Interlocking Block Geometry for Dry-Stack Multi-Story Walls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing interlocking concrete masonry systems face challenges in constructing multi-story walls without reinforcement, require mortar for stability, and have issues with block breakage due to sharp corners and edges during assembly.
Innovation Solution
Incorporation of vertical radius corners and edges, chamfered edges for mechanical fasteners, hollow cavities for reinforcement or utility conduits, and improved block designs such as unitary corners and intersecting blocks to facilitate dry-stack construction of load-bearing and non-load-bearing walls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If sharp corners and edges are used on blocks, then manufacturing is simpler, but block breakage increases during assembly
Solution Approach 1:
The patent applies curvature by replacing sharp corners and edges with rounded profiles on the blocking components. Specifically, the abutment portions and connecting portions feature rounded outer surfaces that reduce stress concentration during assembly and loading, thereby preventing block breakage while maintaining manufacturing feasibility through standard forming processes
2Productivity
If blocks are designed for dry-stack construction without reinforcement, then construction is simpler and faster, but stability and load-bearing capacity are reduced
Solution Approach 1:
The patent segments the block into distinct functional portions: abutment portions for vertical stacking and load transfer, connecting portions for horizontal interlocking, and recesses for mechanical fasteners. This segmentation enables dry-stack construction with inherent stability through the interlocking geometry itself, eliminating the need for reinforcement while maintaining wall stability
Solution Approach 2:
The patent merges multiple stabilization functions into the block geometry itself: the interlocking connecting portions and abutment portions create a unified structural system that provides both horizontal and vertical stability, while the recesses integrate fastener attachment points directly into the block design, eliminating the need for separate reinforcement elements
3Stability of the object's composition
If mortar is used to secure blocks, then wall stability is improved, but construction complexity and time increase
Solution Approach 1:
The block design provides self-service stabilization through its own geometry. The abutment portions and connecting portions are shaped to automatically align and secure adjacent blocks together without requiring external bonding materials like mortar. The recesses and protrusions create a mechanical interlocking system that maintains wall stability through the block design itself
4Adaptability or versatility
If block dimensions are reduced to fit standard wall thicknesses, then construction standardization is improved, but the ability to accommodate mechanical fasteners and insulation is reduced
Solution Approach 1:
The patent applies local quality by creating recesses and receiving portions at specific locations on the block surfaces where mechanical fasteners and insulation are needed. These localized features provide the necessary volume for fastener accommodation without requiring the entire block to be enlarged, maintaining standardization while enabling fastener installation

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.
