Interlocking Polymer Blocks for Mortarless Reusable Wall Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing construction methods using cinder blocks require skilled labor for assembly, are not reusable, and are prone to damage during storage, transportation, and use, leading to increased costs and structural misalignment.
Innovation Solution
The use of locking blocks made from polymers with interlocking mechanisms that self-align and reversibly secure together without mortar, allowing for efficient assembly and disassembly, and are fabricated using injection foam molding to enhance durability and reduce labor costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If cinder blocks are used with mortar assembly, then structural strength is achieved, but labor costs increase and reusability is lost
Solution Approach 1:
The patent replaces the mortar-based chemical bonding system with a mechanical interlocking system using protrusions and recesses. This substitution eliminates the need for skilled labor to apply and manipulate mortar, while maintaining structural strength through the mechanical engagement of complementary geometric features between blocks.
Solution Approach 2:
The interlocking features are designed to self-align and self-secure blocks during assembly. The protrusions and recesses automatically guide block placement and create secure connections without requiring skilled manual intervention, thereby reducing labor costs and increasing assembly productivity.
2Duration of action of stationary object
If cinder blocks are used for construction, then permanent structures are created, but reusability is eliminated
Solution Approach 1:
The patent transforms the static, permanent nature of traditional masonry into a dynamic, reconfigurable system. The mechanical interlocking features allow structures to be easily assembled and disassembled, enabling the same blocks to be reused for different applications. The connection strength is sufficient for permanent use when needed, but can be easily released when reusability is required.
3Strength
If cinder blocks are used in construction, then structural integrity is achieved, but block damage increases during handling
Solution Approach 1:
The patent uses composite materials combining concrete with polymeric or rubber components for the interlocking features. This composite construction provides the compressive strength of concrete while the polymeric elements absorb impact and resist chipping during handling, thereby improving block durability without compromising structural integrity.
4Manufacturing precision
If traditional masonry methods are used, then aligned walls are constructed, but skilled labor is required
Solution Approach 1:
The interlocking features are designed to self-align blocks during assembly. The geometric complementarity of protrusions and recesses automatically guides correct block placement and orientation, eliminating the need for skilled workers to achieve proper alignment. This self-aligning mechanism maintains manufacturing precision while dramatically reducing skill requirements.

AI summary
Disclosed herein is a product and methods of using that product for constructing walls and other structures. The product is a locking block that is designed for use in building walls and other structures quickly and inexpensively. The locking blocks are fabricated from polymers to form a robust physical structure that resists damage and provides for a relatively clean work space during assembly. The locking blocks include matching male and female features that reversibly secure the blocks together and are self-aligning to guide workmen on block placement during assembly. The design of the blocks eliminates the need to apply mortar or other adhesive methods to secure the blocks together, which greatly reduces labor costs as compared to typical construction products and methods. Because no mortar or other adhesive is used, the blocks can be efficiently and effectively disassembled and reused.
