Dust collection box and sweeping robot
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robot vacuum cleaners require complex operations to remove pollutants from the dust collection box, which is inconvenient for users.
Innovation Solution
A dust collection box with a rotatable lower lid that snap-fits to close the dust extraction port, allowing easy opening and removal of pollutants, and an upper lid for detachable filter access, integrated into a robot vacuum cleaner design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the dust collection box uses a fixed lid structure, then the seal and containment are improved, but the ease of operation for removing pollutants deteriorates
Solution Approach 1:
The lid is divided into two separate lids: a first lid that rotates relative to the box body and a second lid that detaches from the box body. This segmentation allows the first lid to maintain seal during rotation while the second lid can be completely removed for filter access, resolving the contradiction between maintaining containment and enabling easy operation.
Solution Approach 2:
The first lid is designed to rotate dynamically relative to the box body rather than being fixed or fully removable. This dynamic design allows the lid to transition between closed (maintaining seal) and open (allowing pollutant removal) positions, resolving the contradiction between reliability and ease of operation.
2Reliability
If the dust collection box requires filter removal for pollutant access, then the filtration effectiveness is improved, but the device complexity and ease of operation deteriorate
Solution Approach 1:
The lid system is segmented into a first lid for pollutant removal and a second lid for filter access. The first lid can be opened independently to remove pollutants without affecting the second lid or filter assembly, allowing pollutant removal while maintaining filter integrity and reducing operational complexity.
Solution Approach 2:
The first lid is extracted as a separate, independently operable component from the second lid and filter assembly. This extraction allows the first lid to be removed for pollutant access without requiring removal of the filter-containing second lid, simplifying the operation while maintaining filtration effectiveness.
3Ease of operation
If the dust extraction port remains open, then the ease of operation for pollutant removal is improved, but pollutant leakage and reliability deteriorate
Solution Approach 1:
The first lid provides a dynamic sealing solution that can rotate to open positions for pollutant removal while maintaining contact with the box body to prevent leakage. This dynamic sealing allows the port to be effectively open for operation while preventing harmful pollutant leakage.
Solution Approach 2:
The first lid acts as a flexible sealing element that can pivot between closed and open positions. When closed, it forms a seal to prevent pollutant leakage; when opened, it allows pollutant removal. This flexible design resolves the contradiction between ease of operation and prevention of harmful factors.
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
Facilitates convenient and efficient removal of dust and rubbish from the dust collection box without needing to remove the filter, improving user experience and extending the service life of the robot vacuum cleaner by preventing pollutant leakage.
Implementation Method 1
the second lateral portion being snap-fitted with the box body through a first snap structure
Implementation Method 2
the button is rotatably arranged to the box body through the rotating shaft; the button is able to swing, with respect to the box body, between a first position and a second position

AI summary
A dust collection box (100) and a robot vacuum cleaner (200) are disclosed. The dust collection box (100) includes a box body (10) and a lower lid (20). The box body (10) defines a dust extraction port (11) in the bottom thereof. The lower lid (20) includes a first lateral portion (21) and a second lateral portion (22) opposite to each other. The first lateral portion (21) is rotatably connected with the box body (10) to enable the lower lid (20) to open or close the dust extraction port (11). When the lower lid (20) closes the dust extraction port (11), the second lateral portion (22) is snap-fitted with the box body (10) through a first snap structure (30).
