Bed with automatically adjustable properties
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bed arrangements fail to provide personalized firmness adjustments based on individual user preferences and lying positions, leading to suboptimal comfort and sleep quality.
Innovation Solution
A bed arrangement with multiple zones of independently adjustable firmness and height, equipped with sensors to detect lying positions and control units to adjust firmness/height settings accordingly, allowing users to customize settings for different lying positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the bed provides fixed firmness settings determined at manufacturing, then the device structure remains simple and cost-effective, but it cannot accommodate different user preferences or body requirements
Solution Approach 1:
The patent implements dynamic firmness adjustment by replacing static elastic elements with actively controllable actuators (motors, cylinders, or inflatable elements) in each zone. These actuators can dynamically change the firmness level based on user preferences, body position detection, or therapeutic requirements, transforming a static system into a dynamically adaptable one.
Solution Approach 2:
The bed surface is divided into multiple independent zones, each with its own adjustable firmness control mechanism. This segmentation allows different parts of the bed to be adjusted independently to match different body regions' requirements, providing localized adaptability without requiring complete system redesign.
2Adaptability or versatility
If the bed uses uniform firmness across all zones, then the manufacturing process remains simple, but it cannot provide differentiated support for different body parts
Solution Approach 1:
The mattress is divided into multiple independent zones (e.g., head, shoulder, hip, leg regions), each equipped with its own firmness adjustment mechanism. This allows each zone to be manufactured and adjusted independently, facilitating modular assembly and customization during or after manufacturing.
Solution Approach 2:
Each zone can be configured with different firmness characteristics tailored to specific body part requirements. For example, softer zones can be provided for pressure-sensitive areas like shoulders and hips, while firmer zones support the head and legs, creating locally optimized support without complicating the overall manufacturing process.
3Adaptability or versatility
If the bed provides fixed height settings, then the structural design remains straightforward, but it cannot accommodate different user heights or sleeping positions
Solution Approach 1:
The bed incorporates dynamically adjustable height mechanisms using actuators (electric motors, pneumatic cylinders, or screw mechanisms) that can change the height of different zones independently. This allows the bed to adapt to various user heights and sleeping positions in real-time, transforming a static height configuration into a dynamic, user-adaptive system.

AI summary
A bed arrangement having adaptive properties is disclosed. The bed arrangement comprises a mattress comprising at least one zone having independently adjustable firmness and/or height, a drive unit arranged to adjust the firmness and/or height of said at least one zone and at least one sensor. The sensor(s) is adapted to measure a physical parameter which is relatable to a lying position used by a user. Further, a control unit is arranged to determine, based on input from said sensor(s), the present lying position of a user. The lying position is determinable to be one of a set of at least two predefined lying positions. Further, the control unit controls the drive unit to adjust the firmness and/or height of said zone(s) to preset firmness/height value(s) corresponding to the determined lying position. Hereby, an automatic adaption of the bed properties to various lying positions is obtained.
