Slip Ring Signal Transmission via Conversion Units
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Military vehicles often face limitations in signal transmission between the vehicle hull and turret due to the limited number of conductor tracks in the slip ring, which is insufficient for the increasing demands of retrofitted devices, especially when additional weapons, optics, or sensors are added, leading to a shortage of available conductor tracks for signal transmission.
Innovation Solution
The method involves using conversion units to route signals via a smaller number of connecting conductors, allowing the signals to be transmitted over fewer conductor tracks, with the conversion units capable of converting and re-converting signals to ensure information integrity and compatibility, enabling efficient communication between the vehicle hull and turret even with limited available conductor tracks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the number of conductor tracks in the slip ring is increased to accommodate more signals, then the signal transmission capacity is improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
Multiple supply conductors carrying different signals are merged into a single connecting conductor through signal conversion. The conversion unit combines multiple signal streams into one, allowing multiple signals to share a single conductor track in the slip ring, thereby reducing the total number of conductor tracks needed.
Solution Approach 2:
A single connecting conductor in the slip ring serves multiple functions by carrying converted signals that represent multiple original supply conductors. The conductor track becomes a universal transmission medium that can carry composite signals from multiple sources through the conversion unit.
2Adaptability or versatility
If existing vehicles are retrofitted with additional devices, then the vehicle functionality is improved, but the number of required conductor tracks exceeds the available tracks
Solution Approach 1:
The signal transmission system becomes dynamic through the conversion unit, which can adaptively combine and route multiple signals through a fixed number of conductor tracks. This dynamic signal processing allows the system to accommodate varying numbers of devices and signals while using a constant, limited number of physical conductor tracks.
