Description

Technical Field

[0001] This invention belongs to the field of plush toy manufacturing technology, specifically relating to a two-dimensional plate-making method for the torso of a seated plush toy and the plush toy manufacturing process. Background Technology

[0002] In the plush toy industry, traditional pattern making relies entirely on the personal experience and spatial imagination of seasoned professionals. It requires a subjective understanding of the animal's sitting posture, manually disassembling two-dimensional pieces, determining their dimensions, and aligning them for sewing. This method is highly subjective and uncertain, demanding not only extensive experience but also difficulty in standardizing processes. For inexperienced workers, accurately grasping the core structural characteristics of an animal's sitting posture, such as the balance of force on the torso and limbs, the control of the center of gravity, and the curvature of joints, is challenging. This often results in finished products with distorted postures, inaccurate shapes, and loose structures, significantly increasing trial-and-error costs and development cycles.

[0003] Traditional pattern making methods lack scientific data support. Parameters such as cut piece dimensions and curvature are entirely estimated based on experience, making it impossible to accurately replicate the design prototype. Furthermore, the adjustment process relies on repeated sampling and verification, resulting in low efficiency and making it difficult to meet the current market demands for personalized customization and small-batch, rapid production. The industry urgently needs a pattern making method that is independent of experience and based on scientific principles, lowering the barrier to entry and improving pattern making efficiency and accuracy. Summary of the Invention

The panel-making method uses data calculation, which has the following advantages compared to the traditional empirical method: Firstly, by quantifying the structural parameters of the sitting posture and accurately calculating the board opening, the reliance on senior experience is eliminated, enabling inexperienced practitioners to quickly get started in designing animal sitting posture plush toys, significantly lowering the entry threshold and effectively alleviating the shortage of professional talents in the industry.

[0011] Secondly, by relying on scientific data to calculate and cut pieces and determine parameters, the core structures such as the balance of the center of gravity of the sitting posture and the curvature of the limb connection are accurately controlled to achieve high-fidelity replication of the design prototype, avoiding problems such as skewed sitting posture and distorted shape caused by traditional experience methods, and improving the precision of pattern making and the quality of finished products.

[0012] Third, the standardized calculation process shortens the board opening cycle, eliminates the need for repeated prototyping and trial and error, improves development efficiency, reduces costs, adapts to the needs of personalized customization and small-batch quick board production, and provides technical support for industry development.

[0013] In summary, the present invention provides a two-dimensional panel cutting method for the torso of a seated plush toy and a plush toy manufacturing process. This method uses data calculation to replace the traditional experience-based panel cutting method, lowers the entry barrier, significantly improves panel cutting accuracy and development efficiency, and reduces development costs.
