Electric Air Pump Pressure Detection for Closed-Loop Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air pumps for inflatable products like mattresses cannot accurately measure internal air pressure, leading to potential damage from excessive pressure or insufficient inflation, affecting comfort and functionality.
Innovation Solution
An electric air pump equipped with an air pressure detection unit and control module that regulates inflation and deflation, using a main pump and auxiliary pump to maintain optimal pressure by detecting internal air pressure and automatically adjusting motor operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If air pressure detection unit and control module are added, then air pressure control precision is improved, but device complexity increases
Solution Approach 1:
The patent implements a feedback control system where the air pressure detection unit continuously monitors the air pressure in the inflatable product and sends signals to the control module. The control module adjusts the inflation/deflation motors based on this feedback to maintain the air pressure within the preset range, resolving the contradiction by enabling precise control through closed-loop feedback.
Solution Approach 2:
The patent replaces manual air pressure monitoring and adjustment with an automated electronic control system. The air pressure detection unit uses electronic sensors instead of mechanical gauges, and the control module uses electronic control circuits to automatically adjust motor operation, substituting mechanical control with electronic automation to improve precision while managing complexity.
2Adaptability or versatility
If dual motor system (inflation and deflation) is used, then operational versatility is improved, but device complexity increases
Solution Approach 1:
The patent employs a dual motor system where the first motor drives the inflation module and the second motor drives the deflation module. This multi-functional design allows the air pump to perform both inflation and deflation operations independently, enhancing operational versatility. The control module intelligently selects which motor to operate based on the current air pressure conditions, managing the complexity through coordinated control.
Solution Approach 2:
The patent segments the motor system into two independent motor units: an inflation motor for increasing air pressure and a deflation motor for decreasing air pressure. This segmentation allows each motor to be optimized for its specific function and enables independent control, improving versatility while the control module manages the overall system complexity through coordinated operation.
