Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum cleaners face issues with dust bin clogging, inefficient dust compression, and difficulty in cleaning and maintaining the dust separation system, leading to frequent emptying and potential contamination of components.
Innovation Solution
A cleaner design with a dust bin that can be separated from the motor housing, featuring a compression part for dust compaction, a manipulation part for easy cleaning, and a transmission part for smooth operation, ensuring a sufficient interval between the dust bin and cyclone to prevent foreign substance entrapment, and allowing water washability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the dust bin is separated from the motor housing, then ease of cleaning and maintenance is improved, but sealing force between components deteriorates
Solution Approach 1:
The dust bin is designed as a separable component from the motor housing, allowing users to easily detach and clean the dust bin without disassembling the entire vacuum cleaner. This segmentation improves accessibility for cleaning while maintaining reliable sealing through dedicated sealing structures at the interface between the dust bin and motor housing.
2Loss of time
If the compression part is added to compress dust, then dust bin emptying frequency is reduced, but device complexity increases
Solution Approach 1:
The compression part incorporates a movable compression plate that can be dynamically positioned to compress dust in the dust bin. This dynamic mechanism allows the system to adapt to varying dust volumes and provides effective compression without requiring a completely new dust bin design, thereby reducing emptying frequency while controlling overall device complexity.
3Reliability
If the interval between dust bin and cyclone is increased, then foreign substance entrapment is prevented, but device volume increases
Solution Approach 1:
The design increases the interval between the dust bin and cyclone by utilizing vertical spacing rather than horizontal expansion. This dimensional approach prevents foreign substance entrapment while minimizing the overall device volume by efficiently arranging components in the vertical direction.
4Ease of operation
If the manipulation part is positioned outside motor housing, then ease of operation is improved, but device complexity increases
Solution Approach 1:
A transmission part serves as an intermediary mechanism that connects the manipulation part positioned outside the motor housing to the compression part inside the dust bin. This intermediary transmission structure allows users to easily operate the compression function from an accessible external position while maintaining a relatively simple overall device architecture through efficient mechanical coupling.
