Multifunctional Nursing Mattress with Automated Pneumatic Posture Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional air beds are inadequate in preventing bedsores as they cannot adjust the user's posture and increase caregiver workload, especially when patients need to change positions, leading to discomfort and inefficiency.
Innovation Solution
A multifunctional nursing mattress with inflatable bags for back lifting, side overturning, and foot lifting, controlled by an inflation device and a control unit that adjusts air pressure based on user weight and selected posture mode, allowing for improved posture adjustment and bedsore prevention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional air bed is used for bedsore prevention, then massage effect is achieved through inflation and deflation, but the user's posture cannot be adjusted and caregiver workload increases
Solution Approach 1:
The air bed system automatically adjusts user posture through automated inflation and deflation of positioning air bags controlled by a control unit, eliminating the need for manual caregiver intervention. The system monitors user position and autonomously performs posture adjustments, allowing the device to serve itself rather than requiring external human operation.
Solution Approach 2:
The patent replaces manual mechanical posture adjustment with an automated pneumatic control system. The control unit electronically manages the inflation and deflation sequences of multiple air bags to achieve posture changes, substituting the traditional mechanical manual adjustment method with an automated control mechanism.
2Reliability
If traditional air bed is used for bedsore prevention, then massage effect is achieved, but posture adjustment capability is lacking
Solution Approach 1:
The air bed system integrates multiple functions including massage, posture adjustment, positioning, and bedsore prevention into a single device. The control unit coordinates multiple air bags to perform both massage cycles and posture adjustment sequences, making the device versatile rather than single-purpose.
Solution Approach 2:
The system dynamically adjusts user posture by controlling the inflation and deflation of positioning air bags in specific sequences. The air bags are inflated and deflated at different times to achieve various posture positions, creating dynamic adaptability rather than static positioning.
3Adaptability or versatility
If multiple inflatable bags are added for posture adjustment, then posture adjustment capability is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple functions (massage, posture adjustment, positioning) into a single integrated air bed system controlled by one control unit. The control unit manages all air bags centrally, and the mattress structure integrates multiple air bags working together rather than as separate devices.
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
The mattress effectively prevents bedsores by allowing users to adjust their posture and reduces caregiver workload through automated inflation and deflation, enhancing comfort and safety.
Implementation Method 1
an inflation device to inflate and deflate a plurality of inflation inflatable bags, a back lifting inflatable bag, a left-side overturning inflatable bag, a right-side overturning inflatable bag and a foot lifting inflatable bag
