Rotatable Inner Casing Air Pump for Inflatable Products
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air pumps for inflatable products require complex switching between inflation and deflation functions, complicating the manufacturing process and user operation.
Innovation Solution
A built-in electric air pump with a simple structure featuring an outer and inner casing, motor, and impeller, where the inner casing's rotation controls a tongue to open or close the air opening for inflation or deflation, eliminating the need for additional buttons to switch functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional air pump uses separate inflation and deflation ports with manual switching, then the pump can perform both functions, but the structure becomes complicated and operation becomes complex
Solution Approach 1:
The air pump integrates both inflation and deflation functions into a single device by using a rotatable inner casing that directs airflow to different ports. The inner casing can rotate to connect the impeller to either the inflation port or the deflation port, eliminating the need for separate pumps or complex switching mechanisms while maintaining both functions.
Solution Approach 2:
The inner casing is designed to be rotatable rather than fixed, allowing dynamic reconfiguration of the airflow path. This rotation enables the pump to switch between inflation and deflation modes by changing the angular position of the inner casing, thereby connecting different ports to the impeller without requiring additional mechanical switching components.
2Adaptability or versatility
If a conventional air pump requires manual selection of inflation or deflation port, then the pump can handle both functions, but the operation becomes inconvenient and confusing
Solution Approach 1:
The air pump automatically switches between inflation and deflation modes through the rotation of the inner casing, eliminating the need for manual port selection by the user. The system self-regulates the airflow direction based on the rotational position of the inner casing, making the operation simpler and more intuitive while maintaining both functions.
3Adaptability or versatility
If a conventional air pump uses additional buttons for function switching, then the pump can perform both functions, but the assembly procedure becomes more complex and production is less efficient
Solution Approach 1:
The air pump merges the inflation and deflation functions into a single integrated mechanism where the rotatable inner casing serves as both the airflow director and the mode-switching mechanism. This eliminates the need for separate buttons or switches, reducing the number of components and simplifying the assembly procedure while maintaining both functions.
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
Simplifies the assembly and operation of inflatable products by integrating the inflation and deflation functions into a single, easy-to-manufacture unit, reducing production complexity and user confusion.
Implementation Method 1
The impeller is mounted onto an output shaft of the motor and driven to rotate by the motor. The impeller is located in the air cavity.
Implementation Method 2
the air pump is started to pump air into the inflatable space of the inflatable product through the inflation port
Implementation Method 3
The motor is clamped and fixed between the left casing and the right casing. The motor is located in the mounting cavity.
Implementation Method 4
The second air opening is provided with a tongue configured to close the second air opening or to open the second air opening by swinging into the inflatable product
Implementation Method 5
The inner casing is rotatably disposed in the accommodating cavity. The protruding portion of the inner casing along with the rotation of the inner casing controls the tongue to open or close the second air opening
Implementation Method 6
An outer wall of the inner casing is provided with a protruding portion for pushing the tongue to swing into the inflatable product so as to open the second air opening
