Solution Overview

Problem

Remote operators of work machines face challenges in efficiently confirming the surroundings of the machine due to their distance, making it difficult to perform tasks effectively.

Innovation Solution

A work assistance server generates and displays a surroundings image of the work machine on a remote operation apparatus's display device, ensuring the operator confirms the image for a predetermined time before allowing the machine to operate, using a combination of image pickup devices and processing elements to facilitate remote operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If multiple fixed point cameras are installed at the work site to monitor the entire site, then the operator can overlook the site, but the operator cannot efficiently confirm the specific surroundings of the work machine due to distance

Engineering Contradiction:
Improvesurroundings informationVSAvoidconfirmation efficiency
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The patent uses image pickup devices mounted on the work machine to capture real-time video images of the surroundings, creating a visual copy of the environment that is transmitted to the remote operation apparatus. This allows the operator to see the surroundings as if present at the site, solving both the information loss and confirmation efficiency problems

Inventive Principle:
Principle #26Copying

2Reliability

If the operator remotely operates the work machine from a distance, then safety is improved, but the operator cannot efficiently perceive the situation around the work machine

Engineering Contradiction:
Improveoperational safetyVSAvoidsurroundings perception
Core Design Contradiction:
ReliabilityVSLoss of information

Solution Approach 1:

The patent introduces video images captured by image pickup devices as an intermediary between the operator and the work machine surroundings. These images serve as a mediator that transmits visual information about the environment to the remote operator, maintaining safety distance while preserving situational awareness

Inventive Principle:
Principle #24Intermediary (Mediator)

3Loss of information

If cameras are attached to the work machine to capture images, then the operator can recognize positional relationships, but the operator still faces difficulty in efficiently confirming the video image due to remote operation distance

Engineering Contradiction:
Improvepositional relationship informationVSAvoidwork confirmation efficiency
Core Design Contradiction:
Loss of informationVSProductivity

Solution Approach 1:

The patent employs image pickup devices that serve multiple functions: capturing wide-angle views of the surroundings, providing real-time video feeds, and enabling the operator to recognize positional relationships with objects. This multi-functional approach efficiently addresses both information loss and productivity concerns in remote operation

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