Problem

Existing building blocks are limited by fixed cuboid shapes, lack of diversity, safety concerns due to sharp edges, instability when stacked, and lack of decorative appeal, leading to decreased child interest and potential injury.

Innovation Solution

A magnetic building block design featuring a square front and back side with notches, protruding chucks, small magnets, embedded paper, reinforcing ribs, and a silicone protective ring, enhancing stability, safety, and ease of use while allowing for diverse configurations and decorative patterns.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If building blocks are made with fixed cuboid shapes, then manufacturing is simple, but shape diversity is limited and child interest decreases

Engineering Contradiction:

Improvemanufacturing simplicityVSAvoidshape diversity

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The building block is divided into a front side component and a back side component that can be separately manufactured and then assembled together. The front side includes decorative patterns while the back side includes magnetic elements, allowing each part to be optimized independently for both manufacturing ease and functional diversity

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The building block design incorporates multiple functions into a single toy: decorative appeal through patterns, magnetic connection capability, structural stability through notches and chucks, and safety through rounded edges. This multi-functionality increases child interest while maintaining manufacturing efficiency

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Strength

If building blocks are made with sharp edges and corners, then structural integrity is strong, but safety threats to children increase

Engineering Contradiction:

Improvestructural integrityVSAvoidsafety threats

Core Design Contradiction:

StrengthVSObject-affected harmful factors

Solution Approach 1:

The building block features rounded edges and corners instead of sharp angles. The front side and back side components both have rounded contours that eliminate safety threats to children while maintaining the structural integrity needed for stable stacking and construction

Inventive Principle:

Principle #14Spheroidality (Curvature)

3Ease of operation

If building blocks are stacked without magnetic elements, then assembly is simple, but stability is poor and blocks easily fall down

Engineering Contradiction:

Improveassembly simplicityVSAvoidstacking stability

Core Design Contradiction:

Ease of operationVSStability of the object's composition

Solution Approach 1:

The patent replaces purely mechanical stacking (relying on friction and gravity) with a magnetic connection system. Small magnets embedded in the back side of each block provide stable attraction forces that hold blocks together securely, preventing them from easily falling down while maintaining ease of assembly through simple attachment and detachment

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

4Strength

If building blocks are made as single integrated pieces, then structural strength is high, but repairability is difficult when damaged

Engineering Contradiction:

Improvestructural strengthVSAvoidrepairability

Core Design Contradiction:

StrengthVSEase of repair

Solution Approach 1:

The building block is segmented into a front side component and a back side component connected through notches and protruding chucks. This modular design allows the front side with decorative patterns to be separated from the back side with magnetic elements, enabling easy replacement of damaged parts while maintaining overall structural strength through the connection mechanisms

Inventive Principle:

Principle #1Segmentation

AI summary

The present utility model provides a magnetic building block. A building block back side is installed on a rear end of a building block front side. Four notches are formed on both of the rear end of the building block front side and a front end of the building block back side. Four protruding chucks are formed on both of the rear end of the building block front side rear end and the front end of the building block back side. Four small magnets are disposed on the front end of the building block back side. The protruding chuck and the notch are disposed on two sides of the small magnet. An embedded paper is disposed between the building block front side and the building block back side. The embedded paper is inlaid in a rectangle surrounded by the notch, the small magnet, and the protruding chuck.
