Mattress air supply
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current air supply systems for inflatable devices, such as therapy and patient transfer mattresses, require separate equipment for each mattress, leading to clutter and inefficiency, as they need to manage different air pressure and flow rate demands simultaneously.
Innovation Solution
An air supply system with an air compressing device and multiple pressure valves that can supply air to multiple inflatable devices at different pressure and flow rate ranges, allowing for simultaneous operation with independent control of air pressure and flow rate for each device, using configurations like multi-speed compressors, dual compressors, or single compressors with pressure valves to manage the air distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate air supplies are used for each mattress, then each mattress can meet its specific air pressure and flow rate demands, but the equipment clutter and system complexity increase
Solution Approach 1:
The patent combines multiple separate air supply systems into a single integrated air supply unit that can serve multiple mattresses simultaneously. This consolidation reduces equipment clutter while maintaining the ability to meet specific air pressure and flow rate demands for each mattress through internal distribution mechanisms and control valves.
Solution Approach 2:
The integrated air supply unit is designed with multi-functionality to handle different air pressure and flow rate requirements for various types of mattresses (therapy mattresses, patient transfer mattresses, etc.). It incorporates multiple outlets and adjustable controls that allow each mattress to receive appropriately tailored air supply from the same device.
2Device complexity
If a single air supply serves multiple mattresses, then equipment clutter is reduced, but the ability to meet different air pressure and flow rate demands simultaneously becomes difficult
Solution Approach 1:
The air supply system implements local quality by providing customized air supply characteristics to different outlets based on the specific requirements of each connected mattress. Each outlet can be independently adjusted to deliver the appropriate air pressure and flow rate, allowing the system to adapt to diverse mattress types from the same centralized unit.
Solution Approach 2:
The system incorporates dynamic control capabilities through adjustable valves and controls at each outlet, allowing real-time modification of air pressure and flow rate settings. This enables the air supply unit to adapt to changing requirements of different mattresses or the same mattress under different operating conditions.
3Temperature
If air is supplied to therapy mattress with controlled leakage holes, then the mattress remains cool and comfortable, but air loss occurs requiring continuous air supply
Solution Approach 1:
The air supply system is designed to provide continuous air supply to the therapy mattress, compensating for the controlled air loss through leakage holes. This continuous supply maintains the mattress inflation and cooling function, ensuring the therapeutic benefits are sustained over extended periods without interruption or deflation.
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 system effectively manages air distribution to multiple inflatable devices, maintaining consistent pressure and flow rates, reducing clutter and improving operational efficiency by allowing for tailored air supply to each device's specific needs, while minimizing disruptions between different operational modes.
Implementation Method 1
The air supply includes an air compressing device, and at least two pressure valves
Implementation Method 2
The air supply is operable to introduce air from a pressure valve to a first inflatable device at a first pressure

AI summary
An air supply supplies air to multiple different inflatable devices. The air supply includes an air compressing device, and at least two pressure valves. The air supply operates to introduce air from the first pressure valve to a first inflatable device at a first pressure that is within a first air pressure range. The air supply also operates to introduce air, on demand, from the second pressure valve to a second inflatable device at a second pressure within a second air pressure range while continuing to supply air to the first inflatable device at a pressure within the first air pressure range. The second pressure and/or the second pressure range is different from the first pressure and/or the first pressure range.
