Solution Overview
Problem
Conventional dyeing base bodies face challenges in enhancing the quality and efficiency of vapor deposition transfer dyeing, particularly with non-uniform dyeing and reduced heating efficiency when using paper, glass, or metal materials.
Innovation Solution
A dyeing base body with a metal sheet base and an electromagnetic wave absorption layer on the opposite side to the dye attachment, which absorbs heat from electromagnetic waves and transfers it to the sublimable dye for uniform deposition on a resin body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If paper is used as the dyeing base body, then heating efficiency is improved, but dye uniformity deteriorates due to strike-through
Solution Approach 1:
The base body is segmented into multiple layers: a paper base layer for heating efficiency and a metal foil layer for dye containment. This segmentation allows each layer to fulfill its specific function - the paper provides rapid heat transfer while the metal foil prevents dye strike-through, resolving the contradiction between heating efficiency and dye uniformity
Solution Approach 2:
The invention uses a composite structure combining paper and metal foil materials. The paper base body maintains high heating efficiency while the metal foil coating provides dye barrier properties. This composite material approach enables simultaneous achievement of rapid heating and uniform dye distribution without strike-through
2Manufacturing precision
If glass or metal material is used as the dyeing base body, then dye uniformity is improved, but heating efficiency deteriorates
Solution Approach 1:
The base body is divided into functional segments: a paper layer responsible for rapid heating and a metal foil layer responsible for dye containment and uniform distribution. This segmentation allows the system to achieve both high heating efficiency from the paper and excellent dye uniformity from the metal foil, overcoming the limitations of using单一 materials
Solution Approach 2:
By combining paper and metal foil into a composite base body structure, the invention achieves synergistic effects where the paper provides thermal conductivity for efficient heating and the metal foil provides dye barrier and uniform distribution properties, thus improving both heating efficiency and dye uniformity simultaneously
3Manufacturing precision
If a metal base is used, then dye strike-through is prevented, but electromagnetic wave absorption is insufficient
Solution Approach 1:
The invention uses a composite structure of paper and metal foil where the paper base body provides excellent electromagnetic wave absorption for efficient heating, while the metal foil layer provides dye containment. This composite approach resolves the contradiction by assigning different functions to different materials - the paper absorbs electromagnetic waves effectively while the metal foil prevents dye strike-through
