Solution Overview
Problem
Conventional methods for painting or imaging on structure surfaces, especially outer walls, are hazardous, labor-intensive, and limited in expressing large images due to manual labor and restricted printing ranges of automatic printing apparatuses.
Innovation Solution
An image processing method that divides the target surface into regions to optimize the printing range of an automatic printing apparatus, allowing for efficient and accurate printing by setting print starting positions based on boundary lines and movement ranges of the nozzle, enabling larger image printing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual painting or imaging is performed by workers on structure surfaces, then naturalness and quality of the task are improved, but labor costs increase and workers are exposed to safety hazards
Solution Approach 1:
The patent replaces manual mechanical painting operations with an automated printing apparatus that uses a nozzle to eject ink or paint material. The controller automatically controls the nozzle movement and printing process, eliminating the need for workers to manually paint while maintaining or improving quality consistency.
Solution Approach 2:
The printing apparatus is designed to autonomously perform the painting task without human intervention during the actual printing process. The controller manages the entire operation including nozzle positioning, movement speed control, and printing parameters, making the system self-sufficient for the painting task.
2Manufacturing precision
If manual painting or imaging is performed by workers on structure surfaces, then quality of the task is improved, but labor costs and task performing time increase
Solution Approach 1:
The patent replaces manual painting operations with an automated printing apparatus controlled by a controller. The system automatically manages nozzle movement, printing speed, and material ejection, significantly improving task performing efficiency while maintaining quality consistency throughout the painting process.
Solution Approach 2:
The printing apparatus incorporates dynamic control capabilities where the controller can adjust movement speed, ejection timing, and printing parameters in real-time based on the task requirements. This dynamic adjustment optimizes both quality and efficiency during the painting process.
3Extent of automation
If conventional automatic printing apparatus is used for printing large images on structure surfaces, then automation is achieved, but printing range is limited
Solution Approach 1:
The patent divides the large target surface into multiple printable regions or sections. The controller manages the printing process by sequentially printing each section, effectively extending the overall printing range beyond the limitations of a single printing operation while maintaining automated control throughout.
Solution Approach 2:
The patent extends the printing capability from a single fixed position to multiple positions by implementing movement control in multiple directions. The nozzle can move across the target surface in a systematic pattern, effectively expanding the printing range from a limited area to a large-scale surface through multi-dimensional movement.
