Description

Technical Field

[0001] This invention relates to model building in intellectual development, and particularly to a built-in high-strength model building component system and building method, belonging to the field of educational toys for intellectual development. Background Technology

[0002] Over the past decade, the applicant has independently developed a variety of model-building components. Using these components for model building and intellectual development can expand spatial imagination and geometric thinking. Their three-dimensional structure facilitates understanding of symmetry, proportion, angles, center of gravity, and forces. Long-term training can significantly improve spatial intelligence and aid in mathematical geometry, physics, and engineering thinking. The step-by-step assembly process forces participants to reason, correct errors, and review complex structures such as brackets, pavilions, and bridges, requiring layered logical deduction, thus training logical thinking skills. Inserting, connecting, assembling, locking, and adjusting angles improves hand-eye coordination and finger dexterity, indirectly benefiting sensory integration development and writing stability in younger children. These components support free combination, structural modification, and creative additions, allowing children to design their own bridges, houses, towers, and creative installations, fostering divergent thinking, engineering design awareness, and maker thinking. The building process provides an intuitive understanding of physical concepts such as balance, support, levers, and trusses, more intuitive and profound than classroom explanations. The model-building components utilize mortise and tenon joints. Modern connectors combine traditional culture with scientific structure, are disassembled and reassembled, and have a clear gradient from simple to complex, gradually developing the brain. They can also be used to participate in competitions, further stimulating thinking and expression abilities.The related components, building systems, and methods developed by the applicant have already begun large-scale application practices in many places, with a considerable number of participants. During the participants' creative model building and expansion process, many issues that were not addressed in the early stages of component and model design were discovered. Some of these issues are as follows: First, the nodes at the building, extension, and corners of the model generally use various building components with connecting structures. These building components are usually exposed on the surface after the model is built, especially at corners. This has a negative impact on the visual three-dimensionality and integrity of the final model. In the assembly practice, some participants tried to overcome this defect by gluing paper, wood chips, etc. to overcome the "point" structure formed by these components and create a better model effect. However, gluing leads to the problem of non-reusability of components, and the adhesives used are not popular among children. Secondly, there's the issue of stress on components at corners. Components at corners are subjected to forces in at least two directions, and often more than three. During model building, due to factors such as manufacturing precision, fit precision, and thermal expansion and contraction, these corner components experience torsional and shear forces. This stress is more pronounced when there are long extensions connecting the components. When these forces are large, they can damage the components, causing deformation or even breakage. Similarly, the above reasons also lead to poor resistance to external forces and low strength in the assembled model. Thirdly, considering the stability of the assembled model, the fit between components and between components and extensions is generally quite tight. This makes it difficult for teenagers to assemble and connect components, and the same problem exists during disassembly. Fourthly, many model building projects use mortise and tenon joints. In regions with large temperature differences, mismatches caused by temperature changes can make model building more difficult. Summary of the Invention

During the building process, the dovetail tenon of the node component is inserted into the dovetail groove on the extension component to extend the model building.

[0049] The two dovetail tenons of node element A are inserted into the dovetail slots of the two extension elements to extend the model in two orthogonal directions. For example...

Compared with node element A, node element D is designed with a beveled tenon, which can be easily inserted into the dovetail groove. Especially when inserting in the horizontal direction, the node element is often held and inserted into the dovetail groove of the extension element. However, the node element is small and it is difficult to apply force. When inserting in the vertical direction, the extension element is often held and the dovetail groove is inserted into the dovetail tenon. The extension element can easily apply force in the vertical direction.
