Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sensor systems sunk under the roadway surface, such as those used in slot car tracks, face difficulties in integration, maintenance, and vibration-induced accuracy issues, making precise positioning and quick assembly challenging.
Innovation Solution
The sensor system is pre-assembled on a guide element that can be inserted sideways under the roadway, allowing for precise positioning and easy maintenance, with cables pre-assembled and sensor units spaced according to lane divisions, and featuring sliding guide means for accurate alignment and protection from vibrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sensor units are sunk under the roadway surface, then vehicle detection can be achieved, but integration and maintenance become difficult and positioning precision is compromised
Solution Approach 1:
The sensor system is divided into modular sensor units that can be independently mounted on guide elements. Each sensor unit is a self-contained module that can be easily installed, removed, and maintained without affecting other sensors, thus improving ease of manufacture while maintaining detection precision through proper positioning.
Solution Approach 2:
Guide elements are introduced as intermediary components between the sensor units and the roadway. These guide elements facilitate precise positioning of sensors under the roadway while enabling easy installation and maintenance, as they can be quickly inserted and removed without complex integration procedures.
2Measurement precision
If sensor units are sunk under the roadway surface, then vehicle detection is enabled, but removal and repositioning are time-consuming
Solution Approach 1:
Guide elements are pre-prepared with mounting features and positioning mechanisms before installation. This preliminary preparation allows sensor units to be quickly attached and precisely positioned without time-consuming adjustments during maintenance, reducing overall maintenance time while ensuring accurate sensor placement.
3Ease of manufacture
If sensor units are placed directly on the roadway, then installation is simplified, but vibrations from racing vehicles affect measurement accuracy and sensor lifespan
Solution Approach 1:
Guide elements serve as intermediary structures that elevate sensor units above direct contact with the roadway surface. This intermediary positioning maintains installation simplicity through easy attachment to the guide elements while protecting sensors from vibrations generated by racing vehicles, thus improving reliability.
4Adaptability or versatility
If multiple sensor units are installed for multi-lane tracking, then comprehensive vehicle monitoring is achieved, but integration complexity and maintenance difficulty increase
Solution Approach 1:
The multi-lane monitoring system is segmented into independent sensor units, each responsible for a specific lane. Each unit is mounted on its own guide element, allowing individual installation, configuration, and maintenance without affecting other lanes, thus reducing overall system complexity while maintaining comprehensive monitoring capability.

AI summary
The present invention relates to a device for detecting, monitoring and/or controlling racing vehicles on a preferably multi-lane racetrack, having at least one sensor unit which is arranged countersunk under the surface of a carriageway. According to the invention, the at least one sensor unit is mounted on a guide element which can be inserted into a receptacle space under the carriageway in the transverse direction with respect to the carriageway, from the lateral edge of the carriageway. In this context, cables, lines or the like can be pre-assembled in a complete state with the at least one sensor unit and can be inserted under the carriageway from the side together with the guide element, with the result that there is no need for any separate laying of cables or even for a cable connection once the sensor is in position.
