Solution Overview

Problem

Existing flood control methods, such as using sandbags, are inefficient and labor-intensive, failing to effectively prevent floods and requiring significant manpower and time, while urban areas face increasing risks from floods and other natural disasters.

Innovation Solution

Development of an automatic lifting flood control and water retaining wall system made of recyclable waterproof rubber and plastic, which can be quickly assembled and disassembled by a few people, featuring inflatable pontoons and traction systems to resist flood pressure and guide water flow, and modular components for flexible installation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traditional sandbags are used to build walls for flood control, then flood prevention function is provided, but significant manpower and time are required making it labor-intensive and inefficient

Engineering Contradiction:
Improveflood control efficiencyVSAvoidemergency response time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The flood control system is divided into modular units that can be independently deployed and connected. Each module contains integrated components (barrier, pontoon, anchoring) that work together, allowing rapid assembly without requiring large numbers of workers to manually place sandbags.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The flood control modules are pre-assembled with all necessary components (barrier panels, pontoons, anchoring systems) prepared in advance. This preliminary preparation eliminates the need for on-site construction activities, enabling immediate deployment when flooding occurs.

Inventive Principle:
Principle #10Preliminary action

2Productivity

If traditional sandbags are used for flood control, then water blocking function is achieved, but large amounts of manpower are required increasing labor cost and intensity

Engineering Contradiction:
Improveflood control efficiencyVSAvoidlabor intensity
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The flood control module is designed to be self-deploying through mechanical advantage systems. The lever arm mechanism allows a small input force to generate sufficient lifting force to raise the barrier, and the pontoon provides automatic buoyancy to maintain barrier position without continuous human intervention.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The manual labor-intensive process of stacking and securing sandbags is replaced by a mechanical lever system that uses hydraulic or mechanical advantage to lift and position the barrier automatically. This substitution reduces labor intensity from requiring many workers to potentially one or two operators.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Adaptability or versatility

If inflatable pontoons are used to lift the flood control wall, then automatic adaptation to rising water levels is achieved, but the system becomes more complex

Engineering Contradiction:
Improveadaptation to water level changesVSAvoidsystem structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The pontoon's buoyancy parameter is changed dynamically through inflation and deflation. As water levels rise, the pontoon is inflated to increase displacement and lift the barrier higher. When water levels fall, the pontoon is deflated to reduce lift. This parameter change provides automatic adaptation without complex control systems.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The system uses pneumatic inflation of the pontoon to generate lifting force. Air pressure is introduced to inflate the pontoon, creating buoyant force that automatically adjusts to water levels. This pneumatic mechanism provides a simple yet effective way to achieve adaptability without complex mechanical or electronic systems.

Inventive Principle:
Principle #29Pneumatics and hydraulics

4Loss of time

If the flood control device is designed for rapid assembly, then emergency response time is reduced, but the structural complexity may increase

Engineering Contradiction:
Improveassembly timeVSAvoidmodular component complexity
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The flood control system is segmented into standardized modules that can be manufactured separately and assembled quickly on-site. Each module contains pre-configured components (barrier panel, pontoon, anchoring elements) that interface through simple connection mechanisms, enabling rapid assembly without complex field construction.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Multiple functions are merged into single integrated components. The barrier panel incorporates connection elements, the pontoon includes anchoring attachments, and the lever arm integrates both mechanical advantage and positioning functions. This merging reduces the number of separate parts to assemble while maintaining functionality.

Inventive Principle:
Principle #5Merging (Combining)
