Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

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

Engineering Contradiction:
Improveremote operation accuracyVSAvoidassignment process complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system performs preliminary assessment of terminal status (communication quality, controller health, environment) before assignment and pre-calculates suitability scores. This advance preparation ensures accurate matching without adding complexity to the actual assignment execution, as the evaluation work is done beforehand.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent replaces manual or simple automated terminal assessment with an automated evaluation system that uses sensors, communication modules, and processing units to objectively measure terminal status. This substitution enables precise, data-driven assignment decisions while maintaining computational efficiency through algorithmic scoring.

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

2Reliability

If terminal status evaluation is performed in real time, then remote operation accuracy is ensured, but system resource consumption increases

Engineering Contradiction:
Improveterminal suitability assessment accuracyVSAvoidsystem resource consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system performs terminal status evaluation periodically rather than continuously, assessing terminal suitability at defined intervals (e.g., before each assignment, or at scheduled checkpoints). This periodic approach maintains reliable assessment accuracy while significantly reducing computational overhead and energy consumption compared to continuous monitoring.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The system performs comprehensive terminal evaluation in advance before assignments are needed, pre-calculating suitability scores and storing results. This preliminary assessment eliminates the need for repeated real-time evaluations during operation, reducing resource consumption while ensuring reliability when assignments are made.

Inventive Principle:
Principle #10Preliminary action

3Measurement precision

If multiple terminal status parameters are evaluated, then assignment accuracy improves, but calculation complexity increases

Engineering Contradiction:
Improveterminal suitability measurement accuracyVSAvoidscore calculation complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The evaluation system divides terminal status assessment into separate modular components: communication status evaluation, controller health evaluation, environmental condition evaluation, and suitability score calculation. Each module independently assesses specific parameters and contributes to the final score, making the complex multi-parameter evaluation manageable and computationally efficient.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system transforms multiple diverse terminal status parameters (communication quality, controller temperature, environmental conditions) into a unified suitability score through standardized normalization and weighting. This parameter transformation enables accurate multi-dimensional assessment while simplifying the calculation process by converting complex parameters into comparable numerical values that can be aggregated efficiently.

Inventive Principle:
Principle #35Parameter changes

AI summary

A remote operating system (1) 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 (STA-T) indicating a status of a remote operator terminal (200) configured to be used by a remote operator (O) for the remote operation, and calculate a terminal score (SCR-T) indicating a suitability of the remote operator terminal (200) for the remote operation based on the terminal status information (STA-T). The terminal score (SCR-T) is used to select a first remote operator terminal (200-X) to be assigned to the remote operation of a target mobility device (100-X).
