Solution Overview

Problem

Existing remote operation systems for mobility devices do not consider the status of the remote operator terminal, leading to decreased accuracy in remote operations.

Innovation Solution

A remote operating system that acquires terminal status information and calculates a terminal score to assess the suitability of the remote operator terminal for the remote operation, ensuring accurate assignment of operators and terminals.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If remote operator terminals are assigned without considering their status, then the assignment process is simple and fast, but the accuracy of remote operation decreases

Engineering Contradiction:
Improveaccuracy of remote operationVSAvoidcomplexity of terminal status assessment
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies parameter changes by introducing a terminal score system that quantifies terminal status through multiple parameters (communication status, controller abnormality level, etc.). This transforms the abstract concept of terminal suitability into measurable parameters, enabling systematic assessment without excessive complexity. The terminal score serves as a composite parameter that integrates multiple status indicators into a single evaluative metric.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent replaces manual or simple assignment mechanisms with an automated scoring system. Instead of relying on operator judgment or basic assignment protocols, the system uses automated calculation of terminal scores based on real-time status data. This substitution of mechanical/simple processes with automated information processing resolves the contradiction by making the assessment systematic yet computationally efficient.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Measurement precision

If terminal status is assessed in real time, then the suitability assessment is accurate, but the processing time and computational load increase

Engineering Contradiction:
Improveprecision of terminal suitability assessmentVSAvoidtime for score calculation
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system performs preliminary actions by continuously monitoring and pre-assessing terminal status parameters even before assignment decisions are made. Communication status and controller health are tracked in advance, so when assignment time arrives, the terminal score is already calculated or can be quickly updated. This preliminary assessment reduces the time penalty of real-time evaluation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements continuous monitoring of terminal status parameters, maintaining an ongoing assessment rather than periodic checks. This continuity ensures that the terminal score always reflects current conditions without requiring intensive processing at assignment moments. The useful action of status assessment continues seamlessly in the background, minimizing time loss while maintaining precision.

Inventive Principle:
Principle #20Continuity of useful action

AI summary

A remote operating system for a remote operation of a mobility device includes one or more processors. The one or more processors are configured to acquire terminal status information indicating a status of a remote operator terminal configured to be used by a remote operator for the remote operation, and calculate a terminal score indicating a suitability of the remote operator terminal for the remote operation based on the terminal status information. The terminal score is used to select a first remote operator terminal to be assigned to the remote operation of a target mobility device.
