Remote Activation of Paving Machine Components for Preheating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Paving machine components, such as heating assemblies and hydraulic systems, require significant time to reach operating temperatures, leading to delays and inefficiencies in paving operations due to the need for manual activation and temperature preheating, especially in varying weather conditions.
Innovation Solution
A system allowing remote activation of machine components via a network-connected controller, using information from an electronic device outside the worksite, including sensors to ensure the area is clear of obstacles, enabling the activation of components like heating systems and hydraulic pumps from a remote location using long-range communication protocols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If manual activation of heating assemblies and hydraulic components is used, then the machine components can be activated only after operator arrival, but the start-up time and operator downtime increase significantly
Solution Approach 1:
The system enables preliminary activation of heating assemblies and hydraulic components before the operator arrives at the worksite. The remote interface allows the operator to initiate component activation from a distant location, and the system automatically monitors and completes the warming process without requiring manual intervention upon arrival.
Solution Approach 2:
The system incorporates automatic monitoring and control features that allow the heating assemblies and hydraulic components to self-regulate their activation and warming processes. Sensors detect temperature and operational status, and the controller automatically adjusts component operation without requiring continuous manual intervention.
2Productivity
If remote activation via network-connected controller is implemented, then start-up time is reduced and operator downtime is minimized, but the system complexity and infrastructure requirements increase
Solution Approach 1:
The controller is designed to perform multiple functions: it serves as both the primary control unit for machine operations and the remote interface for preliminary activation. The same controller hardware and software handle both local operation and remote communication protocols, eliminating the need for separate dedicated remote activation systems.
Solution Approach 2:
The system uses existing network infrastructure (cellular, satellite, or wireless networks) as an intermediary for remote communication. Rather than building a dedicated communication system, the patent leverages widely available network protocols and infrastructure to enable remote activation and monitoring capabilities.
3Reliability
If component activation is delayed until operator arrival, then safety checks can be performed manually, but the overall paving operation efficiency decreases
Solution Approach 1:
The system incorporates sensors that continuously monitor the activation status and temperature of heating assemblies and hydraulic components. This feedback is transmitted to the controller, which automatically verifies that components have reached appropriate operational parameters before allowing full operation to commence, replacing manual safety checks with automated monitoring.
