Vacuum Dust Container Compression for Higher Collection Capacity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vacuum cleaners have a dust collection capacity issue, as the dusts stored in the dust container occupy a large volume relative to their weight, making frequent emptying inconvenient and reducing dust collection performance.
Innovation Solution
A vacuum cleaner design that includes a dust container with a compressible dust storage chamber and a lower cover for easy access, utilizing a pressing member and transmission mechanism to compress and discharge dusts efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If dusts are stored in the dust storage chamber without compression, then the dusts occupy a large volume relative to their weight, but the dust collection capacity of the dust container is limited and requires frequent emptying
Solution Approach 1:
The patent applies compression to change the physical state of dusts from loose to compact, increasing their density. The pressing member mechanically compresses the dusts in the dust storage chamber, reducing the volume they occupy while maintaining the same mass, thereby increasing the dust collection capacity of the container
Solution Approach 2:
The pressing member is designed to be movable rather than fixed, allowing it to dynamically compress dusts as they are deposited. The pressing member can move to follow the accumulation of dusts, maintaining continuous compression and maximizing space utilization in the dust storage chamber
2Ease of operation
If the dust container is designed with a fixed structure, then the manufacturing is simple, but the dusts cannot be easily discharged and the device complexity increases with additional discharge mechanisms
Solution Approach 1:
The lower cover is designed to be rotatable rather than fixed, creating a dynamic discharge mechanism. When the lower cover rotates, it tilts the dust storage chamber to facilitate dust discharge under gravity, providing an easy-to-operate dust emptying function without requiring complex mechanical discharge systems
Solution Approach 2:
By rotating the lower cover, the dust storage chamber is tilted to create a gravity-assisted discharge path. This allows dusts to be discharged easily under the action of gravity alone, without requiring additional motors or complex mechanical ejection mechanisms
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
The compression of dusts maximizes the dust container's capacity, reduces the need for frequent emptying, and enhances user convenience by allowing easy discharge of dusts through the rotating lower cover.
Implementation Method 1
a pressing member movably disposed inside the dust collection body to compress the dusts within the dust storage chamber
Implementation Method 2
a transmission part disposed under the lower cover to transmit a power transmitted from the outside; and a connection member disposed above the lower cover to transmit the power transmitted from the transmission part into the rotation shaft
