Innovation Solution
An electric motor driven adjustable mattress with a support apparatus that includes pivotable and foldable support parts connected via Bowden cables and a shared electric motor, allowing for adjustable positions from reclined to sitting and enabling compact folding for easy storage and transport, featuring a textile casing with an elastically resilient cushion element.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the support apparatus uses a complex mechanism with multiple support parts and electric motors for adjustment, then the adjustability and comfort are improved, but the device complexity increases and compactness deteriorates
Solution Approach 1:
The patent combines multiple support parts (head support part, back support part, thigh support part, calf support part) into a single integrated support apparatus that functions as one unified structure. This merging approach maintains the adjustability of individual parts while reducing overall structural complexity compared to having separate adjustable components.
Solution Approach 2:
The support apparatus is designed to perform multiple functions: supporting the head, back, thighs, and calves simultaneously; providing adjustment in different positions (reclined, sitting, folded); and enabling compact storage. This multi-functionality reduces the need for separate specialized components, thereby reducing overall device complexity.
2Ease of operation
If the support apparatus is designed with multiple adjustable support parts, then the comfort and support quality are improved, but the ease of storage and transport deteriorates due to reduced compactness
Solution Approach 1:
The support apparatus incorporates dynamic folding capability that allows it to transition from an extended comfortable position to a compact folded position. The head support part, back support part, thigh support part, and calf support part can be folded relative to each other, enabling compact storage while maintaining comfort during use.
Solution Approach 2:
The support parts are designed to nest within each other when folded, with the calf support part folding into the thigh support part, and the back support part folding into the head support part. This nesting arrangement minimizes the overall volume when stored while maintaining full adjustability during use.
3Device complexity
If the support apparatus uses a shared electric motor with Bowden cables for adjusting multiple support parts, then the device complexity is reduced, but the manufacturing precision and reliability may deteriorate
Solution Approach 1:
The patent uses Bowden cables as intermediary elements to transmit mechanical force from the single electric motor to multiple support parts. The Bowden cables act as flexible传动 elements that can accurately transmit the motor's rotational motion to the pivotable connections of each support part, maintaining adjustment precision while using a single motor.
Solution Approach 2:
The patent replaces multiple electric motors with a single electric motor combined with a mechanical transmission system using Bowden cables. This substitution reduces device complexity while maintaining the ability to precisely adjust each support part through the mechanical advantage and flexibility of the cable-pulley system.

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.
