Segmented Air-Bladder Bedding for Firmness and Climate Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bedding systems fail to provide adequate adjustability in firmness and climate control to accommodate individual user preferences and changing needs over time, leading to discomfort and disrupted sleep due to limited resolution in air bladder arrangements and inadequate temperature regulation.
Innovation Solution
The development of active comfort controlled bedding systems that integrate a plurality of air bladders between cradle foam layers, allowing for independent pressure adjustment and the use of a flow distribution member and air blower assembly for climate control, enabling variable firmness and temperature regulation across different regions of the mattress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional air bladders are used in adjustable air beds, then the structure is simple, but the resolution of adjustability is too low to accommodate individual user preferences and body variations
Solution Approach 1:
The mattress is divided into multiple independently controllable air chambers arranged in a grid pattern, with each chamber capable of independent pressure adjustment. This segmentation allows precise localization of support in different body regions (head, torso, legs, shoulders) while maintaining overall system manageability through modular zoning.
Solution Approach 2:
Different regions of the mattress are equipped with different numbers and configurations of air chambers based on local support requirements. High-support areas like the lumbar region have denser chamber arrangements, while less critical areas have fewer chambers, optimizing adjustability resolution where needed without unnecessarily increasing overall complexity.
2Adaptability or versatility
If multiple foam layers are used to achieve different firmness levels, then manufacturing is simplified, but the ability to accommodate changing user needs over time is limited
Solution Approach 1:
The mattress transitions from static foam layers to dynamic air-filled chambers that can be adjusted in real-time. Each air chamber's pressure can be modified independently to adapt to changing user needs, weight distribution, and sleep preferences throughout the night or over time, providing continuous adaptability rather than fixed firmness levels.
Solution Approach 2:
The same air chamber structure serves multiple functions: providing support, adjusting firmness, and accommodating different sleep positions and body types. This multi-functionality eliminates the need for separate foam layers for different firmness levels, as the air chambers can be configured to provide various support characteristics through pressure adjustment alone.
3Measurement precision
If a single air bladder spans the width of the bed, then device complexity is low, but it cannot resolve the complexities and variances between individual users' sizes, weights, and sleep patterns
Solution Approach 1:
Instead of single spanning bladders, the system uses multiple smaller air chambers arranged in rows and columns. This segmentation allows each chamber to be independently sized and positioned to match anatomical landmarks and pressure points, providing precise support customization for different body sizes and sleep patterns while maintaining a systematic, manageable structure.
4Temperature
If conventional bedding systems are used, then manufacturing is simple, but they fail to provide adequate temperature regulation, causing discomfort and disrupted sleep
Solution Approach 1:
The air chambers serve dual functions: mechanical support and thermal regulation. By adjusting air pressure and volume, the system can modify both firmness and heat dissipation characteristics. Inflated chambers provide cooling through air circulation and contact with cooler surfaces, while deflated chambers allow closer contact with warmer mattress layers, enabling passive temperature regulation without separate heating/cooling systems.

AI summary
Active comfort controlled bedding systems (10) and processes include an air blower assembly for variable climate control. The air blower assembly generally includes a unidirectional air blower (300) configured to flow air to and from a mattress surface overlaying the bucket assembly.
