Mortarless Interlocking Block for Rapid Wall Construction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mortarless interlocking building block systems are costly to produce and require multiple block types and sizes, as well as additional finishing processes, making them inefficient for rapid construction with unskilled labor.
Innovation Solution
A single, lightweight, injection-molded plastic block with interlocking Maltese sockets and protrusions that can be easily cut into various sizes at the construction site, eliminating the need for corner blocks and various incremental sizes, and featuring a zero absorption rate for water resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple block types and sizes are used to accommodate various wall configurations, then adaptability is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent applies universality by designing a single standardized block that can serve multiple functions through simple modifications. The block features universal interlocking mechanisms (protrusions and recesses) that work the same way regardless of block orientation or position, allowing one block design to replace multiple specialized block types while maintaining adaptability for various wall configurations including corners and openings
2Manufacturing precision
If grooves or sockets and protrusions or connectors are cut into blocks after molding, then manufacturing precision is improved, but ease of manufacture and productivity worsen
Solution Approach 1:
The patent applies preliminary action by incorporating all interlocking features (sockets and protrusions) directly into the mold during the initial block formation process. This eliminates the need for subsequent cutting or finishing operations, as the precise interlocking geometry is created upfront during molding, thereby improving both manufacturing precision and ease of manufacture simultaneously
Solution Approach 2:
The patent extracts the complex finishing operations (cutting grooves, sockets, and protrusions) from the manufacturing process by integrating them into the mold design. This separation of the interlocking feature creation from post-molding operations eliminates costly and time-consuming secondary processing while maintaining precise dimensions
3Adaptability or versatility
If corner blocks of various lengths are provided to size walls, then adaptability is improved, but device complexity and inventory requirements increase
Solution Approach 1:
The patent applies segmentation by designing the wall construction system using only standardized-length blocks that can be systematically combined and staggered. Instead of requiring pre-fabricated corner blocks of various lengths, the system segments the wall into modular units that can be assembled in different configurations using the same basic block, thereby reducing inventory requirements while maintaining adaptability
4Strength
If blocks are made heavier to increase strength, then strength is improved, but ease of operation and construction speed worsen
Solution Approach 1:
The patent applies composite materials by using concrete or cement-based composite material that provides high strength-to-weight ratio. The composite nature of the material allows the block to achieve structural strength comparable to or exceeding traditional masonry while being lighter and easier to handle, thereby improving both strength and ease of operation simultaneously
