Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing methods for file transfer between devices, such as PCs and mobile phones, often rely on wired connections, which limit user convenience and ease of operation.

Innovation Solution

A terminal interaction method that uses a local Web server to facilitate file transfers between IM terminals by generating and sharing URL address information, allowing files to be exchanged securely and conveniently over a network, even if the devices are not on the same LAN, through the use of a hub device when necessary.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a wired connection (e.g., USB cable) is used to establish a communication channel between PC and mobile phone, then the connection stability is improved, but the ease of operation deteriorates

Engineering Contradiction:

Improveconnection stabilityVSAvoiduser convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces the mechanical wired connection (USB cable) with a wireless network-based communication system. The file transfer function is implemented through network protocols and web server technology, eliminating the need for physical cable connections while maintaining reliable data transmission between devices.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces a web server as an intermediary component that facilitates file transfer between devices over the network. The web server acts as a mediator that receives file requests, manages file transmission, and coordinates communication between the sending and receiving devices, enabling seamless wireless file sharing.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If a local Web server is started to enable file transfer over network, then the ease of operation is improved, but the device complexity increases

Engineering Contradiction:

Improvewireless file transfer capabilityVSAvoidsystem structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent implements a web server that provides multiple functions including file hosting, request handling, and network communication. This single component serves universal purposes: it can handle different file types, support multiple clients simultaneously, and provide both upload and download capabilities, reducing the need for separate specialized components.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The web server automatically manages file transfer operations without requiring manual intervention. It self-configures network connections, automatically responds to file requests, handles authentication, and manages data transmission protocols, thereby simplifying the user interface while managing the underlying complexity internally.

Inventive Principle:

Principle #25Self-service

3Adaptability or versatility

If URL address information is generated and shared via IM platform, then the adaptability is improved, but the loss of information increases

Engineering Contradiction:

Improvenetwork environment compatibilityVSAvoidconnection reliability

Core Design Contradiction:

Adaptability or versatilityVSLoss of information

Solution Approach 1:

The system implements feedback mechanisms where the web server confirms URL generation to the IM platform, and the IM platform verifies successful transmission of address information to the receiving device. This feedback loop ensures that critical information is properly delivered and acknowledged, reducing information loss while maintaining adaptability across different network environments.

Inventive Principle:

Principle #23Feedback

AI summary

This provides a terminal interaction method, device, and system. The method includes: a first IM terminal receiving a user-entered file transfer command directed to a second IM terminal, the two terminals logged into an IM platform using associated account numbers, determining whether the two terminals belong to a same LAN, if yes, starting a local Web server of the first IM terminal and generating URL address information of a file, transmitting, to the second IM terminal, address information of the local Web server and the URL address information of the file, the second IM terminal transmitting, in accordance with the address information of the local Web server, to the local Web server, a file obtaining request including the URL address information of the file, and the local Web server obtaining and transmitting the file to the second IM terminal in accordance with the URL address information of the file.
