Dual Air Compressor Assembly for Variable Pressure Inflation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air compressing devices are limited in their ability to inflate various air facilities as they either generate low pressure with high flow for air beds and cushions or high pressure with low flow for vehicle tires, making them inefficient for inflating multiple types of air-based equipment simultaneously.
Innovation Solution
An air compressing assembly featuring two distinct air compressing devices: a fan-based device for generating lower pressure with higher flow and a piston-based device for higher pressure with lower flow, both connected to an air tank and controlled by a central device to manage air distribution efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a centrifugal type fan device is used, then a pressurized air of lower air pressure and greater flowing quantity is generated, but it cannot be used to inflate vehicle tires
Solution Approach 1:
The air compressing assembly is divided into two separate air compressing devices: a first device (centrifugal fan) for generating low-pressure high-flow air for air facilities, and a second device (piston compressor) for generating high-pressure low-flow air for vehicle tires. Each device is optimized for its specific function, resolving the contradiction between pressure and flowing quantity requirements.
2Stress or pressure
If a piston type air compressing device is used, then a pressurized air of greater air pressure and decreased flowing quantity is generated, but it takes a long time to inflate air beds and air cushions
Solution Approach 1:
The system segments the inflation task by using the piston compressor only for high-pressure applications (vehicle tires) while the centrifugal fan handles low-pressure applications (air beds, cushions). This segmentation allows each device to operate in its optimal performance range, maintaining high inflation speed for air facilities while providing necessary pressure for tires.
3Adaptability or versatility
If a single air compressing device is used, then the device complexity is reduced, but it cannot efficiently inflate different types of air facilities with different pressure requirements
Solution Approach 1:
The system uses two specialized compressing devices instead of one general-purpose device. The first device (centrifugal fan) is dedicated to air facilities requiring low pressure, while the second device (piston compressor) is dedicated to applications requiring high pressure. This segmentation increases adaptability to different air facilities while keeping each individual device relatively simple.
Solution Approach 2:
Both air compressing devices connect to a common air tank and control system, creating a multi-functional assembly that can serve multiple purposes: inflating vehicle tires, air beds, air cushions, and hovercrafts. The shared control device and air tank provide universal coordination across different functions.
