Solution Overview
Problem
Existing toy blocks face limitations in assembly due to shape constraints and inconsistent magnetic coupling, particularly with spherical blocks and magnetic toy blocks that incorrectly couple or fail to couple when poles are the same or misaligned.
Innovation Solution
A toy block design featuring a main body with accommodation spaces for plate-shaped magnetic bodies having different polarities, guided by arch-shaped main guides and perpendicular sub guides to ensure stable rotation and correct polarity alignment for strong magnetic coupling, allowing for versatile assembly with various shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If magnetic bodies are disposed at the outsides or insides of blocks for bonding, then toy blocks can be coupled magnetically, but they fail to couple when poles are the same or couple incorrectly when magnetic body locations are dislocated
Solution Approach 1:
The patent applies preliminary action by pre-positioning guide protrusions and guide grooves on the magnetic bodies before assembly. These guide features are预先 configured to automatically align the magnetic bodies during the assembly process, ensuring that opposite polarity surfaces face each other correctly before magnetic coupling occurs. This prevents incorrect coupling when poles are the same and ensures reliable assembly even when blocks are handled freely.
2Adaptability or versatility
If protrusions and coupling grooves are used for engagement, then toy blocks can be coupled mechanically, but the block shape is limited and spherical blocks cannot be used
Solution Approach 1:
The patent replaces the traditional mechanical protrusion-groove engagement system with a magnetic coupling system. Instead of using mechanical interlocking features that require specific geometric shapes, the invention uses magnetic attraction forces that can act through any shape. The magnetic bodies are embedded within or on the surface of blocks of various shapes (including spherical blocks), allowing universal magnetic coupling without requiring shape-specific engagement features.
3Force
If magnetic bodies are used for coupling, then assembly is simplified, but the coupling strength is insufficient when poles are misaligned or the same
Solution Approach 1:
The patent introduces guide protrusions and guide grooves as intermediary mechanical features that mediate between the magnetic bodies and the assembly process. These guide features physically constrain the relative positioning of magnetic bodies, ensuring that opposite polarity surfaces are properly aligned before magnetic attraction takes full effect. This intermediary mechanism prevents same-pole coupling and ensures consistent, strong magnetic coupling by maintaining correct orientation throughout the assembly process.
