Solution Overview

Problem

Existing wireless communication systems face challenges in maintaining uninterrupted communication between a control center and a moving object, especially in areas with obstacles, and struggle to optimize the movement path of the moving object due to limited horizontal or vertical movement capabilities of existing solutions like Google's Loon project and Cisco's NERV.

Innovation Solution

An unmanned device equipped with a surrounding environment information detector and processor generates control commands for the moving object, including movement paths, speeds, and target points, using LIDAR sensors and cameras to relay communication and control the movement of the object, even in obstructed areas, by deriving optimal paths and storing similar environmental data for efficient navigation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If a hot-air balloon is used to provide wireless communication in wide areas, then the coverage area is improved, but horizontal or vertical movement is limited

Engineering Contradiction:
Improvecoverage areaVSAvoidmovement capability
Core Design Contradiction:
Area of stationary objectVSEase of operation

Solution Approach 1:

The unmanned device is designed to perform multiple functions: it provides wireless communication relay services while simultaneously possessing autonomous flight capabilities with horizontal and vertical movement. This multi-functional design resolves the contradiction by making a single system that can both cover wide areas and move freely within three-dimensional space.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Productivity

If a network emergency response vehicle is used to provide wireless communication in disaster areas, then wireless communication services are provided quickly, but it consumes a lot of time due to ground movement limitations

Engineering Contradiction:
Improveservice deployment speedVSAvoidtime consumption
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent replaces the ground-based mechanical vehicle system with an aerial unmanned device that flies in three-dimensional space. This substitution eliminates the time-consuming ground movement constraints while maintaining the ability to quickly deploy wireless communication services in disaster areas.

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

3Device complexity

If direct wireless communication is attempted between control center and moving object in obstacle areas, then communication simplicity is maintained, but communication interruption occurs

Engineering Contradiction:
Improvecommunication system simplicityVSAvoidcommunication continuity
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The unmanned device acts as an intermediary relay node between the control center and the moving object. When direct communication is blocked by obstacles, the unmanned device transmits data packets between the two endpoints, ensuring communication continuity while maintaining relatively simple system architecture.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Reliability

If the unmanned device relays communication between control center and moving object, then communication reliability is improved, but device complexity increases

Engineering Contradiction:

Solution Approach 1:

The unmanned device integrates multiple functions including wireless communication relay, obstacle detection, path planning, and movement control into a single platform. This multi-functional integration achieves reliable communication in obstacle areas while managing system complexity through consolidation rather than adding separate dedicated systems.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

An unmanned device used in a wireless communication relay system includes: a surrounding environment information detector acquiring information on a surrounding environment of a moving object; a processor generating a control command for the moving object based on the acquired information on the surrounding environment; and a communication interface for transmitting the control command generated by the processor to the moving object, wherein the unmanned device is located at a predetermined height and relays communication between the moving object and a control center, and thus, even when wireless communication between the control center and the moving object is difficult due to an obstacle or the like, the connection of the wireless communication may be maintained without disconnection of the wireless communication.
