Modular Track Support Design for Efficient Maintenance
Here’s PatSnap Eureka !
Summary
Problems
Current electric power supply systems for land vehicles, such as trams, face challenges in maintenance due to complex replacement processes, insufficient mechanical strength, and logistical issues with bending and installing curved supports.
Innovation solutions
A track support system with a V-shaped lower surface for easy detachment and increased robustness, made from elastomeric material, allowing for elastic deformation and improved anchoring with through-holes and recesses for secure attachment, along with a method for implanting the system that simplifies the installation process.
TRIZ Analysis
Specific contradictions:
General conflict description:
Principle concept:
If segments are attached by adhesive bonding and screwing to the support, then the attachment is secure, but the support degrades during detachment and replacement becomes extremely complex
Why choose this principle:
The support is divided into modular sections that can be independently replaced. The track support system consists of multiple supports that can be detached and replaced as individual units, simplifying maintenance operations while maintaining secure attachment during service.
Principle concept:
If segments are attached by adhesive bonding and screwing to the support, then the attachment is secure, but the support degrades during detachment and replacement becomes extremely complex
Why choose this principle:
The attachment mechanism is extracted from the support structure itself and implemented as separate, removable fastening elements. This allows segments to be securely attached during operation but easily removed for maintenance without degrading the support.

Abstract
This support ( 36 ), as a profile in an electrically insulating material, comprises a substantially planar upper surface ( 50 ), provided with a longitudinal flute ( 60 ) intended for receiving a track segment, and a longitudinal groove ( 70 ) intended for receiving a low voltage electric power supply cable; and a lower surface ( 52 ) intended to bear upon a base for maintaining the support in the roadway. It is characterized in that the lower surface ( 52 ) is curved, preferably V-shaped, so that the support is concave so as to be at least transversely maintained in a recess with a mating shape, made in the base.
