Integrated Inflation Deflation Air Pump with Universal Port

Solution Overview

Problem

Existing air pumps for inflatable products require separate inflation and deflation pumps, leading to increased cost and space usage, as well as complex and inconvenient operation.

Innovation Solution

An integrated inflation and deflation air pump with a universal air port, inflation port, and deflation port, along with an adjusting assembly and control assembly, allowing for flexible switching between inflation and deflation modes without the need for pump replacement or port connection changes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If separate inflation and deflation pumps are installed, then inflation and deflation functions are achieved, but cost and space occupancy increase

Engineering Contradiction:

Improveinflation and deflation functionsVSAvoidspace occupancy

Core Design Contradiction:

Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The single air pump is designed with multiple ports (first air port, second air port, third air port) and a controllable valve system that enables it to perform both inflation and deflation functions. The pump body can switch between different working modes by controlling the opening and closing of valves, allowing one device to replace what would traditionally require two separate pumps.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The invention merges the functions of separate inflation and deflation pumps into a single integrated air pump unit. By combining multiple air ports and a unified pump body with controllable valve mechanisms, the design consolidates what would be two independent devices into one, reducing both space occupancy and overall system cost.

Inventive Principle:

Principle #5Merging (Combining)

3Adaptability or versatility

If air pump is detachable relative to air port, then connection flexibility is improved, but operation complexity increases

Engineering Contradiction:

Improveconnection flexibilityVSAvoidoperation complexity

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The air pump is equipped with a universal air port interface that can accommodate different connection types. The pump body includes multiple air ports (first, second, and third air ports) with valve control mechanisms that enable the single device to handle both inflation and deflation operations through a unified connection interface, eliminating the need for detachable pump configurations.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

Instead of making the pump detachable to achieve connection flexibility, the invention inverts the approach by making the connection interface universal and the pump body fixed. The valve control system is designed to redirect airflow based on operational mode, achieving flexibility through internal valve mechanisms rather than external detachable connections.

Inventive Principle:

Principle #13The other way round (Inversion)

AI summary

The present application relates to an integrated inflation and deflation air pump, including a housing, a pump body, an adjusting assembly and a control assembly. The housing is provided with a universal air port, an inflation port, and a deflation port. When in an inflated state, the universal air port is in communication with the air inlet, the inflation port is in communication with the air outlet, and, when in a deflated state, the universal air port is in communication with the air outlet, the deflation port is in communication with the air inlet, the adjusting assembly is provided between the housing and pump body and is configured to control a communication relationship between the air inlet, air outlet, universal air port, inflation port, and deflation port. The control assembly is installed on the housing, electrically connected to the pump body to control operation of the pump body.
