Dual-Portion Debris Collection Device for Autonomous Cleaning Robots
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing debris collection systems for autonomous cleaning robots are inefficient in handling both larger and smaller debris simultaneously and often require manual handling of collected debris, posing a risk to users.
Innovation Solution
A debris collection device comprising a cleaning pad portion and a vacuum bag portion that work in conjunction with the autonomous cleaning robot's vacuum assembly to collect larger debris in the vacuum bag and smaller debris on the cleaning pad, allowing for simultaneous collection and easy ejection of the device after cleaning, thereby minimizing user contact with debris.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single debris collection system is used, then the device complexity is reduced, but the cleaning efficiency and ability to handle different debris sizes simultaneously deteriorates
Solution Approach 1:
The debris collection device is divided into two distinct portions: a cleaning pad portion for collecting smaller debris through contact with the floor surface, and a vacuum bag portion for trapping larger debris removed by airflow. This segmentation allows each portion to be optimized for its specific function, enabling simultaneous collection of different debris sizes and improving overall cleaning efficiency without requiring a single complex system
2Object-affected harmful factors
If manual handling of collected debris is required, then the device complexity is reduced, but user safety deteriorates due to direct contact with debris
Solution Approach 1:
The entire debris collection device comprising both the cleaning pad portion and vacuum bag portion is designed to be removable as a single unit from the autonomous cleaning robot. This extraction approach allows users to remove the complete debris collection device without direct contact with the debris contained within, eliminating safety hazards while maintaining operational simplicity
Solution Approach 2:
The vacuum bag portion is positioned within or integrated with the cleaning robot body, and the cleaning pad portion is attached to the vacuum bag portion, creating a nested structure. This nesting allows the entire debris collection assembly to be removed as one unit, enabling users to dispose of debris without direct contact while keeping the system compact during operation
3Quantity of substance
If the vacuum bag portion volume is increased to collect more debris, then the debris collection capacity is improved, but the device dimensions and space requirements worsen
Solution Approach 1:
The vacuum bag portion is designed with a specific volume range (320-1080 mL) that is optimized for collecting larger debris particles. The cleaning pad portion simultaneously handles smaller debris, creating a local quality differentiation where each component is sized and designed for its specific debris size range, maximizing overall collection capacity without requiring excessive total volume
