Trapezoidal Concrete Blocks for Mortar-Free Wall Construction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Standard rectangular concrete blocks allow water to seep into joints during wall construction, requiring costly masonry techniques and skilled labor for corner adjustments, and are time-consuming to align properly.
Innovation Solution
The development of trapezoidal-shaped concrete blocks with interlocking capabilities, featuring specialized shapes for corners and angles, allowing water to run down the wall surface and preventing joint infiltration, and enabling quick and easy wall construction without mortar.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If rectangular concrete blocks are used for wall construction, then the wall structure is simple and easy to manufacture, but water easily penetrates into the joints between blocks
Solution Approach 1:
The patent applies asymmetry by changing the block shape from rectangular to trapezoidal, with the front face sloping inward from bottom to top. This asymmetric geometry causes water to run down the sloped surface away from the joints, preventing water penetration while maintaining manufacturing simplicity through standard concrete forming techniques.
2Ease of manufacture
If rectangular concrete blocks are used for wall construction, then the blocks are easy to manufacture with standard dimensions, but corner adjustments require costly masonry techniques and skilled labor
Solution Approach 1:
The patent applies segmentation by providing a complete set of trapezoidal blocks with different configurations (standard blocks, corner blocks, cap blocks, bullnose blocks) that can be assembled like modular components. This allows corners and architectural features to be built using pre-designed block variations rather than requiring skilled masons to cut and shape individual blocks, reducing labor costs while maintaining manufacturing simplicity.
3Productivity
If rectangular concrete blocks are used for wall construction, then the wall assembly process is straightforward, but proper alignment is time-consuming
Solution Approach 1:
The patent applies self-service through self-aligning features including recesses and protrusions on block faces that automatically guide blocks into correct positions during assembly. The trapezoidal geometry and interlocking features cause blocks to self-align vertically and horizontally without requiring time-consuming manual measurement and adjustment, thereby increasing productivity while minimizing alignment time.

AI summary
The present invention relates to concrete blocks or cement blocks that are shaped along the front surface like a wood shingle. In this way, when a user builds an outside wall out of these cement blocks, water will run down the side of the wall and not get into any of the joints where one block connects with the other. The blocks are all pre-made, sent to an end-user, and the end-user stacks them to create a wall.
