Solution Overview
Problem
Existing bed rest designs with slats are complex, expensive, and prone to mechanical friction and maintenance issues, failing to provide optimal support for the vertebral column and leading to discomfort and early wear.
Innovation Solution
A bed rest with flexible, elastically yielding slats connected through a simple mechanical system using pulleys and sliding guides, allowing active reaction to body weight and anatomy, ensuring orthopedic support and easy maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a plurality of mechanical elements (pistons, springs, connection elements) are used to support the vertebral column, then the orthopedic support function is improved, but the device complexity and manufacturing cost increase significantly
Solution Approach 1:
The patent extracts and eliminates the complex mechanical elements (pistons, springs, connection elements) from the bed rest structure, replacing them with a simplified slat system that directly provides orthopedic support through elastic deformation of the slats themselves, thereby reducing device complexity while maintaining the support function
Solution Approach 2:
The patent employs flexible slats that can elastically deform under body weight to provide orthopedic support, replacing rigid mechanical elements with flexible structural components that achieve the same support function through material elasticity rather than complex mechanical mechanisms
2Reliability
If multiple mechanical components are placed inside the bed frame to provide support, then the orthopedic support capability is improved, but the ease of maintenance and accessibility deteriorates
Solution Approach 1:
The patent segments the support function into individual slats that can independently deform and be independently replaced, allowing maintenance of specific slats without disassembling the entire bed frame structure, thereby improving ease of repair while maintaining orthopedic support capability
Solution Approach 2:
The patent removes mechanical components from inside the bed frame and replaces them with slats that form the visible surface structure, making all support elements accessible from the outside for easy inspection and replacement without frame disassembly
3Adaptability or versatility
If a high number of mechanical elements are provided to react to body pressure, then the adaptability to body anatomy is improved, but the risk of loss and maintenance difficulty increases
Solution Approach 1:
The patent changes the operational parameter from discrete mechanical element movement to continuous elastic deformation of slats, allowing the slats to naturally adapt to varying body pressures through material properties rather than through complex mechanical adjustments, thereby reducing the number of elements needed
4Reliability
If pistons and springs are used to offset depressions and support the vertebral column, then the orthopedic support is improved, but mechanical friction increases leading to early wearing
Solution Approach 1:
The patent replaces the mechanical piston-spring system with a direct slat elastic deformation system, eliminating mechanical friction between moving parts and replacing it with internal material elasticity, thereby reducing wear and extending service life while maintaining orthopedic support function
