Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional flame-resistant materials used in commercial transportation lack aesthetic appeal and comfort, failing to provide a visually pleasing and comfortable insulation solution while maintaining flame-proof properties.
Innovation Solution
A dual- or multi-layer insulation system comprising a UL 94 V-0 compliant, self-extinguishing, thermally and acoustically viable system with a contact layer, substrate layer, and foam layer, bonded using an adhesive and activator, and processed with specific tooling and press implanting pressure, heat, and time, which can include perforated vinyl or cloth and a fire-retardant PVC alloy sheet, enhancing both thermal and acoustical properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional flame-resistant materials (hard fiber insulation panels, cellulose fiber, foam products with foil layer) are used, then flame resistance is achieved, but aesthetic appeal and comfort are compromised
Solution Approach 1:
The patent employs a composite material structure consisting of multiple layers: a foam core layer (providing flame resistance and thermal insulation), a fabric layer (providing aesthetic appeal and comfort), and a foil layer (providing additional flame reflection and resistance). This composite structure integrates the advantages of different materials to simultaneously achieve flame resistance and aesthetic appeal, resolving the technical contradiction between reliability and ease of manufacture.
2Ease of manufacture
If multi-layer composite structure is implemented, then aesthetic appeal and comfort are improved, but device complexity increases
Solution Approach 1:
The insulation material is segmented into distinct functional layers: a foam core layer for flame resistance and thermal insulation, a fabric layer for aesthetic appeal and comfort, and a foil layer for flame reflection. Each layer is independently manufactured and then bonded together, allowing for simplified production of individual layers while achieving complex overall functionality when assembled.
Solution Approach 2:
The multi-layer structure is designed so that each layer serves multiple functions. For example, the foam core layer provides both flame resistance and thermal insulation, while the fabric layer provides both aesthetic appeal and structural support. This multi-functionality reduces the need for additional specialized components, thereby managing complexity.
3Reliability
If flame-resistant materials are used, then safety is improved, but thermal and acoustical performance may be compromised
Solution Approach 1:
The composite structure combines a foam core layer (excellent thermal insulation properties), a foil layer (reflects thermal radiation and enhances flame resistance), and a fabric layer (provides acoustical absorption). This combination ensures that safety requirements are met while maintaining or enhancing thermal and acoustical performance, as each material contributes its strengths to the overall system.
