Solution Overview
Problem
Existing height-adjustment solutions for beacon antennas on rail vehicles are complex, not user-friendly, and fail to adequately compensate for changes in antenna position due to wear on rail vehicle wheels.
Innovation Solution
A height-adjustable mount with a vehicle-side and antenna-side part, featuring a continuous height adjustment mechanism and independent locking mechanism operated by rotating screw elements, allowing precise and reliable adjustment of the antenna's vertical position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a height adjustment mechanism is provided for beacon antennas on rail vehicles, then the antenna height can be adjusted to compensate for wheel wear, but the adjustment mechanism becomes complex and not user-friendly
Solution Approach 1:
The mounting bracket is divided into distinct functional segments: a height adjustment mechanism with independent adjustment and locking functions, and a separate mounting structure. This segmentation allows each component to perform its specific function efficiently without unnecessary complexity in the overall system.
Solution Approach 2:
The locking function is extracted as an independent feature from the height adjustment mechanism. The locking element can be operated separately to secure the antenna at the desired height, decoupling the adjustment and locking operations to simplify the user interface and reduce operational complexity.
2Adaptability or versatility
If existing height adjustment solutions are used, then some height adjustment capability is provided, but they fail to adequately compensate for changes in antenna position due to wheel wear
Solution Approach 1:
The height adjustment mechanism provides localized adjustment capability at the antenna mounting point, allowing precise compensation for wheel wear without requiring adjustment elsewhere in the system. This targeted approach maintains reliable data transmission by keeping the antenna at the optimal height relative to the track bed.
Solution Approach 2:
The mounting bracket incorporates a dynamic height adjustment capability that allows the antenna height to be modified in response to changing conditions (wheel wear). This dynamic adjustment ensures continuous optimal performance despite gradual changes in the rail vehicle's geometry over time.
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
Enables easy, precise, and stable adjustment of the antenna's height above the track bed, compensating for changes in rail vehicle wheel wear, ensuring reliable data transmission and maintaining optimal alignment with data transmission units.
Implementation Method 1
a height adjustment means with which a position of the antenna-side part relative to the vehicle-side part can be continuously adjusted in a first direction, and a locking means independent of the height adjustment means, with which the position of the part on the antenna side that can be adjusted by means of the height adjustment means can be fixed relative to the part on the vehicle side, wherein the locking means can be operated by rotating a screw element about an axis running parallel to the first direction
