Solution Overview
Problem
Existing toy blocks limit creativity and stability in assembled models, leading to frustration and poor intellectual development in children due to restricted shapes and complex assembly processes, with components often failing to snap together effectively.
Innovation Solution
The tetradecahedron toy block features granular unit body components with column heads and slots that allow for simple, stable assembly of various shapes, including asymmetrical and larger upper/lower models, using a locked structure and accessory column heads to enhance connectivity and firmness, while maintaining a low manufacturing cost and easy assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If existing unit body components are used to assemble models, then assembly can be performed with simple components, but the models have poor stability and will collapse upon occurrence of small inclination or shaking
Solution Approach 1:
The unit body is divided into multiple surfaces (first surface, second surface, third surface, fourth surface) with different functions. Each surface can connect with adjacent unit bodies in different directions, providing both simplicity and stability through modular segmentation.
Solution Approach 2:
Each unit body is designed as a universal component that can connect with other unit bodies through multiple surfaces in various directions. The same basic unit body shape serves multiple assembly purposes, eliminating the need for specialized components while maintaining stability through proper geometric arrangement.
2Adaptability or versatility
If components with various shapes are used to increase model diversity, then more kinds of models can be assembled, but the processing costs increase and assembly mode becomes complex and trivial
Solution Approach 1:
While the unit body itself is symmetric, the assembly patterns can be asymmetric. The tetradecahedral shape with 14 faces allows for asymmetric arrangements and configurations, enabling diverse model shapes without requiring asymmetric components. Children can create asymmetric structures by arranging identical units in different patterns.
Solution Approach 2:
The patent transitions from traditional 3D block assembly to 4D assembly by adding the time dimension of dynamic reconfiguration. Unit bodies can be connected and disconnected, allowing models to evolve and transform over time, increasing versatility without increasing component complexity.
3Adaptability or versatility
If special splicing modes are provided among different kinds of components, then some components can be connected, but other components cannot effectively spliced and creativity is limited
Solution Approach 1:
All unit bodies use the same connection interface design with multiple surfaces that can connect to adjacent units. This universal connection method allows any unit body to be spliced with any other unit body in multiple directions, eliminating the need for special splicing modes while maintaining ease of operation.
Solution Approach 2:
The connection system is designed to be dynamic rather than static. Unit bodies can be easily connected and disconnected, and the same connection mechanism works for all components regardless of their position or orientation in the assembly, providing flexibility and ease of operation.
4Ease of manufacture
If only existing unit body components are used for assembly, then manufacturing cost is low, but the creativity of children is limited and intellectual development is hindered
Solution Approach 1:
The tetradecahedral unit body is segmented into 14 faces with different geometric properties (triangular faces, rectangular faces). This segmentation provides multiple connection surfaces that enable diverse spatial arrangements and configurations, stimulating children's creativity and spatial perception while keeping the basic unit shape simple for cost-effective manufacturing.
Solution Approach 2:
The patent enables 4D assembly by allowing dynamic connection and reconfiguration of unit bodies. This adds the dimension of time and transformation, allowing children to create evolving models and explore spatial relationships more deeply, enhancing intellectual development without increasing manufacturing complexity.

AI summary
A device for one or more toy blocks includes a plurality of main unit bodies. The plurality of main unit bodies may have a same structure, shape and volume. Each of the main unit bodies is a tetradecahedron having six square surfaces and eight regular hexagon surfaces. The six square surfaces may be averagely divided into three groups and eight regular hexagon surfaces may be averagely divided into four groups. Two regular hexagon surfaces in a same group are parallel, and more than two main unit bodies are mutually spliced and/or fixedly connected to constitute a group.
