Solution Overview

Problem

The challenge lies in remotely operating machines such as excavators and graders safely and efficiently, as skilled operators with the necessary training for remote operation are scarce, leading to delays and increased costs due to the need for additional training and the hazards associated with on-site operation.

Innovation Solution

A system utilizing a portable computing device with a controller that can be removably mounted on both the machine and a remote control console, equipped with sensors and a visual image sensor, allowing for real-time monitoring and control of machine operations, and enabling operators to manage machine functions from a distance with a configuration that mirrors the on-site instrument array.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If machines are operated remotely, then operator safety is improved, but the complexity of the control system increases

Engineering Contradiction:
Improveoperator safetyVSAvoidcontrol system complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The remote control console is configured to substantially duplicate the on-board console's display devices and input devices. This copying approach allows operators to work from a safe remote location while maintaining familiar controls, thus improving safety without significantly increasing operational complexity.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The controller system serves multiple functions: it operates the machine when the operator is on-board, and it enables remote operation when the operator is at the remote console. This multi-functionality resolves the contradiction by using the same hardware infrastructure for both local and remote operations.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Ease of operation

If additional training is provided to develop operators qualified for remote operation, then operator skill level is improved, but operation costs and project delays increase

Engineering Contradiction:
Improveoperator skill levelVSAvoidtraining time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

By duplicating the on-board console interface at the remote location, operators can transition to remote operation without extensive retraining. The familiar control layout and display configurations reduce the learning curve, thus improving ease of operation while minimizing training time requirements.

Inventive Principle:
Principle #26Copying

3Adaptability or versatility

If the remote control console uses a different interface configuration, then adaptability to remote operation is improved, but operator training requirements increase

Engineering Contradiction:
Improveremote operation capabilityVSAvoidoperator training requirements
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The remote control console substantially duplicates the on-board console's display devices and input devices in the same arrangement. This copying strategy provides adaptability for remote operation while maintaining ease of operation by using familiar interfaces, thus resolving the contradiction between adaptability and training requirements.

Inventive Principle:
Principle #26Copying

AI summary

A controller implemented method of remotely operating a machine includes determining, for each of a plurality of operating conditions of the machine, a predetermined configuration of a machine instrument array and removably mounting a portable computing device on a remote control console. The method further includes defining a configuration of a console instrument array of the remote control console in which, for each of the plurality of operating conditions, the configuration of the console instrument array is generally identically to the predetermined configuration of the machine instrument array. A system is also disclosed.
