Adjustable Bed Friction Mount for Mattress Slip Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Adjustable beds face challenges in maintaining mattress position and alignment during articulation due to insufficient friction between the mattress and the bed foundation, leading to slippage and misalignment.
Innovation Solution
Incorporating friction-enhancing materials, such as thermoplastic elastomers, on the mattress support surface and the mattress itself, which increase the coefficient of static friction, ensuring the mattress remains aligned and in contact with the bed foundation across various articulated positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If friction-enhancing materials are added to the mattress support surface, then the coefficient of static friction increases and mattress slippage is prevented, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent changes the friction parameter of the mattress support surface by incorporating friction-enhancing materials with specific coefficients of static friction (μs ≥ 0.5). This modifies the physical property of the contact surface to increase grip on the mattress without altering the fundamental structure of the adjustable bed foundation.
Solution Approach 2:
The patent uses composite materials consisting of friction-enhancing layers (such as thermoplastic elastomers, thermoset elastomers, or fabric materials like non-woven fabric) applied to the mattress support surface. These composite structures combine the structural integrity of the rigid support surface with the high-friction properties of the overlay material.
2Stability of the object's composition
If friction-enhancing materials are used, then mattress alignment is maintained during articulation, but manufacturing cost and material complexity increase
Solution Approach 1:
The patent modifies the friction parameter of the contact surface to maintain mattress alignment during articulation movements. By selecting materials with specific friction coefficients, the system ensures the mattress remains properly positioned without requiring complex mechanical alignment mechanisms.
Solution Approach 2:
The friction-enhancing materials are applied specifically to the mattress support surface where contact with the mattress occurs. This localized application of enhanced friction properties targets the specific problem area without requiring modification of the entire bed structure.

AI summary
The disclosure generally relates to an adjustable bed, in particular incorporating a friction mattress mount. In various embodiments, an adjustable bed foundation can include friction-enhancing materials mounted on a deck support surface. The friction-enhancing materials maintain the mattress in a desired position and alignment with respect to the adjustable bed foundation, in particular when adjustable bed foundation is adjusted between various articulated positions (e.g., flat, inclined, and/or declined).
