Solution Overview

Problem

Building block toys made of plastic materials have weak structural strength, prone to deformation and damage, leading to poor durability and short service life due to the use of magnets for stacking, which are not effectively integrated with the main housing.

Innovation Solution

A magnetic building block design featuring a main housing with a cylinder and partition plate reinforced by a stiffener structure, magnet housings with connecting cylinders, and cover bodies with stiffener structures, forming an integral structure with enhanced structural strength and stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If magnets are provided in building blocks to connect them for stacking, then stacking functionality is improved, but structural strength deteriorates because the main housing has thin thickness and weak structural strength

Engineering Contradiction:
Improvestacking functionalityVSAvoidstructural strength
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The main housing is divided into a cylinder housing and a partition plate, with the partition plate further segmented into multiple magnet housings. This segmentation allows the magnetic components to be isolated in separate housings while the cylinder housing provides the primary structural support, resolving the contradiction between stacking functionality and structural strength.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The partition plate acts as an intermediary structure between the cylinder housing and the magnets. It provides a mounting surface for the magnet housings while being supported by the cylinder housing, thereby enabling magnetic stacking functionality without compromising the overall structural strength.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of manufacture

If the main housing has thin thickness to reduce weight and complexity, then ease of manufacture is improved, but durability deteriorates because it is prone to deformation and damage

Engineering Contradiction:
Improveease of manufactureVSAvoiddurability
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The housing is segmented into a cylinder housing and a partition plate, where the partition plate provides additional structural support to the thin-walled cylinder housing. This segmentation allows the main housing to maintain thin walls for ease of manufacture while the partition plate reinforces its durability and resistance to deformation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The main housing combines the cylinder housing with the partition plate to form a composite structure. The partition plate acts as a reinforcement element within the thin-walled cylinder housing, creating a composite structure that maintains ease of manufacture while significantly improving durability and resistance to external forces.

Inventive Principle:
Principle #40Composite materials

3Ease of operation

If cover bodies are detachably connected to main housing for easy assembly and disassembly, then ease of operation is improved, but structural strength deteriorates because cover bodies are easily detached

Engineering Contradiction:
Improveease of assembly and disassemblyVSAvoidconnection strength
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The connecting cylinder acts as an intermediary component between the cover body and the main housing. It provides a reliable connection interface that maintains ease of assembly and disassembly while ensuring sufficient connection strength through its integration with the partition plate and main housing structure.

Inventive Principle:
Principle #24Intermediary (Mediator)
