Solution Overview

Problem

Current methods for file sharing in multi-user scenarios, particularly on mobile devices, are complex and do not effectively provide network access, as they require additional devices and operations like Bluetooth matching and wireless router setups, which increase user difficulty and do not meet current network access needs.

Innovation Solution

A data processing method and device utilizing a multimedia interface with both P2P station and soft AP network interfaces, where service data is transmitted using determined radio frequency channels, either alternately in time division or in allocated time slices, and frequency bands are switched when interfered, to facilitate easy and convenient file sharing and network access.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If Bluetooth is used for file sharing, then file sharing capability is provided, but operation complexity increases due to searching and matching requirements

Engineering Contradiction:
Improvefile sharing capabilityVSAvoidoperation complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent divides the network interface into two distinct types: P2P station network interface for direct device-to-device file sharing, and soft AP network interface for providing network access. This segmentation allows the system to handle different scenarios (direct sharing vs. network access) through dedicated interfaces, simplifying user operations by automatically selecting the appropriate interface type based on service requirements.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If a wireless router with projection functionality is used, then file sharing is enabled, but device complexity increases due to additional hardware requirements

Engineering Contradiction:
Improvefile sharing capabilityVSAvoiddevice structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements multi-functionality by enabling the mobile phone to perform both P2P file sharing and soft AP network access functions using its existing wireless communication capabilities. The system can dynamically switch between P2P station mode and soft AP mode, making the mobile phone itself serve as both a file sharer and a network access point, eliminating the need for additional projection devices or wireless routers.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Use of energy by moving object

If P2P service and soft AP service use the same frequency band, then radio frequency resources are utilized efficiently, but signal interference occurs between services

Engineering Contradiction:
Improveradio frequency resource utilizationVSAvoidsignal interference
Core Design Contradiction:
Use of energy by moving objectVSObject-affected harmful factors

Solution Approach 1:

The patent implements periodic action through time-division multiplexing, where the system alternates between P2P service and soft AP service in different time slots. When P2P service is active, it uses the radio frequency channel; when soft AP service is active, it uses the same channel. This periodic switching allows efficient utilization of radio frequency resources while preventing signal interference between the two services by ensuring they do not operate simultaneously on the same frequency.

Inventive Principle:
Principle #19Periodic action
