Solution Overview

Problem

Conventional mattresses with transversely aligned spring strands fail to provide consistent suspension comfort across different body positions and areas, leading to unpredictable spring effects when combined with slatted frames.

Innovation Solution

Aligning the chambers for spring strands in the longitudinal direction of the mattress allows for a natural body alignment and consistent spring support, eliminating the need for differentiated zones and enhancing the synergy between spring strands and slatted frames.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If spring strands are aligned transversely to the longitudinal direction of the mattress, then it is possible to provide zones with different springing comfort that follow one another in the longitudinal direction, but the suspension comfort is inconsistent across different body positions and areas

Engineering Contradiction:
Improvespringing comfort zonesVSAvoidsuspension comfort consistency
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent inverts the conventional transverse alignment of spring strands and instead aligns them in the longitudinal direction of the mattress. This inversion allows the spring strands to run parallel to the spine of a user, providing consistent suspension comfort across all body positions while still enabling differentiated support zones through variations in spring properties along the longitudinal axis.

Inventive Principle:
Principle #13The other way round (Inversion)

2Ease of manufacture

If spring strands are aligned transversely, then the mattress structure follows conventional design, but the spring effect becomes unpredictable when combined with slatted frames

Engineering Contradiction:
Improveconventional designVSAvoidspring effect predictability
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The patent changes the orientation parameter of the spring strands from transverse to longitudinal alignment. This parameter change creates a predictable synergistic effect when combined with slatted frames, as the longitudinal alignment ensures uniform distribution of forces and eliminates the unpredictable spring effects that occur with transverse alignment.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If spring strands are aligned longitudinally, then consistent suspension comfort is achieved across all body positions, but the conventional transverse zoning approach is abandoned

Engineering Contradiction:
Improvesuspension comfort consistencyVSAvoidspringing comfort zones
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The longitudinal alignment of spring strands creates a universal support system that functions effectively for all body positions (side, prone, and supine) without requiring different configurations. The spring strands serve multiple functions simultaneously: providing consistent suspension comfort, supporting spinal alignment, and enabling differentiated zone support through longitudinal variations in spring properties.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Function Achieved in This Case

This configuration provides improved suspension comfort by evenly cushioning body weight distribution, ensuring optimal lying comfort regardless of position and eliminating the need for separate head and foot area adjustments, while achieving a synergistic spring effect with slatted frames.

AI summary

The mattress (1) has suspension spring structures that are formed from several interconnected spring elements. A longitudinal extension of the suspension spring structure exceeds a transverse extension. A base portion (2) is provided with chambers (5) for retaining the suspension spring structures. The chambers are aligned in the longitudinal extension along longitudinal direction (6) of the mattress. An independent claim is included for a mattress system.
