Solution Overview

Problem

Existing building blocks have a limited connecting mode, leading to a lack of interest and creativity in children's play, as they only allow for simple arrangements.

Innovation Solution

The introduction of building blocks with various connecting surfaces featuring protrusions and grooves, allowing for multiple connection types and structures, such as regular hexahedral, equilateral triangular prism, and other shapes, enabling diverse and complex constructions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If building blocks use a single connecting mode with simple arrangement, then the structure is simple and easy to manufacture, but the creativity and interest for children is limited

Engineering Contradiction:
Improveconnecting mode varietyVSAvoidconnecting structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The building block surface is segmented into multiple types of connecting surfaces (first connecting surface with protrusions and grooves, second connecting surface with only grooves, third connecting surface with only protrusions). This segmentation allows different connecting modes on different surfaces, increasing versatility while keeping each individual surface relatively simple.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The building blocks are designed with multi-functional connecting surfaces that can connect to different types of blocks (regular hexahedral, equilateral triangular prism, etc.) through various connecting modes. The protrusions and grooves serve multiple purposes: connecting adjacent blocks, connecting opposite blocks, and enabling different spatial arrangements, thus achieving universality.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If building blocks have multiple connecting surfaces with protrusions and grooves, then creativity and connection options are enhanced, but manufacturing complexity increases

Engineering Contradiction:
Improveconnection optionsVSAvoidmanufacturing complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The connecting surfaces are segmented into distinct functional zones (protrusion areas, groove areas, through hole areas) on different faces of the building block. This segmentation allows manufacturers to produce standardized components that can be systematically assembled, reducing overall manufacturing complexity despite the variety of connection options.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different surfaces of the building block have different local qualities: the first connecting surface has both protrusions and grooves for versatile connection, while the second and third surfaces have specialized features for specific connection modes. This local differentiation optimizes each surface for its intended function while maintaining manufacturability through modular design.

Inventive Principle:
Principle #3Local quality
