Hinged Corner Mattress Sections for Easy Fitted Sheet Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mattress systems face challenges in efficiently and safely positioning, retaining, and removing fitted sheets, often requiring cumbersome and time-consuming processes.
Innovation Solution
A corner mattress system with isosceles right triangle corner sections and hinge assemblies allows for easy positioning and retention of fitted sheets by pivoting the corner sections, using retainer assemblies with pins and straps to secure the sheet in place.

Engineering Contradiction Analysis
1Ease of operation
If traditional mattress systems are used, then the mattress structure is simple, but the process of positioning, retaining, and removing fitted sheets is cumbersome and time-consuming
Solution Approach 1:
The mattress is divided into a central section and four separate corner sections that can be independently manipulated. The corner sections are segmented from the central section through hinge assemblies, allowing them to be pivoted independently to facilitate sheet placement and removal without moving the entire mattress.
Solution Approach 2:
The corner sections are made dynamically movable through hinge assemblies that allow pivoting between a horizontal position (for normal use) and an upwardly pivoted position (for sheet manipulation). This dynamic capability enables easy sheet placement and removal while maintaining structural integrity when closed.
2Ease of operation
If corner sections are made movable to facilitate sheet removal, then sheet removal becomes easy, but the structural stability of the mattress may be compromised
Solution Approach 1:
The hinge assemblies enable the corner sections to pivot dynamically between fixed positions (horizontal for use, upward for sheet removal) rather than being continuously movable. This provides stability during normal use while enabling easy sheet removal when needed.
Solution Approach 2:
By segmenting the mattress into independently movable corner sections connected through hinges, the design allows localized movement without compromising the overall structural stability of the entire mattress assembly.

AI summary
A mattress has a central section. The central section has horizontal upper and lower surfaces. The central section has parallel first and second side faces. The central section has parallel first and second end faces. The side and end faces are vertically oriented. The side and end faces each have a rectangular configuration. The central section has four corner faces located between the end and side faces. The mattress has four similarly configured corner sections. Each corner section has a hypotenuse face positionable in facing contact with an associated corner face of the central section during use. Each corner section has two similarly configured leg faces positionable as planar extensions of contiguous side and end faces.
