Pet Fence Transmitter Using UWB for Zone Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pet electric fence systems only prevent pets from escaping by forming a virtual fence range based on radio waves, but they do not effectively restrict pets from entering prohibited areas, limiting their applicability.
Innovation Solution
An electronic fence device and system that includes a transmitter to preset a fence range or restricted range, and at least one receiver worn by the pet, using UWB signals to accurately monitor the pet's location in real time and provide warnings when the pet exceeds the fence range or enters a restricted area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If radio waves are used to form a virtual fence range, then the pet can be prevented from escaping, but the pet can still enter restricted areas and destroy objects
Solution Approach 1:
The fence range is segmented into two distinct types: a first fence range (no-entry zone) and a second fence range (warning zone). Each range has different warning mechanisms and enforcement rules, allowing the system to provide granular control over pet movement and respond differently to various spatial zones.
Solution Approach 2:
Different regions of the fence range are assigned different properties and warning methods. The first fence range uses one type of warning mechanism while the second fence range uses another, allowing tailored responses for different spatial locations based on their specific requirements.
2Ease of operation
If a single virtual fence range is used, then the system is simple to operate, but it cannot provide differentiated warning mechanisms for different areas
Solution Approach 1:
The fence range is divided into multiple zones with different warning mechanisms, allowing the system to maintain operational simplicity while introducing differentiated control where needed.
Solution Approach 2:
The system dynamically adjusts warning mechanisms based on the pet's location. When the pet enters the first fence range, a first warning mechanism is activated; when entering the second fence range, a second warning mechanism is activated. This dynamic adaptation allows complex functionality to emerge from simple base operations.

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 prevents pets from escaping and entering restricted areas with high accuracy, improving the applicability of electric fence technology by providing a precise and reliable method for monitoring and warning pets.
Implementation Method 1

AI summary
An electronic fence device includes: a transmitter, arranged to preset a fence range or a restricted range; and at least one receiver, configured to be worn on a pet. The transmitter comprises a locating module; each of the at least one receiver comprises a tag module; the locating module and the tag module are configured to exchange measurement signals therebetween to monitor a location of the pet in real time. The transmitter is configured to compare the location of the pet with the fence range or the restricted range; in response to the pet being located out of the fence range or entering the restricted range, the transmitter is configured to provide a feedback to the receiver to give a warning to the pet.
