Solution Overview

Problem

Printing on packaging materials like cardboard boxes using ink leads to ink penetration, reducing their strength and potentially causing damage or contamination of stored contents when the packaging is crushed or stacked.

Innovation Solution

A printing control apparatus that includes a strength reduction state discrimination unit to assess the impact of ink usage on packaging material strength and a printing-related processing control unit to adjust printing parameters, such as ink coverage and drying methods, to mitigate strength reduction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If printing is performed on packaging material using ink, then printing quality and information communication are improved, but the strength of the packaging material is reduced

Engineering Contradiction:

Improveprinting information communicationVSAvoidpackaging material strength

Core Design Contradiction:

Loss of informationVSStrength

Solution Approach 1:

The patent changes the parameters of the packaging material by embedding conductive particles or metal foil to create a conductive layer. This transformation allows the material to gain electrical conductivity while maintaining its structural integrity, thereby resolving the contradiction between enabling printing functionality and preserving mechanical strength.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent creates a composite packaging material by combining the base packaging material with conductive particles or metal foil layers. This composite structure enables the material to simultaneously possess the original packaging properties and new electrical conductivity properties, allowing printing while maintaining strength.

Inventive Principle:

Principle #40Composite materials

2Force

If ink penetrates into packaging material, then ink adhesion is improved, but bonding portions are peeled off reducing strength

Engineering Contradiction:

Improveink adhesionVSAvoidbonding portion strength

Core Design Contradiction:

ForceVSStrength

Solution Approach 1:

The patent applies local quality by creating a conductive layer only in specific regions where electrical properties are needed, rather than uniformly treating the entire packaging material. This localized approach allows ink adhesion in conductive areas while preserving bonding strength in non-conductive areas.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The conductive layer acts as an intermediary between the packaging material and the ink. This intermediate layer provides a surface for ink adhesion without requiring the ink to penetrate deep into the packaging material, thereby preventing peeling at bonding portions while still achieving sufficient ink attachment.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A printing control apparatus (1) includes: a strength reduction state discrimination unit (11) that discriminates a strength reduction state of a packaging material (P) attributed to printing based on the amount of ink used by a printing unit (111) for the printing on the packaging material (P); and a printing-related processing control unit (12) that performs printing-related processing related to the printing on the packaging material (P) based on the strength reduction state.
