Bed Base with Dual-Drive Massaging Slats to Prevent Bedsores
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anti-decubitus beds are ineffective in preventing the formation of bedsores and often cause additional issues due to limited pressure distribution and friction between the patient and the bed surface, especially when portions of the mattress are lifted or bent.
Innovation Solution
A bed base with movable portions that can be inclined relative to each other, equipped with actuators and massaging mechanisms to create a continuous movement and reduce pressure points, allowing for various user positions and preventing bedsores through controlled rotation and vertical movement of slats.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stress or pressure
If pneumatic mattresses are used to create pressure changes in some zones, then pressure distribution is improved, but the patient moves on the bed causing friction between sheets and patient's body which can cause injuries
Solution Approach 1:
The bed base employs continuously movable slats that can independently adjust their position and angle, creating dynamic pressure redistribution without the patient's body moving on the bed. This eliminates friction between sheets and patient's body while maintaining improved pressure distribution.
Solution Approach 2:
The bed base is divided into multiple independent slats that can move separately, allowing localized pressure adjustment in different zones without causing overall bed movement. This segmentation enables pressure relief in specific areas while keeping the patient stable on the bed.
2Stress or pressure
If portions of the mattress are lifted to change pressure distribution, then pressure points are reduced, but the massaging action becomes ineffective in lifted configurations
Solution Approach 1:
The massaging means are integrated with the movable slats and automatically adapt their action to the slats' position. Whether slats are horizontal or inclined, the massaging elements continue to exert effective pressure through the mattress, ensuring consistent massaging effectiveness across all bed configurations.
Solution Approach 2:
The bed base system performs multiple functions simultaneously: it provides pressure redistribution through slat movement and delivers massaging action through integrated massaging means. Both functions remain effective regardless of the slats' angular position, making the system universally effective in all configurations.
3Stress or pressure
If pneumatic mattresses are used for pressure changes, then some zones are decompressed, but the solution is only effective when bedsores have already arisen rather than preventing them
Solution Approach 1:
The continuously moving slats and massaging means provide ongoing pressure redistribution and stimulation before bedsores can develop. This preliminary and continuous action prevents the formation of pressure ulcers rather than treating them after they arise, enhancing the reliability of bedsore prevention.
Solution Approach 2:
The slats move continuously rather than in discrete inflation/deflation cycles, providing constant pressure redistribution and massaging action. This continuous useful action effectively prevents bedsore formation by maintaining ongoing decompression and circulation stimulation, making the system reliable for prevention rather than just treatment.
