Liquid Ejecting Apparatus Separate Collection Units
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Liquid ejecting apparatuses face challenges in properly performing flushing when ejecting multiple liquids with different characteristics, as they can chemically react and solidify in the idle discharge receiving unit, potentially damaging the unit.
Innovation Solution
The apparatus includes separate collection units for each type of liquid, with rotating bodies and suction systems designed to collect and manage the liquids effectively, preventing mixing and solidification on the circumferential surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If multiple types of liquids are ejected to a common idle discharge receiving unit, then the structure is simple, but the liquids chemically react and solidify, damaging the unit's function
Solution Approach 1:
The patent divides the idle discharge receiving unit into multiple separate receiving units, with each unit dedicated to collecting a specific type of liquid. This segmentation prevents different liquids from mixing and reacting chemically, thereby maintaining the functional reliability of the system while managing structural complexity through organized separation.
2Reliability
If multiple types of liquids are collected separately in separate collection units, then flushing can be properly performed, but the device complexity increases
Solution Approach 1:
The patent implements separate collection units for different liquid types, ensuring that flushing operations can be performed effectively without chemical reactions between liquids. This segmentation directly improves flushing performance by maintaining liquid purity and preventing solidification, while the increased device complexity is managed through systematic organization of the separate units.

AI summary
A liquid ejecting apparatus includes a liquid ejecting unit that can eject a first liquid and a second liquid to a medium, a first rotating body having a circumferential surface that can receive the first liquid ejected from the liquid ejecting unit, a first sliding contact member that can be slidably in contact with the circumferential surface of the first rotating body, a first collection unit that collects the first liquid that is collected from the circumferential surface by the first sliding contact member, a second rotating body having a circumferential surface that can receive the second liquid ejected from the liquid ejecting unit, a second sliding contact member that can be slidably in contact with the circumferential surface of the second rotating body, and a second collection unit that collects the second liquid that is collected from the circumferential surface by the second sliding contact member.
