Multi-Nozzle Recording Device Layer Formation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional recording devices require separate processes for recording with inks and reaction solutions, leading to reduced productivity due to the need for additional steps and increased time for bonding and drying.
Innovation Solution
A recording device with a configuration of overlapping and non-overlapping nozzle groups that alternately perform recording with first and second liquids and a reaction solution, allowing simultaneous formation of multiple layers on the medium during scanning and feeding operations, enhancing productivity by integrating the processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If recording with inks and reaction solution is performed separately, then bonding power among color materials is improved, but productivity is reduced due to additional steps and time
Solution Approach 1:
The patent combines the ink recording and reaction solution recording into a single simultaneous operation using multiple nozzle groups. The first nozzle group records inks while the third nozzle group records reaction solution at the same time, merging two separate processes into one unified operation that maintains bonding power while improving productivity
Solution Approach 2:
The patent enables continuous recording operation by having multiple nozzle groups work simultaneously without interruption. The first, second, and third nozzle groups can record inks and reaction solution in an integrated continuous process, eliminating the idle time and sequential waiting that occurs in separate recording operations
2Manufacturing precision
If multiple separate recording passes are performed, then layer formation is achieved, but the number of passes increases reducing efficiency
Solution Approach 1:
The patent transitions from sequential single-pass recording to parallel multi-nozzle recording by adding the dimension of simultaneous operation. Multiple nozzle groups (first, second, and third) operate in parallel to form multiple layers in a single integrated pass, rather than requiring separate sequential passes for each layer
3Manufacturing precision
If inks are recorded first and then reaction solution is recorded separately, then ink spreading is controlled, but processing time is increased
Solution Approach 1:
The patent applies preliminary action by having the reaction solution recorded simultaneously with the inks rather than after. The third nozzle group records the reaction solution at the same time as the first nozzle group records inks, so the reaction solution is already in place to act on the inks as they are being deposited, maintaining spreading control while reducing processing time
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration increases productivity by allowing simultaneous recording and bonding of inks and reaction solutions, reducing the number of passes required and enhancing the adhesion and spreading of inks on the medium, resulting in improved image quality and efficiency.
Implementation Method 1
a third nozzle group in which nozzles configured to perform recording with a reaction solution acting on the first liquid and the second liquid are arranged

AI summary
Provided are a head unit, feeding rollers configured to feed a medium, a carriage configured to cause the head unit to perform scanning, and a control unit configured to control the head unit, the feeding rollers, and the carriage. The control unit performs recording with a first ink and a first reaction solution to form a first layer onto the medium by a first pass operation, performs recording with the first ink to form a second layer on the first layer by a second pass operation, performs recording with a second ink and a second reaction solution to form a third layer on the second layer by a third pass operation, and performs recording with the second ink to form a fourth layer on the third layer by a fourth pass operation.
