Mattress Spring Arm Layout for Adjustable Uniform Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spring bases for mattresses lack adjustable spring characteristics, leading to uneven support and compromised sleeping, sitting, or reclining comfort, as they are unable to adapt to varying loads.
Innovation Solution
The base spring design features spring arms guided downwards and then upwards around the outside of spring slats, with adjustable support elements and flexible connecting profiles, allowing for customizable spring properties and even distribution of force across the mattress surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If spring arms are guided directly upwards to accommodate the mattress, then the structure is simple, but the spring travel is limited and support is uneven
Solution Approach 1:
Instead of guiding spring arms directly upwards, the patent guides them downwards first between the spring slats, then curves them upwards around the outside of the slats. This inverted path configuration increases the effective spring travel distance while maintaining structural feasibility.
Solution Approach 2:
The spring arms transition from a simple vertical path to a three-dimensional curved path that extends both vertically and horizontally around the spring slats. This dimensional change allows for increased travel distance without proportionally increasing structural complexity.
2Adaptability or versatility
If spring characteristics are fixed, then manufacturing is simple, but the mattress cannot be evenly supported under varying loads
Solution Approach 1:
The patent introduces adjustable support elements that can modify the spring characteristics of individual spring arms. This dynamic capability allows the spring base to adapt to varying loads and user preferences, transforming a static structure into an adaptable system.
Solution Approach 2:
The spring base is divided into multiple independent spring arms, each with its own adjustable support element. This segmentation allows individual customization of spring characteristics for different regions, enabling localized adaptation without redesigning the entire system.
3Ease of operation
If support points are close to the mattress underside, then structure is compact, but support distribution is uneven
Solution Approach 1:
Instead of positioning support points close to the mattress, the spring arms are routed around the outside of the spring slats, effectively moving the support points farther away. This inverted positioning approach distributes the support force more evenly across the mattress surface.
4Adaptability or versatility
If female connectors have fixed orientation, then assembly is simple, but spring properties cannot be individualized
Solution Approach 1:
The female connectors are designed to be rotatable about their longitudinal axes, allowing their orientation to be adjusted. This dynamic positioning capability enables customization of spring properties for each connector while maintaining a relatively simple assembly process.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enhances the spring characteristics, providing more uniform support and adjustable comfort, allowing for personalized optimization of the mattress's support behavior based on load distribution and user preferences.
Implementation Method 1
The base spring is made of an elastic material, preferably plastic
Implementation Method 2
the force that acts from the mattress on the support plates and the spring arms is transferred to the pair of slats

AI summary
Supporting spring systems for sleeping, reclining or seating furniture must have spring characteristics that provide good sleeping, lying and/or seating comfort. In known supporting spring systems this is only achieved by relatively high design expenditure. The invention aims to create a simple and flexible supporting spring system which nevertheless ensures high sleeping, lying and/or sitting comfort. For this purpose, supporting elements (13, 50, 60, 70, 80) for connecting two female connectors (10) of a female connector pair (11) are provided. The supporting elements (13, 50, 60, 70, 80) comprise spring arms (15, 72) that are guided from beneath the female connectors (10) of the female connector pairs (11) up around the outside of the female connector pair (11).
