Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current gritting vehicle control systems fail to ensure reliable and time- and material-optimized de-icing and blunting of traffic routes, often resulting in delayed or unnecessary spreading operations.
Innovation Solution
A control device for gritting vehicles that establishes a wireless data connection with remote servers to receive weather and traffic route condition forecasts, combined with local surface parameter determination, allowing for precise and adaptive control of the gritting process based on real-time data, including surface temperature, humidity, and ice conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If gritting operations are performed based on conventional control systems, then spreading material is applied to traffic routes, but the operations are often delayed or unnecessarily performed on sections where sufficient adhesion already exists
Solution Approach 1:
The system performs preliminary actions by receiving and processing forecast data about upcoming weather conditions and traffic route states before actually needing to grit. The control device uses predicted information to proactively plan gritting operations, allowing the system to prepare and execute spreading tasks at the optimal moment rather than reacting delayedly to current conditions.
Solution Approach 2:
The control device continuously receives feedback from multiple sources including forecast data on weather and traffic route conditions, as well as real-time data from sensors measuring actual road surface parameters. This feedback loop enables the system to adjust gritting operations dynamically, ensuring spreading occurs only when and where actually needed based on both predicted and measured conditions.
2Reliability
If conventional control systems are used, then gritting operations are performed, but material usage is not optimized leading to unnecessary spreading
Solution Approach 1:
The system applies local quality by controlling the gritting device to spread material selectively at specific locations along the traffic route based on local conditions. The control device processes data to identify exact sections where gritting is needed versus sections where adhesion is already sufficient, enabling precise, location-specific spreading operations rather than uniform application across the entire route.
Solution Approach 2:
The control device monitors and responds to changes in road surface parameters such as temperature, humidity, and friction coefficient. By detecting parameter changes that indicate deteriorating road conditions, the system adjusts spreading material application accordingly, applying material only when parameters cross thresholds indicating actual need rather than using material preventively in all conditions.
3Measurement precision
If real-time control based on multiple data sources is implemented, then precise and adaptive gritting control is achieved, but device complexity increases
Solution Approach 1:
The control device achieves multi-functionality by integrating multiple data processing capabilities into a single system. It simultaneously receives and processes forecast data from external sources, reads data from various onboard sensors measuring different road parameters, and coordinates the gritting device operations. This universal control approach consolidates multiple functions into one device, managing complexity through integration rather than separate systems.
