Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If construction elements use fixed interlocking joints only, then connection strength is improved, but functionality and versatility deteriorate due to inability to create movable connections

Engineering Contradiction:
Improveconnection strengthVSAvoidfunctionality
Core Design Contradiction:
StrengthVSAdaptability or versatility

Solution Approach 1:

The patent introduces movable interlocking joints that allow relative motion between connected elements while maintaining connection strength. This is achieved through special geometric designs of protrusions and recesses that enable controlled movement along specific trajectories, transforming static connections into dynamic ones and thereby improving functionality without sacrificing strength.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent divides the interlocking joint system into multiple types: fixed joints for stable connections and movable joints for flexible connections. This segmentation allows users to select appropriate joint types based on functional requirements, enabling both strong fixed structures and versatile movable mechanisms within the same construction kit.

Inventive Principle:
Principle #1Segmentation

2Ease of manufacture

If construction elements have simple interlocking joints, then ease of manufacture is improved, but connection options and versatility deteriorate

Engineering Contradiction:
Improveease of manufactureVSAvoidconnection options
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent designs universal base elements with standardized coordinate grids and multiple types of protrusions that can serve different functions. The same base element can participate in fixed connections, movable connections, or support various structures, reducing the number of different零件 needed while increasing connection options through multi-functional design.

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

Solution Approach 2:

The patent applies different protrusion designs (cross-shaped, tubular, plate-like, corner elements) at specific locations on the base according to the coordinate grid system. Each local region of the base has optimized protrusions for specific connection needs, allowing versatile connections while maintaining a uniform manufacturing process for the entire element.

Inventive Principle:
Principle #3Local quality

3Adaptability or versatility

If construction elements use multiple protrusion groups with complex geometry, then connection versatility is improved, but device complexity deteriorates

Engineering Contradiction:
Improveconnection versatilityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent uses asymmetric protrusion designs (cross-shaped with different arm orientations, corner elements with specific shelf configurations) that provide directional connection capabilities. This asymmetry enables versatile connections in different orientations and configurations while maintaining relatively simple individual element geometries that are easy to manufacture.

Inventive Principle:
Principle #4Asymmetry

Solution Approach 2:

The patent utilizes the vertical dimension by positioning protrusions at different heights and orientations relative to the base plane. This three-dimensional arrangement of protrusions on a two-dimensional coordinate grid allows multiple connection options without increasing the horizontal footprint or overall element complexity.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

The invention relates to construction kit elements for use in children's building sets and in puzzles. A construction element according to a first variant comprises a flat rectangular base and a connecting unit. The connecting unit is comprised of four groups of projections. The projections of the first group are tubular and have an annular cross-section. The projections of the second group are tubular and have a square cross-section. The projections of the third group are in the form of rectangular plates with projecting shoulders. In the fourth group the projections are disposed in the corners of the base and are in the form of L-shaped members. A second variant of the construction kit element comprises three of the four groups of projections. The variants of the invention provide construction kit elements with enhanced functional capabilities.
