Solution Overview

Problem

Existing control terminal systems disrupt user experience by requiring interruption of controlled devices, such as drones and balance vehicles, when control needs to be transferred, as they lack seamless switching methods.

Innovation Solution

A control switching method that involves sending a request to a server for control transfer, receiving a notification from the server after agreement from the current control terminal, and establishing a communication connection with the controlled device, allowing smooth transfer of control without interrupting the device's operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If control terminal switches by interrupting operation, then control terminal can be changed, but operation of controlled device is interrupted

Engineering Contradiction:
Improvecontrol terminal switchingVSAvoidcontinuous operation
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The system performs preliminary actions by establishing a communication connection between the second control terminal and the controlled device before the first control terminal disconnects. The server coordinates this by sending a connection instruction to the controlled device, enabling the second control terminal to connect in advance, thus ensuring continuous operation during control terminal switching.

Inventive Principle:
Principle #10Preliminary action

2Ease of operation

If control terminal switches without interruption, then user experience is improved, but communication connection establishment becomes complex

Engineering Contradiction:
Improveuser experienceVSAvoidcommunication connection establishment
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The server acts as an intermediary to coordinate the control terminal switching process. It receives the first control terminal's agreement notification, sends a connection instruction to the controlled device, and manages the handover process. This intermediary role simplifies the overall process by centralizing coordination, reducing the complexity that would otherwise be distributed across multiple direct communications.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

The present invention relates to a control switching method, a control terminal, a computer program and a recording medium, which enable control of a controlled device to be switched. The control switching method comprises: sending (S11) a request for controlling the controlled device to a server, wherein the server, after receiving the request, requests a first control terminal, which controls the controlled device at present, to transfer control; receiving (S12) a notification, sent by the server, of authorizing to control the controlled device, wherein the notification is sent after the server determines that the first control terminal agrees to transfer control; and connecting (S13) communicatively with the controlled device to control the controlled device.
