Solution Overview

Problem

Conventional flood barriers, such as sandbags and inflatable tubes, are labor-intensive, costly, and pose environmental hazards due to contamination and instability, with inflatable barriers being prone to rupture from internal pressures and debris.

Innovation Solution

A rapidly deployable, collapsible flood barrier system comprising elongated, inflatable crossbeams within water-impermeable cover tubes that can be easily assembled and disassembled, secured to the ground, and inflated to form a continuous containment system, using extruded PVC materials and RF welding for durability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If sandbags are used to contain flooding rivers, then flood containment is achieved, but labor and logistic costs increase enormously

Engineering Contradiction:
Improveflood containmentVSAvoiddeployment efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The flood barrier is divided into modular sections that can be independently handled and deployed. Each section is a self-contained unit with inflatable crossbeams housed in tubes, allowing for easier transport and assembly compared to traditional sandbags that require individual filling and stacking.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention uses inflatable crossbeams filled with air to create the barrier structure. The inflation process transforms flat, collapsible tubes into rigid, flood-resistant barriers, eliminating the need for manual stacking and reducing deployment time significantly.

Inventive Principle:
Principle #29Pneumatics and hydraulics

2Reliability

If burlap sandbags are deployed, then flood containment is provided, but they require extensive decontamination or special disposal arrangements

Engineering Contradiction:
Improveflood containmentVSAvoidcontamination
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The barrier uses a flexible tubular structure made of durable material that can be easily cleaned and reused. The smooth, non-porous surface of the inflated tube resists contamination better than porous burlap, and the entire structure can be deflated and stored for future use without environmental harm.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The inflatable crossbeam system is designed to be recovered and reused multiple times. After flood events, the barrier can be deflated, collapsed, and stored for future deployment, eliminating the need for disposal of entire barrier structures and reducing environmental contamination risks.

Inventive Principle:
Principle #34Discarding and recovering

3Ease of operation

If water inflatable cylindrical tubes are used, then deployment is simplified, but they suffer instability and require extensive decontamination

Engineering Contradiction:
Improvedeployment simplicityVSAvoidbarrier stability
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The barrier is segmented into multiple inflatable crossbeams housed within separate tubes, allowing for distributed stability throughout the structure. This modular approach provides multiple support points that work together to maintain stability while simplifying deployment of individual sections.

Inventive Principle:
Principle #1Segmentation

4Productivity

If monolithic inflatable barriers are used, then deployment is rapid, but they are susceptible to catastrophic failure

Engineering Contradiction:
Improvedeployment speedVSAvoidbarrier reliability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The barrier is divided into multiple independent inflatable crossbeams that can be inflated separately within individual tubes. This segmentation means that if one section is damaged, the others can continue to provide flood containment, eliminating catastrophic failure of the entire barrier system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The tubular housing structure provides protective cushioning for the inflatable crossbeams before they are inflated. The tubes act as a protective shell that can absorb damage from debris and environmental factors, preventing direct damage to the inflatable elements and reducing the risk of catastrophic failure.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

AI summary

The present invention is a rapidly deployable flood defense system and method that has at least one barrier cover, each comprising a plurality of laterally-extending crossbeam housing tubes stacked generally vertically and housing an inflatable crossbeam disposed within the tube, an end retaining tab at each end of the tube, and a plurality of rear support retaining tabs spaced along the lateral length of the crossbeam housing tube; and a front apron and a rear apron. The system also has a plurality of support tubes and a plurality of additional support tubes positioned along the lateral length of the crossbeam housing tube. Each support tube held in the generally vertical direction by a base post and each and additional support tube positioned along the lateral length of the crossbeam housing tube having an additional base post positioned rearwardly.
