Adjustable bed
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional beds are fixed in size and require professional installation, lacking adjustability for user comfort and ease of assembly, and do not allow for size changes.
Innovation Solution
An adjustable bed system with power-driven lifting assemblies, including side rails, lifting actuators, and a controller, allowing for adjustable back and leg positions, and the ability to change bed size by modifying the length of the upper and lower rails.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional fixed-size beds are used, then manufacturing and installation are simple, but adaptability and user comfort are poor
Solution Approach 1:
The bed is divided into modular components including side rails, upper rails, lower rails, and lifting assemblies that can be independently assembled and configured. The side rails are further segmented with detachable connections at their ends, allowing the bed frame to be assembled in sections and configured in different sizes by connecting different numbers of modules.
Solution Approach 2:
The bed structure transitions from a fixed configuration to a dynamic, adjustable configuration. The lifting assemblies with actuators enable the bed to change its configuration between different sleeping positions and sizes, allowing the same bed structure to adapt to different user needs and comfort requirements.
2Ease of operation
If conventional beds require professional installation, then structural stability is ensured, but assembly efficiency and ease of operation are reduced
Solution Approach 1:
The bed is designed as a modular assembly with standardized connection interfaces between components. The side rails have detachable connections at their ends that can be easily coupled with upper and lower rails, allowing users to assemble the bed in sections without requiring professional installation, while maintaining structural integrity through standardized connection mechanisms.
Solution Approach 2:
The bed incorporates self-aligning and self-securing features in its modular connection system. The detachable connections between rails are designed to be easily engaged and disengaged by users without specialized tools or skills, enabling self-service assembly while ensuring reliable structural stability through the standardized connection design.
3Adaptability or versatility
If fixed-position lifting mechanisms are used, then structural simplicity is maintained, but adaptability for different positions is limited
Solution Approach 1:
The lifting assemblies are designed as multi-functional units that can perform multiple operations. Each lifting assembly includes a lifting mechanism and an actuator that can adjust the position of bed sections to various angles and configurations, allowing the same mechanism to serve multiple positioning functions rather than requiring separate fixed-position mechanisms for each location.
Solution Approach 2:
The lifting mechanism transitions from a fixed-position design to a dynamic positioning system. The actuators enable continuous adjustment of the lifting arms to various angles and positions, allowing the bed to achieve multiple configurations and sleeping positions using a single adjustable mechanism rather than multiple fixed mechanisms.

AI summary
An adjustable bed system includes a pair of side rails transversely spaced, longitudinally aligned and arranged parallel to each other; and a pair of lifting assemblies attached respectively to the pair of side rails for operably adjusting positions of at least one part of a bed. Each lifting assembly comprises a back lifting arm and a leg lifting mechanism; a bracket; and a back lifting actuator and a leg lifting actuator received in the bracket. Each actuator includes an activation member and a motor member engaged with the activation member for driving the activation member. The activation member of the back lifting actuator is engaged with the back lifting arm for operably adjusting the back lifting arm at desired back positions. The activation member of the leg lifting actuator is engaged to the leg lifting mechanism for operably adjusting the leg lifting mechanism at desired leg positions.
