Solution Overview

Problem

Conventional image forming systems require users to manually check and correct the setting mode of recording materials to ensure that secret information is printed on the correct surface with a pressure-bonding paste, leading to increased preparation time and effort.

Innovation Solution

An image forming system with an inputting portion to specify the front and back surfaces of recording materials, a displaying portion to confirm the correct orientation, and a pressure-bonding apparatus to fold and bond the materials under controlled heat and pressure, ensuring accurate placement of images on the appropriate surfaces.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the user manually checks the setting mode by performing test printing, then the correctness of recording material orientation can be confirmed, but the preparation time becomes excessive and the operation becomes troublesome

Engineering Contradiction:

Improvecorrectness of recording material orientationVSAvoidpreparation time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent displays a virtual copy or simulation of the pressure-bonding printed matter on a display device, showing how the image will be formed on the recording material based on the current setting mode. This allows users to verify the correctness of the orientation without performing actual test printing, thereby confirming reliability while eliminating time loss

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The system automatically determines the correct setting mode by detecting the type of recording material loaded and configures the image formation accordingly. The system serves itself by autonomously identifying material orientation and adjusting parameters, eliminating the need for manual test printing while ensuring correct orientation

Inventive Principle:

Principle #25Self-service

2Productivity

If the user sets the recording material in an erroneous set mode, then the image can be formed quickly, but the secret information image is formed on the wrong surface resulting in defective pressure-bonding printed matter

Engineering Contradiction:

Improveimage formation speedVSAvoidaccuracy of image placement on correct surface

Core Design Contradiction:

ProductivityVSManufacturing precision

Solution Approach 1:

The system provides visual feedback by displaying the predicted result of image formation on the recording material based on the current setting mode. This feedback loop allows users to verify before production, ensuring manufacturing precision is maintained without sacrificing productivity

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system performs preliminary verification by displaying a simulation or virtual representation of the image formation result before actual printing occurs. This preliminary action prevents defective output by allowing users to correct setting mode errors before committing resources to actual image formation

Inventive Principle:

Principle #10Preliminary action

3Ease of operation

If the system automatically determines the setting mode based on recording material type, then the operation becomes simpler and faster, but the system complexity increases due to additional detection and control functions

Engineering Contradiction:

Improvesimplicity of setting processVSAvoidcomplexity of detection and control system

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The image forming apparatus automatically detects the recording material type and determines the appropriate setting mode without user intervention. The system serves itself by autonomously configuring parameters based on material characteristics, greatly simplifying operation while the added complexity is contained within the automated detection and control subsystems

Inventive Principle:

Principle #25Self-service
