Chemical Agent Replenishment in Printing Processes for Defect Prevention

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Printing defects occur due to the undesired depletion of a critical ingredient in the printing process, which affects image quality and is not related to the physical characteristics or age of the treatment formulation, but rather due to contamination, leading to excessive refill requirements and reduced printing quality.

Innovation Solution

A system and method that includes a liquid reservoir with a depletable chemical agent, a replenishment reservoir, and detection means to identify the depletion, allowing for the transfer of additional chemical agent to maintain the required threshold level, thereby preventing or minimizing printing defects.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of stationary object

If the treatment formulation is refilled during the printing process, then the printing process can continue, but the printing quality deteriorates due to contamination and depletion of critical ingredients

Engineering Contradiction:

Improveprinting process continuityVSAvoidprinting quality

Core Design Contradiction:

Duration of action of stationary objectVSManufacturing precision

Solution Approach 1:

The system employs detection means to monitor the amount of depletable ingredient in the treatment formulation and provides feedback to the control unit. When the ingredient amount falls below a threshold, the system automatically initiates replenishment, ensuring printing quality is maintained while allowing continuous operation

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system is designed to automatically detect ingredient depletion and replenish the treatment formulation without requiring manual intervention. The replenishment reservoir and transfer means enable the system to self-correct the depletion issue, maintaining both continuity and quality

Inventive Principle:

Principle #25Self-service

2Manufacturing precision

If excessive refill of treatment formulation is performed, then printing quality can be maintained, but waste and costs increase

Engineering Contradiction:

Improveprinting qualityVSAvoidtreatment formulation waste

Core Design Contradiction:

Manufacturing precisionVSLoss of substance

Solution Approach 1:

The detection means provides precise feedback on the actual amount of depletable ingredient remaining, allowing the system to replenish only when necessary and in the exact amount needed, avoiding both over-refilling and under-refilling

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system monitors and maintains the concentration of the depletable ingredient within an optimal range by making precise adjustments through controlled replenishment, rather than performing excessive refills that would waste material

Inventive Principle:

Principle #35Parameter changes

3Loss of substance

If the amount of depletable ingredient is reduced, then refill requirements decrease, but printing defects increase

Engineering Contradiction:

Improverefill frequencyVSAvoidprinting defect prevention

Core Design Contradiction:

Loss of substanceVSReliability

Solution Approach 1:

The detection means continuously monitors the ingredient amount and triggers replenishment when the threshold is approached, allowing the system to maintain optimal ingredient levels throughout the printing process, preventing defects while managing refill frequency

Inventive Principle:

Principle #23Feedback
