Laser Cutting Doll Garments via Sublimation Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing doll garment manufacturing methods are complex and time-consuming, particularly in cutting and sewing the front and back pieces, which can result in a less appealing final product if not executed correctly.
Innovation Solution
A method involving printing annular sector-shaped designs on a transfer sheet, sublimation-transferring these designs onto a polyester cloth, and then using laser cutting to create a garment piece that includes both transferred and untransferred regions, thereby simplifying the cutting and sewing processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the manufacturing process includes cutting front and back pieces separately and sewing them together, then the garment structure can be assembled properly, but the manufacturing process becomes complicated and time-consuming
Solution Approach 1:
The patent merges the front piece and back piece into a single integrated pattern design. The transfer sheet contains both front and back garment pieces printed on the same sheet, allowing both pieces to be cut simultaneously from one transferred cloth in one laser cutting operation, eliminating the need for separate cutting and sewing operations
Solution Approach 2:
The patent performs preliminary printing of both front and back piece patterns on the transfer sheet before cutting. The designs are printed at predetermined intervals and positions, and the garment cutting regions are predetermined, allowing the cutting process to directly produce ready-to-assemble pieces without requiring subsequent sewing operations
2Productivity
If multiple designs are printed on the transfer sheet, then production efficiency increases, but the arrangement and cutting precision requirements increase
Solution Approach 1:
The patent segments the transfer sheet into multiple independent design regions, each containing complete front and back piece patterns. Each design is printed at predetermined intervals and can be independently cut out. The segmentation includes dividing the garment into front and back pieces with predetermined cutting lines, allowing precise laser cutting of multiple garments simultaneously while maintaining high production efficiency
Solution Approach 2:
The patent replaces manual measurement and marking with automated laser cutting guided by printed pattern coordinates. The laser cutting apparatus automatically follows the printed design lines on the transfer sheet, eliminating manual positioning errors and ensuring high cutting precision even when multiple designs are arranged on the same sheet

Function Achieved in This Case
This method allows for the efficient production of doll garments with a good appearance while significantly simplifying the manufacturing process, reducing the complexity of cutting and sewing, and ensuring consistent quality.
Implementation Method 1
sublimation-transferring the plurality of designs to a transfer target cloth using the printed transfer sheet
Implementation Method 2
cutting the transferred cloth by performing laser cutting along an edge of a garment cutting region

AI summary
A doll garment manufacturing method includes: printing designs at intervals on a transfer sheet to prepare a printed transfer sheet, each of the designs having an annular sector shape; sublimation-transferring the designs to a transfer target cloth using the printed transfer sheet to prepare a transferred cloth including transferred regions in which the designs are transferred, respectively, and an untransferred region in which the designs are not transferred; and cutting the transferred cloth by performing laser cutting along an edge of a garment cutting region of the transferred cloth to take out a cut piece corresponding to the garment cutting region from the transferred cloth, the garment cutting region including one of the transferred regions and part of the untransferred region. A doll garment is prepared from the cut piece taken out from the transferred cloth.
