Interconnected Erosion Control Blocks for Shoreline Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Shoreline erosion due to wave and hydrostatic forces poses a significant threat to bluffs, dunes, and river banks, leading to instability and potential landslides, as existing solutions fail to provide a flexible and adjustable erosion control system that can accommodate varying slopes and shapes.
Innovation Solution
A system of interconnected, adjustable concrete blocks with internal metal frames and linkage connectors that can pivot, allowing for flexible installation to follow natural contours and absorb wave energy, while also being removable and size-adjustable to suit different shoreline configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If rigid erosion control structures are used, then erosion resistance is improved, but adaptability to varying slope shapes and sizes deteriorates
Solution Approach 1:
The erosion control system is divided into multiple individual blocks that can be independently positioned and connected. Each block maintains structural integrity for erosion resistance while the segmented nature allows the overall system to adapt to varying slope geometries through selective arrangement and connection of blocks.
Solution Approach 2:
The system incorporates movable and adjustable connection mechanisms between blocks, allowing the structure to dynamically adapt to different slope configurations. The blocks can be positioned at various angles and heights to match the natural contour of the shoreline, providing both stability and adaptability.
2Adaptability or versatility
If custom-built erosion control structures are designed for specific sites, then adaptability to site conditions is improved, but manufacturing complexity and cost deteriorates
Solution Approach 1:
The erosion control blocks are designed as universal, standardized units that can be used across multiple different site conditions. The same block design serves various functions and can be adapted to different slope configurations through arrangement and connection methods rather than requiring custom manufacturing for each site.
Solution Approach 2:
By segmenting the erosion control system into standardized modular blocks, the design simplifies manufacturing while maintaining site-specific adaptability. The modular approach allows complex site requirements to be met through simple combinations of identical or similar pre-fabricated units.
3Reliability
If permanent erosion control structures are installed, then long-term protection is improved, but removability and reconfigurability deteriorates
Solution Approach 1:
The connection system between blocks is designed to be both stable for long-term protection and dynamically reconfigurable. Connection mechanisms allow blocks to remain firmly in place during storms while enabling easy removal and repositioning when site conditions change or maintenance is needed.
Solution Approach 2:
The modular block design facilitates recovery and reuse of erosion control components. Blocks can be removed from degraded or relocated sites and reused elsewhere, extending the service life of the materials and reducing long-term costs while maintaining effective protection.

AI summary
An erosion control system comprising a plurality of interconnected blocks that each include an upper face, a lower face, multiple sides, and connector recesses disposed on at least some of the sides, with each the connector recesses extending inwardly from an outer surface of the respective side at which it is disposed. Each block is configured to be connected with an adjacent block with one side of each block being disposed adjacent one side of an adjacent block and at least one connector recess of each block being aligned with one of the connector recesses of the adjacent block. The adjacent blocks are connected together at aligned connector recesses by a linkage assembly, with the adjacent blocks being able to pivot relative to each other via the linkage assembly.
