Sleeping mattress
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In difficult environments like prisons or hospitals, existing sleeping box springs pose risks of injury from reinforced bed frames and allow individuals to hide objects within the mattress and bed base interstices.
Innovation Solution
A sleeping box spring design featuring a base with folded edges and internal fixing means, covered with foam and a perforated cover, reinforced with elements to prevent injury and object concealment, utilizing welded fixing means and thermo-welded angles to secure the structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a reinforced metal bed frame is used to withstand harsh environments, then the durability and strength of the bed base is improved, but the risk of injury to individuals (particularly to shins) increases
Solution Approach 1:
A foam layer is introduced as an intermediary between the reinforced metal bed frame and the user. This foam mediator maintains the structural strength of the metal frame while providing a soft, safe surface that prevents injury to shins and other body parts.
Solution Approach 2:
A flexible cover is used to enclose the foam and base structure. This flexible shell provides a soft exterior that eliminates the harmful rigid edges of the metal frame, while the internal structure maintains its strength for durability.
2Strength
If a reinforced metal bed frame with gaps is used, then the durability is improved, but the ability to hide objects (such as lighters or razor blades) in the gaps increases
Solution Approach 1:
A flexible cover is stretched over the entire bed base structure, creating a smooth continuous surface that eliminates gaps where objects could be hidden. The cover maintains the underlying rigid structure's durability while providing a safe, gap-free surface.
Solution Approach 2:
The solution moves from a two-dimensional frame structure with gaps to a three-dimensional enclosed structure covered by a flexible shell. This dimensional change eliminates the gap problem while preserving structural integrity.
3Ease of operation
If the bed base structure is made accessible, then ease of operation and maintenance is improved, but the risk of injury and object hiding increases
Solution Approach 1:
The flexible cover can be removed or opened for maintenance access to the internal structure, then resecured to restore the safe enclosed configuration. This allows maintenance while maintaining safety during normal use.
Solution Approach 2:
The cover is designed to be dynamically adjustable - accessible for maintenance when needed, but securely closed during normal use to prevent injury and object hiding. The structure transitions between accessible and enclosed states as required.

AI summary
The invention relates to a bed base characterized in that it comprises: a base having a folded rim having an inner face having a plurality of fixing means; a foam adapted to cover the base and the outer face of each folded rim; a cover adapted to cover the foam, said cover having a perimeter having perforations, said perforations being adapted to cooperate with the fixing means so that the perimeter covers the inner face of the folded rim; a plurality of reinforcing elements arranged against the perimeter so that said perimeter is included between said inner face of the folded rim and said reinforcing element.
