Solution Overview
Problem
Existing interlocking concrete masonry systems face challenges in constructing stable walls beyond one story without reinforcement, and require mortar for stability, while also lacking efficient integration of insulation and utility conduits.
Innovation Solution
Incorporation of vertical radius corners and edges, chamfered edges for mechanical fasteners, hollow cavities for reinforcement or conduits, and modular block designs allowing for interlocking without mortar, including unitary corners and intersecting blocks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional interlocking concrete masonry blocks are used, then walls can be constructed without reinforcement for one story, but the system cannot support multi-story construction and requires mortar for stability
Solution Approach 1:
The block is divided into multiple functional segments: interlocking portions with radius corners/edges for structural stability, chamfered edges for fastener accommodation, hollow cavities for reinforcement/conduits, and unitary corner blocks for geometric stability. This segmentation allows each portion to address specific construction requirements without requiring mortar.
Solution Approach 2:
The block system combines different geometric features (radius corners, chamfered edges, flat surfaces, grooves) within a single concrete masonry unit to create a composite structural system that provides both interlocking stability and accommodation for reinforcement/conduits without requiring additional mortar materials.
2Adaptability or versatility
If blocks are made with enlarged spaces for insulation and conduits, then integration of utilities is improved, but block weight increases
Solution Approach 1:
Hollow cavities are nested within the block structure, with dividing walls creating separate chambers. These cavities accommodate insulation and utility conduits without requiring the blocks to be significantly larger or heavier, as the cavities utilize the existing block volume efficiently.
Solution Approach 2:
The block design incorporates three-dimensional features including hollow cavities, dividing walls, and vertical radius corners/edges that provide structural stability while accommodating utilities. This dimensional complexity allows multiple functions within a single block without proportionally increasing weight.
3Reliability
If vertical radius corners and edges are added to interlocking portions, then block breakage decreases and flexibility increases, but manufacturing precision requirements increase
Solution Approach 1:
Vertical radius corners and edges are incorporated into the interlocking portions of the blocks. These curved features provide flexibility and reduce stress concentration during block interaction, decreasing breakage. The radius dimensions (6mm to 12mm) are specified to balance durability with manufacturability.
4Ease of operation
If chamfered edges are added to provide space for mechanical fasteners, then insulation and cladding attachment is enabled, but block geometry complexity increases
Solution Approach 1:
Chamfered edges are applied locally at specific locations on the blocks where fastener installation is required, rather than modifying the entire block geometry. This localized approach enables insulation and cladding attachment while minimizing overall geometric complexity.

AI summary
The present invention is an improvement on a previous version of an interlocking building block system for use in constructing a building wall. The improvements introduced are radii corners and chamfered edges that allow for claddings to be attached to the wall by leaving space for mechanical screws to be secured between two blocks. Furthermore, the radii corners allowed for increased mechanical movement between two interlocking blocks, resulting in greater durability of the blocks. The improvement also include a corner block and an intersecting block which replace the need for using multiple blocks to create intersecting points or corners. Some blocks also contain an additional hollow cavity with channels to allow increased support members to be introduced between blocks, thus increasing the height of the walls that can be built using the block system.
