Inflatable air mattress system with detection techniques
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air mattress systems lack effective detection techniques for user presence, motion, and sleep position, which limits their ability to adjust firmness and provide personalized comfort and monitoring features.
Innovation Solution
The air mattress system incorporates a pressure transducer and central controller that measure air pressure changes to detect user presence, motion, and sleep position, using algorithms to determine rolling averages and gross pressure changes, and can correlate this data with biometric signals to assess sleep quality and adjust firmness and temperature accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If pressure transducers and detection algorithms are added to the air mattress system, then user presence, motion, and sleep position detection capabilities are improved, but device complexity increases
Solution Approach 1:
The patent combines multiple detection functions (presence detection, motion detection, sleep position detection) into a single integrated system using pressure transducers embedded in the mattress. The central controller processes all detection data through unified algorithms, merging what would otherwise be separate detection systems into one cohesive unit, thereby improving measurement precision without proportionally increasing overall system complexity.
Solution Approach 2:
The pressure transducer system serves multiple functions simultaneously: detecting user presence, monitoring motion, and determining sleep position. This multi-functionality allows the system to improve various measurement capabilities using a single detection mechanism, avoiding the need for separate specialized sensors for each function and thus limiting the increase in device complexity.
2Ease of operation
If real-time detection and automatic adjustment features are implemented, then user comfort and sleep quality monitoring are improved, but energy consumption increases
Solution Approach 1:
The system implements periodic detection and adjustment cycles rather than continuous operation. The central controller executes detection algorithms at intervals, processing pressure transducer data periodically to determine user presence, motion, and sleep position. This periodic action provides automatic adjustment capabilities while significantly reducing energy consumption compared to continuous real-time monitoring.
Solution Approach 2:
The system automatically adjusts firmness and temperature based on detected user state without requiring manual intervention. The central controller autonomously processes detection data and triggers appropriate adjustments, enabling ease of operation through self-service functionality while managing energy consumption by only activating adjustment mechanisms when detection algorithms identify the need for change.
