Solution Overview

Problem

Inflatable products, such as inflatable mattresses, face challenges in maintaining consistent air pressure due to expansion and deformation, leading to inefficient inflation and deflation processes, and existing air pumps lack automatic pressure regulation, requiring manual intervention and increasing user inconvenience.

Innovation Solution

An air pump control system comprising an air pump, a switching driving device, and an air pressure sensor, connected to a central control unit that adjusts the air pump's operation based on internal pressure readings to maintain stable pressure, using additional air supplementing pumps to maintain optimal conditions.

Solution Approach 1:

The patent replaces manual mechanical pressure sensing (pressing the inflatable product) with electronic pressure sensors that automatically detect and transmit pressure data to the control unit, enabling precise digital measurement without complex mechanical mechanisms

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

Solution Approach 2:

The system enables self-service pressure monitoring and control where the pressure sensor continuously monitors air pressure and the control unit automatically adjusts pump operation based on detected pressure levels, eliminating the need for manual pressure checking and control

Solution Approach 1:

The patent implements a feedback control loop where the pressure sensor continuously monitors air pressure and transmits data to the control unit, which then adjusts the air pump operation accordingly to maintain stable pressure within the inflatable product

Inventive Principle:

Solution Approach 1:

The patent divides the air supply function into two separate pumps: the air pump for rapid inflation and the air supplementing pump for maintaining pressure. This segmentation allows each pump to be optimized for its specific function and enables independent control based on pressure conditions

Inventive Principle:

Solution Approach 2:

The system dynamically switches between the air pump and air supplementing pump based on real-time pressure conditions. The control unit activates the appropriate pump according to whether the product needs rapid inflation or gradual pressure maintenance, optimizing system performance and complexity management

AI summary

An air pump control system includes a first air pump and a second air pump for inflating or deflating an inflatable body; a switching driving device connected to the air pumps for driving the switching between two or more air passages; and an air pressure sensor for detecting an internal air pressure value of the inflatable body, and sending an internal pressure signal to a central control unit, which is connected to the air pumps, the switching driving device, and the air pressure sensor. The central control unit sends a driving signal to the switching driving device to activate the switching between the air passages, and sends an activation or deactivation signal to the air pumps according to the detected internal air pressure value and a pre-set inflating air pressure value, to activate or deactivate the air pumps. An air pump control method is also disclosed herein.
