Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional seawall systems are not resilient and do not effectively utilize wave energy to prevent shoreline erosion, leading to structural integrity issues and damage to surrounding properties, while also failing to coexist with natural habitats and aesthetic considerations.
Innovation Solution
A modular interlocking seawall diversion system that diverts incoming waves through step-shaped sections and overflow deflectors, using foundation pilings with sheared attachments and indigenous aquatic habitat elements to absorb and redirect wave energy, while providing a recreational platform and supporting aquatic life, made from composite materials like fiberglass reinforced plastic.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If solid sheet pile or concrete break walls are used to absorb 100% of wave energy, then wave energy is fully absorbed, but structural integrity is weakened and surrounding properties are damaged
Solution Approach 1:
The seawall is divided into modular sections with varying porosity levels, allowing different portions to handle wave energy differently. The system segments wave energy dissipation across multiple modules rather than concentrating it in a single solid structure.
Solution Approach 2:
Different sections of the seawall have different porosity characteristics - some areas are more porous while others are denser. This local variation in material properties allows the structure to absorb wave energy in specific zones while protecting surrounding properties in other zones.
2Loss of energy
If steel cage fill with stones (revetment) is used to absorb 75-80% of wave energy, then wave energy is partially absorbed, but stones are moved by wave force causing structure to weaken over time
Solution Approach 1:
The system uses porous concrete and modular units with controlled porosity to absorb wave energy. The porous structure allows water to penetrate and dissipate energy while the interlocking modular design prevents individual units from being moved by wave forces.
Solution Approach 2:
The seawall combines porous concrete with geosynthetic reinforcement and interlocking modular elements to create a composite structure that maintains structural integrity while absorbing wave energy through its porous architecture.
3Reliability
If conventional seawall systems are used to prevent erosion, then shoreline protection is provided, but natural habitats and aesthetic considerations are compromised
Solution Approach 1:
The modular seawall system serves multiple functions: shoreline protection, habitat creation, and aesthetic enhancement. The same structure that prevents erosion also provides habitats for marine life through its porous design and can be configured in various aesthetic patterns.
Solution Approach 2:
The porous concrete modules create interstitial spaces that serve as habitats for marine organisms while maintaining the structural integrity needed for shoreline protection. The porosity allows water flow that supports aquatic ecosystems.

Implementation Method 1
divertor sections defining a rear face and an opposing front face that orients towards incoming waves... divertor sections comprising multiple steps consisting of a curved riser and a tread... configured to redirect incoming waves
Implementation Method 2
the foundation pilings having one or more longitudinal grooves configured to enable flowage of a porous material that encourages aquatic growth from the top end to the bottom end
Implementation Method 3
the face, planter 116a, of the indigenous aquatic habitat planter assembly 117 is a generally bowl shaped housing with a curved face that is configured to slope upwardly from about 35 degrees from the bottom of the bowl to the rim that absorbs and diverts wave energy outwardly toward the incoming wave

AI summary
An interlocking modular smart seawall diversion and recreation system provides step-shaped diverter sections arranged side-by-side along a shoreline. The diverter sections slope from a base end up towards an upper end. To break kinetic energy of waves, and divert waves, the diverter sections form steps with curved risers and horizontal treads. The system forms a diversion path for the waves that reach the upper end of the modular walls and recirculate the wave energy back to divertor chamber and natural environment. Foundation pilings project into the ground and extend up to support the wall sections. The bottom end of foundation pilings terminates at sheared attachments having a tapered cross section and an edge for securely anchoring into the ground. A platform atop the diverter sections provides a pathway; a lighted platform for recreational activities; and transparent skylight portals for observing aquatic wildlife in water below and creating an indigenous ecosystem.
