Automatic Image Painting Device Z-axis Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional automatic painting devices face challenges in maintaining accuracy and consistent coating thickness when painting images with varying widths, particularly those with perspective, leading to quality issues. Additionally, existing methods lack an efficient way for operators to easily generate character data for painting.
Innovation Solution
The automatic image painting device incorporates a paint spray nozzle unit supported by a frame that allows movement along the X-axis, Y-axis, and Z-axis, along with a control unit that adjusts the distance and speed of the nozzle to maintain consistent coating thickness and adapt to width variations. The device also includes a character drawing method that provides a user interface for easily inputting and visualizing character strokes, allowing operators to easily generate character data for painting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If conventional automatic painting devices are used to paint images with varying widths, then the painting process can be automated, but the coating thickness becomes inconsistent and painting accuracy deteriorates
Solution Approach 1:
The patent applies dynamics by making the support frame movable along the Z-axis (vertical direction) to dynamically adjust the height of the paint spray nozzle. This allows the system to adapt to width variations in real-time while maintaining consistent coating thickness through dynamic height adjustment rather than static positioning
Solution Approach 2:
The patent implements feedback by using a sensor to detect the actual width of the image being painted and comparing it with the predetermined width. The control unit then adjusts the support frame height based on this feedback difference, creating a closed-loop control system that maintains coating consistency despite width variations
2Area of stationary object
If conventional automatic painting devices paint images with perspective and varying widths, then painting coverage is achieved, but the device cannot flexibly respond to width changes and maintains poor painting accuracy
Solution Approach 1:
The sensor detects the actual width of the image and provides feedback to the control unit, which compares it with the predetermined width and adjusts the support frame height accordingly. This feedback mechanism enables precise response to width variations while maintaining painting accuracy across different coverage areas
Solution Approach 2:
The system changes the vertical position parameter of the paint spray nozzle by moving the support frame along the Z-axis. This parameter change allows the device to adapt to different image widths and maintain consistent painting quality across varying coverage areas
3Ease of manufacture
If workers manually generate and input character data into the painting device, then character painting is possible, but the process is complex and time-consuming with insufficient ease of operation
Solution Approach 1:
The painting device performs self-service by automatically generating character data directly from uploaded images without requiring manual input from workers. The system processes images autonomously to extract and generate the necessary character data, eliminating the time-consuming manual generation and input process
