Solution Overview

Problem

Existing technologies for unmanned air vehicles (drones) and similar moving bodies do not effectively disable remote control and autopilot operations when the operator cannot visually see the vehicle, violating regulatory requirements for safe operation.

Innovation Solution

A moving body equipped with a light emitter, receiver, detector, and controller that records its position when the operator or supervisor can see the light and returns to that position if they cannot, thereby disabling remote control and autopilot until visual confirmation is re-established.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the moving body operates without visual confirmation, then operation flexibility and autonomy are improved, but safety and regulatory compliance deteriorate

Engineering Contradiction:
Improveoperation flexibilityVSAvoidsafety compliance
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system implements feedback by having the light emitter send light to the operator, who then provides response information back to the moving body. This closed-loop feedback mechanism ensures the operator can see the moving body and confirms visual contact, resolving the contradiction by enabling safe operation only when visual confirmation is established.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The moving body autonomously monitors its own operational status by receiving response information and automatically determining whether visual confirmation exists. When visual confirmation is lost, the system self-corrects by disabling operations or returning to the last confirmed position, eliminating the need for external intervention and ensuring continuous safety compliance.

Inventive Principle:
Principle #25Self-service

2Reliability

If the moving body returns to last position when visual confirmation is lost, then safety is improved, but operational continuity and productivity deteriorate

Engineering Contradiction:
ImprovesafetyVSAvoidoperational continuity
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The system applies partial action by disabling only the necessary operations (remote control and autopilot) when visual confirmation is lost, rather than completely shutting down the system. This allows non-critical functions to continue while maintaining safety, resolving the contradiction between safety and operational continuity.

Inventive Principle:
Principle #16Partial or excessive action

Solution Approach 2:

The system records the last position where visual confirmation was established, preparing for potential return in advance. This preliminary recording enables quick and efficient return to a safe position when visual confirmation is lost, minimizing operational disruption while ensuring safety.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If the system continuously monitors visual confirmation, then regulatory compliance is improved, but system complexity and energy consumption deteriorate

Engineering Contradiction:
Improveregulatory complianceVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system uses periodic action by having the light emitter send light at regular intervals rather than continuously. The operator provides response information periodically, confirming visual contact at these intervals. This periodic monitoring maintains regulatory compliance while reducing system complexity and energy consumption compared to continuous monitoring.

Inventive Principle:
Principle #19Periodic action

AI summary

A moving body includes a drive that causes the moving body to move, a light emitter that emits light, and a receiver that receives response information indicating that an operator who operates the moving body, an observer who observes the moving body, or a supervisor who supervises the moving body sees the light. The moving body also includes a detector that detects a position of the moving body, a recorder that records the position of the moving body, and a controller that, when the receiver receives the response information within a fixed time since the light emitter emitted the light, causes the recorder to record the detected position of the moving body, and when the receiver does not receive the response information within the fixed time, outputs to the drive a control command that causes the moving body to move to the last recorded position.
