Solution Overview

Problem

The communication delay between electronic devices is high due to the need for discovery and authentication before service communication, affecting user experience.

Innovation Solution

A device networking method that establishes a first communication connection with a second electronic device using multiple communication manners, determines the validity of the connection based on received packets, and performs service communication without repeated keepalive checks, thereby reducing delays and improving reliability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If discovery and authentication are performed before service communication, then connection reliability is improved, but communication delay increases

Engineering Contradiction:
Improveconnection reliabilityVSAvoidcommunication delay
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by establishing multiple communication connections (first communication connection and second communication connection) between electronic devices before service communication is needed. The first connection is set up through discovery and authentication in advance, while the second connection provides an alternative pathway. This allows devices to skip repeated discovery and authentication processes during subsequent service communications, thereby reducing communication delay while maintaining connection reliability through redundant connection paths.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If keepalive checks are performed before each service communication, then connection validity is ensured, but communication efficiency deteriorates

Engineering Contradiction:
Improveconnection validityVSAvoidcommunication efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent extracts the keepalive check mechanism from the service communication process itself. Instead of performing keepalive checks before each service communication, the system maintains connection validity through background heartbeats or connection state tracking. This separation allows service communication to proceed without being blocked by repeated validity checks, thereby improving communication efficiency while still ensuring connection reliability through the extracted keepalive mechanism operating independently.

Inventive Principle:
Principle #2Taking out (Extraction)

3Reliability

If multiple communication manners are established, then communication reliability is improved, but device complexity increases

Engineering Contradiction:
Improvecommunication reliabilityVSAvoidconnection management complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces a connection management module or intermediary layer that handles the complexity of managing multiple communication connections. This intermediary abstracts the detailed management of the first communication connection and second communication connection, providing a simplified interface for service communication. By placing this intermediary layer between the multiple connections and the service communication logic, the system can maintain high reliability through multiple communication pathways while reducing the perceived complexity for applications that need to communicate.

Inventive Principle:
Principle #24Intermediary (Mediator)
