Interlocking Concrete Block with Tapered Protrusions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing concrete blocks require mortar for assembly and are limited in reuse due to single-purpose design, making them inefficient for construction and disassembly.
Innovation Solution
Interlocking hollow concrete blocks with protrusions and cavities that allow for multiple positioning options, enabling assembly without mortar and facilitating easy disassembly for reuse.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If mortar is used to assemble concrete blocks, then the blocks are held together securely, but the assembly process becomes more complex and time-consuming
Solution Approach 1:
The patent replaces the chemical bonding system (mortar) with a mechanical interlocking system. The tongue and groove joints provide direct mechanical connection between blocks, eliminating the need for mortar while maintaining assembly stability. This substitution simplifies the assembly process by removing the mortar application step while still achieving secure block connection through the interlocking geometry.
2Reliability
If concrete blocks are designed for a single purpose, then they provide specialized functionality, but they cannot be reused for different construction purposes
Solution Approach 1:
The patent designs concrete blocks with standardized tongue and groove joint geometries that can accommodate multiple construction configurations. The consistent joint design across all blocks allows them to be used in various wall types, heights, and layouts, enabling reuse for different construction purposes while maintaining functional reliability through the proven interlocking mechanism.
3Strength
If traditional concrete blocks require mortar for assembly, then structural integrity is maintained, but disassembly and reuse become difficult
Solution Approach 1:
The patent segments the connection between blocks into discrete, reversible mechanical joints rather than a continuous chemical bond. The tongue and groove joints create individual connection points that can be separated without damaging the blocks, enabling easy disassembly and reuse while maintaining structural integrity during use through the interlocking geometry.

AI summary
An interlocking hollow concrete block (10) having two parallel long side walls (14) and two parallel short side walls (12) defining a hollow rectangular shape. Each of the two long side walls (14) and each of the two short side walls (12) have protrusions (20) on the top surface (16) and cavities (30) on the bottom surface (18). The protrusions (20) are identical in the width direction and the depth direction, and the protrusions (20) are tapered in the height direction. Each of the cavities (30) is configured to accommodate a protrusion (20) of a similar concrete block (10). The concrete block is further defined in that each of the long side walls (14) and the two short side walls (12) form an obtuse angle with the top surface (16) and each of the two long side walls (14) and the two short side walls (12) forms an acute angle with the bottom surface (18).
