Anti-bedsore Bed with Motorized Support Rods
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical beds are inefficient in preventing bedsores and require frequent re-positioning of patients, which strains caregivers and complicates cleaning and disinfection processes.
Innovation Solution
An anti-bedsore bed design featuring adjustable and motor-driven supporting rods and sliding blocks that uplift the user's body, allowing for easy re-positioning and conversion into a wheelchair or caregiver bed, with integrated foot and head rests that can be elevated or retracted for cleaning and hygiene purposes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If frequent manual re-positioning is performed to prevent bedsores, then patient skin health is improved, but caregiver physical strain increases
Solution Approach 1:
The bed system performs automatic re-positioning of the patient without requiring manual intervention by caregivers. The control unit autonomously activates power units to adjust the positions of supporting rods and sliding blocks, enabling the patient to be re-positioned independently, thus eliminating caregiver physical strain while maintaining bedsore prevention effectiveness
Solution Approach 2:
Manual mechanical re-positioning by caregivers is replaced with an automated mechanical system comprising power units, supporting rods, and sliding blocks. The control unit coordinates these mechanical components to automatically adjust patient positioning, substituting human physical effort with automated mechanical action to prevent bedsores
2Object-affected harmful factors
If the bed structure is made complex to enable re-positioning functions, then patient care quality is improved, but device complexity increases
Solution Approach 1:
The bed structure is divided into multiple independent functional modules: supporting rods, sliding blocks, power units, and control units. Each module performs a specific function (positioning, support, actuation, or coordination), allowing the complex re-positioning task to be broken down into manageable segments that work together systematically
Solution Approach 2:
The bed structure incorporates movable and adjustable components including supporting rods that can extend/retract, sliding blocks that move along rails, and power units that provide dynamic actuation. These dynamic elements enable the bed to adapt its configuration automatically, achieving effective re-positioning through coordinated movement of multiple dynamic parts rather than a static complex structure
3Adaptability or versatility
If the bed is designed with multiple functions (anti-bedsore, wheelchair, caregiver bed), then versatility is improved, but device complexity increases
Solution Approach 1:
The bed system is designed with a modular and reconfigurable structure that can serve multiple functions: anti-bedsore mode with automatic re-positioning, wheelchair mode for patient mobility, and caregiver bed mode for attendant use. The same fundamental components (frames, supporting elements, power units) are utilized across different operational modes, allowing one system to perform multiple roles without requiring entirely separate structures for each function

AI summary
An anti-bedsore bed may comprise a bed unit, a first bed body, and a second bed body. The bed unit has a first mattress, and a bottom portion is coupled on a bottom surface thereof. Moreover, the bottom portion comprises a plurality of first supporting units at positions corresponding to a user's upper back, middle portion of back and lower back, and each of the first supporting units has a first sliding block moveably mounted on the bottom portion. Each of the first sliding blocks has a first supporting rod, and an abutting unit is pivotally connected to an upper end of the first supporting rod. Each of first power units secured on a bottom surface of the first sliding block is engaged with the first supporting rod while each of second power units secured on the bottom portion is engaged with the first sliding block.
