Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional tablet computers lack the convenience of data transfer between devices, as the stylus can only perform cut, copy, and paste functions within a single machine, requiring users to search for network connections to move files between machines, thus losing the handwriting interface advantage.

Innovation Solution

A method involving a stylus that generates and transfers a transmission identification code from one tablet computer to another, allowing seamless data transfer between devices by matching and verifying the stylus identification code, enabling the second computer to obtain the data based on the code.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the stylus is used for data transfer between different computers, then the convenience of handwriting-based operation is improved, but the device complexity increases due to the need for transmission identification codes and wireless communication mechanisms

Engineering Contradiction:

Improvehandwriting-based data transfer convenienceVSAvoidtransmission identification code mechanism

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The stylus serves as an intermediary device between the first and second computers. It contains a wireless transmission module that can communicate with both computers, and a storage module that holds the transmission identification code. This intermediary approach allows data transfer between computers while maintaining the simplicity of the stylus interface for users.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The stylus is designed with multi-functionality, serving both as a traditional input device for handwriting recognition and as a data transfer medium between computers. By integrating a wireless transmission module and storage capability into the stylus, it can perform both its traditional function and the new data transfer function, eliminating the need for separate transfer mechanisms.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If network space search is performed to transfer files between machines, then the data transfer capability between different computers is improved, but the ease of operation deteriorates as users must manually search and configure network connections

Engineering Contradiction:

Improvedata transfer capability between computersVSAvoidmanual network connection configuration

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system performs self-service by automatically generating and transferring the transmission identification code between computers through the stylus. The first computer generates the code, the stylus automatically receives and stores it, and the second computer automatically retrieves and uses it - all without requiring manual network configuration or user intervention in the transfer process.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The transmission identification code is generated in advance on the first computer before the actual data transfer operation. This preliminary generation of the transfer code enables the second computer to immediately access and retrieve data without requiring real-time network search or configuration during the data transfer process.

Inventive Principle:

Principle #10Preliminary action
