Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current WLAN systems face malfunctions due to hardware/software failures in access points or network configuration errors, leading to disrupted LAN functionality and degraded user experience. Existing fault detection and reporting mechanisms are inefficient, requiring terminals to wait for timeouts to recognize anomalies.

Innovation Solution

A network state detection and feedback mechanism is implemented using a gateway device, which autonomously performs proactive or passive network detection. The gateway device determines the network state and communicates abnormal conditions efficiently to LAN-side terminals, allowing for immediate action.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If terminals wait for timeouts to detect network anomalies, then the detection mechanism is simple, but the response time is long and user experience is degraded

Engineering Contradiction:

Improvetime to detect network anomalyVSAvoidcomplexity of detection mechanism

Core Design Contradiction:

Loss of timeVSDevice complexity

Solution Approach 1:

The gateway device continuously monitors network status and provides feedback information to terminals about network health. This feedback mechanism allows terminals to understand network state without implementing complex detection systems themselves, resolving the contradiction between fast detection and simple mechanism.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The gateway device acts as an intermediary between the network and terminals. It performs network status detection on the WAN side and reports this information to LAN-side terminals, enabling fast anomaly detection without requiring terminals to implement complex detection mechanisms.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If the gateway device performs proactive network state detection, then network anomaly detection speed is improved, but the device complexity and processing load increase

Engineering Contradiction:

Improvenetwork anomaly detection speedVSAvoidcomplexity of gateway detection function

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The gateway device autonomously performs network status detection and automatically reports to terminals without requiring manual intervention or complex configuration. This self-service approach improves detection speed while keeping the implementation relatively simple through automated operations.

Inventive Principle:

Principle #25Self-service

3Reliability

If the gateway reports network status to terminals, then user experience is improved through faster anomaly identification, but the network traffic and processing load increase

Engineering Contradiction:

Improvenetwork reliability and user experienceVSAvoidprocessing load and network traffic

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

The gateway device performs network status detection periodically rather than continuously, reporting status at intervals. This periodic action maintains network reliability and user experience while reducing processing load and network traffic compared to constant monitoring and reporting.

Inventive Principle:

Principle #19Periodic action
