Solution Overview

Problem

Existing methods for sharing context information among electronic devices involve central servers, leading to latency and costs, and lack direct peer-to-peer communication solutions.

Innovation Solution

Electronic devices equipped with dual communication modules and processors enable direct connection to a shared access point based on matching account information, allowing peer-to-peer data sharing without a central server.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If context information is shared using a central server, then data sharing is enabled among electronic devices, but latency occurs when obtaining context information and server usage costs money

Engineering Contradiction:
Improvedata sharing capabilityVSAvoidlatency
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent extracts the central server from the data sharing process and replaces it with direct peer-to-peer communication between electronic devices through access point lists. Devices share access point information and connect directly to each other, eliminating the intermediary server that causes latency and costs.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces access point lists as a new intermediary mechanism. Instead of using a central server for data sharing, devices exchange access point information and use these lists as mediators to establish direct connections, thereby reducing latency while maintaining data sharing capability.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If context information is shared using a central server, then data sharing is enabled among electronic devices, but server usage costs money

Engineering Contradiction:
Improvedata sharing capabilityVSAvoidcost
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The patent removes the central server from the system architecture and replaces server-based data sharing with direct device-to-device communication through shared access point lists, eliminating server usage costs while preserving data sharing functionality.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

Electronic devices perform data sharing autonomously by exchanging access point information and connecting directly to each other without requiring external server resources. Each device serves itself and other devices in the network, eliminating dependency on paid server infrastructure.

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If electronic devices connect to different access points, then devices can maintain independent connections, but direct peer-to-peer communication is not established

Engineering Contradiction:
Improveindependent connection capabilityVSAvoiddirect communication
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent merges access point lists from multiple devices and identifies common access points that both devices can use. By combining the connection options from both devices and selecting a shared access point, the system enables direct peer-to-peer communication while respecting each device's independent connection capabilities.

Inventive Principle:
Principle #5Merging (Combining)
