Solution Overview

Problem

Traditional concrete construction blocks require mortar and skilled labor, leading to potential structural integrity issues and increased costs due to improper placement or excessive mortar use, and previous interlocking block systems were either too heavy or lacked sufficient compressive strength.

Innovation Solution

An interlocking construction block system that can form rigid structures without mortar, featuring internal channels for piping and reinforcing materials, and can be manufactured from various materials, including concrete, 3D-printed plastics, or expanded polystyrene foam, allowing for modular assembly in any length, width, or shape, with geometric sections that interlock in three axes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traditional concrete construction blocks are used, then structural strength can be achieved, but skilled labor and mortar are required, increasing construction time and cost

Engineering Contradiction:
Improveconstruction speedVSAvoidskilled labor requirement
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The construction block is divided into modular units with distinct interlocking features (protrusions and recesses) that enable assembly without skilled labor. Each block segment is designed with specific geometric features that guide proper placement and connection, eliminating the need for mortar and reducing construction time while maintaining structural integrity.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If previous interlocking block systems (Sparlock) were used, then assembly without mortar is achieved, but the blocks are too heavy and use excessive concrete material

Engineering Contradiction:
Improveassembly without mortarVSAvoidblock weight
Core Design Contradiction:
Ease of operationVSWeight of moving object

Solution Approach 1:

The construction block uses composite material construction combining concrete with lighterweight materials or optimized concrete formulations. This reduces the overall weight and material usage while preserving the interlocking capabilities that enable mortarless assembly, directly addressing the weight and material excess problems of previous systems like Sparlock.

Inventive Principle:
Principle #40Composite materials

3Ease of operation

If other dry stack systems (Haener, Azar blocks) were used, then assembly without mortar is achieved, but compressive strength is insufficient

Engineering Contradiction:
Improveassembly without mortarVSAvoidcompressive strength
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The block design incorporates pre-formed interlocking features and reinforcement elements during manufacturing. These preliminary structural preparations ensure that when blocks are assembled without mortar, the inherent geometry and embedded reinforcements provide sufficient compressive strength, overcoming the weakness of earlier dry-stack systems.

Inventive Principle:
Principle #10Preliminary action

4Reliability

If traditional blocks requiring mortar are used, then structural integrity can be maintained, but improper placement or excessive/insufficient mortar compromises safety and increases costs

Engineering Contradiction:
Improvestructural integrityVSAvoidassembly complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The construction block features self-aligning and self-leveling geometric characteristics that guide proper placement during assembly. The interlocking protrusions and recesses automatically position blocks correctly, eliminating reliance on mortar quantity and mason skill. This self-service mechanism ensures consistent structural integrity while simplifying the assembly process and reducing costs associated with mortar management and skilled labor.

Inventive Principle:
Principle #25Self-service

AI summary

An interlocking construction block system comprising a family of blocks that interlock along three axes, including a left/right axis, a front/back axis, and an up/down axis. The family of blocks are self-aligning and do not require skilled labor or mortar to create a structure of any length, width, height, or shape. Each block comprises a specific geometry that allows all blocks in the family to interlock in a woven pattern that not only locks the blocks in place but also allows even distribution of structural weights and stresses. The disclosed blocks can be manufactured in different sizes to conform to any building code requirement and to create wall lengths to a one-inch measurement. The blocks may comprise channel openings to allow for plumbing, electrical, and structural reinforcements in the structure and may each be reinforced with an internal mesh cage.
