Fluidized Aggregate Separation for Beach Restoration

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Beach restoration projects face downtime and efficiency issues due to rock boxes filling up with oversized stones, requiring frequent cleaning and halting the sand deposition process, as existing systems fail to continuously separate and remove large rocks from the aggregate mixture.

Innovation Solution

A fluidized aggregate separation system that includes an intake assembly, a velocity reduction chamber, a separation assembly with a movable screen to filter out oversized materials, and a deflector assembly to direct smaller materials to the restoration site while continuously removing oversized materials to a remote location.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If rock boxes are used to collect oversized rocks at the end of the discharge pipe, then the beach can be protected from contamination with larger stones, but the rock boxes rapidly fill up requiring frequent cleaning and process downtime

Engineering Contradiction:

Improvebeach contamination with oversized rocksVSAvoidrestoration process efficiency

Core Design Contradiction:

Object-affected harmful factorsVSProductivity

Solution Approach 1:

The system performs preliminary separation of oversized rocks from the aggregate mixture at the intake end of the pipeline, before the material is pumped to the beach. This prevents oversized rocks from reaching the discharge pipe and rock boxes, eliminating the need for frequent cleaning and maintaining continuous operation.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system extracts and removes oversized rocks from the aggregate mixture at the source (intake end) rather than collecting them at the discharge end. This extraction approach prevents the rock boxes from filling up and eliminates process downtime associated with cleaning.

Inventive Principle:

Principle #2Taking out (Extraction)

2Reliability

If the system stops frequently to clean rock boxes, then the rock boxes remain functional for collecting oversized rocks, but the restoration process experiences significant downtime and slowdown

Engineering Contradiction:

Improverock box functionalityVSAvoidprocess downtime

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system enables continuous operation by separating oversized rocks at the intake end, allowing the pump and discharge operations to proceed without interruption. The separation process occurs continuously as material flows through the pipeline, eliminating stoppages for rock box cleaning.

Inventive Principle:

Principle #20Continuity of useful action

3Productivity

If a separation system is implemented at the intake end of the pipeline, then continuous operation can be maintained by preventing oversized rocks from entering the pump, but the system complexity increases with additional equipment

Engineering Contradiction:

Improvecontinuous operation capabilityVSAvoidseparation system structure

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The system divides the aggregate mixture separation function into a dedicated intake end separation unit with screening apparatus. This segmentation allows the separation function to be performed independently at the source, enabling continuous operation without requiring complex modifications to the entire pipeline system.

Inventive Principle:

Principle #1Segmentation
