Solution Overview

Problem

Existing multi-zone mattresses do not effectively integrate multiple sections of varying firmness profiles across different layers to provide optimal support and comfort, as they lack a systematic construction method that ensures consistent firmness differences between zones.

Innovation Solution

A multi-zone mattress design comprising a top layer, intermediate layer, and bottom layer with distinct sections of different firmness profiles, where each layer includes proximal, middle, and distal sections separated by interior and exterior sections, forming discrete zones with varying firmness profiles to provide cooperative support and comfort.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple sections of varying firmness profiles are integrated across different layers, then support and comfort are enhanced, but construction complexity increases

Engineering Contradiction:
Improvefirmness profile variationVSAvoidconstruction complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The mattress is divided into multiple discrete zones (head, torso, leg regions) with distinct firmness profiles. Each zone is constructed with specific combinations of coil spring densities and foam layer configurations, allowing independent optimization of support characteristics for different body regions while maintaining systematic construction through standardized zone modules.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different sections of the mattress incorporate varying densities of coil springs and different types of foam materials (memory foam, polyfoam, latex) in specific locations. The head region uses higher coil density for support, the torso zone uses medium density with memory foam for pressure relief, and the leg region uses lower density for comfort, creating locally optimized firmness profiles throughout the mattress structure.

Inventive Principle:
Principle #3Local quality

2Adaptability or versatility

If discrete zones with different firmness are created, then support optimization is improved, but manufacturing precision requirements increase

Engineering Contradiction:
Improvezone firmness differentiationVSAvoidzone boundary precision
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The mattress construction uses clearly defined zone boundaries separated by border fabrics and distinct coil spring sections. Each zone is manufactured as a discrete module with standardized dimensions, making it easier to maintain precise boundaries during assembly. The use of separate pocketed coil sections for each zone ensures clear demarcation without requiring complex blending transitions.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The coil spring sections and foam layers are pre-configured into zone-specific modules before final mattress assembly. Pocketed coils are pre-sorted by density and pre-assembled into zone-appropriate sections, and foam layers are pre-cut to match zone boundaries. This preliminary preparation ensures precise zone differentiation is achieved during manufacturing without requiring complex real-time adjustments.

Inventive Principle:
Principle #10Preliminary action
