Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flood barriers, such as sandbags and metal-framed structures, face issues like saturation, seepage, and catastrophic failure under fast-flowing water, and are often expensive and cumbersome for deployment and storage.
Innovation Solution
A flood mitigation barrier comprising a line of central structures wrapped in flexible heat shrinkable polymer material, with overlapping sections welded together to form a continuous impervious strip, and a layer of dry cement or cement/sand mix for sealing, which prevents water infiltration and enhances structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If sandbags are used as flood barriers, then they are easy to obtain and deploy, but they become saturated and are liable to increasing seepage and catastrophic failure
Solution Approach 1:
The patent applies a flexible heat-shrinkable polymer wrap around the central structures (sandbags or road barriers). This thin film enclosure provides an impervious barrier that prevents water saturation and seepage while maintaining the ease of deployment of the underlying simple structures. The wrap acts as a flexible shell that encapsulates the core elements, solving the seepage problem without complicating the deployment process.
Solution Approach 2:
The invention creates a composite barrier system combining the structural support function of simple materials (sandbags or road barriers) with the water-tight sealing function of the heat-shrinkable polymer wrap. This composite structure leverages the advantages of both components: the ease of deployment of the core structures and the impermeability of the polymer envelope, thereby resolving the contradiction between ease of manufacture and reliability.
2Strength
If metal-framed structures with tarpaulin cladding are used, then structural strength is improved, but the expense of material and complexity of assembly increase
Solution Approach 1:
The patent replaces the complex tarpaulin and chain assembly system with a heat-shrinkable polymer wrap that automatically conforms to the central structures when heated. This flexible shell approach eliminates the need for separate cladding materials and complex securing mechanisms, thereby reducing assembly complexity while maintaining structural integrity through the heat-shrunk envelope.
Solution Approach 2:
The invention substitutes the mechanical assembly system (tarpaulin draped over frames and secured with heavy chains) with a thermal processing system. The heat-shrinkable wrap is positioned around the central structures and then heated to cause automatic shrinkage and conforming, replacing complex mechanical fastening operations with a simpler thermal process that achieves the same structural reinforcement and water-tight sealing.
3Reliability
If heat shrinkable polymer material is used to wrap central structures, then impermeability and structural integrity are improved, but the cost of material increases
Solution Approach 1:
The patent employs a thin film heat-shrinkable polymer wrap that provides maximum impermeability and structural reinforcement with minimal material quantity. The heat-shrinking process allows the thin film to conform tightly to the central structures, creating an efficient barrier that prevents water infiltration while using less material than traditional thick tarpaulins or multiple layers of sandbags.
Solution Approach 2:
The invention utilizes the parameter change of the polymer material from a relaxed state to a heat-shrunk state. By applying heat, the polymer transitions to a contracted configuration that provides tight envelopment and structural reinforcement. This parameter change allows a single layer of relatively thin material to achieve the protective function that would otherwise require multiple thicker layers, thereby reducing overall material cost while maintaining reliability.
