Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Users of X-ray imaging systems using the 5 GHz frequency band often mistake communication disruptions caused by the DFS function as system abnormalities, due to lack of notification for channel changes made to avoid interference with meteorological radars.

Innovation Solution

An X-ray imaging system that includes a determination unit to detect interference and an output unit to notify users when communication is stopped due to DFS function, allowing for channel changes and displaying notifications to differentiate the cause of the disruption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If the DFS function is implemented to avoid interference with meteorological radar, then interference with specific devices is avoided, but communication is disabled without user notification causing confusion

Engineering Contradiction:

Improveinterference with meteorological radarVSAvoiduser awareness of communication status

Core Design Contradiction:

Object-affected harmful factorsVSLoss of information

Solution Approach 1:

The system implements feedback by notifying the user when communication is disabled due to DFS function activation. The notification mechanism provides real-time information about the communication status change, allowing users to understand that the disconnection is due to radar interference avoidance rather than system failure.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The notification system acts as an intermediary between the DFS function and the user. When the DFS function detects meteorological radar interference and disables communication, the notification mechanism mediates by conveying this status change to the user, bridging the gap between the automated interference avoidance mechanism and human awareness.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If the AP changes channel to avoid interference, then interference with meteorological radar is avoided, but user confusion occurs due to lack of notification

Engineering Contradiction:

Improveinterference with meteorological radarVSAvoiduser understanding of system behavior

Core Design Contradiction:

Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The notification system provides feedback to users when the AP changes channels due to DFS function activation. This feedback mechanism explains the reason for communication disruption, improving user understanding of system behavior and reducing confusion about whether the system is functioning normally.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system performs preliminary notification before or during the channel change process. By notifying users in advance or simultaneously with the DFS-induced communication disruption, users can understand the upcoming or ongoing channel change, making the system behavior more predictable and easier to operate with.

Inventive Principle:

Principle #10Preliminary action
