Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing wireless communication systems require user intervention to recover from errors in wireless connections with external access points, which is time-consuming and inconvenient, and existing solutions do not provide a method for automatic recovery.

Innovation Solution

An electronic apparatus with a processing unit that performs self-repair and reboot by uninstalling and reinstalling driver software for the wireless communication unit when an error occurs in the wireless connection, allowing for automatic recovery without user intervention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If user operation is used to redo wireless setting for error recovery, then wireless connection error can be resolved, but user time and effort are consumed

Engineering Contradiction:

Improvewireless connection recoveryVSAvoiduser time and effort

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The electronic apparatus performs automatic self-diagnosis and self-repair of wireless connection errors by detecting connection status and autonomously executing recovery procedures without requiring user intervention, thereby resolving the contradiction between reliable error recovery and minimizing user time consumption

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system pre-configures recovery procedures and automatically executes them when errors are detected, performing the necessary actions before user intervention would be required, thus eliminating user time loss while maintaining reliable error recovery

Inventive Principle:

Principle #10Preliminary action

2Extent of automation

If driver software is uninstalled and reinstalled for self-repair, then wireless connection error is resolved automatically, but device complexity increases

Engineering Contradiction:

Improveautomatic error recoveryVSAvoidsoftware management complexity

Core Design Contradiction:

Extent of automationVSDevice complexity

Solution Approach 1:

The processing unit automatically performs driver software uninstallation and reinstallation as a self-repair mechanism when wireless connection errors are detected, achieving high extent of automation through embedded software management capabilities that handle the complexity internally without increasing user-facing device complexity

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The processing unit acts as an intermediary that manages the complexity of driver software operations, shielding the user from complex software management tasks while enabling automatic recovery through controlled software uninstallation and reinstallation processes

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

An electronic apparatus includes: a wireless communication unit wirelessly communicating with an external access point; and a processing unit performing communication control for the wireless communication unit. The processing unit performs uninstallation of driver software causing the wireless communication unit to operate and installation of the driver software after the uninstallation, as a self-repair and reboot, when there is an error in wireless connection with the external access point.
