Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bed frames that allow the sleep surface to incline do not provide sufficient adjustability, particularly in sections that support the abdomen, limiting the ability to achieve a neutral spinal posture for restful sleep and potentially contributing to health issues such as migraines, Alzheimer's, and sleep apnea.
Innovation Solution
A bed frame design featuring a lower and upper frame with pivotable sections, a scissor jack assembly, and hydraulic components that allow the bed frame to transition between parallel and acute angle configurations, enabling adjustable positioning to support the head, midsection, and feet independently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the bed frame allows the sleep surface to incline, then sleep comfort is improved, but adjustability of specific sections (such as abdomen support) is limited
Solution Approach 1:
The bed frame is divided into multiple independently movable sections: head section, midsection, and foot section. Each section can be adjusted independently through separate lifting assemblies, allowing the abdomen support section to move relative to other sections while maintaining overall incline functionality.
2Device complexity
If conventional bed frames use fixed sections, then structural simplicity is maintained, but the ability to achieve neutral spinal posture is limited
Solution Approach 1:
The bed frame transitions from a static structure to a dynamic one with multiple pivotable sections. The lifting assemblies enable each section to move between horizontal and inclined positions independently, allowing the bed to adapt to different spinal posture requirements while maintaining structural integrity through controlled mechanical movement.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enhances sleep comfort by allowing the sleeper's body to assume a neutral spinal posture, reducing stress on bones and joints, and potentially mitigating health issues associated with sleeping on a flat surface.
Implementation Method 1
The lifting assembly comprises a hydraulic cylinder and a piston that is movable relative to the hydraulic cylinder
Implementation Method 2
The scissor jack assembly comprises first and second links. The links each have a first end that is pivotably coupled to the lower frame and a second end that is pivotably coupled to the second section
Implementation Method 3
The first section is pivotable relative to the lower frame. The second section is pivotable relative to the first section and the third section

AI summary
A bed frame is provided that includes a lower frame and an upper frame having a first section, a second section and a third section. The second section is positioned between the first section and the third section. The first section is pivotable relative to the lower frame. The third section is fixed relative to the lower frame. The second section is pivotable relative to the first section and the third section. A lifting assembly includes a first end that is coupled to the lower frame and a second end that is coupled to the second section. The lifting assembly is configured to selectively move the second section toward and away from the lower frame.
