Dry Cast Block Irregular Edge Profiles for Seamless Joints
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing landscape blocks, such as retaining wall blocks and cap blocks, often exhibit visible joints when assembled, disrupting the seamless appearance of a continuous wall, making it difficult to simulate natural rock or stone appearances effectively.
Innovation Solution
The use of dry cast blocks with non-planar topographical definitions and irregular profile shapes on their exposure faces, where one block's edge is a mirror image of another's, allowing for seamless alignment and a smooth appearance when adjacent blocks are arranged.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If traditional blocks with straight edges are used, then manufacturing is simple, but visible joints appear between adjacent blocks disrupting the seamless appearance
Solution Approach 1:
The patent applies asymmetry by designing block edges with irregular, non-symmetric profiles where convex portions on one block align with concave portions on adjacent blocks. This asymmetric interlocking design creates seamless joints that are difficult to detect, resolving the contradiction between appearance continuity and manufacturing simplicity by incorporating moderate geometric complexity into the block edges.
Solution Approach 2:
The patent applies local quality by making only the edge portions of the blocks complex with irregular profiles, while the main body of the blocks remains simple and easy to manufacture. This localized application of complexity to specific regions (the edges) allows seamless appearance without significantly increasing overall manufacturing difficulty.
2Shape
If blocks with irregular profile shapes are used, then seamless appearance is achieved, but manufacturing precision requirements increase
Solution Approach 1:
The patent applies preliminary action by pre-forming the irregular edge profiles during the block manufacturing process itself, rather than requiring field adjustment or post-manufacturing alignment. The blocks are manufactured with their final irregular shapes already incorporated, and the design ensures that standard manufacturing tolerances are sufficient to achieve the desired seamless appearance when blocks are assembled.
3Shape
If non-planar topographical definitions are used on exposure faces, then natural rock appearance is simulated, but the complexity of block design increases
Solution Approach 1:
The patent applies local quality by applying complex non-planar topographical definitions only to the exposure faces of the blocks that are visible in the finished structure, while keeping the non-exposure faces simpler. This localized application of complexity to specific regions (exposure faces) allows natural rock appearance simulation without significantly increasing overall block design complexity.

AI summary
A first concrete block has an exposure face with a non-planar first topographical definition and a first edge along the side face and a second edge along the second side face. The first edge has a first irregular profile. A second concrete block has an exposure face with a non-planar second topographical definition and a first edge and a second edge. The second topographical definition is different from the first topographical definition. The second edge of the second block has an irregular profile that is the mirror image of the first irregular profile. The blocks can be oriented adjacent and against each other for a seamless appearance. Assembling methods include orienting the first side of the first block against the second side of the second block and aligning the first irregular profile of the first block with the first irregular profile of the second block for a seamless appearance.
