Mattress assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mattress assemblies are limited in size and lack adjustable safety features, requiring replacement of both the mattress and bed frame when a larger surface is needed, and fail to provide adequate safety for users like children and elderly individuals.
Innovation Solution
A mattress assembly with a supplement mattress featuring lateral and footboard extensions that can be rotated and adjusted using a tubular structure with fast-opening and closing means, providing a secure barrier and allowing the mattress surface to be expanded without replacing the bed frame, and equipped with clamps or girths for attachment to a main mattress.

Engineering Contradiction Analysis
1Area of moving object
If a larger mattress surface is needed, then the sleeping area is expanded, but the bed frame and upholstered bed base must be replaced
Solution Approach 1:
The mattress is divided into a main mattress and a supplement mattress that can be attached separately. The supplement mattress includes a main body and extensions that can be configured independently, allowing the sleeping surface to be expanded without replacing the entire bed frame or upholstered bed base.
Solution Approach 2:
The supplement mattress extensions are designed to be rotatable between different positions (horizontal plane for sleeping surface expansion, perpendicular position for safety barrier). This dynamic configuration allows the same structure to serve multiple functions: expanding sleeping area when needed and providing safety barriers when needed, without requiring permanent structural changes to the bed frame.
2Ease of manufacture
If standard-sized mattresses are used, then manufacturing and assembly are simplified, but the mattress surface cannot be expanded when needed
Solution Approach 1:
The mattress system is segmented into standardized main mattress and supplement mattress components. The supplement mattress can be manufactured using standard patterns and then configured in different arrangements (with extensions in various positions) to adapt to different space requirements and user needs, maintaining manufacturing simplicity while achieving versatility.
Solution Approach 2:
The supplement mattress is designed as a universal component that can be attached to standard mattresses and configured in multiple ways. The extensions can be rotated to provide either additional sleeping surface or safety barriers, making the same component adaptable to different situations without requiring custom manufacturing.
3Reliability
If conventional mattresses are used, then safety features are minimal, but users lack protection from falling to the ground
Solution Approach 1:
The supplement mattress extensions are designed to be rotatable between horizontal and perpendicular positions. When rotated to the perpendicular position, they form safety barriers that prevent users from falling off the bed. This dynamic feature allows the same structure to provide both sleeping surface expansion and fall protection, enhancing safety without adding separate complex safety structures.
Solution Approach 2:
The supplement mattress extensions serve multiple functions: they can be positioned horizontally to expand the sleeping surface or vertically to create safety barriers. This multi-functionality means that the same component provides both sleeping and safety functions, improving user protection without requiring additional dedicated safety devices that would increase device complexity.
4Ease of operation
If the supplement mattress is sewn at the factory, then assembly is simplified, but the mattress surface cannot be adjusted after purchase
Solution Approach 1:
The supplement mattress is segmented into the main body and rotatable extensions that are connected through mechanical means (hinges and fastening mechanisms) rather than permanent sewing. This allows the extensions to be detached and repositioned by the user after purchase, providing adaptability while maintaining relatively simple initial assembly through factory-prepared components.
Solution Approach 2:
The connection between the main body and extensions is designed to be mechanically adjustable rather than permanently fixed. The extensions can be rotated and repositioned by the user after purchase, allowing post-purchase adjustment of the mattress surface configuration while the factory assembly provides the basic structure ready for such adjustments.

AI summary
It comprises a main mattress (1) and a supplement mattress attached thereto. The supplement mattress (1) comprises a main body having two lateral extensions (2),a footboard extension (3), a headboard extension (17), and a tubular structure (5). Extensions can be rotated 90º or 180° together with the tubular structure (5). A fitted sheet (20) is also provided. The surface of the mattress assembly can be expanded and it provides a safety means for preventing the user from falling to the ground.
