Massaging Bed Base Slat Motion for Bedsore Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anti-decubitus bed solutions are inadequate in preventing the formation of bedsores, as they often rely on pneumatic mattresses that fail to effectively detach the patient from the bed surface, leading to pressure changes and friction-related injuries, and are typically designed for post-sore prevention rather than proactive measures.
Innovation Solution
A bed base with movable portions that allow for adjustable inclinations and a massaging mechanism using articulated shafts and cams to create a sinusoidal wave motion, reducing pressure points and improving blood circulation without causing temperature increases.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If pneumatic mattresses are used to create pressure changes, then some decompression effect is achieved, but the patient cannot be effectively detached from the bed surface and friction-related injuries occur
Solution Approach 1:
The bed base is divided into multiple movable portions that can be independently lifted and lowered to create dynamic position changes. This dynamic movement effectively detaches the patient from the bed surface, eliminating both pressure-related bedsores and friction injuries by continuously changing the contact zones between the patient body and support surface.
Solution Approach 2:
The bed base is segmented into multiple independent movable portions (first portion, second portion, third portion, fourth portion) that can be controlled separately. This segmentation allows selective lifting of different body zones (head, chest, legs) to achieve comprehensive pressure relief and patient detachment without causing friction in any single zone.
2Object-affected harmful factors
If only pneumatic mattresses with inflatable zones are used, then pressure changes are created, but effective patient detachment from the bed surface cannot be ensured
Solution Approach 1:
The invention employs dynamic lifting and lowering of multiple bed base portions to create effective patient detachment. The movable portions can be raised to lift the patient body away from the support surface, ensuring reliable detachment that pneumatic mattresses alone cannot achieve.
Solution Approach 2:
The massaging means act as an intermediary mechanism between the bed base and the patient. By providing rolling or pressing actions on the patient's body, the massaging means enhance the detachment effect and ensure reliable pressure relief in addition to the lifting action of the movable portions.
3Adaptability or versatility
If movable portions are added to allow adjustable inclinations, then patient positioning flexibility is improved, but device complexity increases
Solution Approach 1:
The bed base is divided into multiple independently controllable portions (first, second, third, and fourth portions) that can be lifted or lowered separately. This segmentation provides versatile patient positioning capabilities, allowing the head, chest, and legs to be positioned at different inclinations while maintaining a manageable structural complexity through modular design.

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 solution effectively prevents bedsores by allowing continuous movement and massaging action, reducing pressure on at-risk zones and enhancing blood circulation, while being designed for proactive prevention rather than post-sore treatment.
Implementation Method 1
The slats are movable vertically by deflection by means of at least one rotary shaft provided with cam means for coupling with the slats
