Adjustable Mattress with Hinged Foot Region for Backrest Formation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adjustable beds do not efficiently convert into a supported seating area with a backrest, lacking a practical and comfortable mechanism for adjusting the bed's position.
Innovation Solution
The adjustable mattress features a top and bottom mattress layer with an adjustable region that can tilt from 0 to 180 degrees, forming a backrest, and includes a frame and actuator for movement and locking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an adjustable frame with a flexible mattress is used to allow head and foot portions to be raised or lowered independently, then the occupant can be positioned in more upright positions with elevated feet, but the bed cannot efficiently convert into a supported seating area with a backrest
Solution Approach 1:
The mattress is divided into multiple independent adjustable regions including a head portion, middle portion, and foot portion, each capable of independent adjustment. This segmentation allows the mattress to be configured into various positions including a supported seating area with backrest, which cannot be achieved with traditional single-unit adjustable frames.
Solution Approach 2:
The mattress incorporates dynamic adjustment capabilities where each region can be independently positioned at different angles. The adjustable regions can be raised or lowered to create a supported seating configuration with a backrest formed by the head and middle portions, providing both adaptability and practical operation.
2Adaptability or versatility
If a multifunction bed is converted from hospital bed to wheelchair form, then the bed size can be reduced and converted between forms, but the conversion is complex with many structural changes and safety mechanisms
Solution Approach 1:
The mattress uses dynamic adjustment of independent regions to achieve form conversion. By raising or lowering specific adjustable regions, the mattress can transition between bed and wheelchair forms without requiring complex structural changes or multiple safety mechanisms, simplifying the conversion process while maintaining versatility.
Solution Approach 2:
The conversion between bed and wheelchair forms is achieved by changing the angular parameters of adjustable regions. Each region can be positioned at specific angles to create the desired form, eliminating the need for complex mechanical reconfiguration and reducing device complexity.
3Ease of operation
If traditional adjustable beds are used, then the head and foot portions can be adjusted independently, but the mattress lacks a mechanism to form a supported backrest for seating positions
Solution Approach 1:
The mattress is segmented into multiple adjustable regions including head, middle, and foot portions that can be independently adjusted. This segmentation enables the formation of a supported backrest by positioning the head and middle regions at appropriate angles, while maintaining the ease of independent adjustment of head and foot portions.
Solution Approach 2:
The adjustable regions serve multiple functions: they can be used for standard head and foot adjustment, and simultaneously form a supported backrest for seating positions. This multi-functionality allows the mattress to provide both independent head/foot adjustment and backrest formation without requiring separate mechanisms.
