Adjustable Slatted Base Layout for Ergonomic Support Zones
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slatted bases lack the ability to adjust the mutual distance between adjacent slats, limiting the definition of specific zones on the lying surface for ergonomic alignment.
Innovation Solution
The slatted base features adjustable and fixable bearing elements that support slats with vertically oriented lifting drives, allowing for horizontal displacement and adjustment of slat distances, enabling the definition of individual zones with specific horizontal distances between slats.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the slatted base uses fixed bearing elements for slats, then the structure is simple and stable, but the ability to define specific zones on the lying surface is limited
Solution Approach 1:
The bearing elements are made adjustable in the horizontal longitudinal direction, transforming a static fixed structure into a dynamic adjustable one. This allows the mutual horizontal distances between slats to be modified to define specific zones such as lordosis and pelvic zones, while maintaining structural stability through fixable positions.
Solution Approach 2:
The bearing elements are divided into individually adjustable units, each capable of independent horizontal displacement. This segmentation allows different regions of the lying surface to be configured with different slat distances, enabling zone-specific ergonomic alignment without requiring complete structural redesign.
2Adaptability or versatility
If the bearing elements are made adjustable horizontally, then specific zones can be defined with different slat distances, but the device complexity increases
Solution Approach 1:
The bearing elements are designed with multi-functionality, serving both as support structures for the slats and as adjustable positioning mechanisms. By integrating the horizontal displacement capability into the existing bearing element design, the patent avoids adding separate adjustment mechanisms, thereby limiting the increase in device complexity.

Function Achieved in This Case
This solution expands the usability of the slatted base by allowing for the definition of specific zones across the lying surface, such as the lordosis and pelvic zones, with adjustable horizontal distances between slats, enhancing ergonomic alignment and user comfort.
Implementation Method 1
a deformation sensor (20) in the form of a spring body (20) which supports the slat (12) and can be vertically displaced
Implementation Method 2
a vertically oriented lifting drive (27, 49), which vertically displaces a mounting body (21) on which the spring body (20) is supported

AI summary
A slatted base having a frame and a measuring device for detecting the deformation of a lying surface under the load of a person lying thereon, wherein the deformation is carried out by detecting the vertical deflection of slats, which are held on both sides in a slatted base with their free ends in a mounting body, on which the displaceable end of a vertically oriented lifting drive engages, which is supported with respect to a bottom-side base frame, wherein the mutual horizontal distances between the slats is adjustable and fixable.
