Solution Overview

Problem

Current methods for investigating radio interference in wireless communication are time-consuming and require physical presence, making it difficult for users to quickly determine and take action against interference effects.

Innovation Solution

An information output device that receives quality information from wireless communication means, estimates radio interference occurrence, acquires alternative communication information from a storage, and outputs information for switching to an alternative communication method to mitigate interference.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If an investigator goes to the scene to investigate radio interference, then the investigation can be performed, but the process becomes time-consuming

Engineering Contradiction:

Improveradio interference investigation accuracyVSAvoidinvestigation time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The wireless communication device performs self-diagnosis by automatically measuring communication quality metrics (throughput, packet error rate, bit error rate) and determining whether radio interference is occurring, eliminating the need for external investigators to travel to the scene

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces the mechanical process of physical investigation with electronic automated measurement and analysis, using software algorithms to process communication quality data and determine interference occurrence without human intervention

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If traditional investigation methods are used, then radio interference can be detected, but users cannot quickly determine action to take against interference effects

Engineering Contradiction:

Improveradio interference detection accuracyVSAvoiduser actionability

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system provides feedback to the user by not only detecting radio interference but also recommending specific countermeasures (changing communication partners, switching frequencies, changing locations), enabling users to take immediate action based on the detection results

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent introduces an intermediary processing layer that analyzes communication quality data, determines interference occurrence, and generates actionable recommendations, bridging the gap between raw data and user decision-making

AI summary

An information output device receives, for an in-use communication being a wireless communication used by wireless communication means for performing wireless communication, quality information being information about quality of the in-use communication from the wireless communication means, estimates occurrence of radio interference on the in-use communication, based on the quality information, acquires alternative communication information from storage means when occurrence of the radio interference on the in-use communication is estimated, and outputs output information including the alternative communication information. The storage means stores communication information being information about a wireless communication for each wireless communication available to the wireless communication means. The alternative communication information is the communication information of an alternative communication being a wireless communication available to the wireless communication means in place of the in-use communication.
