Segmented Covered Mattress for Bedsore Relief and Hygiene
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mattresses in care and medical settings face challenges such as difficulty in replacing or removing sections for pressure relief, leading to bedsores, and laborious cover fitting, which can result in soiling and bacterial contamination.
Innovation Solution
A mattress design with completely covered mattress sections using a permanent polyurethane cover and interlocking profile shapes for secure fastening, allowing removable sections without exposing the interior to soiling or bacterial risk.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a loose cover is fitted on the mattress body, then the mattress body is protected from soiling, but the fitting process is laborious and time-consuming
Solution Approach 1:
The cover is permanently fitted on the mattress body during manufacturing, eliminating the need for later fitting operations. This preliminary action resolves the contradiction by providing protection from soiling without requiring time-consuming fitting procedures during use or maintenance.
Solution Approach 2:
The permanently fitted cover design makes the mattress self-sufficient, requiring no additional cover fitting by users. The cover remains in place automatically, eliminating laborious fitting operations while maintaining continuous protection against soiling.
2Reliability
If the cover is permanently fitted on all mattress body sections, then the interior remains bacteria-free, but the structure becomes more complex
Solution Approach 1:
The mattress is segmented into multiple body sections, each with its own permanent cover. This segmentation allows the complex permanently fitted cover structure to be divided into manageable, identical modules, reducing overall complexity while maintaining reliable bacteria-free protection across all sections.

AI summary
A mattress (1) comprises a mattress body (2, 3) made of a resilient material, such as foam rubber, as well as a cover (12) permanently fitted on the mattress body (2, 3), such as a cover impermeable to moisture. In order to prevent bedsores, the mattress body has at least two mattress body sections (2, 3) adjoining one another, which mattress body sections (2, 3) have boundary surfaces (4, 5; 6, 7) facing one another, on which boundary surfaces (4, 5; 6, 7) a cover (12) is also permanently fitted.
