Vacuum Dust Container Compression and Self-Cleaning Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vacuum cleaners face inefficiencies due to low dust collection capacity in dust containers, requiring frequent emptying and accumulation of dusts at low density, and the risk of foreign materials getting caught between components.
Innovation Solution
Incorporating a dust container with a pressing member to compress dusts and a cleaning member to clean the inner surface, preventing foreign materials from being caught and enhancing dust storage capacity and visibility of accumulated dusts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If dusts are stored in the dust storage part without compression, then the dusts can be easily stored, but the dust collection capacity is limited and the volume occupied is large
Solution Approach 1:
The pressing member changes the physical state of dusts from loose to compressed by applying mechanical pressure, thereby increasing the density and collection capacity of the dust storage part while reducing the volume occupied by the same amount of dust
2Quantity of substance
If the dust container is designed with larger capacity, then dust collection capacity increases, but the device complexity increases
Solution Approach 1:
The pressing member and cleaning member are integrated into a single rotatable assembly that performs multiple functions: compressing dusts, cleaning the inner wall of the dust collection body, and preventing foreign materials from being caught, thereby increasing dust collection capacity without proportionally increasing device complexity
Solution Approach 2:
The pressing member serves multiple functions simultaneously: it compresses dusts to increase capacity, the cleaning member attached to it cleans the inner wall, and the rotation shaft structure prevents foreign materials from being caught, making the system more efficient without adding separate dedicated components for each function
3Quantity of substance
If the pressing member rotates to compress dusts, then dust collection capacity increases, but foreign materials may be caught between the pressing member and dust collection body
Solution Approach 1:
The cleaning member acts as an intermediary between the pressing member and the dust collection body, removing foreign materials from the inner wall surface before they can be caught between the pressing member and the dust collection body during rotation, thus preventing harmful effects while maintaining compression functionality
4Reliability
If the dust container is emptied frequently to maintain performance, then dust collection performance is maintained, but the loss of time increases
Solution Approach 1:
The cleaning member continuously cleans the inner wall of the dust collection body during the compression process, preventing dust accumulation and foreign material buildup in advance, which maintains dust collection performance without requiring frequent manual emptying operations
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
