Solution Overview

Problem

Current remote synchronization control technologies lack support for simultaneous monitoring of multiple independent terminals, particularly in the mobile Internet environment, leading to interaction conflicts and high network bandwidth occupation.

Innovation Solution

A mobile terminal-based star topology structure is introduced, utilizing an authorization token for coordination interaction control between a master controlling terminal and multiple controlled terminals, with tile division and image compression to reduce network bandwidth usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional remote synchronization control software is used, then control functionality between terminals is achieved, but support for simultaneous monitoring of multiple independent terminals is lacking

Engineering Contradiction:
Improvesupport for multiple independent terminalsVSAvoidsystem architecture complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces a master controlling terminal as an intermediary that coordinates control among multiple controlled terminals. The master terminal receives control instructions from a current controlled terminal and distributes them to other controlled terminals, enabling multi-terminal support without requiring complex peer-to-peer coordination between all terminals.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If multiple controlled terminals are connected to master controlling terminal, then simultaneous monitoring capability is achieved, but interaction conflicts occur between controlled terminals

Engineering Contradiction:
Improvesimultaneous monitoring capabilityVSAvoidinteraction conflict
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent implements preliminary action by establishing a token acquisition mechanism before control operations. A controlled terminal must acquire a token from the master controlling terminal before it can send control instructions. This preliminary token acquisition prevents interaction conflicts by ensuring only authorized terminals can issue commands at any given time.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The master controlling terminal provides feedback by managing token distribution and revocation based on control requests. When a controlled terminal requests control, the master terminal responds by granting or denying token access, thereby regulating interactions and preventing conflicts through centralized feedback control.

Inventive Principle:
Principle #23Feedback

3Adaptability or versatility

If synchronization control is implemented across multiple terminals, then remote control functionality is achieved, but network bandwidth occupation increases

Engineering Contradiction:
Improveremote control functionalityVSAvoidnetwork bandwidth occupation
Core Design Contradiction:
Adaptability or versatilityVSLoss of energy

Solution Approach 1:

The patent extracts and transmits only essential control elements (tokens) rather than duplicating full control sessions across all terminal pairs. By extracting the critical authorization component and transmitting it selectively through the master terminal, the system reduces network bandwidth consumption while maintaining remote control functionality across multiple terminals.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

A terminal and a synchronization control method among terminals are provided. The method includes: a master controlling terminal establishing synchronization control connections with multiple controlled terminals respectively; the master controlling terminal delivering a unique authorization token held by the master controlling terminal to one controlled terminal among the multiple controlled terminals, to enable the current controlled terminal acquiring the authorization token to be capable of performing information interaction with the master controlling terminal for synchronization control processing. The solution can solve the problem of coordination interaction control between a master controlling terminal and multiple mutually independent controlled terminals, and avoid interaction conflict between the mutually independent controlled terminals. Moreover, the solution can further reduce the network bandwidth occupation and solve the problem of high network bandwidth occupation.
