Separable Robotic Vacuum Dustbin for Water-Immersion Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Robotic vacuum cleaners require cumbersome and imprecise manual emptying of dustbins, which can leave behind debris and make servicing of internal components difficult, and do not allow for easy cleaning or immersion in water due to integrated electronics.
Innovation Solution
A separable dustbin design where the motor and impeller are attached with latches, allowing easy removal and immersion in water for cleaning, and improved access for repair and replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the motor and impeller are integrated inside the chassis or connected to the dustbin, then the vacuuming function is maintained, but access to the motor/impeller for repair or servicing becomes difficult
Solution Approach 1:
The dustbin assembly is segmented into separate components: the dustbin itself and the motor/impeller unit. The motor and impeller are attached to the dustbin as a removable unit, allowing the dustbin to be separated from the chassis while maintaining the vacuuming function. This segmentation enables easy access to the motor and impeller for repair or servicing by simply removing the dustbin assembly.
2Ease of manufacture
If electronics are integrated inside the dustbin, then the vacuuming function is maintained, but the dustbin cannot be immersed in water for thorough cleaning
Solution Approach 1:
The electronic components are extracted from the dustbin and placed in the chassis, separating the washable dustbin from the non-washable electronics. The dustbin is designed to be wholly separable from all electronic parts, allowing it to be immersed in water for thorough cleaning without risk of damaging electronic components.
3Productivity
If manual emptying of the dustbin is performed by shaking or brushing, then debris removal is achieved, but small particles remain and become airborne
Solution Approach 1:
The manual mechanical emptying process (shaking or brushing) is replaced with an automated suction system. A suction port is provided in the dustbin, and the motor/impeller unit creates negative pressure to automatically suction out debris, including small particles, through the suction port. This eliminates the need for manual shaking or brushing and prevents small particles from becoming airborne during the emptying process.

AI summary
A removable dustbin for a robotic vacuum that is wholly separable from all electronic parts thereof including a motor unit such that the dustbin, when separated from the electronic parts, may be safely immersed in water for quick and easy cleaning. The dustbin design further facilitates easy access to the motor for convenient servicing and repair.
