Inkjet Head Stepped Storage and Inclined Ceiling Vapor Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Inkjet printing systems face issues with vapor confinement in the head unit, leading to abnormal nozzle discharge and increased manufacturing costs due to the need for additional discharge units and valves, which result in non-uniform ink distribution and ink consumption.
Innovation Solution
The inkjet head design features an ink storage unit with a stepped inner storage space and asymmetrically arranged injection holes, along with an inclined ceiling in the head unit's flow space, allowing ink to flow in a predetermined direction and preventing vapor confinement, eliminating the need for additional discharge units and valves.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If an additional discharge unit and valve are installed to remove vapor, then vapor discharge is improved, but device complexity and ink consumption increase
Solution Approach 1:
The harmful vapor is extracted and removed from the head unit through a dedicated discharge hole that communicates with the external atmosphere, separating the vapor removal function from the ink supply path and eliminating the need for complex valve mechanisms
Solution Approach 2:
The ink storage unit automatically discharges vapor through the discharge hole when internal pressure increases due to vapor generation, without requiring external control mechanisms or additional energy input
2Object-affected harmful factors
If a valve and controller are added to discharge vapor, then vapor removal is improved, but manufacturing cost increases
Solution Approach 1:
The discharge hole is implemented as a simple, permanent structural feature of the ink storage unit rather than a costly mechanical valve system, significantly reducing manufacturing costs while maintaining effective vapor discharge functionality
3Object-affected harmful factors
If injection hole is positioned on one side of ink storage unit, then vapor discharge is improved, but ink distribution uniformity deteriorates
Solution Approach 1:
Multiple injection holes are distributed at different positions and orientations within the ink storage unit, with each hole serving a specific directional ink supply function, ensuring uniform ink distribution to all nozzles while maintaining effective vapor discharge

AI summary
An Inkjet head according to an exemplary embodiment of the present invention includes an ink storage unit including an inner storage space, a head unit connected to the ink storage unit, and a plurality of nozzles discharging the ink, wherein the floors of the inner storage space of the ink storage unit form a step. Accordingly, in the Inkjet head of an exemplary embodiment of the present invention, the floors of the inner storage space of the ink storage unit form a step, and the ceiling of the inner flow space of the head unit is inclined, thereby preventing the ink vapor from being confined inside the head unit. Therefore, the ink to be discharged through the nozzle flows in a predetermined direction and does not include ink vapor, thereby preventing discharge deterioration.
