Solution Overview
Problem
Pets left alone at home often experience anxiety and reduced physical activity, leading to potential health issues, and owners face discomfort in leaving their pets unsupervised.
Innovation Solution
A pet care system comprising a mobile robot and wearable device using Ultra-wideband communication to track the pet's movement and distance, allowing the robot to autonomously adjust its motion and provide rewards, ensuring the pet's physical and mental health is maintained even when the owner is absent.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a pet is left alone at home, then the owner's convenience is improved, but the pet's psychological stability and physical activity deteriorate
Solution Approach 1:
A mobile robot acts as an intermediary between the owner and the pet. The robot is equipped with sensors to detect the pet's state, communication circuits to transmit data to the owner's terminal, and can provide stimulation to the pet through sounds or movements, thereby maintaining the pet's well-being while the owner is away
Solution Approach 2:
The system enables the pet to receive care services automatically without direct owner intervention. The mobile robot autonomously monitors the pet's condition, tracks its movements, and provides stimulation when needed, creating a self-service care mechanism that operates independently
2Productivity
If a mobile robot follows the pet, then the pet's physical activity is improved, but the device complexity increases
Solution Approach 1:
The mobile robot is designed with multi-functionality to handle various tasks: it has sensors for detecting the pet's state, communication circuits for data transmission, speakers for providing auditory stimulation, and mobility components for following the pet. This consolidation of multiple functions into a single device reduces overall system complexity
Solution Approach 2:
The patent replaces complex mechanical monitoring systems with electronic sensors and communication circuits. Instead of mechanical means to track and monitor the pet, the system uses electronic signal processing and wireless communication, simplifying the mechanical complexity while enhancing functional capabilities
3Reliability
If the robot uses multiple communication methods, then the communication reliability is improved, but the device complexity increases
Solution Approach 1:
The system employs multiple communication methods (first communication method for general data transmission and second communication method for specific events) to adapt to different communication scenarios. By changing communication parameters and methods based on the situation, the system achieves reliable communication while managing complexity through contextual selection rather than simultaneous implementation of all methods
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively induces movement and provides rewards to pets, improving their physical and mental health, maintains pet interest, and allows for efficient pet care without user intervention, with easy maintenance through a charging station.
Implementation Method 1
a first communication circuit configured to transmit a search signal through a first communication method and receive a response signal corresponding to the search signal from a wearable device
Implementation Method 2
a wearable device including a sensor configured to transmit a response signal through the first communication method in response to the search signal
Data Source
AI summary
A pet care system includes a mobile robot comprising a first communication circuit configured to transmit a search signal through a first communication method and a second communication circuit configured to transmit event occurrence information through a second communication method different from the first communication method. The system includes a wearable device including a sensor configured to transmit a response signal through the first communication method in response to the search signal. The system includes a station comprising an operation dispenser configured to perform a predetermined operation based on the reception of the event occurrence information. The mobile robot further comprises a processor configured to determine a moving direction of the mobile robot based on the response signal received from the wearable device.
