by changing load conditions and multiple electrical loads along the conductor line. This dynamic adjustment maintains data transmission stability while enabling versatile power distribution capability.
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
This configuration maintains consistent data transmission properties over time by preventing the antenna from penetrating deeper into the waveguide, reducing wear-related issues and maintaining reliable electrical contact.
Implementation Method 1
The sliding contact is continuously pressed by spring force in the direction of the grounding conductor profile
Implementation Method 2
at least one a spacer element, in particular a spacer slide or a spacer roller for sliding or rolling on the conductor profile, can be disposed on the antenna holder

AI summary
A current collector has a sliding contact for making electrical contact with a conductor profile of a conductor line, and an antenna for insertion into a longitudinal slot, which runs in a longitudinal direction of the conductor line. The sliding contact and the antenna can be moved jointly towards the conductor profile in a feed direction by a feed device of the current collector. The antenna is movably mounted on the current collector. Also provided are a conductor line and a conductor line system.
