A hollow structure Go piece

Abstract

This invention discloses a hollow structure Go piece, belonging to the technical field of chess products. The invention includes a Go piece body, which consists of a shell, a hollow area, and internal supports. The Go piece body adopts a thin-shell structure design, with hollow areas on the shell and internal supports arranged in the non-hollow areas. Specifically, the pentagram series hollow Go pieces use a fully supported structure, while the snowflake series hollow Go pieces feature a combination of columnar and radial support structures. This invention optimizes the layout of the hollow areas and internal supports through topological modeling, significantly reducing weight, achieving a lightweight Go set, and facilitating portability while effectively ensuring the structural strength and durability of the Go pieces. This invention relies on structural optimization to precisely control the center of gravity of the Go pieces, ensuring a high degree of consistency in the center of gravity of each piece through refined structural proportions, effectively improving placement stability and game feel. This invention features a novel structure, diverse shapes, and strong practicality, effectively solving the technical problems of traditional solid Go pieces, such as heavy weight, inconvenience in carrying, difficulty in accurately controlling the center of gravity, and poor consistency.
