3-Ply Cargo Bay Liner Structure for Moisture Drainage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing recreational vehicle and cargo trailer liners made of corrugated plastic materials are prone to water ingress and structural damage due to moisture accumulation in the sinusoidal channels, leading to potential ripping or tearing.
Innovation Solution
A 3-ply panel liner with a core having projections and openings, where the core is made from polypropylene and is 100% recyclable, is used, which provides sufficient rigidity and protects the undercarriage while allowing moisture to escape, and can be combined with aluminum foil or metalized film and woven or nonwoven fabric for added insulation and protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If corrugated plastic liner material is used, then the liner provides basic protection and flexibility, but water accumulates in the sinusoidal channels causing structural damage and ripping
Solution Approach 1:
The liner incorporates a porous drainage layer that allows water to pass through the sinusoidal channels without accumulating, preventing the structural damage and ripping that occurs with water accumulation in traditional solid corrugated liners
Solution Approach 2:
The liner uses a composite structure combining multiple materials: a top protection layer, a sinusoidal drainage core, and a porous drainage layer, creating a multi-functional system that provides both structural integrity and effective water management
2Reliability
If traditional corrugated liner is used, then installation is simple, but insulation performance against moisture, oil, and grease is insufficient
Solution Approach 1:
The composite multi-layer construction provides enhanced protection against moisture, oil, and grease while maintaining installation simplicity through the integrated design that requires no additional components or complex assembly procedures
3Ease of operation
If the liner surface is smooth, then installation is easy, but the surface provides no slip resistance
Solution Approach 1:
The liner features different surface characteristics on different faces: one face maintains a smooth configuration for easy installation, while the opposite face provides a textured, slip-resistant surface, allowing each surface to optimize its specific function
