Solution Overview

Problem

Existing electronic whiteboards lack flexibility in data sharing capabilities, limiting their application range and requiring external servers for interactive data synchronization.

Innovation Solution

A data sharing method that enables an electronic whiteboard to start a web service and synchronization server, transmitting user operation information directly to connected mobile terminals without relying on external servers, allowing for real-time sharing of writing, erasing, canvas translation, zooming, and background modification.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If an electronic whiteboard uses traditional interactive sharing through network server, then data sharing function is achieved, but device complexity and deployment difficulty increase due to requiring external servers

Engineering Contradiction:

Improvedata sharing capabilityVSAvoidsystem structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent extracts the server functionality from the external network infrastructure and embeds it directly into the electronic whiteboard device. The whiteboard now contains an embedded server that can independently provide data sharing services without requiring external server infrastructure, thereby reducing system complexity while maintaining data sharing capabilities.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces a local web server as an intermediary between the electronic whiteboard and mobile terminals. This web server acts as a bridge that enables direct communication and data sharing between devices through local network protocols, eliminating the need for external network servers while maintaining the data sharing function.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If an electronic whiteboard requires external servers for data synchronization, then interactive sharing is achieved, but ease of operation deteriorates due to complex deployment requirements

Engineering Contradiction:

Improvedata synchronizationVSAvoiddeployment process

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The electronic whiteboard performs self-service by embedding the server functionality within itself. The device automatically starts the web server when launched, requiring no external server configuration or deployment. Users simply need to open a web browser on their mobile devices and access the local network address to begin using the data sharing function immediately.

Inventive Principle:

Principle #25Self-service

3Adaptability or versatility

If an electronic whiteboard implements comprehensive data sharing functions, then application range expands, but device complexity increases due to additional hardware requirements

Engineering Contradiction:

Improveapplication rangeVSAvoidhardware configuration

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent makes the electronic whiteboard universal by enabling it to function as both a traditional writing device and a web server simultaneously. The same hardware resources (processor, memory, network interface) are used to serve multiple functions including local web serving, data synchronization, and interactive sharing, thereby expanding application range without adding dedicated hardware for each function.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A data sharing method, which is used for an electronic whiteboard, and includes: controlling the electronic whiteboard to start a web service and a synchronization server in response to the electronic whiteboard starting a target application; receiving a user input to determine a user operation, and caching user operation information; and transmitting, via the synchronization server, the user operation information to a mobile terminal that accesses the web service.
