Autonomous Cleaning Robot Pet Area Detection and Targeted Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cleaning robots lack the ability to autonomously detect and respond to pet activity in pet areas, such as litter boxes, dog doors, and bird cages, leading to inefficient and scattered pet debris cleanup, which burdens pet owners and contributes to household mess.
Innovation Solution
An autonomous cleaning robot equipped with sensors to detect pet activity, a controller to navigate to pet areas, and a cleaning assembly to execute cleaning missions with adjustable vacuum power and cleaning modes, including a two-stage cleaning process to minimize debris scattering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If cleaning robots perform general area cleaning, then overall household cleanliness is improved, but pet debris in specific pet areas accumulates and scatters
Solution Approach 1:
The system employs sensors (cameras, microphones, weight sensors) to detect pet activity and debris in pet areas, providing feedback to the controller. When pet activity or debris is detected, the robot automatically navigates to the pet area and performs targeted cleaning, creating a closed-loop feedback system that resolves the contradiction between general cleaning coverage and specific pet area effectiveness
Solution Approach 2:
The cleaning robot autonomously monitors pet areas using integrated sensors and automatically initiates cleaning missions without human intervention. The system self-manages the detection of pet activity, navigation to pet areas, execution of cleaning tasks, and adjustment of cleaning parameters, enabling self-service operation that maintains both general cleanliness and pet area hygiene
2Reliability
If manual cleaning of pet areas is performed, then pet debris is removed promptly, but pet owners bear the burden of frequent monitoring and cleaning
Solution Approach 1:
The system transfers the monitoring and cleaning tasks from pet owners to the autonomous robot. Sensors continuously monitor pet areas for activity and debris, and the robot automatically navigates and cleans when needed, completely eliminating the need for pet owners to manually monitor or clean pet areas, thus resolving the contradiction between cleaning timeliness and owner workload
Solution Approach 2:
The robot uses sensors to provide continuous feedback on pet area conditions to the controller. When debris or pet activity is detected, the system automatically triggers a cleaning mission, ensuring prompt cleaning response without requiring pet owner involvement in monitoring or decision-making
3Productivity
If high vacuum power is used in pet areas, then pet debris is effectively removed, but pet equipment may be damaged and undesirable scents are not ventilated
Solution Approach 1:
The system dynamically adjusts vacuum power based on real-time sensor feedback from pet areas. The controller modulates the vacuum motor speed according to the type of pet area (litter box, dog door, bird cage) and the amount of debris detected, enabling high power when needed for debris removal while reducing power to prevent equipment damage and manage scent ventilation, thus resolving the contradiction between cleaning efficiency and equipment protection
Solution Approach 2:
The robot applies different cleaning strategies to different pet area types. The system identifies the specific pet area using sensors and camera recognition, then applies locally optimized cleaning parameters - such as lower vacuum power for bird cages to protect equipment, and controlled ventilation for litter boxes to manage scents while removing debris, resolving the contradiction through localized quality adjustment
4Area of stationary object
If side brush is active during pet area cleaning, then debris coverage area is increased, but debris scattering increases
Solution Approach 1:
The system dynamically controls side brush operation based on the cleaning stage and pet area characteristics. The controller activates or deactivates the side brush depending on whether the robot is in approach mode or active cleaning mode, and adjusts brush speed accordingly. This dynamic control enables the side brush to expand cleaning coverage during approach while preventing debris scattering during actual pet area cleaning, resolving the contradiction between coverage area and debris scattering
