Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air mattresses require manual inflation and deflation, which is inconvenient and time-consuming, as they typically have separate inflation and deflation ports at different locations.
Innovation Solution
An air mattress with an integrated inflation and deflation device that includes a switching mechanism, allowing for automatic inflation and deflation through a single air outlet, using a driving device and switching device to control airflow for easy operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate inflation and deflation ports are provided at different positions, then the air mattress can be inflated and deflated, but the operation becomes inconvenient and time-consuming
Solution Approach 1:
The patent combines the inflation port and deflation port into a single integrated port structure. The switching device allows the same port to be used for both inflation and deflation operations by internally directing airflow based on the selected mode, thereby reducing the number of external ports from two to one and improving operational convenience.
Solution Approach 2:
The single port is designed to serve multiple functions - it acts as both an inflation port and a deflation port. The switching device enables this port to be dynamically configured for different functions, making it a universal interface that eliminates the need for separate dedicated ports for each operation.
2Productivity
If manual inflation and deflation are required, then the structure can be simple, but the process becomes time-consuming and less efficient
Solution Approach 1:
The air mattress system performs inflation and deflation operations automatically without requiring manual pumping or external intervention. The built-in driving device self-regulates the airflow through the switching device to complete the inflation or deflation process based on user selection, thereby increasing productivity while maintaining reasonable structural simplicity.
3Ease of operation
If a switching device is added to enable automatic inflation and deflation through a single port, then operational convenience improves, but the device complexity increases
Solution Approach 1:
The switching device acts as an intermediary component that manages the airflow path between the single port and the internal chambers. It provides a controlled mechanism for directing air flow without requiring complex external modifications, balancing the added internal complexity with the significant simplification of external port structure.

Function Achieved in This Case
Enables convenient and time-saving automatic inflation and deflation of the air mattress without manual intervention, improving usability and efficiency.
Implementation Method 1
the driving device is configured to drive external air to pass through the first air inlet and the first air outlet in sequence to form an inflation airflow discharged from the first air outlet
Implementation Method 2
the driving device is configured to drive the air in the inflation chamber to pass through the first air inlet and the first air outlet in sequence to form an exhaust airflow discharged from the first air outlet to the outside

AI summary
An air mattress relates to the field of air mattresses. The air mattress includes a mattress main body, an inflation and deflation device. The mattress main body is provided with an inflation chamber and a first airflow channel. The inflation chamber is communicated to the first airflow channel. The inflation and deflation device includes a driving device, a first air inlet and a first air outlet. When the first air outlet is communicated to the first airflow channel, the inflation and deflation device is in an inflation state, and the driving device is configured to drive external air to pass through the first air inlet and the first air outlet in sequence to form an inflation airflow discharged from the first air outlet; and the inflation airflow discharged from the first air outlet fills the inflation chamber through the first airflow channel to inflate the mattress main body.
