Motorized Bed Slat Bottom With Adjustable Stiffness Zones
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motorized beds lack the ability to dynamically adjust stiffness and comfort according to individual sleeper preferences, leading to suboptimal sleep quality due to uniform elasticity across the mattress surface.
Innovation Solution
A motorized bed with an adjustable slat bottom system using sleeve members and a stiffening strip with adhesive glue coating, allowing for zone-by-zone elasticity adjustment and enhanced stiffness at pressure-bearing points, combined with modular spring assemblies and a pressure-profiled stiffening strip to optimize mattress support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a uniform slat bottom structure is used, then the manufacturing is simple, but the sleep comfort is insufficient due to inability to provide zone-specific support
Solution Approach 1:
The slat bottom is divided into multiple independent slats that can be individually adjusted. Each slat can be modified separately by adding or removing stiffening strips at specific locations, enabling zone-specific support customization without redesigning the entire structure.
Solution Approach 2:
Stiffening strips are selectively applied to specific slats at specific locations based on the sleeper's pressure profile. This creates local variations in stiffness where needed (under high-pressure areas) while maintaining flexibility in other areas, achieving adaptability without uniform complexity throughout the entire structure.
2Strength
If the slat bottom is made very stiff, then the support is strong, but the comfort is reduced due to lack of elasticity
Solution Approach 1:
The slat bottom system transitions from a fixed stiffness structure to a dynamically adjustable one. Users can modify the elasticity by adding or removing stiffening strips from individual slats, allowing the support strength to be optimized for different sleepers and conditions while maintaining the ability to adjust when needs change.
Solution Approach 2:
The stiffness parameter of the slat bottom is made variable through the selective application of stiffening strips. By changing the number, position, and distribution of these strips, the overall elasticity and support characteristics of the slat bottom can be continuously adjusted to match different sleeper requirements.
3Reliability
If adhesive glue is applied to the stiffening strip, then the strip securely locks the slats, but the manufacturing complexity increases
Solution Approach 1:
The adhesive application process is designed to be self-service rather than requiring complex industrial assembly equipment. The stiffening strips come pre-coated with adhesive that activates through simple pressure application during assembly, allowing reliable bonding without sophisticated manufacturing infrastructure.

AI summary
The invention relates to a motorized bed, stiffening part for a motorized bed and method of forming a motorized bed. The motorized bed (10) comprises a self-supporting frame and, in connection with it, a slat bottom (13) movable with a motor (Ml, M2), and on top of which a mattress may be adapted. In the slat bottom (13) there is a second slat (13bl, 13b2,...) attached to the slat (13al, 13a2,...) by means of a sleeve member (14), whereby by changing the position of the sleeve member (14) in the slat the combined elasticity of the slats may be adjusted. The motorized bed (10) further comprises a strip (21), that is, a stiffening part which is detachably attached to the top surface of the slats, whereby the strip (21) locks the slats to each other and adds to the stiffness of the slat bottom (13) at the spot in question.
