Vacuum Cleaner Dual Locking Structure for Dust Bin Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum cleaners face issues with the undesired separation of dust bins and filter casings, complex structures that complicate fabrication, and difficulties in mounting or demounting these components individually, leading to potential separation when the vacuum is tilted.
Innovation Solution
A vacuum cleaner design featuring a dual locking structure with recessed first locking holes on the dust bin and corresponding locking members, along with filter casing locking portions and members, allows for secure retention and easy mounting/demounting of the dust bin and filter casing, preventing separation even when the vacuum is tilted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fastening lever and sliding portion are used to secure the dust bin and filter casing, then the components can be removably secured, but the structure becomes complicated and fabrication becomes difficult
Solution Approach 1:
The locking mechanism is segmented into separate locking holes in the dust bin and corresponding locking protrusions in the main body, allowing independent engagement points that simplify the overall structure while maintaining secure retention
Solution Approach 2:
The locking function is extracted from a complex fastening lever mechanism and implemented through simple locking holes and protrusions, removing unnecessary complexity while preserving the securing function
2Reliability
If a complex locking structure is used to prevent separation, then reliability improves, but the number of parts increases and fabrication becomes difficult
Solution Approach 1:
The locking mechanism uses multiple simple locking holes and corresponding protrusions distributed at different locations, segmenting the locking function into simple geometric features that are easy to manufacture while collectively providing reliable prevention of separation
Solution Approach 2:
Locking holes are positioned at specific locations (front and rear ends) of the dust bin to provide localized engagement points that prevent separation in critical areas without requiring a complex overall structure
3Ease of manufacture
If a simple fastening structure is used, then fabrication is easier, but the dust bin and filter casing may undesirably separate when the vacuum cleaner is tilted
Solution Approach 1:
Multiple locking holes are positioned at both the front end and rear end of the dust bin, creating distributed engagement points that provide stable retention during tilting while maintaining simple, easy-to-manufacture geometry
Solution Approach 2:
The locking holes extend in the vertical direction from the lower portion to a predetermined height, adding a vertical dimension to the locking engagement that prevents separation during tilting while keeping the structure simple
4Device complexity
If a unified fastening mechanism is used for dust bin and filter casing, then the structure is simpler, but it is difficult to mount or demount them individually
Solution Approach 1:
The locking mechanism is designed with locking holes in the dust bin that can engage with locking protrusions independently, allowing the dust bin to be mounted or demounted separately from the filter casing while maintaining a relatively simple overall structure
Solution Approach 2:
The locking mechanism allows for dynamic operation where the dust bin can be independently mounted or demounted by engaging or disengaging its locking holes with the locking protrusions, providing operational flexibility without significant structural complexity

AI summary
A vacuum cleaner having a dual locking structure is provided. The vacuum cleaner includes a brush assembly, a main body connected to the brush assembly, a dust bin arranged on the main body, a fastening unit to move the dust bin to a fastened or unfastened state, and a filter casing. The dust bin includes one or more first locking holes and the main body includes one or dust bin locking members to be engaged with the first locking holes so that the dust bin, in an unfastened state, is removably retained in the main body. The filter casing includes one or more filter casing locking portions and the main body includes one or more filter casing locking members to be engaged with the filter casing locking portions so that the filter casing in the unfastened state is removably retained in the main body.
