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 cleaning, 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 is not promptly cleaned
Solution Approach 1:
The system performs preliminary detection of pet activity using sensors (weight sensors, motion sensors, cameras) before debris is scattered. When pet activity is detected, the cleaning robot is immediately dispatched to the pet area to clean before debris tracking occurs, preventing the problem rather than reacting to it.
Solution Approach 2:
The system implements a feedback loop where sensors continuously monitor pet areas for activity indicators (weight changes, motion, camera detection). When debris or activity is detected, the system automatically triggers a cleaning mission, creating a closed-loop responsive cleaning system that adapts to real-time conditions.
2Reliability
If sensors continuously monitor pet areas for pet activity, then cleaning response time is improved, but energy consumption increases
Solution Approach 1:
Instead of continuous monitoring, the system uses periodic detection triggered by specific events. Sensors are activated when pet activity is detected (weight sensor triggers, motion detected), and the cleaning robot navigates to the area only when needed. This event-driven approach maintains high detection reliability while significantly reducing energy consumption compared to continuous operation.
3Productivity
If the cleaning robot uses high vacuum power to clean pet areas, then debris removal efficiency is improved, but debris scattering increases
Solution Approach 1:
The system performs preliminary detection and navigation to the pet area before initiating high-power vacuuming. The robot first locates the exact position of pet debris using sensors and camera identification, then positions itself optimally before activating high vacuum power. This preliminary positioning prevents debris scattering by ensuring the vacuum intake is already in the correct location.
Solution Approach 2:
The system applies high vacuum power locally only at the specific pet area where debris is detected, rather than using high power throughout the entire cleaning path. The vacuum power is concentrated at the debris location identified by sensors and camera, maximizing removal efficiency while minimizing the area affected by potential scattering.
