Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience when removing filled pollutants from the dust collection box in robot vacuum cleaners, as existing methods require complex operations.
Innovation Solution
A dust collection box design with a rotatable lower lid and snap-fit mechanism allows easy opening and closing of the dust extraction port, enabling simple pollutant removal without needing to remove the filter device, and includes a button for easy operation and a bump for enhanced tightness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the dust collection box uses a traditional fixed lid design, then the structure is simple and reliable, but the user needs to perform complicated operations to remove pollutants
Solution Approach 1:
The lid is divided into two lateral portions (first lateral portion and second lateral portion) that can move independently. The first lateral portion rotates to open the dust extraction port, while the second lateral portion remains connected to the box body through the snap structure, allowing simple pollutant removal without moving the entire lid assembly.
Solution Approach 2:
The lid transitions from a static fixed design to a dynamic design where the first lateral portion can rotate around a rotation axis. This dynamic capability enables the dust extraction port to be opened easily by rotating the first lateral portion, significantly improving pollutant removal convenience.
2Ease of operation
If the lower lid is made detachable for easy pollutant removal, then the ease of operation improves, but the risk of pollution to internal components increases
Solution Approach 1:
The first lateral portion is nested within the box body structure through the snap structure connection. When the first lateral portion rotates to open the dust extraction port, it remains partially contained within the box body boundaries, creating a physical barrier that prevents pollutants from escaping and contaminating internal components while still allowing easy access for pollutant removal.
Solution Approach 2:
The snap structure acts as an intermediary mechanism between the first lateral portion and the box body. It allows the first lateral portion to rotate and open the dust extraction port while maintaining a controlled connection that prevents complete detachment, thus protecting internal components from pollution while enabling easy pollutant removal.
3Ease of operation
If the lower lid is rotatable to enable easy opening, then the ease of operation improves, but the structural complexity increases
Solution Approach 1:
The lid is segmented into two lateral portions with different functions. The first lateral portion contains the rotation mechanism for opening, while the second lateral portion remains fixed and connected to the box body. This segmentation isolates the rotational complexity to only the necessary portion, minimizing overall structural complexity while achieving easy opening operation.
Solution Approach 2:
The first lateral portion is designed to rotate around a rotation axis, providing dynamic opening capability. This localized dynamic design allows the lid to open easily without requiring the entire lid assembly to be complex or detachable, maintaining simplicity in other areas of the structure.

AI summary
Embodiments can provide a dust collection box and a robot vacuum cleaner. The dust collection box includes a box body and a lower lid. The box body defines a dust extraction port in the bottom thereof. The lower lid includes a first lateral portion and a second lateral portion opposite to each other. The first lateral portion is rotatably connected with the box body to enable the lower lid to open or close the dust extraction port. When the lower lid closes the dust extraction port, the second lateral portion is snap-fitted with the box body through a first snap structure.
