Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple applications operate in cooperation with each other, then system functionality and versatility are improved, but information mismatch occurs when applications disconnect and reconnect

Engineering Contradiction:

Improvecooperation between applicationsVSAvoidinformation mismatch

Core Design Contradiction:

Adaptability or versatilityVSLoss of information

Solution Approach 1:

The system performs preliminary actions by establishing a notification queue before disconnection occurs. When applications disconnect, the notification queue preserves the sequence and state of control notifications, ensuring that information is not lost during reconnection. This preliminary preparation of the notification queue resolves the information mismatch problem while maintaining application cooperation versatility.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The notification queue acts as an intermediary between the first and second applications. It receives control notifications from one application and delivers them to the other, maintaining information integrity during disconnection and reconnection events. This intermediary mechanism enables continuous cooperation between applications while preventing information mismatch.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If remote desktop mechanisms are used to enable multi-terminal operation, then ease of operation is improved, but cooperation between applications with different GUIs and OSs cannot be achieved

Engineering Contradiction:

Improvemulti-terminal operationVSAvoidcooperation between different applications

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The notification queue mechanism provides a universal interface that works across different GUIs and operating systems. Instead of relying on remote desktop mechanisms that are platform-specific, the system uses a standardized notification queue that can transmit control information between any applications regardless of their underlying platform, achieving both ease of operation and broad adaptability.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system replaces the mechanical remote desktop mechanism with a software-based notification queue system. This substitution eliminates the limitations of remote desktop technology regarding cross-platform compatibility, allowing applications with different GUIs and OSs to cooperate seamlessly through standardized notification transmission.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Loss of information

If all control notifications are transmitted during reconnection, then information completeness is improved, but system performance and responsiveness deteriorate

Engineering Contradiction:

Improveinformation completenessVSAvoidsystem responsiveness

Core Design Contradiction:

Loss of informationVSProductivity

Solution Approach 1:

The system extracts and transmits only the essential control notifications from the notification queue during reconnection, rather than transmitting all notifications indiscriminately. This selective extraction maintains information completeness for critical operations while filtering out redundant information, thereby preserving system responsiveness and performance during reconnection events.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The system applies partial action by transmitting a subset of necessary control notifications rather than all notifications. This approach provides just enough information to restore application state and functionality without overwhelming the system with excessive data transmission, thus maintaining responsiveness while ensuring information completeness for critical operations.

Inventive Principle:

Principle #16Partial or excessive action

AI summary

A radiation imaging system that can control a radiation generating apparatus and a radiation detector based on communication between a first control application and a second control application, the system comprises: a connection monitoring unit configured to monitor a connection state of the communication; a holding unit configured to hold an information notification indicating a control state of an imaging control unit of the first control application that performs the control in a case where the connection monitoring unit determines that the connection state is a disconnection state; and a deletion processing unit configured to perform deletion processing of an information notification held in the holding unit so as to leave an information notification indicating a final state of control by the imaging control unit.
