Solution Overview

Problem

Blocks used for construction or toys often shift or rotate when not coupled, leading to instability in their arrangement.

Innovation Solution

The design incorporates connective protrusions on each block side, including middle and lateral connective protrusions, which allow blocks to couple securely by engaging with corresponding protrusions on adjacent blocks, creating a stable block system.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If blocks are stacked or disposed next to one another without coupling mechanisms, then the blocks are simple to manufacture and use, but the blocks shift, rotate, or stray from their desired arrangement

Engineering Contradiction:
Improvearrangement stabilityVSAvoidblock structure complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The block is divided into distinct functional segments: a base portion and a connective protrusion. The connective protrusion is further segmented into a middle connective protrusion and lateral connective protrusions, each serving specific coupling functions. This segmentation allows the block to maintain stability through specialized coupling elements while keeping the overall design modular and manageable.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The connective protrusions act as intermediary elements between blocks. The middle connective protrusion engages with corresponding protrusions on adjacent blocks to prevent shifting, while lateral connective protrusions prevent rotation. These intermediary features mediate the interaction between blocks to achieve stable arrangements.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Stability of the object's composition

If connective protrusions are added to blocks to prevent shifting and rotation, then arrangement stability is improved, but the manufacturing complexity increases

Engineering Contradiction:
Improvearrangement stabilityVSAvoidblock manufacturing ease
Core Design Contradiction:
Stability of the object's compositionVSEase of manufacture

Solution Approach 1:

The middle connective protrusion and lateral connective protrusions are merged into a single integrated block structure rather than being separate components. This combining of multiple coupling features into one monolithic block simplifies manufacturing processes compared to assembling separate coupling elements, while still providing comprehensive stability against shifting and rotation.

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If multiple connective protrusions are included on each block side, then the blocks couple securely to prevent shifting and rotation, but the device complexity increases

Engineering Contradiction:
Improvecoupling reliabilityVSAvoidblock structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

Different regions of the block serve different coupling functions: the middle connective protrusion is positioned to primarily prevent shifting, while lateral connective protrusions are positioned to primarily prevent rotation. This local specialization of coupling functions allows each protrusion to be optimized for its specific purpose, improving overall coupling reliability while maintaining a relatively simple overall structure.

Inventive Principle:
Principle #3Local quality

AI summary

A block may comprise a base comprising a first block side comprising a first side plane and a connective protrusion coupled to the base and extending distally outwardly and substantially perpendicularly from the first side plane. The connective protrusion may comprise a center pillar coupled to the base extending distally outward from the first side plane, a base portion coupled to the center pillar and the base and extending axially and substantially perpendicularly from the center pillar in a first direction, and an overhang portion coupled to the center pillar extending axially and substantially perpendicularly from the center pillar in a second direction opposite the first direction such that there is an overhang space between the first side plane and the overhang portion. The block may further comprise additional connective protrusions, and the connective protrusions of multiple blocks may enable the coupling of such blocks.
