Solution Overview

Problem

Existing systems fail to control the adhesion force applied when sealing folded printed matters with pressure adhesive toner effectively, leading to inconsistent sealing quality and potential accidental peeling of adhesive surfaces.

Innovation Solution

A printed-matter sealing processing system that identifies the type of printed matter and adjusts adhesion force by controlling temperature, pressure, and transport speed of rollers based on the type, ensuring stronger sealing for confidential documents.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a fixed adhesion force is applied to all printed matter types, then the sealing process is simple to operate, but the sealing quality becomes inconsistent and confidential documents may peel accidentally

Engineering Contradiction:
Improvesealing quality consistencyVSAvoidsealing process complexity
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The sealing device dynamically adjusts adhesion force parameters (temperature, pressure, transport speed) based on the detected type of printed matter, transitioning from a static fixed-force system to a dynamic adaptive system that optimizes sealing for each document type

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes physical parameters (temperature, pressure, transport speed) of the sealing process based on the printed matter type, allowing different adhesion forces to be applied to confidential versus non-confidential documents

Inventive Principle:
Principle #35Parameter changes

2Strength

If higher adhesion force is applied to all printed matter, then confidential documents are sealed robustly, but non-confidential documents may experience excessive pressure and potential damage

Engineering Contradiction:
Improveadhesion forceVSAvoidexcessive pressure damage
Core Design Contradiction:
StrengthVSObject-affected harmful factors

Solution Approach 1:

The system applies different adhesion force levels to different types of printed matter based on their confidentiality requirements, providing locally optimized sealing strength rather than uniform force across all documents

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system adjusts temperature, pressure, and transport speed parameters based on the detected printed matter type, applying higher adhesion force only when needed for confidential documents while using lower force for non-confidential ones

Inventive Principle:
Principle #35Parameter changes
