Solution Overview

Problem

Current mobile electronic devices face challenges in establishing efficient application-related communication, media sharing, and contact list management, particularly in group purchasing, photo/video sharing, and playlist management, due to limitations in data transfer, user interface complexity, and the need for physical connections.

Innovation Solution

A method and system for mobile electronic devices to scan for nearby devices, establish wireless communication using phrase packets, and authenticate to enable application-related communication, media sharing, and contact list management through proximity-based protocols like Bluetooth, WiFi Direct, or NFC, allowing for seamless group purchasing, photo/video sharing, and virtual playlist creation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If mobile electronic devices use conventional data transfer methods requiring physical connections, then data transfer reliability is improved, but device complexity and ease of operation deteriorate

Engineering Contradiction:

Improvedata transfer reliabilityVSAvoidconnection complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces physical mechanical connections (cables, ports) with wireless communication protocols (Bluetooth, WiFi Direct, NFC). This substitution eliminates the need for physical plugging and unplugging while maintaining data transfer reliability through protocol-based authentication and connection management.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces phrase packets as intermediary carriers that encapsulate device identities and authentication information. These packets serve as mediators that enable wireless devices to establish trusted connections without physical contact, resolving the contradiction between wireless convenience and connection reliability.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If mobile electronic devices establish wireless communication without authentication, then ease of operation is improved, but security and reliability deteriorate

Engineering Contradiction:

Improveconnection easeVSAvoidcommunication security

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent performs authentication actions before establishing the actual data communication channel. Devices exchange phrase packets containing authentication information during the connection establishment phase, ensuring security is validated beforehand. This preliminary authentication maintains ease of operation while guaranteeing communication security.

Inventive Principle:

Principle #10Preliminary action

3Manufacturing precision

If mobile electronic devices require manual contact list updates, then data accuracy is improved, but productivity and ease of operation deteriorate

Engineering Contradiction:

Improvecontact list accuracyVSAvoidcontact list update efficiency

Core Design Contradiction:

Manufacturing precisionVSProductivity

Solution Approach 1:

The patent enables contact list information to be automatically synchronized between devices through wireless communication. When devices are connected via phrase packet authentication, contact information is automatically exchanged and updated without requiring manual input from users, thereby maintaining accuracy while dramatically improving update efficiency.

Inventive Principle:

Principle #25Self-service

4Ease of operation

If mobile electronic devices use proximity-based wireless communication, then ease of operation is improved, but measurement precision and device identification accuracy deteriorate

Engineering Contradiction:

Improvedevice discovery easeVSAvoiddevice identification accuracy

Core Design Contradiction:

Ease of operationVSMeasurement precision

Solution Approach 1:

The patent changes the identification parameter from simple signal strength or proximity detection to encapsulated device identities within phrase packets. This allows precise device identification and differentiation even among multiple nearby devices, maintaining ease of operation while improving identification accuracy through structured data exchange.

Inventive Principle:

Principle #35Parameter changes

AI summary

When a host mobile electronic device and a client mobile electronic device connect to each other for at least a second time, the client mobile electronic device refers to an entry corresponding to the host mobile electronic device for retrieve required information to wirelessly connect to the host mobile electronic device and to connect to an application installed on the host mobile electronic device under authentication. Therefore, the client mobile electronic device can be relieved from the burden of requesting required information for authentication repeatedly.
