Adjustable Bed with Segmented Platform Lifting for Enhanced Comfort
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional adjustable beds have limited adjustability, which restricts users' ability to achieve maximum comfort by not allowing sufficient customization of body positions.
Innovation Solution
An adjustable bed system with a frame structure, back and foot lifting assemblies, and a lumbar support mechanism that allows for adjustable angles and positions of the head, back, and foot platforms, utilizing motor-driven actuators and mechanisms to pivotally move these platforms and provide lumbar support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional adjustable beds are used, then basic head and foot elevation is provided, but adjustability is very limited
Solution Approach 1:
The bed is divided into multiple independently adjustable platforms (head platform, back platform, foot platform) that can be controlled separately. Each platform has its own lifting assembly, allowing granular adjustment of different body zones to achieve maximum comfort while maintaining manageable complexity through modular design
Solution Approach 2:
The bed system transitions from static or simple adjustable positions to dynamically adjustable platforms with multiple degrees of freedom. The back platform can be independently tilted relative to the head platform, and each platform can be elevated to different heights, creating a dynamic system that adapts to various sleeping positions
2Ease of operation
If multiple platforms with adjustable angles are implemented, then user comfort is enhanced, but structural complexity increases
Solution Approach 1:
Multiple lifting functions are combined into integrated lifting assemblies. The back lifting assembly simultaneously supports and positions both the head platform and back platform, while the foot lifting assembly handles the foot platform. This merging reduces the number of separate mechanisms needed while maintaining full adjustability
Solution Approach 2:
The system adds vertical elevation adjustment as an additional dimension to the traditional horizontal positioning. Each platform can be adjusted not only in angle but also in height independently, creating a two-dimensional adjustment space (angle + height) that enhances comfort without requiring overly complex mechanisms

AI summary
An adjustable bed includes a frame structure having a back frame and a foot frame; a back lifting assembly comprising a back lifting bracket pivotally connected to the back frame, and a back lifting actuator pivotally connected between the back lifting bracket and the back frame for operably driving the back lifting bracket to pivotally move in an upward rotating direction or a downward rotating direction relative to the back frame; and a plurality of platforms comprising at least a head platform and a back platform hinged to the head platform supported by the back lifting bracket such that angles and positions of the head platform and the back platform are adjustable in accordance with the back lifting bracket.
