Solution Overview

Problem

Conventional electric inflating air pumps suffer from low inflation efficiency and long inflation times due to increasing pressure and air leakage during the inflation process, leading to poor working efficiency.

Innovation Solution

A fast electric inflating air pump design featuring a housing with a controller, blower, motor, inlet tube, and inflating tube, where the controller instructs the blower to operate until a predetermined pressure is reached, then the motor drives a piston to move back and forth to achieve high-pressure inflation, utilizing a one-way valve and a transmission assembly for efficient air flow and pressure conversion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a single inflation method driven by motor is used, then the structure is simple, but the inflation efficiency is low and inflation time is long

Engineering Contradiction:
Improveinflation efficiencyVSAvoidinflation method complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The inflation process is segmented into two distinct stages: a first inflation stage using a blower for rapid initial inflation, and a second inflation stage using a motor-driven piston for high-pressure finishing. This segmentation allows each component to operate in its optimal performance range, thereby improving overall inflation efficiency while managing system complexity through functional division.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system dynamically switches between two inflation methods based on the inflation progress. The controller automatically transitions from the blower-driven first inflation method to the motor-driven second inflation method when the first method can no longer effectively increase pressure, creating a dynamic adaptive inflation system that optimizes efficiency throughout the entire inflation process.

Inventive Principle:
Principle #15Dynamics

2Loss of time

If single inflation method is used, then the control system is simple, but the inflation time is long

Engineering Contradiction:
Improveinflation timeVSAvoidcontrol system complexity
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The inflation process employs periodic action by alternating between two distinct inflation phases. The blower operates during the first phase to rapidly establish pressure, then the system transitions to the motor-driven piston for the second phase. This periodic switching between different inflation mechanisms significantly reduces total inflation time while the controller manages the transition automatically.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The blower performs preliminary action by rapidly inflating the object to an initial pressure level before the motor-driven piston takes over. This preliminary inflation stage prepares the system for the subsequent high-pressure stage, reducing the time required for the entire inflation process by handling the low-pressure phase more efficiently.

Inventive Principle:
Principle #10Preliminary action

3Productivity

If single inflation method is used, then the system is simple, but air leakage reduces working efficiency

Engineering Contradiction:
Improveworking efficiencyVSAvoidinflation system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The inflation system is segmented into two functional components: a blower for initial inflation and a motor-driven piston for high-pressure inflation. This segmentation allows the system to address air leakage issues differently at each stage, with the piston-based second stage providing more effective pressure maintenance and leakage compensation, thereby improving working efficiency despite increased system complexity.

Inventive Principle:
Principle #1Segmentation

AI summary

The present invention discloses a fast inflating air pump, including a housing, an inflating tube, an inlet tube, a motor, a transmission assembly and a controller housed in the housing. A blower is arranged in the inlet tube for increasing air pressure to the inflating port. A piston is at least partially contained in the inflating tube, and the piston is driven by the motor via the transmission assembly so as to slide back and forth linearly for increasing air pressure in the inflating tube. A one-way valve is installed in the communicating pipe for only allowing air flow into the inflating tube. The controller instructs the motor to drive the piston to slide back and forth in the inflation tube on condition that the blower stops working until the air inflation pressure increases to a predetermined threshold, then the controller instructs the motor to stop operating.
