Worksite Machine Availability Validation Using Mobile Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing worksite management systems lack a method to validate the availability of machines to perform specific tasks, leading to inefficiencies due to unclear machine status, obstructions, and unsuitable conditions, which can hinder task completion.
Innovation Solution
A worksite management system and method that includes a worksite controller and mobile device to receive task signals, identify machines, and prompt personnel to validate machine availability through images and prompts, facilitating validation of machine status, worksite conditions, and machine condition checks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If machines are coordinated according to worksite plan without validation mechanism, then task execution can proceed, but machine availability cannot be confirmed leading to task delays
Solution Approach 1:
The system performs preliminary validation of machine availability by sending prompts to personnel at the worksite before task execution begins. The worksite controller identifies required machines and obtains confirmation of their availability in advance, preventing task delays caused by unavailable equipment.
Solution Approach 2:
The system implements a feedback loop where the worksite controller sends availability validation prompts to personnel, receives their responses, and uses this feedback to determine whether machines are actually available before assigning tasks. This closed-loop approach ensures reliable confirmation of machine availability.
2Loss of information
If comprehensive machine validation is implemented, then accurate machine availability information is obtained, but system complexity increases
Solution Approach 1:
The worksite controller serves as an intermediary between the central system and personnel at the worksite. It receives task requirements, identifies needed machines, sends validation prompts to appropriate personnel, and relays responses back to the central system. This intermediary approach simplifies the overall system architecture by centralizing the validation logic.
Solution Approach 2:
The system leverages existing personnel at the worksite to provide validation information rather than requiring dedicated sensors or monitoring equipment on each machine. Personnel naturally observe machine availability and can confirm status through the mobile device interface, eliminating the need for complex automated detection systems.
3Measurement precision
If manual validation by personnel is required, then accurate real-time machine status is confirmed, but operational efficiency decreases
Solution Approach 1:
The mobile device serves multiple functions: it acts as a communication interface for receiving validation prompts, displays information about required machines, collects personnel responses, and transmits data back to the worksite controller. This multi-functional approach eliminates the need for dedicated validation equipment while maintaining accurate information collection.
Solution Approach 2:
Personnel at the worksite naturally observe and know the status of machines in their work environment. The system taps into this existing knowledge by simply asking them to confirm availability through the mobile device interface, rather than requiring them to perform separate validation tasks or use specialized equipment.

AI summary
A worksite management system may include a worksite controller including one or more worksite controller processors configured to receive a signal indicative of a task to be performed by a machine at a worksite, identify a machine for performing the task, and generate a signal indicative of the machine. The worksite management system may also include a mobile device including one or more mobile device processors configured to receive the signal indicative of the machine, display an image representative of the machine, and display a prompt for a person at the worksite to validate availability of the machine to perform the task.
