Solution Overview

Problem

Existing image forming systems face inefficiencies in creating pressure-seal printed matter due to the need for manual material selection and potential errors in pressure sealing, as not all recording materials can be handled by the integrated pressure sealing processing apparatus, leading to issues with bonding force and work efficiency.

Innovation Solution

An integrated image forming system that includes a pressure sealing processing apparatus connected to the image forming apparatus, allowing for seamless conveyance and pressure sealing of recording materials, with a control configuration that determines the appropriate processing parameters based on the material type and grammage, ensuring efficient pseudo-bonding and reducing manual intervention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If the bonding force is increased to prevent unintended peeling, then the bonding strength is improved, but the image may be transferred from one surface to the other surface during peeling

Engineering Contradiction:
Improvebonding forceVSAvoidimage transfer
Core Design Contradiction:
StrengthVSObject-generated harmful factors

Solution Approach 1:

The system automatically adjusts processing parameters (temperature, pressure, time) based on the detected recording material type to achieve optimal bonding force that prevents peeling without causing image transfer. Different material types have different optimal parameter ranges, and the automatic adjustment ensures each material receives appropriate parameters.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If manual setting of recording materials is required for the pressure sealing processing apparatus, then the processing can be customized for each material, but the work efficiency is reduced and the operation becomes troublesome

Engineering Contradiction:
Improvemanual material settingVSAvoidwork efficiency
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The system automatically detects the recording material type and adjusts processing parameters without requiring manual intervention. The pressure sealing processing apparatus self-adapts to different materials through automatic detection and parameter adjustment, eliminating the need for manual setting while maintaining optimal processing conditions.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system automatically changes processing parameters based on detected material properties, enabling seamless adaptation to different recording materials without manual intervention, thereby improving work efficiency while maintaining customized processing for each material type.

Inventive Principle:

3Productivity

If the pressure sealing processing apparatus is connected to the image forming apparatus for continuous processing, then the productivity is improved, but the system may stop due to errors when incompatible recording materials are conveyed

Engineering Contradiction:
Improvecontinuous processing capabilityVSAvoidsystem stability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The system detects and identifies the recording material type before conveying it to the pressure sealing processing apparatus. This preliminary detection allows the system to pre-adjust processing parameters or prevent conveyance of incompatible materials, avoiding errors and system stoppages while maintaining continuous processing capability.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system uses feedback from material detection to automatically adjust processing parameters or control material conveyance. When incompatible materials are detected, the feedback mechanism prevents them from reaching the pressure sealing apparatus, thereby maintaining system reliability while preserving continuous processing productivity.

Inventive Principle:
Principle #23Feedback

4Device complexity

If the processing parameters are fixed for the pressure sealing apparatus, then the device complexity is reduced, but the adaptability to different recording material types is limited

Engineering Contradiction:
Improveprocessing parameter configurationVSAvoidmaterial type adaptability
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The system dynamically adjusts processing parameters based on the detected recording material type. Instead of fixed parameters, the system employs dynamic parameter adjustment that adapts to different materials automatically, maintaining low device complexity while achieving high material type adaptability through automated control.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system automatically changes processing parameters according to the detected recording material type, enabling the pressure sealing apparatus to adapt to various materials without requiring complex manual configuration. This automatic parameter change capability maintains simplicity while achieving versatility.
