Polyhedral Toy Segmentation for Unpredictable Play Patterns
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The playing methods of the Yoshimoto Cube are limited in terms of patterns, and the toy lacks extensibility for varied play content, especially when used individually or in combinations of multiple cube toys.
Innovation Solution
A polyhedral toy composed of eight pieces, each formed by removing three adjacent faces of a cube to create three adjoining quadrangular pyramids, allowing for various coupling configurations and transformations, enabling a wide range of playing patterns and combinations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the toy is designed with fixed cube and stellated polyhedron forms, then the structure is simple and easy to manufacture, but the playing patterns are limited
Solution Approach 1:
The toy is divided into eight independent polyhedral pieces, each with a specific configuration of three adjacent faces. These segments can be independently manipulated, combined, and transformed, enabling multiple playing patterns including forming cubes, stellated polyhedrons, and various intermediate forms that were not possible with fixed structures
Solution Approach 2:
The polyhedral pieces are designed to be movable and transformable rather than fixed. Each piece can rotate, combine with other pieces, and change its spatial configuration, allowing the toy to dynamically transition between different forms and playing patterns, enhancing versatility without permanently increasing structural complexity
2Adaptability or versatility
If the toy requires two main bodies to play, then the transformation functions are achieved, but the extensibility for individual use and combination play is poor
Solution Approach 1:
Each of the eight polyhedral pieces is designed with universal functionality, capable of serving multiple roles: they can be used individually for solo play, combine with other pieces to form various configurations, and work together in pairs or groups. This multi-functionality eliminates the limitation of requiring specific paired main bodies while maintaining transformation capabilities
Solution Approach 2:
By segmenting the toy into eight independent pieces rather than two fixed main bodies, the system gains flexibility. Each segment can function independently or combine with others, enabling individual use, paired play, and group combinations, thereby significantly improving extensibility without adding unnecessary complexity

AI summary
An object is to provide, in place of a cube toy such as Yoshimoto Cube, a wide variety of playing patterns, playing patterns which cannot be predicted in terms of change in forms, a polyhedral toy which can be enjoyed in terms of change in form even when only one polyhedral toy is used, and a polyhedral toy having extensibility for achieving a wide variety of contents of play through combination of two or more polyhedral toys. Therefore, when a polyhedral piece (U1) forming the toy is formed with three quadrangular pyramids (G1 to G3) having, among six triangular faces (T1 to T6) of a cube (R), three faces (R1 to R3) as bottom faces, the polyhedral piece (U1) includes a triangle surface (10) formed of six triangular faces (T1 to T6) other than respective side faces of the quadrangular pyramids (G1 to G3) placed on one another. When polyhedral pieces (U1 to U8) each having the configuration described above form a toy (1) unfolded into a cuboid shape of two rows and four columns as illustrated in FIG. 1, in plan view on a top face of the toy (1), in each of the first row and the second row, the triangle surface (10), the third face (R3), the third face (R3), and the triangle surface (10) are arranged in the stated order.
