Dual-Pressure Inflation Pump for Tires and Inflatable Gear
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electric pumps are limited in their functionality, requiring separate devices for inflating automobile tires and other inflatable items, leading to economic burden and reduced portability.
Innovation Solution
A multipurpose inflation pump with dual inflation units, one for low-pressure items like inflatable beds or boats, and another for high-pressure automobile tires, integrated with a controller to manage airflow and pressure settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single conventional electric pump is used, then it can rapidly inflate or deflate inflatable beds or boats, but it cannot inflate automobile tires requiring higher air pressure
Solution Approach 1:
The pump system is divided into two independent inflation units: a first inflation unit with a blower for low-pressure items (inflatable beds, boats) and a second inflation unit with a pressure air pump for high-pressure items (automobile tires). Each unit has its own motor, piston cylinder, and control mechanisms, allowing them to operate independently or separately as needed.
Solution Approach 2:
The single pump device is designed to perform multiple functions by integrating two different inflation units with different pressure capabilities. The device can switch between the first inflation unit for low-pressure applications and the second inflation unit for high-pressure applications, making one device universally applicable to both inflatable beds/boats and automobile tires.
2Adaptability or versatility
If consumers carry two separate inflation pumps, then one can handle high-pressure tire inflation and the other can handle low-pressure inflatable items, but this increases the number of items carried and reduces portability
Solution Approach 1:
The patent combines two previously separate inflation pumps into a single integrated device. The housing contains both the first inflation unit (blower) and the second inflation unit (pressure air pump), along with a shared control system and air outlet. This merging eliminates the need to carry two separate devices while maintaining all necessary functions.
Solution Approach 2:
By designing a universal pump that can handle both low-pressure and high-pressure inflation tasks, the device replaces the need for multiple specialized pumps. The controller automatically selects the appropriate inflation unit based on the required pressure, providing a single portable solution for all inflation needs.
3Ease of operation
If a single conventional electric pump is used, then it is portable and easy to carry, but it requires consumers to purchase multiple pumps for different inflation needs, causing economic burden
Solution Approach 1:
The pump system is divided into two independent inflation units: a first inflation unit with a blower for low-pressure items (inflatable beds, boats) and a second inflation unit with a pressure air pump for high-pressure items (automobile tires). Each unit has its own motor, piston cylinder, and control mechanisms, allowing them to operate independently or separately as needed.
Solution Approach 2:
The single pump device is designed to perform multiple functions by integrating two different inflation units with different pressure capabilities. The device can switch between the first inflation unit for low-pressure applications and the second inflation unit for high-pressure applications, making one device universally applicable to both inflatable beds/boats and automobile tires.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables efficient inflation and deflation of both low-pressure and high-pressure items using a single device, reducing the need for multiple pumps and saving costs.
Implementation Method 1
an end of the second motor is provided with a first cooling fan. The first cooling fan may dissipate heat for the second motor better.
Implementation Method 2
The blower and the first pressure air pump may operate in cooperation, and the blower may provide a large flow of air with less pressure to rapidly inflate in an initial inflation
Implementation Method 3
a first one-way outlet valve is disposed in the shell proximal to the outlet of the blower and configured to flow out one-way air towards the inflation conduit

AI summary
A multipurpose inflation pump is provided. The multipurpose inflation pump includes a housing provided with a device cavity and a storage cavity which is configured to place an accessory. The device cavity is provided with a first inflation unit and a second inflation unit, and an inflation pressure of the first inflation unit is lower than an inflation pressure of the second inflation unit. The multipurpose inflation pump can not only rapidly inflate and deflate an inflatable bed, an inflatable boat, etc., but also provide higher inflation pressure to inflate an automobile tire, thus combining multiple uses in a single machine and helping consumers save cost.
