Drainage Channel Liner With Spring Inserts For Corrosion Containment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional drainage channels and trenches are prone to damage from corrosion, natural disasters, and environmental stresses, which can lead to the leakage of harmful or contaminated liquids into the environment, necessitating a secondary barrier for containment.
Innovation Solution
A drainage channel system comprising a primary barrier (channel) and a secondary barrier (liner) with a support mechanism, where the liner is secured within the channel using spring inserts or mechanical attachments, and optionally includes a sealant and moisture-sensing sensors to prevent leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional drainage channel is used, then it provides liquid containment, but it becomes cracked or split through corrosion, natural disaster, environmental effects, and stresses
Solution Approach 1:
The patent applies beforehand cushioning by installing a secondary liner barrier within the drainage channel before damage occurs. This liner acts as a pre-positioned protective layer that contains liquids even if the primary channel structure becomes cracked or corroded, thus cushioning against the consequences of potential failures.
Solution Approach 2:
The patent employs composite materials by combining the primary drainage channel structure with a secondary liner material. This creates a composite containment system where the liner provides enhanced corrosion resistance and damage tolerance, complementing the structural channel to improve overall reliability.
2Reliability
If a secondary barrier (liner) is added to the drainage channel, then containment reliability is improved, but device complexity increases
Solution Approach 1:
The patent applies the nested doll principle by placing the liner (secondary barrier) inside the drainage channel (primary structure). The liner is nested within the existing channel, creating a concentric containment system that improves reliability without requiring a completely separate external structure.
Solution Approach 2:
The patent uses a liner that functions as a flexible shell or thin film within the drainage channel. This flexible barrier provides effective containment while being simple to install and conform to the channel geometry, thereby improving reliability with minimal added complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively contains and redirects harmful liquids, providing a reliable secondary barrier to prevent environmental contamination and detecting potential leaks, ensuring the integrity of the drainage system.
Implementation Method 1
the liner is attached to spring inserts that are placed into a traditional drainage channel and the assembly is secured within the channel by the spring force of the inserts

AI summary
Embodiments of the present invention include a drainage channel comprising a first barrier for containment and a second barrier for containment. In one embodiment, the second barrier comprises a liner and a support. In a further embodiment, the support substantially secures at least a portion of the second barrier in the first barrier.
