Smart response technology mattress
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smart response technology mattresses lack enhanced user comfort due to inadequate dynamic pressure relief and adaptability to different sleeping positions and weights.
Innovation Solution
The mattresses incorporate a sub-core assembly with a pre-stressed polyurethane foam base layer, a self-adjusting smart response unit featuring fluid support cells with reforming elements, and a manifold system with intake and exhaust valves that dynamically open and close in response to weight loads, combined with an elastic conformance layer and viscoelastic foam layers for improved support and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional mattress structure is used, then the structure is simple and easy to manufacture, but the dynamic pressure relief and adaptability to different sleeping positions are insufficient
Solution Approach 1:
The mattress is divided into multiple independent fluid support cells arranged in a grid pattern, each capable of independent volume adjustment. This segmentation allows different regions to adapt to different body parts and sleeping positions independently, resolving the contradiction between adaptability and structural simplicity.
Solution Approach 2:
The fluid support cells incorporate dynamic response mechanisms with intake and exhaust valves that automatically adjust cell volume in real-time based on applied weight and pressure. This dynamic adaptation enables the mattress to respond to different sleeping positions and weights without requiring complex external control systems.
2Ease of operation
If fluid support cells with dynamic adjustment are added, then the pressure relief and comfort are improved, but the device complexity increases
Solution Approach 1:
The fluid support cells are equipped with self-regulating intake and exhaust valves that automatically respond to weight and pressure changes without external control. The system serves itself by using the applied load to trigger the appropriate valve responses, eliminating the need for complex control systems while maintaining high user comfort.
Solution Approach 2:
The patent uses pneumatic fluid support cells connected through manifold systems to provide dynamic support. The pneumatic mechanism allows for smooth, continuous adjustment of support levels through valve-controlled air flow, improving comfort while keeping the mechanical structure relatively simple compared to electric or mechanical actuation systems.
3Ease of operation
If multiple foam layers with different properties are added, then the comfort and support are enhanced, but the manufacturing complexity increases
Solution Approach 1:
The mattress incorporates multiple foam layers with different densities and viscoelastic properties (including memory foam and latex) combined with the fluid support cell system. This composite structure provides differentiated comfort and support zones that adapt to various body parts and sleeping positions, enhancing user comfort while using established foam manufacturing techniques.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration provides enhanced user comfort by dynamically adjusting to the user's movements and weight distribution, offering optimal pressure relief and support regardless of sleeping position or size.
Implementation Method 1
The reforming element is capable of providing a reforming force to the interior surface of the envelope, to return the envelope to its original unloaded form
Implementation Method 2
intake and exhaust valves fluidly coupled to the manifold conduit configured to dynamically open and close in response to a weight load
Implementation Method 3
a viscoelastic foam layer overlaying the sub-core having a convoluted top surface and a planar bottom surface
