Solution Overview

Problem

Conventional wireless communication systems inaccurately determine communication quality due to interference from other radio waves, neglecting the impact of reflected waves and external environmental changes, leading to suboptimal channel selection and potential communication errors.

Innovation Solution

A wireless communication system that detects characteristic data for each channel, generates first and second evaluation data to assess communication quality, and determines channel deterioration based on these data types, excluding channels with deteriorated quality to ensure reliable communication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the wireless communication system uses a single threshold for determining communication quality, then the determination process is simple, but the accuracy of communication quality assessment deteriorates due to inability to distinguish between temporary fluctuations and actual deterioration

Engineering Contradiction:
Improvecommunication quality assessment accuracyVSAvoidevaluation data structure
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent segments the evaluation of communication quality into two distinct evaluation data types: first evaluation data with lower responsiveness and second evaluation data with higher responsiveness. This segmentation allows the system to differentiate between temporary fluctuations and actual deterioration, improving assessment accuracy while maintaining a manageable evaluation structure through defined selection criteria.

Inventive Principle:
Principle #1Segmentation

2Speed

If the system responds rapidly to changes in characteristic data, then the responsiveness to communication quality changes improves, but the reliability of determination deteriorates due to potential false positives from temporary fluctuations

Engineering Contradiction:
Improveresponsiveness to communication quality changesVSAvoiddetermination reliability
Core Design Contradiction:
SpeedVSReliability

Solution Approach 1:

The patent implements a dynamic determination mechanism that adapts the selection of evaluation data based on current communication conditions. The system dynamically chooses between first and second evaluation data according to predefined selection criteria, enabling flexible response that balances speed and reliability - using responsive second evaluation data when appropriate while avoiding false positives through criterion-based filtering.

Inventive Principle:
Principle #15Dynamics

3Reliability

If the system excludes channels based on temporary fluctuations, then the communication reliability improves by avoiding actual deteriorated channels, but the productivity deteriorates due to unnecessary channel exclusions

Engineering Contradiction:
Improvecommunication reliabilityVSAvoidchannel utilization efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent employs a feedback mechanism where the system continuously monitors communication quality and uses selection criteria to determine whether to exclude channels. By providing feedback loops that consider both first and second evaluation data, the system makes informed decisions about channel exclusion, avoiding unnecessary exclusions of usable channels while reliably identifying and excluding actually deteriorated channels.

Inventive Principle:
Principle #23Feedback

AI summary

A wireless communication system, which performs wireless communication between a master device and a slave device, is configured to: detect characteristic data indicating a communication quality of wireless communication for each communication channel; generate, for each communication channel, first evaluation data and second evaluation data, based on the detected characteristic data, the second evaluation data having a higher responsiveness to a change occurred in the characteristic data compared with the first evaluation data; determine deterioration of the communication quality for each communication channel based on the first evaluation data and the second evaluation data; decide one communication channel whose communication quality is determined to be deteriorated as a communication channel to be excluded from the multiple communication channels for performing the wireless communication.
