Solution Overview

Problem

Existing image diagnosis systems do not notify users of the number of diagnosis charts to be printed, leading to potential interruptions due to the depletion of sheets during the printing process.

Innovation Solution

An image diagnosis system that includes a mechanism to notify users of the number of diagnosis charts required before printing, allowing for informed decision-making and preventing interruptions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the image diagnosis system prints diagnosis charts without notifying the user of the number of charts to be printed, then the printing process can start immediately, but the printing may be interrupted due to running out of sheets

Engineering Contradiction:
Improveprinting speedVSAvoidprinting continuity
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The system performs preliminary calculation of the required number of diagnosis charts based on selected diagnosis items and patterns before starting printing. This advance preparation allows the system to notify users of the sheet consumption in advance, enabling them to prepare appropriate materials and avoid interruptions during the printing process.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If the system notifies the user of the number of diagnosis charts to be printed, then printing interruptions can be prevented, but the printing process requires additional time for notification

Engineering Contradiction:
Improveprinting continuityVSAvoidnotification time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The notification of sheet consumption is provided in advance during the setup phase, before the user initiates the printing process. This preliminary information delivery allows users to make informed decisions about material preparation without causing delays during the actual printing execution.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system provides feedback to the user regarding the number of sheets that will be consumed based on the selected diagnosis items and patterns. This feedback mechanism enables users to adjust their material preparation accordingly, ensuring continuous printing operation without unexpected interruptions.

Inventive Principle:
Principle #23Feedback

3Loss of substance

If the system calculates and notifies the number of diagnosis charts based on diagnosis items and patterns, then sheet consumption can be optimized, but the system complexity increases

Engineering Contradiction:
Improvesheet consumptionVSAvoidsystem complexity
Core Design Contradiction:
Loss of substanceVSDevice complexity

Solution Approach 1:

The system automatically calculates the required number of diagnosis charts by analyzing the selected diagnosis items and patterns without requiring manual intervention. This self-service approach optimizes sheet consumption while maintaining simple user interaction, as the calculation logic is embedded within the system's existing diagnostic framework.

Inventive Principle:
Principle #25Self-service
