Air Pocket Module with Segmented Pressure Control for Mattress Comfort
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional spring mattresses transmit vibrations and have fixed elasticity, while air mattresses cannot adjust pressure for different body parts or health conditions, and are prone to depression under user weight.
Innovation Solution
An air pocket module with inflatable air pockets and a bottom plate, allowing pressure adjustment through a controller and pressure sensor system, arranged in rows and columns to form sections for specific body areas, with features like inclined connections and reinforcement to prevent depression.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If air mattress uses fixed air pressure at manufacturing, then structure is simple, but pressure adjustment for different body parts is impossible
Solution Approach 1:
The air mattress is divided into multiple independent air pockets (first, second, third air pockets) corresponding to different body parts (head/shoulder, waist, legs). Each air pocket can be independently inflated or deflated through separate communication holes and valves, allowing localized pressure adjustment without affecting other regions. This segmentation enables customized pressure distribution while maintaining a relatively simple overall structure.
Solution Approach 2:
The air mattress transitions from a fixed pressure system to a dynamic adjustable system. Communication holes allow air to flow between chambers, and valves enable users to control inflation/deflation in real-time. This dynamic capability allows the mattress to adapt to different body types and sleeping positions, resolving the contradiction between simplicity and adaptability.
2Strength
If spring mattress uses coil springs, then cushioning is provided, but vibrations are transmitted to surrounding areas
Solution Approach 1:
The invention removes the coil spring component entirely and replaces it with an air-filled chamber system. The air pockets provide cushioning through air compression rather than mechanical spring action, eliminating the vibration transmission problem inherent in coil springs while maintaining the desired cushioning effect.
3Ease of operation
If air mattress upper portion is open, then air flow is good, but depression under user weight occurs
Solution Approach 1:
The air pocket upper portions are sealed with flexible upper surfaces that can deform under user weight but maintain structural integrity. These flexible membranes allow the air pockets to conform to body contours while preventing collapse, ensuring both proper air flow distribution and reliable structural support during use.
4Area of stationary object
If air pockets are arranged in rows and columns, then body area coverage is improved, but manufacturing complexity increases
Solution Approach 1:
The air mattress is constructed as a modular grid of air pockets arranged in rows and columns, with each pocket being a standardized unit. This segmentation allows for systematic manufacturing and assembly, where identical or similar components can be produced in batches and then configured in different patterns to cover various body areas, balancing coverage improvement with manufacturing efficiency.

AI summary
An air mattress includes an air pocket unit including an air pocket module, a body portion into which the air pocket unit is inserted and fixed, a controller mounted at the body portion and controlling the air pocket unit, and a pressure sensor unit measuring pressure of the air pocket unit. The air pocket module includes multiple air pockets each having a hollow portion formed therein and configured to inflate due to air inflow or to deflate due to air outflow, and a bottom plate coupled to lower sides of the air pockets and configured to block the hollow portion of each of the air pockets.
