Solution Overview

Problem

Existing remote manipulation systems for working vehicles do not support remote operation, limiting their functionality.

Innovation Solution

A remote device and system that includes a remote manipulator, display, and controller to remotely control and monitor a working vehicle, displaying actual travel information and allowing for the superimposition of past travel routes on a captured image.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If the system is configured to automatically operate the working vehicle along selected past working routes, then automation capability is improved, but remote manipulation capability deteriorates (cannot support remote manipulation)

Engineering Contradiction:

Improveautomatic operation capabilityVSAvoidremote manipulation capability

Core Design Contradiction:

Extent of automationVSAdaptability or versatility

Solution Approach 1:

The remote device is designed to perform multiple functions: it can both automatically operate the working vehicle along selected routes and support remote manipulation operations. The display unit universally displays both captured images from the working vehicle and actual travel information, allowing the system to switch between automatic operation mode and remote manipulation mode without requiring separate systems.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Device complexity

If the display shows only captured images during remote manipulation, then display simplicity is improved, but operational guidance deteriorates (lack of actual travel information)

Engineering Contradiction:

Improvedisplay complexityVSAvoidremote operation guidance

Core Design Contradiction:

Device complexityVSEase of operation

Solution Approach 1:

The display unit merges two types of information that were previously displayed separately: captured images from the working vehicle and actual travel information from past operations. By superimposing or simultaneously displaying both types of information on the same display interface, the system provides comprehensive operational guidance while maintaining a unified, integrated display rather than requiring multiple separate displays.

Inventive Principle:

Principle #5Merging (Combining)

3Loss of information

If the system stores and displays multiple pieces of actual travel information, then information completeness is improved, but information selection complexity deteriorates

Engineering Contradiction:

Improvetravel information completenessVSAvoidinformation selection process

Core Design Contradiction:

Loss of informationVSDevice complexity

Solution Approach 1:

The system provides feedback to the operator by displaying multiple actual travel information pieces simultaneously or in sequence on the display unit. This allows the operator to review past travel routes and select the most appropriate one for current operations, creating an informative feedback loop that enhances decision-making without requiring complex external selection interfaces.

Inventive Principle:

Principle #23Feedback

AI summary

Remote manipulation is assisted (supported). A remote device (30) includes a remote manipulator (35) to remotely manipulate a working vehicle (1), a memory and/or a storage (32) to store an actual travel route which is a past record of travel of the working vehicle (1), a display (34) to display an image of an area in a direction of travel of the working vehicle (1) captured during remote manipulation, and a controller (31) configured or programmed to cause the display (34) to display the actual travel route stored in the memory and/or the storage (32) at least during remote manipulation of the working vehicle (1).
