Hospital Bed Rail Mechanism for Rotating Side Egress
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hospital and residential beds lack the flexibility to easily transition between lying and sitting positions, and navigating in confined spaces, posing challenges for patient care and mobility.
Innovation Solution
A bed with a rotating sleep surface, hydraulic braking system, spring-loaded steering, twin scissor mechanism, and adjustable tilt capabilities, allowing 360-degree rotation and side egress functions, enabling smooth transitions between lying, sitting, and standing positions, as well as easy maneuverability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional hospital bed is used, then the bed structure is simple and stable, but it lacks the flexibility to easily transition patients between lying, seated, and standing positions
Solution Approach 1:
The bed incorporates a rotating sleep surface that can dynamically change orientation from horizontal (lying position) to vertical (standing position) and intermediate angles (seated position). The scissor mechanism enables continuous adjustment of the sleep surface angle, transforming a static bed into a dynamic positioning system that adapts to different patient care needs
Solution Approach 2:
The bed system performs multiple functions: it serves as a traditional hospital bed for lying positions, transforms into a chair for seated positions, and enables standing positions for patient transfer. This multi-functionality eliminates the need for separate equipment and allows a single device to handle various patient positioning requirements
2Ease of operation
If the bed is equipped with rotation and lifting mechanisms, then patient transfer becomes easier, but the device becomes more complex and difficult to operate
Solution Approach 1:
The patent combines the rotation mechanism, lifting mechanism, and positioning controls into an integrated system. The scissor mechanism and rotating platform work together as a unified assembly, reducing the number of separate control systems and simplifying operation while maintaining full functionality for patient transfer
3Adaptability or versatility
If the sleep surface can rotate 360 degrees, then side egress chair functions are enabled, but the mechanism requires more space to operate
Solution Approach 1:
The bed utilizes the vertical dimension through the scissor lifting mechanism to enable side egress functions without requiring additional horizontal space. By lifting the rotating sleep surface vertically, the system creates chair-like positioning and side egress capabilities while maintaining a compact footprint suitable for confined hospital or home environments
