Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional flooring materials for ships lack the ability to realize various appearances while being eco-friendly and safe, as they often compromise on flame retardancy due to high smoke density and poisonous gas emission during fires.
Innovation Solution
A flame retardant tile for ships comprising a base layer made of a biodegradable resin composition, including polylactic acid (PLA) resin, inorganic flame retardants, and fillers, combined with a printed layer for aesthetics and a transparent layer containing a phosphorus flame retardant for enhanced safety and reduced smoke and gas emissions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a decorative tile made of PVC material is used to realize various appearances and reduce cost, then appearance versatility and manufacturing cost are improved, but smoke density and poisonous gas emission increase significantly during combustion
Solution Approach 1:
The patent uses a composite material structure consisting of a base layer made from biodegradable resin (PLA) combined with inorganic flame retardants and fillers. This composite approach allows the material to achieve both aesthetic versatility through the printed layer and fire safety through the biodegradable base layer that produces minimal smoke and toxic gases during combustion.
Solution Approach 2:
The patent changes the chemical composition parameters of the flooring material by replacing conventional PVC with biodegradable PLA resin. This parameter change fundamentally alters the combustion characteristics, reducing smoke density and poisonous gas emission while maintaining the ability to achieve various appearances through the printed decorative layer.
2Reliability
If conventional flooring materials with mineral wool base material are used to achieve thermal and sound insulation, then insulation performance and production cost are improved, but appearance versatility is limited
Solution Approach 1:
The patent segments the flooring material into distinct functional layers: a base layer for thermal and sound insulation properties, a printed layer for aesthetic appearance, and a transparent protective layer. This segmentation allows each layer to optimize its specific function while collectively providing both insulation performance and appearance versatility.
Solution Approach 2:
The base layer made from biodegradable resin with inorganic flame retardants and fillers serves multiple functions simultaneously: it provides thermal insulation, sound insulation, flame retardancy, and structural support. This multi-functionality replaces the need for separate mineral wool base material while adding appearance versatility through the integrated printed layer.
3Reliability
If rubber material is applied to achieve superior flame retardancy, then fire safety is improved, but manufacturing cost increases and appearance versatility is limited
Solution Approach 1:
The patent changes the material composition by using biodegradable PLA resin combined with inorganic flame retardants instead of expensive rubber materials. This parameter change maintains flame retardancy through the chemical properties of the biodegradable resin and inorganic additives while significantly reducing manufacturing cost and enabling appearance versatility through the printed layer.
Solution Approach 2:
The patent creates a composite material system where biodegradable PLA resin serves as the base material and inorganic flame retardants are incorporated to achieve flame retardancy. This composite approach replaces expensive rubber materials while maintaining fire safety performance and reducing cost, with the added benefit of appearance versatility through the printed decorative layer.
