Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If measures are actually implemented on the image forming apparatus to diagnose malfunctions, then the influence of the measures can be directly comprehended, but the apparatus operation is disrupted and downtime increases

Engineering Contradiction:
Improvediagnosis accuracyVSAvoidapparatus downtime
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent creates a virtual copy of the image forming apparatus in the form of a simulation model. This virtual model replicates the apparatus's structure and behavior, allowing users to perform diagnostic measurements and test measures on the copy rather than the actual apparatus. The simulation model processes input images and generates predicted output images that mimic the apparatus's response to various measures, enabling accurate diagnosis without physical intervention on the real device.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The system performs preliminary diagnostic actions by simulating various measures on the virtual model before they are implemented on the actual apparatus. Users can evaluate predicted outcomes of different corrective measures in advance, selecting the most appropriate action. This preliminary simulation prevents unnecessary actual interventions and reduces the frequency of apparatus downtime while maintaining diagnostic accuracy.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If measures are implemented on the image forming apparatus, then the malfunction can be corrected, but the cost and disruption increase

Engineering Contradiction:
Improvemalfunction correctionVSAvoidimplementation cost and disruption
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

By using a virtual simulation model as a copy of the actual apparatus, the system allows extensive testing and evaluation of corrective measures without physical implementation costs. Users can simulate component replacements, parameter adjustments, and maintenance actions on the virtual model, assessing their effectiveness before committing to expensive or disruptive actual implementations.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The system enables users to independently perform diagnostic evaluations and measure assessments through the simulation interface without requiring actual apparatus intervention. Users can self-evaluate multiple corrective scenarios and select the most appropriate measure, reducing the need for expensive on-site technician interventions and simplifying the decision-making process.

Inventive Principle:
Principle #25Self-service

3Productivity

If the image forming apparatus is operated continuously, then productivity is maintained, but malfunction diagnosis becomes difficult

Engineering Contradiction:
Improvecontinuous operationVSAvoidmalfunction detection
Core Design Contradiction:
ProductivityVSDifficulty of detecting and measuring

Solution Approach 1:

The simulation model serves as a virtual replica that can be analyzed at any time without affecting actual apparatus operation. Users can input current operational parameters and observed issues into the simulation model to diagnose malfunctions, while the real apparatus continues to produce output. This separation allows continuous monitoring and diagnosis capability without interrupting productivity.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The simulation model acts as an intermediary between the operating apparatus and the diagnostic process. Instead of directly examining the running apparatus (which would require shutdown), users interact with the virtual model that mediates the diagnostic analysis, preserving continuous operation while enabling thorough malfunction detection through simulated testing and comparison.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

An information processing system includes a processor configured to: acquire measure information serving as information regarding a measure that is allowed to be implemented on an image forming apparatus and that is specified by a user, the image forming apparatus forming an image on a recording medium; and generate a predicted image serving as an image predicted to be acquired in response to the image forming apparatus forming an image after the measure decided in accordance with the measure information is implemented.
