Electric motor driven adjustable mattress
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric motor driven adjustable mattress support apparatuses lack an aesthetically pleasing design and high comfort, and are inefficient in terms of storage and transport due to their bulkiness.
Innovation Solution
The integration of a compact electric motor driven adjustable support apparatus with pivot and folding axes, allowing the mattress to be adjusted between reclined and sitting positions, and featuring a folding mechanism that reduces its longitudinal extension for easier storage and transport, using Bowden cables and a shared electric motor for adjustable support parts, and spring elements on both sides for enhanced comfort and ventilation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional electric motor driven adjustable support apparatus is used, then the mattress can be adjusted between reclined and sitting positions, but the apparatus is bulky and requires specialized freight services for shipping
Solution Approach 1:
The support apparatus is divided into multiple support parts (first support part, second support part, third support part) that can be adjusted independently relative to each other. This segmentation allows the mattress to maintain adjustability functionality while enabling compact folding for reduced storage volume and easier transport.
Solution Approach 2:
The support parts are designed with pivot axes and folding mechanisms that allow dynamic adjustment between different positions (reclined, sitting) and dynamic folding for compact storage. The electric motor enables on-demand adjustment, transforming the apparatus from a static bulky structure to a dynamically adaptable system.
2Ease of operation
If multiple support parts are provided for adjustable positions, then user comfort is improved, but the device complexity increases
Solution Approach 1:
Multiple support parts (first, second, and third support parts) are merged into a single integrated mattress structure with shared electric motor control. This combining approach provides enhanced user comfort through multiple adjustment zones while avoiding the complexity of separate independent systems, as all parts are controlled by a single electric motor.
3Ease of operation
If spring elements are added on both sides of the mattress, then comfort and ventilation are enhanced, but the manufacturing complexity increases
Solution Approach 1:
Spring elements are strategically placed on both sides of the mattress at specific locations (first and second locations) rather than uniformly throughout. This local quality approach enhances comfort and ventilation where needed most while simplifying the manufacturing process compared to comprehensive spring integration across the entire mattress structure.
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
The solution provides improved comfort and aesthetics by allowing adjustable positions, and facilitates compact storage and transport, enabling standard shipping and easy handling without the need for specialized freight services.
Implementation Method 1
an electric motor driven adjustment apparatus (38) which has an output element that is in drive connection with the at least one electric motor
Implementation Method 2
The other end of the traction cable is secured to the neck support part (14) by means of a barrel-shaped fastening element (62). The jacket (50) of the Bowden cable is secured in a corresponding manner to the middle support part (8) and to the housing (44)
Implementation Method 3
an upper body support part (12), to one end of which a neck support part (14) is connected so as to be pivotable about a horizontal pivot axis (16)
Implementation Method 4
spring elements on both sides for enhanced comfort and ventilation

AI summary
An electric motor driven adjustable mattress has a shared casing in which at least one flat cushion element of a cushion structure and an electric motor driven adjustable support apparatus for supporting the cushion element are accommodated. The support apparatus has two support parts that are adjustable relative to one another, and that on their sides facing the cushion element are provided with spring elements for elastically resiliently supporting the cushion element. For adjusting the support parts relative to one another, an electric motor driven drive apparatus is accommodated in the shared casing.
