Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If measurement processing is performed on multiple color validation servers, then measurement coverage and validation reliability are improved, but switching between servers interrupts measurement processing and requires re-initialization

Engineering Contradiction:

Improvecolor validation reliabilityVSAvoidmeasurement processing continuity

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system performs preliminary actions by storing measurement results in the information processing apparatus before server switching occurs. When a server switch is detected, the apparatus retrieves and restores the previously stored measurement results, allowing the measurement process to continue from where it left off without requiring re-initialization or losing progress.

Inventive Principle:

Principle #10Preliminary action

2Adaptability or versatility

If connection switching among multiple servers is allowed, then system flexibility and adaptability are improved, but measurement processing is interrupted and user convenience is degraded

Engineering Contradiction:

Improveserver connection flexibilityVSAvoidmeasurement processing time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system maintains continuity of useful action by preserving measurement results in the information processing apparatus across server switches. When switching to a different server, the apparatus restores the previously stored measurement results, ensuring that the measurement process continues seamlessly without time loss or interruption, thus maintaining productivity while allowing server flexibility.

Inventive Principle:

Principle #20Continuity of useful action

3Ease of operation

If measurement results are stored locally in the information processing apparatus, then resumption convenience is improved, but data storage requirements and system complexity increase

Engineering Contradiction:

Improvemeasurement resumption convenienceVSAvoidmeasurement control system complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The system extracts and stores only the essential measurement results in the information processing apparatus' memory, separating the critical data from the complex server infrastructure. This selective extraction approach enables easy resumption of measurement processing while minimizing the storage burden and system complexity, as only necessary measurement data is retained rather than entire processing states.

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

In a case where measurement corresponding to a first server among a plurality of servers is performed, a display control unit corresponding to the first server displays the result of the measurement of a measurement device. And in a case where the measurement corresponding to the first server is switched to measurement corresponding to a second server, in a state in which the measurement corresponding to the first server is interrupted, a measurement device control unit stores the result of the measurement of the measurement device performed before the interruption.
