Solution Overview
Problem
Existing cleaning bins for autonomous cleaning robots are not easily detachable, often require manual emptying, and may be prone to corrosion due to exposed metallic components.
Innovation Solution
A pivotable cleaning bin design with a prefilter and filter orientation that allows for one-handed removal and installation, lacks exposed metallic components, and can be washed without risk of corrosion, featuring a bin attachment hook and latch mechanism for seamless integration with the robot.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a cleaning bin is designed with exposed metallic components, then structural strength is improved, but corrosion resistance deteriorates
Solution Approach 1:
The cleaning bin combines metallic components (for structural strength) with non-metallic components such as plastic housing and coating layers (for corrosion resistance). This composite structure allows the bin to maintain mechanical strength while protecting against corrosion through the protective non-metallic layers.
2Reliability
If a cleaning bin is designed with complex attachment mechanisms, then connection reliability is improved, but ease of operation deteriorates
Solution Approach 1:
The attachment mechanism is divided into separate modular components including attachment arms, latches, and corresponding receptacles. This segmentation allows each component to be independently optimized for both secure connection and easy release, enabling reliable attachment while maintaining user-friendly operation.
3Volume of moving object
If a cleaning bin has large volume, then debris capacity is improved, but device complexity deteriorates
Solution Approach 1:
The cleaning bin employs a nested structure where the debris chamber is positioned within the overall bin assembly, with the prefilter integrated into the chamber walls and the filter assembly nested within the housing. This nesting approach maximizes debris capacity while minimizing structural complexity and space requirements.

AI summary
A cleaning bin mountable to an autonomous cleaning robot operable to receive debris from a floor surface includes an inlet positioned between lateral sides of the cleaning bin and an outlet configured to connect to a vacuum assembly, the vacuum assembly operable to direct an airflow from the inlet of the cleaning bin to the outlet of the cleaning bin. The cleaning bin also includes a debris chamber to receive debris from the airflow, an airflow chamber separated from the debris chamber by a prefilter, the prefilter forming at least a portion of a top surface of the debris chamber and at least a portion of a bottom surface of the airflow chamber, and a filter socket configured to receive a filter and provide the airflow to through the filter to the outlet of the cleaning bin, wherein the filter is positioned substantially perpendicular to the prefilter when the filter is positioned in the filter socket.
