Expandable Mattress Assembly With Rotating Safety Extensions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mattress assemblies are limited in size, requiring replacement of both the mattress and bed frame when a larger surface is needed, and lack safety barriers for vulnerable individuals, such as children and the elderly.
Innovation Solution
A mattress assembly with a supplement mattress featuring lateral and footboard extensions that can be rotated to expand the surface, incorporating a tubular structure with fast-opening devices and adjustable sections, providing a safety barrier by forming a horizontal or perpendicular plane, and including clamps for attachment to a main mattress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If a larger mattress surface is needed, then the sleeping area is improved, but the mattress and bed frame must be replaced which increases cost and complexity
Solution Approach 1:
The mattress is divided into a main body and separate extendable extensions (lateral extensions and footboard extension). These extensions can be added to increase the mattress surface area without replacing the entire mattress or bed frame, thus resolving the contradiction between increasing area and reducing complexity.
Solution Approach 2:
The extensions are designed to be rotatable relative to the main body, allowing dynamic adjustment between a horizontal configuration (increasing sleeping area) and a vertical/configuration (providing safety barrier). This dynamic capability enables the mattress to adapt to different needs without physical replacement.
2Reliability
If safety barriers are added to prevent falls, then user safety is improved, but the mattress structure becomes more complex
Solution Approach 1:
The extensions serve dual functions: they can be positioned horizontally to increase sleeping area or rotated vertically to provide safety barriers. This dynamic multi-functionality provides safety protection without requiring separate dedicated safety structures, thus improving reliability while minimizing additional complexity.
Solution Approach 2:
The same extendable components serve multiple purposes: surface expansion and safety barrier formation. This multi-functionality means that adding safety features does not require separate dedicated structures, thereby improving safety while keeping the overall structure relatively simple.
3Area of moving object
If the mattress surface is expanded, then the sleeping capacity is improved, but the bed frame and canapé must also be replaced
Solution Approach 1:
By segmenting the mattress into a main body and detachable extensions, the design allows surface expansion independent of the bed frame. The extensions attach to the existing mattress and can be configured as needed, maintaining compatibility with standard bed frames and canapés while increasing sleeping capacity.
4Ease of manufacture
If standard size mattresses are used, then manufacturing is simplified, but adaptability to different space requirements is reduced
Solution Approach 1:
The mattress is manufactured as a main body with separate extension components that can be attached as needed. This segmentation allows the main body to be produced using standard processes while the extensions provide customizable size adjustments, thus maintaining ease of manufacture for the core component while achieving adaptability through modular addition.
Solution Approach 2:
The rotatable extensions provide dynamic size adjustment capability. The mattress can be configured in different effective sizes by adjusting the extensions, allowing a single standard-manufactured base to adapt to various space requirements and user needs.

AI summary
A main mattress and a supplement mattress attached thereto. The supplement mattress may have a main body having two lateral extensions, a footboard extension, a headboard extension, and a tubular structure. Extensions can be rotated 90° or 180° together with the tubular structure. A fitted sheet may also be provided. The surface of the mattress assembly can be expanded and it may provide a safety barrier for preventing the user from falling to the ground.
