Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for preventing pressure ulcers in bedridden patients are inadequate in effectively managing pressure, temperature, and moisture levels, leading to discomfort and the risk of bed sores.
Innovation Solution
A climate-controlled conditioner mat or topper member with fluid zones and non-fluid zones, featuring a spacer material to distribute fluids and maintain separation between layers, includes a fluid module for thermal conditioning and sensors for moisture detection, allowing for targeted delivery of heated or cooled air to reduce pressure and improve comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional mattress is used for bedridden patients, then the structure is simple and cost-effective, but it fails to effectively manage pressure, temperature, and moisture levels leading to pressure ulcers
Solution Approach 1:
The mattress is divided into multiple independent fluid chambers (first fluid chamber, second fluid chamber, third fluid chamber) that can be individually controlled. Each chamber can adjust pressure independently to prevent pressure ulcers on different body regions, transforming a single uniform surface into a segmented, dynamically adjustable system.
Solution Approach 2:
The mattress incorporates fluid modules with pumps and control systems that dynamically adjust the pressure, temperature, and moisture levels in each fluid chamber based on patient needs. This transforms a static mattress into a dynamic system that can respond to changing patient conditions in real-time.
2Adaptability or versatility
If fluid chambers are added to manage pressure and temperature, then climate control capability is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The fluid chambers serve multiple functions simultaneously: they provide pressure redistribution to prevent ulcers, temperature regulation through heated or cooled fluid circulation, and moisture management through controlled evaporation or absorption. This multi-functionality reduces the need for separate systems for each function.
Solution Approach 2:
The system controls pressure, temperature, and moisture levels by adjusting physical parameters of the fluid in the chambers (pressure, temperature, flow rate). By changing these parameters, the mattress can adapt to different patient conditions and therapeutic requirements.
3Ease of operation
If multiple fluid chambers with independent control are implemented, then pressure distribution and comfort are improved, but the control system complexity increases
Solution Approach 1:
The control system includes sensors that automatically detect patient position, pressure points, and environmental conditions, then autonomously adjust the fluid chamber parameters without requiring constant manual intervention. The system serves itself by monitoring and adjusting based on real-time feedback.
Solution Approach 2:
The mattress incorporates sensors that provide continuous feedback on patient condition and chamber performance to the control system. This feedback loop enables automatic adjustment of pressure, temperature, and moisture levels to maintain optimal conditions for preventing pressure ulcers.

AI summary
According to certain arrangements, a conditioner mat for use with a bed assembly includes an upper layer comprising a plurality of openings, a lower layer being substantially fluid impermeable, at least one interior chamber defined by the upper layer and the lower layer and a spacer material positioned within the interior chamber. In one embodiment, the spacer material is configured to maintain a shape of the interior chamber and to help with the passage of fluids within a portion of interior chamber. The conditioner mat can be configured to releasably secure to a top of a bed assembly.
