Inflatable Mattress Gyroscope Pressure Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current bed-rest systems with inflatable mattresses struggle to automatically and continuously adjust internal pressure in response to minimal changes in backrest inclination, leading to discomfort and increased risk of bedsores, as they are often dependent on the bed's structure and require manual or incomplete automatic pressure modifications.
Innovation Solution
Incorporating a gyroscope within the mattress's upper part, connected to electronic pressure regulation means, to detect and respond to slight changes in inclination, allowing for continuous adaptation of internal pressure in the cells supporting the seat area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If mechanical sensors mounted on the bed structure are used to detect changes in inclination, then automatic pressure modification can be achieved, but the mattress becomes dependent on the bed structure and requires costly technical compatibility measures
Solution Approach 1:
The patent extracts the inclination detection function from the bed structure and relocates it directly to the mattress by integrating a gyroscope sensor within the mattress itself. This eliminates the dependency on bed structure sensors and resolves the technical compatibility issues while maintaining automatic pressure modification capability
Solution Approach 2:
The gyroscope sensor acts as an intermediary device that directly measures the mattress's inclination angle without requiring connection to the bed's motorization or structure. This intermediary approach enables automatic pressure control while avoiding complex technical compatibility requirements
2Extent of automation
If pressure is modified by passing stages through threshold detection, then automatic pressure control is achieved, but comfort drops and bedsores risk increases during pressure transition
Solution Approach 1:
The patent transitions from static threshold-based pressure control to dynamic continuous pressure control. The gyroscope continuously monitors inclination angle and the control unit continuously adjusts pressure accordingly, eliminating the discomfort and bedsore risk associated with staged pressure changes
Solution Approach 2:
The system implements continuous feedback control where the gyroscope constantly provides inclination data to the control unit, which continuously adjusts pressure in real-time. This continuous feedback loop ensures pressure is always appropriate for the current position, preventing bedsore formation during transitions
3Extent of automation
If the mattress is connected to the bed's motorization for position detection, then automatic pressure adjustment can be performed, but the system becomes limited by the number of existing mattresses and beds
Solution Approach 1:
The patent extracts the position detection capability from the bed system and embeds it directly in the mattress through the gyroscope. This makes the mattress self-sufficient for position detection and eliminates the need for connection to specific bed motorizations, greatly enhancing compatibility with existing beds
Solution Approach 2:
The mattress becomes self-sufficient by integrating the gyroscope sensor directly into its structure. It independently detects its own inclination without requiring external bed system components, making it universally compatible with existing beds while maintaining automatic pressure adjustment
