Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coastal and river bank erosion defense structures face challenges such as lengthy construction schedules, labor-intensive installation, and inefficiencies due to wave battering, with alternatives like sheet iron piling and sandbags being prone to collapse or saturation.
Innovation Solution
A modular building block apparatus comprising interconnected blocks with male and female engagement portions, drainage channels, and connector members, made from impermeable materials like geopolymer cement, allowing for customizable and stable wave resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional seawalls and gabions are constructed, then coastal protection is provided, but construction time is extended and labor requirements increase
Solution Approach 1:
The coastal protection structure is divided into modular blocks that can be independently manufactured and assembled. Each block contains integrated connection features allowing rapid assembly without extensive labor, directly reducing construction time while maintaining protective reliability through the modular interlocking system
Solution Approach 2:
Blocks are pre-manufactured with integrated connection features, drainage channels, and reinforcement elements before site delivery. This preliminary preparation eliminates on-site construction complexity and reduces installation time while ensuring consistent protective performance
2Ease of operation
If sheet iron piling is installed, then installation is simplified, but structural stability deteriorates under wave battering
Solution Approach 1:
The block structure combines multiple materials including concrete, steel reinforcement, and geotextiles to create a composite system that maintains simplicity of installation while achieving superior structural stability under wave forces through material synergies
Solution Approach 2:
The structure is segmented into modular blocks with integrated connection mechanisms that simplify installation while distributing wave forces across multiple units, enhancing overall structural stability compared to continuous sheet piling
3Productivity
If sandbags are used to create artificial dunes, then installation is quick, but water saturation causes failure
Solution Approach 1:
The block structure incorporates controlled porous elements and drainage channels that allow rapid water passage, preventing saturation buildup while maintaining structural integrity. This enables quick installation like sandbags while eliminating water saturation failure modes
Solution Approach 2:
Rather than preventing water contact entirely, the design converts the harmful effect of water saturation into a beneficial drainage function, allowing water to pass through controlled pathways while maintaining structural stability and installation speed
4Object-affected harmful factors
If modular blocks with drainage channels are assembled, then water drainage is improved, but assembly complexity increases
Solution Approach 1:
Multiple functions including structural support, water drainage, and interconnection are merged into single integrated block units. The drainage channels are built into the block structure itself rather than added separately, improving water drainage while avoiding increased assembly complexity

AI summary
A modular building block apparatus for the construction of a coastal or river bank erosion defence or protection structure includes a plurality of blocks arranged in stacked rows, the blocks in each row having cooperating formations whereby the blocks in each row are interconnected with one another. Apertures formed in each block extend perpendicular to the rows, and a plurality of connector members extend through aligned apertures in adjacent rows of the blocks to interlock the rows to one another.
