Inkjet Print Apparatus Multi-Chamber Head Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing inkjet print apparatuses face increased total process time due to the inefficiencies in replacing heads during the ink ejection process, particularly due to the need for checking and replacing nozzle clogging, which involves multiple steps and atmospheric changes, leading to prolonged operation times.
Innovation Solution
The apparatus includes a configuration with multiple chambers to facilitate efficient head replacement and testing, where a third chamber is used for pre-testing the replacement head module, allowing it to be verified for ink ejection conditions before being introduced into the main chamber, thereby reducing the overall process time and minimizing contamination and atmospheric changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the head is replaced with a replacement head in the internal space of the chamber, then the ink ejection process can continue, but the total process time increases due to atmosphere switching, moving processes, ink charging, and checking procedures
Solution Approach 1:
The patent applies preliminary action by performing the checking process for the replacement head in advance, before it is installed in the first chamber. The replacement head is checked in the third chamber to verify ink ejection conditions, and only after successful verification is it transferred to the first chamber. This eliminates the need to perform checking procedures after head replacement, significantly reducing the total process time while maintaining reliability.
2Productivity
If multiple chambers are used for head replacement and testing, then the head replacement process is streamlined and contamination is minimized, but the device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the inkjet print apparatus into multiple functionally independent chambers: a first chamber for ink ejection, a second chamber for head storage, and a third chamber for replacement head checking. Each chamber performs a specific function, allowing head replacement and testing to occur independently without disrupting the main ink ejection process. This modular segmentation improves productivity by enabling parallel operations while keeping each chamber's design relatively simple.
Solution Approach 2:
The patent uses the second chamber as an intermediary space between the first chamber (ink ejection) and the third chamber (head checking). The replacement head is first verified in the third chamber, then transferred through the second chamber before being installed in the first chamber. This intermediary chamber acts as a buffer that facilitates smooth transitions and minimizes contamination risks without requiring direct interaction between the checking and ejection chambers.

AI summary
Provided are an inkjet print apparatus and an inkjet print method to reduce a process time required for replacing a head module. The inkjet print apparatus includes a first chamber having a head module; a second chamber disposed to contact the first chamber; and a third chamber disposed outside the first chamber and the second chamber and providing a space for performing a test for checking a state of a replacement head module. The method includes placing a first substrate in a first chamber below a head module; vertically moving the head module into the second chamber from the internal space of the first chamber when the head module is replaced with a replacement head module; and performing a test for checking a state of the replacement head module in a third chamber disposed outside the first chamber and the second chamber.
