Plotter Ink Level Compensation for Line Thickness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plotters experience variations in line thickness due to changes in ink levels, affecting the consistency of drawn lines as the remaining ink amount influences air pressure and supply to the pen tip.
Innovation Solution
A plotter system with a mounting portion, first and second movement mechanisms, and a processor that acquires plot data and remaining ink information to adjust movement speeds and control mechanisms, ensuring consistent line thickness by compensating for ink level changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the plotter uses a pen with liquid ink, then drawing functionality is achieved, but line thickness varies with ink remaining amount
Solution Approach 1:
The system detects the remaining ink amount in the ink tank and uses this information to dynamically adjust the relative movement speed between the plotter and workpiece. This feedback mechanism allows the plotter to compensate for ink level changes, maintaining consistent line thickness throughout the drawing process.
Solution Approach 2:
The plotter changes the movement speed parameter based on the detected ink remaining amount. When ink level is high, the plotter moves at a reference speed; when ink level decreases, the movement speed is adjusted to compensate for reduced ink supply, thereby maintaining constant line thickness.
2Productivity
If the plotter moves at constant speed, then productivity is maintained, but line thickness varies with ink supply changes
Solution Approach 1:
The plotter transitions from constant speed operation to dynamic speed adjustment. The relative movement speed between the plotter and workpiece is continuously adjusted based on real-time detection of ink remaining amount, allowing the system to adapt to changing ink supply conditions while maintaining line thickness consistency.
Solution Approach 2:
The movement speed parameter is dynamically changed according to ink level detection results. The system establishes a relationship between ink remaining amount and optimal movement speed, adjusting the parameter in real-time to balance productivity and line thickness consistency.
3Manufacturing precision
If the plotter adjusts movement speed based on ink level, then line thickness consistency is improved, but system complexity increases
Solution Approach 1:
The system incorporates an ink level detection mechanism that provides feedback to the control unit. This feedback loop enables automatic adjustment of movement speed without requiring complex manual intervention, achieving line thickness consistency through a relatively simple feedback-based control system.
Solution Approach 2:
The plotter system performs self-adjustment of movement speed based on its own ink level status. The control unit automatically modifies operating parameters according to detected ink remaining amount, eliminating the need for external monitoring or manual adjustment, thereby reducing overall system complexity.

Function Achieved in This Case
The system effectively reduces the impact of ink level variations on line thickness, maintaining consistent drawing quality by dynamically adjusting movement speeds based on ink remaining amounts.
Implementation Method 1
in accordance with a change in a remaining amount of ink contained in an ink tank, an air pressure in the tank changes and a supply amount of the ink to a pen tip changes

AI summary
A plotter includes a mounting portion, a first movement mechanism, a second movement mechanism, a processor, and a memory. The mounting portion is configured to mount with a pen containing a liquid. The first movement mechanism is configured to relatively move the mounting portion and a workpiece in a movement direction. The second movement mechanism configured to relatively move the mounting portion and the workpiece in a direction intersecting the movement direction. The memory is configured to store computer-readable instructions that, when executed by the processor, instruct the processor to perform processes. The processes include acquiring plot data, acquiring information relating to a remaining amount of the liquid of the pen, setting a relative movement speed of the mounting portion and the workpiece, and controlling the first movement mechanism and the second movement mechanism at the set movement speed, and performing drawing on the workpiece.
