Solution Overview
Problem
Current methods for applying transfer materials to three-dimensional articles, such as inkjet printing and traditional transfer processes, face challenges in achieving high-quality prints on complex surfaces with varying heights or depths, leading to defects in print quality due to limitations in ink jetting distance and suitability for complex shapes.
Innovation Solution
A process involving a transfer component with a composite transfer material that is modified and applied to the article using various methods, including air pressure, vacuum, and conforming mechanisms, to ensure accurate contact and adherence to the article's surface, even on complex geometries.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If inkjet printing is used to print directly on three-dimensional articles, then the printing process can be simplified, but the print quality deteriorates due to limitations in ink jetting distance and accuracy on complex surfaces
Solution Approach 1:
The patent introduces a transfer component as an intermediary between the inkjet printing system and the three-dimensional article. The process prints onto the transfer component first, then transfers the printed image to the article surface. This mediator allows high-quality printing on a flat surface while achieving accurate transfer onto complex three-dimensional geometries, resolving the contradiction between process simplicity and print quality.
2Adaptability or versatility
If traditional transfer processes are used to apply transfer material to articles, then the process can handle complex shapes, but the transfer accuracy deteriorates on surfaces with height or depth differences exceeding limited extents
Solution Approach 1:
The transfer component is designed as a flexible thin film that can conform to complex three-dimensional article surfaces. This flexibility allows the transfer component to adapt to various geometries while maintaining close contact with the article surface, enabling accurate transfer even on surfaces with significant height or depth variations that traditional rigid transfer processes cannot handle.
Solution Approach 2:
The patent uses a copying approach where the printed image is first created on the transfer component, then transferred to the article. This indirect copying method allows the transfer component to bridge the gap between flat printing surfaces and complex three-dimensional article surfaces, achieving high transfer accuracy regardless of the article's geometric complexity.
3Manufacturing precision
If the transfer component is modified to conform to the article surface, then the contact accuracy improves, but the process complexity increases due to additional modification steps
Solution Approach 1:
The transfer component's physical parameters (such as temperature, pressure, or structural properties) are modified to enable it to conform to the article surface. By changing these parameters, the transfer component becomes adaptable to complex geometries, improving contact accuracy without requiring overly complex equipment or processes.
