Solution Overview

Problem

Existing vehicle communication systems face challenges in maintaining continuous automatic movement control when communication between the server and relay stations is restricted due to failures or congestion.

Innovation Solution

A movement control system that includes a moving object, a first control device for communicating with the object, and a second control device for relaying communication. When communication is unrestricted, the first control device performs first automatic movement control, and when communication is restricted, the second control device performs second automatic movement control, with the first control having fewer tasks assigned to the user.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the system relies on communication between the server and relay station for automatic movement control, then the control can be performed remotely via infrastructure, but the automatic movement control cannot be continued when communication is restricted due to failure or congestion

Engineering Contradiction:

Improvecontinuity of automatic movement controlVSAvoidcommunication infrastructure dependency

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The moving object is equipped with its own control capabilities to perform automatic movement control autonomously when external communication is restricted. The moving object serves itself by having onboard processing units that can execute control functions without relying on continuous external server communication, thus maintaining reliability while reducing infrastructure dependency.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system dynamically switches between two operational modes: when communication is available, the server performs first automatic movement control via the relay station; when communication is restricted, the moving object switches to performing second automatic movement control autonomously. This dynamic adaptation ensures continuity of control while adjusting the level of infrastructure dependency based on communication conditions.

Inventive Principle:

Principle #15Dynamics

2Ease of operation

If the first automatic movement control is performed via relay station, then remote server control is enabled, but the control cannot be maintained when communication between server and relay station is restricted

Engineering Contradiction:

Improveremote control capabilityVSAvoidcontrol continuity under communication restriction

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The moving object acts as an intermediary that can operate in two modes: receiving control instructions from the server via relay station when communication is available, and autonomously generating control decisions when communication is restricted. This intermediary capability ensures that remote control functionality is maintained when possible, while providing a fallback to autonomous operation for reliability.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The moving object is pre-equipped with the capability to perform automatic movement control autonomously, so that when communication with the server is restricted, it can immediately switch to self-controlled operation without interruption. This preliminary preparation of autonomous capability ensures control continuity while maintaining ease of remote operation when available.

Inventive Principle:

Principle #10Preliminary action

3Reliability

If the system switches to second automatic movement control when communication is restricted, then control continuity is maintained, but more tasks are assigned to the user compared to first automatic movement control

Engineering Contradiction:

Improvecontrol continuityVSAvoiduser task load

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system dynamically adjusts the level of automation and user involvement based on communication availability. When communication is available, first automatic movement control is performed with minimal user tasks. When communication is restricted, the system transitions to second automatic movement control where the moving object autonomously handles control decisions, maintaining reliability while managing user task load through adaptive automation levels.

AI summary

A movement control system includes: a moving object; a first control device capable of communicating with the moving object; and a second control device configured to relay the communication between the moving object and the first control device. When communication between the first control device and the second control device is not restricted, the first control device performs first automatic movement control on the moving object via the second control device, and when the communication between the first control device and the second control device is restricted, the second control device performs second automatic movement control on the moving object. The first automatic movement control has fewer tasks assigned to a user of the moving object than the second automatic movement control.
