Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional production methods are used with numerous samples and combustion tests, then burnup degree standard compliance is ensured, but production efficiency is reduced and manufacturing time increases

Engineering Contradiction:

Improveburnup degree standard complianceVSAvoidproduction efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent creates a burnup degree conversion table in advance that stores the relationship between image data characteristics and burnup degrees. This preliminary action allows the system to predict burnup degrees directly from image data without performing actual combustion tests during production, thereby ensuring compliance while maintaining high productivity

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent uses image data as a virtual copy or representation of the actual printed layer. By analyzing the image data through the conversion table, the system can predict burnup degree characteristics without creating physical samples for testing, thus eliminating the need for numerous combustion tests while ensuring standard compliance

Inventive Principle:

Principle #26Copying

2Reliability

If numerous physical samples are produced for testing, then burnup degree verification is achieved, but material consumption and production costs increase

Engineering Contradiction:

Improveburnup degree verificationVSAvoidmaterial consumption

Core Design Contradiction:

ReliabilityVSLoss of substance

Solution Approach 1:

The patent replaces physical samples with digital image data copies. The burnup degree conversion table enables verification of burnup degree characteristics by processing image data alone, eliminating the need to produce and test numerous physical samples, thus preventing material consumption while ensuring reliable verification

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The patent substitutes the mechanical/physical combustion testing process with a computational analysis system. By using the burnup degree conversion table to calculate predicted burnup degrees from image data, the system replaces the need for physical combustion tests and sample production, thereby eliminating material consumption associated with sampling

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Adaptability or versatility

If digital printers are used for rapid production with small lots, then production flexibility is improved, but ensuring burnup degree compliance becomes more difficult

Engineering Contradiction:

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent implements a feedback mechanism where the burnup degree conversion table provides predicted burnup degree information based on image data characteristics. This feedback allows the system to automatically verify compliance for each production batch, ensuring that even with high flexibility and small lots, burnup degree standards are consistently met

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The burnup degree conversion table is prepared in advance with the relationship between image data and burnup degrees. This preliminary action enables the system to quickly assess compliance for any digital printing job without requiring time-consuming physical tests, thus maintaining both flexibility and reliability
