Solution Overview

Problem

Existing toy building sets lack versatility, as body elements are often designed for specific figures, limiting the freedom to build diverse designs, and they fail to resemble real body parts, reducing appeal.

Innovation Solution

A toy building set with standardized body elements and complementary coupling means allows for interchangeable design and dressing elements, enabling the creation of various bone structures and designs, with snap functions and elastic deformation for secure mounting.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If body elements are designed for dedicated use in specific toy figures, then the figures can look like real body parts, but the freedom to build other figures is limited

Engineering Contradiction:
Improverealism of body partsVSAvoidfreedom to build different figures
Core Design Contradiction:
ShapeVSAdaptability or versatility

Solution Approach 1:

The body elements are segmented into standardized geometric shapes (cylinders, spheres, cones) that can be combined in various ways to create different body parts for different figures, rather than creating dedicated realistic parts for each figure type

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The standardized body elements are designed to serve multiple functions and can be used to construct various types of figures (human, animal, monster, robot) by combining them differently, making each element universally applicable across multiple figure designs

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

2Shape

If body elements are designed to look like real body parts, then the appeal to children is increased, but the versatility of the building set is reduced

Engineering Contradiction:
Improveappearance of body partsVSAvoidfreedom to build diverse figures
Core Design Contradiction:
ShapeVSAdaptability or versatility

Solution Approach 1:

Instead of creating monolithic realistic body parts, the design segments them into basic geometric forms that can be reconfigured to suggest different body parts through arrangement and combination

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Realism is achieved locally through the combination and arrangement of standardized elements rather than through the shape of individual elements themselves, allowing each element to maintain its universal applicability while the overall structure achieves realism

Inventive Principle:
Principle #3Local quality

3Adaptability or versatility

If standardized body elements are used for building bone structures, then the freedom to build different figures is increased, but the elements do not resemble real body parts

Engineering Contradiction:
Improvefreedom to build different figuresVSAvoidrealism of body parts
Core Design Contradiction:
Adaptability or versatilityVSShape

Solution Approach 1:

The design segments realistic body parts into basic geometric building blocks (cylinders for limbs, spheres for joints, cones for ears/tails) that can be assembled to create the appearance of realistic body parts while maintaining standardization

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Standardized geometric body elements are nested and combined in hierarchical structures to build up from simple geometric forms to complex realistic-looking body parts through multiple levels of assembly

Inventive Principle:
Principle #7Nested doll (Nesting)

AI summary

A toy building set comprising separate building elements adapted for building a toy figure, the building elements comprising a number of body elements (1, 2, 3) that are interconnected or adapted for being interconnected by means of articulated joints, and where the toy building set also comprises a number of dressing elements (5) and means for mounting the dressing elements on the body elements. The toy building set further comprises a number of design elements (4), and the at least one design element and at the least one body element has a first type of complementary coupling means (7) adapted for releasably mounting the design element on the body element, and where at least one dressing element and the design element has a second different type of complementary coupling means (8, 9) adapted for releasably mounting a dressing element on the design element, so that it is not possible to mount the dressing element on a body element.
