Rotating Printing Head Nozzle Alignment Method
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current printing methods require multiple printing heads of different resolutions to accommodate varying data resolutions, increasing manufacturing costs and processing time, and often result in inefficient use of nozzles leading to increased printing time and memory requirements.
Innovation Solution
A printing method that rotates the printing head to align all nozzles with the data dots, adjusting the resolution of the data to be printed such that the distance between nozzles is a multiple of the dot distances in both directions, allowing for full-hole jet printing without the need for filling blank dots.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple printing heads of different resolutions are prepared to accommodate varying data resolutions, then the printing resolution adaptability is improved, but the manufacturing cost and device complexity increase
Solution Approach 1:
The patent applies dynamics by making the printing head rotatable to change its orientation angle relative to the data pattern. This dynamic adjustment allows a single fixed-resolution printing head to adapt to different data resolutions by rotating to optimal angles, eliminating the need for multiple printing heads of different resolutions and thereby reducing device complexity while maintaining resolution adaptability.
Solution Approach 2:
The patent changes the orientation angle parameter of the printing head to adapt to different data resolutions. By adjusting this geometric parameter (rotation angle), the system can match the printing head's nozzle arrangement with various data patterns, achieving resolution adaptability without adding physical complexity of multiple printing heads.
2Productivity
If the printing head is rotated to align nozzles with data dots, then the nozzle utilization efficiency is improved, but the positioning precision requirements increase
Solution Approach 1:
The patent applies preliminary action by pre-calculating and storing optimal rotation angles for different data resolutions and patterns. Before printing, the system determines the appropriate angle from pre-computed values, allowing the printing head to be positioned correctly without requiring complex real-time precision control during the actual printing process.
Solution Approach 2:
The patent uses partial action by rotating the printing head to specific discrete angles that are sufficient to achieve good alignment, rather than requiring perfect continuous alignment. This approach achieves adequate nozzle utilization without demanding extreme positioning precision, balancing productivity gains with manageable manufacturing requirements.
3Reliability
If blank dots are filled for non-aligned nozzles, then the printing completeness is improved, but the printing time and data processing requirements increase
Solution Approach 1:
The patent applies preliminary anti-action by pre-rotating the printing head to optimal angles that maximize nozzle alignment with data dots. This prevents the problem of misaligned nozzles before printing begins, eliminating the need for time-consuming blank dot filling operations and thereby reducing printing time while maintaining printing completeness.
Data Source
AI summary
A printing method is provided. In the printing method, a printing head is rotated with an angle, such that all the nozzles of the printing head are aligned with the dots of the data to be printed. After being rotated, the printing head performs the printing. If some nozzles of the printing head cannot be aligned with the dots of the data to be printed after the printing head is rotated, the resolution of the data to be printed is increased to solve the misalignment.
