Solution Overview

Problem

Existing pressure control systems for inflatable devices require users to recall preferred pressure settings, which can be arbitrary and lack rapid adjustment, making them impractical for devices with large volumes, such as mattresses, especially for posture control applications.

Innovation Solution

A control device with a plurality of control elements that allows users to adjust pressure based on tactile feedback, using a pressure controller with sensors and a microcontroller to automatically establish preferred and additional pressure settings without the need for indicia, enabling rapid and precise pressure adjustments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional pressure control systems with discrete settings are used, then the device provides predefined pressure levels, but the user cannot quickly adjust to preferred pressure and must recall arbitrary settings

Engineering Contradiction:
Improvepressure adjustment easeVSAvoidtime to adjust pressure
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The patent replaces mechanical pressure adjustment mechanisms with electronic sensors and digital control systems. Pressure sensors continuously monitor the actual pressure, and a microprocessor compares it with the desired pressure from memory, automatically controlling the pump and valve to achieve the target pressure without manual intervention.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system stores the user's preferred pressure settings in memory and automatically retrieves and applies them without requiring the user to recall or manually adjust settings. The controller autonomously maintains the desired pressure by monitoring sensor data and adjusting the inflation/deflation mechanisms as needed.

Inventive Principle:
Principle #25Self-service

2Adaptability or versatility

If multiple discrete pressure settings are provided, then the system offers various pressure levels, but the settings are arbitrary and do not provide rapid adjustment for large volume devices

Engineering Contradiction:
Improvepressure level optionsVSAvoidspeed of pressure adjustment
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The system transitions from static discrete pressure settings to dynamic continuous pressure control. The controller can adjust pressure in real-time based on sensor feedback, allowing smooth transitions between pressure levels and rapid adaptation to user needs, especially important for large volume devices like mattresses.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

Pressure sensors provide continuous feedback to the controller about the actual pressure in the device. The controller compares this feedback with the desired pressure from memory and automatically adjusts the pump and valve operations to eliminate any deviation, enabling rapid and precise pressure adjustment.

Inventive Principle:
Principle #23Feedback

3Ease of operation

If manual pressure adjustment is used, then the user can control pressure, but it requires user recall of settings and lacks precision for posture control applications

Engineering Contradiction:
Improveuser control capabilityVSAvoidpressure control precision
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The patent replaces manual pressure estimation with electronic pressure sensing. Pressure sensors provide precise measurement of the actual pressure, and the microprocessor uses this data to automatically control the pressure, eliminating the imprecision of manual adjustment and user recall.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The controller acts as an intermediary between the user's desired pressure setting and the actual pressure in the device. It translates the stored pressure preference into precise control signals for the pump and valve, ensuring the actual pressure matches the desired pressure with high accuracy.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

In one aspect, the invention provides a method for a user to adjust a pressure in an inflatable device. The method includes acts of adjusting the pressure in the inflatable device with a control device to a pressure preferred by the user, where the pressure preferred by the user has a first value, and establishing a first setting corresponding to the pressure preferred by the user with the control device, and automatically establishing a second setting corresponding to a second pressure having a second value once the first setting is established, where the second value differs from the first value by a predetermined amount.
