Solution Overview
Problem
Existing printing technologies face limitations in effectively utilizing ink phase change for enhanced printing capabilities, particularly in achieving deep penetration into materials and color variability.
Innovation Solution
A printing apparatus and method involving an ink treatment chamber with heating elements and a nozzle for ejecting ink in a gaseous state, allowing for sublimation or evaporation of ink from a non-gaseous state, enabling ink to penetrate materials and facilitating color variation through separate ink apparatuses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If liquid ink is applied directly to material, then the printing process is simple, but the ink only remains on the surface and cannot penetrate deeply into the material
Solution Approach 1:
The patent changes the physical state parameter of ink from liquid to gaseous phase through heating in an ink treatment chamber. This parameter change enables the ink to penetrate deeply into the material as gas, then embed within the material structure, solving the contradiction between operational simplicity and penetration depth.
Solution Approach 2:
The patent utilizes phase transition of ink from non-gaseous state to gaseous state through heating elements. The ink undergoes evaporation or sublimation to become gas, which then penetrates the material and condenses back, achieving deep penetration while maintaining a relatively simple printing apparatus structure.
2Adaptability or versatility
If solid-form pigments are used in sublimation ink, then color variability is improved, but the complexity of the printing system increases due to multiple components
Solution Approach 1:
The patent segments the printing system into separate printing apparatuses for different colors (first printing apparatus with first color ink, second printing apparatus with second color ink). Each apparatus handles one color type, simplifying the control of each individual unit while achieving overall color variability through the combination of multiple segmented units.
Solution Approach 2:
The patent creates a universal ink treatment chamber design that can handle different types of ink (liquid or solid-form pigments in liquid carrier) through the same heating and phase change mechanism. This multi-functional design allows the system to process various ink types without requiring fundamentally different apparatus structures, thus managing complexity while maintaining versatility.

AI summary
A printing apparatus includes an ink treatment chamber having an inlet for receiving ink into the chamber. The ink is received in a non-gaseous statement. Heating elements heat the ink in the ink treatment chamber. After being heated, a nozzle ejects the heated ink. The heating of the ink may cause the ink to be changed to a gaseous ink and the gaseous ink may be ejected by the nozzle.
