Segmented Mattress Fire Barriers With Replaceable Comfort Layers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The one-sided mattress design reduces the lifespan of mattresses, leading to increased waste and maintenance costs, as users cannot access or replace the interior cushioning materials, and the conventional fire barrier design is inefficient due to its universal application, not accounting for disparate flammability characteristics of different foam types.
Innovation Solution
A mattress design featuring a detachable upper comfort layer assembly and a plurality of fire barriers, allowing users to replace worn components and tailor fire barrier selection to specific regions based on flammability, reducing waste and enhancing fire safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a one-sided mattress design is used to eliminate the need for flipping, then ease of operation is improved, but the lifespan of the mattress is reduced and waste increases
Solution Approach 1:
The mattress is divided into two functional segments: a permanent base layer with support core and fire barrier, and a removable upper comfort layer assembly. This segmentation allows the comfort layer to be replaced when worn, extending the overall mattress lifespan while maintaining the one-sided design's ease of use.
Solution Approach 2:
The upper comfort layer assembly is designed to be removable and replaceable. When the comfort layer becomes worn or loses its supportive properties, it can be discarded and replaced with a fresh layer, thereby recovering the value of the mattress base and extending the product's useful life.
2Object-affected harmful factors
If conventional universal fire barrier design is used, then fire safety is provided, but fire barrier efficiency is reduced due to not accounting for disparate flammability characteristics
Solution Approach 1:
Different fire barrier materials are selected for different regions of the mattress based on the specific flammability characteristics of the foam layers in those regions. High-flammability latex foam areas receive more robust fire barrier protection, while lower-risk areas use lighter barrier materials, optimizing both safety and efficiency.
Solution Approach 2:
The fire barrier design varies parameters such as material type, thickness, and composition across different regions of the mattress to match the flammability profile of underlying foam layers, rather than applying a uniform barrier throughout.
3Ease of repair
If detachable upper comfort layer assembly is implemented, then ease of repair is improved, but device complexity increases
Solution Approach 1:
The mattress is segmented into a permanent base layer and a removable upper comfort layer assembly, allowing the comfort layer to be independently replaced without affecting the base structure.
Solution Approach 2:
The upper comfort layer assembly is nested within an outer cover assembly that can be detached. This nested structure allows the comfort layer to be accessed and replaced through the outer cover, simplifying the repair process while managing structural complexity.

AI summary
A mattress wherein a plurality of independent yarn based fire barrier fabrics encases a plurality of distinct and unattached interior core structures. The plurality of interior core structures include at least a detached and internally flippable upper comfort layer assembly with a plurality of non-homogeneous foams or filling materials encased in a yarn-based fire barrier fabric and a lower, interiorly disposed support core structure with resilient filling materials encased in a yarn-based fire barrier fabric and a fabric cover. The detachable and internally flippable upper comfort layer assembly may be contained in a user accessible compartment that is fashioned into an outer cover assembly.
