Lateral Contact Wire Support Geometry for Safe Side Deflection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing overhead line systems face issues with lateral contact wire fixation, particularly in non-rail-bound vehicles where significant lateral movements can cause the contact wire to leave the intended contact area, leading to dangerous interactions with the side holder arrangement and contact wire clamp.
Innovation Solution
The side holder arrangement features an adjustable design with overlapping elements and a contact wire clamp that widens transversely, creating a clearance above and to the side of the contact wire, allowing safe lateral movement and attachment of the contact wire, with an obtuse angle between 95° and 110° and a maximum horizontal expansion of >65°, ensuring the contact wire can be dragged harmlessly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the contact wire is laterally fixed by a rigid side holder arrangement, then the contact wire is stable in position, but the contact wire cannot accommodate lateral movements of non-rail-bound vehicles, leading to dangerous contact with the side holder
Solution Approach 1:
The side holder arrangement is designed with movable connection at one end to the support element, allowing dynamic adjustment and movement accommodation. This enables the contact wire to move laterally within safety limits without rigid constraint, preventing dangerous contact while maintaining operational stability.
Solution Approach 2:
The side holder arrangement allows the contact wire to change its lateral position parameter within defined limits. By permitting controlled parameter variation rather than fixed positioning, the system adapts to lateral movements of non-rail-bound vehicles while maintaining safe operation.
2Adaptability or versatility
If the contact wire is allowed to move laterally freely, then the contact wire can accommodate vehicle movements, but the contact wire loses positional stability and may contact the side holder dangerously
Solution Approach 1:
The movable connection provides dynamic stabilization, allowing the contact wire to move laterally within safe limits while automatically returning to or maintaining its proper position. This dynamic mechanism ensures both movement accommodation and positional stability.
Solution Approach 2:
The side holder arrangement is positioned and configured to provide beforehand cushioning against excessive lateral movement. The movable connection allows controlled movement while preventing dangerous contact, cushioning against potential hazards before they occur.
3Device complexity
If the side holder arrangement is fixed in design, then the structure is simple, but post-installation adjustments are complex or impossible
Solution Approach 1:
The side holder arrangement is segmented into modular components that can be independently adjusted. This segmentation maintains structural simplicity while enabling easy post-installation adjustments through reconfiguration of individual segments.
Solution Approach 2:
The movable connection component provides inherent adjustability without complicating the overall structure. This dynamic element allows post-installation positioning adjustments while maintaining the simplicity of the fixed portions of the arrangement.

AI summary
The invention relates to a lateral support system (13) for laterally fixing a contact wire (2) of an overhead line system (1), comprising at least one contact wire clamp (14), which is designed to be secured to the contact wire (2), and at least one lateral support (15), which is connected to the contact wire clamp (14) at one end (19) and the other end (20) of which is designed to be movably connected to a support element (12) of the overhead line system (1). The aim of the invention is to allow a lateral contact of the contact wire. According to the invention, this is achieved in that the lateral support (15) has at least two lateral support assemblies (27, 28) which are arranged at an obtuse angle (ß) to each other, wherein a lateral support section is connected to the contact wire clamp. The invention additionally relates to an overhead line system.
