Current ticketing systems in quarry operations are inefficient and prone to errors, as they fail to provide adequate mapping, inventory, and integration with work machines, leading to miscommunication between haul machine operators and wheel loader operators, resulting in incorrect material loading and resource wastage due to insufficient material availability and inaccurate inventory management.
Innovation Solution
A work order integration system that includes a management platform and control device capable of receiving and processing work order data, determining material availability, selecting optimal loading paths, and validating payload data to ensure accurate and efficient material loading operations, integrating with work machines to minimize operator errors and resource wastage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If work orders are electronically transmitted to wheel loader operators, then the indication of material type and amount improves, but miscommunication and errors between operators may still occur
Solution Approach 1:
The system implements feedback mechanisms where the work machine control device receives payload data from sensors and compares it against the work order data. The system provides feedback to operators about loading progress, material weight, and verification of correct material type, allowing for real-time correction of potential errors and ensuring communication accuracy between haul machine and wheel loader operators.
Solution Approach 2:
The patent replaces manual mechanical communication methods (hand signals, verbal communication) with electronic data transmission and automated control systems. The work machine control device electronically receives work order data and automatically processes payload information, eliminating the need for direct operator-to-operator communication and reducing human error.
2Device complexity
If haul machine operators manually search for stockpiles without integrated guidance, then system complexity remains low, but time and resources are wasted traveling between stockpiles
Solution Approach 1:
The management platform serves as an intermediary between the work order system and the work machines. It receives work order data, determines material availability at various stockpiles, identifies optimal stockpile locations, and transmits this information to the work machine control device. This intermediary system eliminates the need for operators to manually search for stockpiles while maintaining manageable system complexity.
Solution Approach 2:
The system performs preliminary actions by determining material availability and identifying optimal stockpile locations before the haul machine arrives. The management platform pre-processes work order data and prepares routing information, so that when the work machine reaches the worksite, it can immediately proceed to the correct stockpile without delay.
3Ease of operation
If work machines operate without integrated control and validation, then operational simplicity is maintained, but operator errors and resource wastage increase
Solution Approach 1:
The work machine control device performs self-service functions by automatically receiving work order data, processing payload information from sensors, validating loaded material against requirements, and determining when loading is complete. This automation reduces operator errors and ensures correct material loading without significantly complicating the operating procedure.
Solution Approach 2:
The system replaces manual operator judgment and verification with automated electronic control and sensor-based validation. Payload sensors automatically measure material weight and the control device validates this data against work order requirements, eliminating human error in determining correct loading while maintaining ease of operation through automated decision-making.
4Device complexity
If inventory management is not integrated with work orders, then system implementation is simpler, but material availability and queue wait times cannot be optimized
Solution Approach 1:
The patent merges the inventory management function with the work order processing system. The management platform simultaneously handles work order data, tracks material inventory at each stockpile, determines availability, and optimizes routing. This integration improves productivity by ensuring haul machines are directed to stockpiles with available material, while the complexity remains manageable through unified software control.
Data Source
AI summary
A work machine control device including a memory and a processor is disclosed. The processor may be configured to receive work order data associated with a haul machine. The work order data may identify the haul machine, a material requested for the haul machine, an amount of the material requested for the haul machine, and/or a work machine associated with the material. The processor may be configured to set an operating parameter of the work machine to perform an operation according to the work order data, and receive payload data associated with a payload of the work machine. The payload data may relate to a weight of the payload, a volume of the payload, and/or an operating state of the work machine. The processor may be configured to determine productivity data associated with the operation, and cause an action to be performed in connection with the productivity data.
