Solution Overview

Problem

The existing radiation imaging systems face instability in communication between the radiation imaging apparatus and the control apparatus due to the lack of examination in assigning unique wireless identification information, leading to multiple devices sharing the same communication ID, which can result in impossible or unstable communication.

Innovation Solution

A method is introduced where the control apparatus determines the presence of a master unit in the system and assigns unique wireless identification information, such as a generated SSID, to radiation imaging apparatuses operating as access points, ensuring each device has a distinct ID for stable communication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the radiation imaging apparatus operates as an access point (AP) to reduce system components, then the number of system components is reduced, but communication stability deteriorates due to potential duplicate wireless communication IDs

Engineering Contradiction:
Improvenumber of system componentsVSAvoidcommunication stability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The control apparatus performs preliminary examination to determine whether another radiation imaging apparatus is operating as an AP before allowing the current apparatus to operate as an AP. This preliminary check prevents duplicate SSID assignments that would cause communication instability, while still allowing the apparatus to function as an AP when appropriate, thus maintaining system simplicity.

Principle #10Preliminary action

2Ease of operation

If wireless communication ID assignment is not examined, then the system operation is simple, but communication reliability deteriorates due to possible duplicate IDs

Engineering Contradiction:
Improvesystem operation simplicityVSAvoidcommunication reliability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The control apparatus receives feedback information from the radiation imaging apparatus indicating whether another apparatus is operating as an AP. Based on this feedback, the control apparatus automatically determines whether to allow the current apparatus to operate as an AP and assigns an appropriate SSID. This automated feedback mechanism maintains communication reliability without requiring complex manual configuration or examination procedures.

AI summary

A radiation imaging system includes a radiation imaging apparatus capable of operating as a master unit or a slave unit in wireless communication, and a control apparatus capable of controlling an operation of the radiation imaging apparatus. The control apparatus includes a determination unit configured to determine whether a device operating as the master unit of the wireless communication exists in the radiation imaging system, and a control unit configured to control the operation of the radiation imaging apparatus based on the determination. The control unit controls the operation of the radiation imaging apparatus based on the determination such that one master unit of the wireless communication exists in the radiation imaging system.
