Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid discharge apparatuses face challenges in effectively removing foreign substances like dust and fluff during printing, which can lead to reduced printing quality and nozzle clogging.
Innovation Solution
The apparatus incorporates a remover, charger, static eliminator, and cleaner to capture and eliminate static electricity from foreign substances on the medium, ensuring they do not adhere to the nozzle during printing, using a maintenance mechanism that charges the remover before printing and cleans it afterward.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a remover is used to remove foreign substances on the medium, then printing quality is improved, but static electricity causes foreign substances to adhere to the nozzle
Solution Approach 1:
The charger performs preliminary charging of the remover before printing to create electrostatic repulsion that prevents foreign substances from adhering to the nozzle during the printing process
Solution Approach 2:
The system changes the electrostatic parameter of the remover by charging it, transforming its electrical properties to actively repel foreign substances and prevent them from reaching the nozzle
2Reliability
If the remover is charged to prevent foreign substance adhesion, then nozzle protection is improved, but static electricity accumulates on the remover
Solution Approach 1:
The system continuously manages the electrostatic state of the remover through charging before printing and eliminating static electricity after printing, ensuring the remover remains effective without harmful static accumulation
Solution Approach 2:
The static electricity elimination is performed periodically after printing cycles, resetting the electrostatic state of the remover for the next printing operation while preventing harmful static accumulation
3Device complexity
If foreign substances are not removed, then device complexity is reduced, but nozzle clogging occurs reducing productivity
Solution Approach 1:
The remover serves itself by utilizing electrostatic charging to automatically attract and remove foreign substances from the medium, eliminating the need for complex mechanical removal mechanisms while maintaining high printing efficiency
