Solution Overview

Problem

Current air mattress systems lack advanced sensing capabilities to automatically adjust firmness, temperature, and position based on user presence, sleep state, and biometric signals, limiting personalized comfort and sleep monitoring.

Innovation Solution

An air bed system with integrated pressure and temperature sensors, a control box, and a remote control that uses a processor to adjust air chamber pressure and temperature, along with an articulation controller to change bed positions, enabling real-time adjustments and monitoring of user biometrics and sleep patterns.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If automatic sensing capabilities are added to adjust firmness, temperature, and position, then personalized comfort and sleep monitoring are improved, but device complexity increases

Engineering Contradiction:
Improvepersonalized comfort adjustmentVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The bed system is divided into multiple independently controllable zones with separate air chambers, temperature control elements, and sensor arrays. Each zone can be adjusted individually based on local sensing data, allowing personalized comfort without requiring a completely complex centralized system for the entire bed.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The control system integrates multiple functions into a single platform that handles pressure sensing, temperature regulation, firmness adjustment, and position control. This multi-functional approach reduces overall system complexity by consolidating control logic and communication protocols rather than using separate dedicated systems for each function.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Measurement precision

If multiple sensors and control mechanisms are integrated, then sleep monitoring accuracy is improved, but manufacturing complexity increases

Engineering Contradiction:
Improvesleep monitoring accuracyVSAvoidmanufacturing complexity
Core Design Contradiction:
Measurement precisionVSEase of manufacture

Solution Approach 1:

Sensors and control elements are integrated into the existing mattress structure layers. Pressure sensors are embedded within the mattress foam, temperature elements are incorporated into the comfort layers, and wiring is routed through pre-defined channels. This nesting approach allows high-precision monitoring while maintaining relatively simple manufacturing processes by adding sensors to existing structures rather than creating entirely new complex assemblies.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Ease of operation

If real-time adjustment capabilities are added, then user comfort is improved, but energy consumption increases

Engineering Contradiction:
Improvereal-time adjustment capabilityVSAvoidenergy consumption
Core Design Contradiction:
Ease of operationVSUse of energy by moving object

Solution Approach 1:

The system uses periodic sensing and incremental adjustment rather than continuous operation. Sensors take measurements at regular intervals, and the control system makes stepwise adjustments to firmness, temperature, and position based on detected changes in user state. This periodic approach enables real-time comfort adaptation while significantly reducing energy consumption compared to continuous adjustment mechanisms.

Inventive Principle:
Principle #19Periodic action

AI summary

An air mattress adjustment method includes adjusting the air mattress to a received user pressure setting, learning a level of pressure in the air mattress at a first plurality of times with respect to the user pressure setting, monitoring the level of pressure in the air mattress at a second plurality of times, determining that the pressure of the air mattress at one of the second plurality of times is out of range, and based on the determining, adjusting the pressure of the air mattress.
