Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional building block toys lack secure and versatile connection mechanisms, leading to limited combination diversity and poor mobility, while magnetic blocks pose safety hazards due to exposed magnets that can fall and be ingested by children.
Innovation Solution
A magnetically-connected building block design featuring a hollow cylindrical magnetic body fixing sleeve with C-shaped and inverted-U-shaped grooves for secure magnet placement, using ultrasonic waves for sealing, and automatic-guiding systems to ensure correct polarity alignment, preventing magnet exposure and facilitating easy stacking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If magnetic bodies are directly pushed into or glued into building blocks with exposed surfaces, then magnetic connection is achieved, but magnets are prone to falling and pose safety hazards when ingested by children
Solution Approach 1:
The magnetic bodies are nested within a hollow cylindrical magnetic body fixing sleeve that is fixed in a sleeve pipe on the building block body. The first magnetic body is arranged in an insertion groove and the second magnetic body is arranged in a clamping groove, both grooves being formed in the magnetic body fixing sleeve. This nested structure ensures magnets remain securely enclosed and cannot fall out or be ingested by children.
Solution Approach 2:
The magnetic body fixing sleeve provides a localized enclosed space with specific groove structures (C-shaped insertion groove and inverted-U-shaped clamping groove) that are designed to securely hold magnetic bodies in specific positions. The grooves are sealed at appropriate ends to prevent magnet displacement while maintaining magnetic field functionality.
2Stability of the object's composition
If building blocks are completely fixed after assembly, then structural stability is achieved, but combination diversity and mobility of the assembly are limited
Solution Approach 1:
The magnetic connection mechanism enables dynamic assembly and disassembly of building blocks. The magnetic bodies generate attractive forces that hold blocks together during play, providing stability, but allow blocks to be easily separated when needed, enabling children to create diverse combinations and configurations without permanent fixed connections.
3Strength
If traditional grooves and lugs are used for connection, then structural connection is achieved, but blocks can be connected forcibly in incorrect ways reducing inspiration effect
Solution Approach 1:
The magnetic body fixing sleeve incorporates asymmetric groove structures - a C-shaped insertion groove for the first magnetic body and an inverted-U-shaped clamping groove for the second magnetic body. These asymmetric grooves, combined with the magnetic polarity arrangement, guide children to assemble blocks in the correct orientation through magnetic attraction, preventing forced incorrect connections while maintaining strong magnetic bonding.

Function Achieved in This Case
The solution provides a safer, more versatile, and inspiring building block system that is easy to stack and connect correctly, reducing the risk of magnet exposure and enhancing the play experience for children of all ages, including infants as young as six months.
Implementation Method 1
the polarity direction of the first magnetic body is the same as that of the second magnetic body
Implementation Method 2
sealing between the first magnetic body and the magnetic body fixing sleeve as well as between the second magnetic body and the magnetic body fixing sleeve is achieved through ultrasonic waves
