Liquid Discharging Head Pattern Recording on Single Medium
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid discharging apparatuses require multiple recordable sheets to record different patterns, such as conveying-amount adjuster and discharging-timing adjuster patterns, due to distinct conveying actions and amounts, which increases material usage and complexity.
Innovation Solution
A liquid discharging apparatus with a liquid discharging head, a relatively-movable device, and a controller that allows for the recording of relative movement adjuster patterns and different patterns side by side on the same medium by controlling the discharging head and moving device to adjust relative movement amounts, enabling efficient recording on a single medium.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If different patterns (conveying-amount adjuster and discharging-timing adjuster) are recorded on different recordable sheets, then each pattern can be recorded with its specific conveying action and amount, but the number of recordable sheets increases and material usage increases
Solution Approach 1:
The patent combines multiple different patterns (conveying-amount adjuster pattern and discharging-timing adjuster pattern) onto a single recordable sheet. The controller coordinates the liquid discharging head and relatively-movable device to record these patterns side by side in different regions of the same sheet, eliminating the need for multiple separate sheets while maintaining the specific conveying requirements for each pattern type.
Solution Approach 2:
The recordable sheet serves multiple functions by recording different types of adjuster patterns on the same medium. The system enables one sheet to fulfill multiple calibration purposes (conveying amount adjustment and discharging timing adjustment), making the recording process more efficient and reducing material consumption.
2Manufacturing precision
If conveying actions are performed at different timings with different conveying amounts for different patterns, then each pattern can be optimized, but the recording process complexity increases
Solution Approach 1:
The recordable sheet is divided into different regions, with each region designated for a specific type of pattern (e.g., conveying-amount adjuster pattern in one region, discharging-timing adjuster pattern in another region). The controller manages separate conveying actions for each region at different timings with different conveying amounts, allowing optimized recording for each pattern type while organizing the complex process through spatial segmentation.
Solution Approach 2:
The system employs dynamic control where the conveying amount and timing are adjusted according to the specific region and pattern type being recorded. The relatively-movable device and liquid discharging head coordinate their movements dynamically, changing conveying parameters on-the-fly based on which pattern is being recorded, enabling precise positioning accuracy despite the varying requirements.

AI summary
A liquid discharging apparatus, having a liquid discharging head, a relatively-movable device, and a controller, is provided. The controller controls the liquid discharging head and the relatively-movable device to record a plurality of relative movement adjuster patterns, arranged at different positions in an arrayed direction, and a different pattern, arranged side by side with the plurality of relative movement adjuster patterns along a direction orthogonal to an arrayed direction on a same liquid-discharge objective medium. The controller controls the relatively-movable device, after recording at least one of the plurality of relative movement adjuster patterns, and before recording a next one of the plurality of relative movement adjuster patterns next to the at least one of the plurality of relative movement adjuster patterns, to perform a relative moving action by a moving amount different from a predetermined relative moving amount for recording the different pattern at least once.
