Removable Foam Spring Mattress Layout for Targeted Firmness Zones
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mattresses fail to provide customizable firmness to accommodate individual user preferences for comfort, as they often rely on fixed combinations of materials that cannot adapt to varying comfort requirements across different body areas.
Innovation Solution
A mattress system featuring interchangeable foam springs that can be arranged and attached to a foam panel within a containment facility, allowing users to select and place foam springs of varying firmness in specific locations to meet their comfort needs, using attachment devices like snaps, hook and loop fasteners, or glue.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed combinations of materials are used in mattresses, then manufacturing simplicity is maintained, but adaptability to different user comfort requirements deteriorates
Solution Approach 1:
The mattress is divided into multiple zones with different firmness levels, allowing each region to be optimized for specific body areas (head, shoulders, back, hips, legs). This segmentation enables customization without requiring a completely different mattress for each user preference.
Solution Approach 2:
Different foam densities and spring configurations are applied to specific locations within the mattress rather than using uniform materials throughout. Softer foams are placed in areas needing pressure relief while firmer sections provide structural support, creating localized comfort zones.
2Ease of operation
If interchangeable foam springs with attachment devices are used, then ease of operation for customization is improved, but device complexity increases
Solution Approach 1:
The mattress transitions from a static, fixed-structure design to a dynamic, reconfigurable system where foam springs can be moved, added, or removed based on user needs. This dynamic capability allows the mattress to adapt over time as user preferences or physical conditions change.
Solution Approach 2:
Attachment devices such as Velcro fasteners or interlocking mechanisms serve as intermediaries between the foam springs and the mattress structure, enabling easy connection and disconnection without requiring complex tools or permanent modifications.

AI summary
A method includes selecting an arrangement of foam springs, the arrangement that matches user-selected firmness requirements; attaching foam springs to a foam panel in a removable, replaceable manner; and inserting the foam springs and the foam panel into a containment facility. A mattress includes foam springs; a foam panel to which an arrangement of the foam springs is attached in a removable, replaceable manner; a containment facility within which the foam springs and the foam panel are disposed; and a side rail with indentations within which sides of at least some of the foam springs are disposed. The mattress may also include a fabric webbing, attached to the containment facility, within which some of the foam springs are disposed in a removable, replaceable manner; and an attachment device attaching together at least two of the foam springs.
