Solution Overview

Problem

Existing magnetic suction building blocks have limited stacking angles and connecting modes, leading to a lack of variety in building designs and reduced interest in modeling among children.

Innovation Solution

A magnetic building block design featuring a first and second compartment part with rotating magnets and a stop assembly, allowing for misplaced connections and various stacking angles through crossed corners, enhanced by a partition plate and reinforcing ribs for stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If magnetic suction building blocks are designed with single stacking angles and same-axis connection, then the structure is simple and easy to manufacture, but the connecting modes are limited and playing methods are simple

Engineering Contradiction:
Improveconnecting modesVSAvoidstructure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The building block is divided into multiple compartments (first compartment part and second compartment part) separated by a partition plate, with each compartment containing independent magnets. This segmentation allows different compartments to provide different stacking angles and connecting modes, resolving the contradiction between versatility and complexity by organizing multiple functions into distinct segments.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces crossed corners (first crossed corner and second crossed corner) that extend beyond the traditional single-axis stacking, adding spatial dimensions to the connection possibilities. This dimensional expansion enables misplaced modeling and diverse stacking angles without fundamentally complicating the basic block structure.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If magnetic suction building blocks are designed with single stacking angles, then the manufacturing precision requirement is low, but the building designs lack variety

Engineering Contradiction:
Improvebuilding designsVSAvoidstacking angle precision
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

Different compartments are designed with specific local qualities - the first compartment part contains a first magnet part for one type of connection, while the second compartment part contains a second magnet part for another type of connection. This local differentiation allows each part to excel at its specific function without requiring high precision across all connections simultaneously.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The magnets are designed to be rotatable within their respective compartments, introducing dynamic adjustment capability. This allows the magnetic connection orientation to adapt during play rather than requiring precise pre-set stacking angles, resolving the contradiction between design variety and manufacturing precision.

Inventive Principle:
Principle #15Dynamics

AI summary

The present disclosure provides a magnetic building block. Furthermore, the stop assembly is separated into the upper stop part and the lower stop part by the partition plate part, so that the strength of the stop assembly can be improved. The upper stop part may stop the first magnet part at the first compartment part, and the lower stop part may stop the second magnet part at the second compartment part.
