The Ultimate Dog Collar The Team Faculty Advisor Dr. Patrick Donohoe Daniel Stevenson (Electrical Engineering) Kaytan Mills (Electrical Engineering) Team Leader Kevin Quave (Electrical Engineering) Kyle Kilburn (Electrical Engineering) Outline Problem Solution Constraints Technical Practical System Overview Design Changes System Testing Remaining Tasks Q&A Incessant barking Jumping on visitors Using the restroom inside (assuming it is an indoor/outdoor dog) Tugging at the leash Running away Digging in the garden Problem Dog owners are beset by numerous difficulties [1] Market Solutions The Shock Collar Allows users to discipline their dog easily and quickly $30 - $260 Invisible Fence Shocks the dog via a shocking collar when it tries to cross the boundary $150 - $350 Dog Doors Allows the dog to enter or exit at its leisure [2][3] $170 - $1300 Our Solution Dog Collar Training Remote Invisible Fence Dog Door Our solution combines the three aforementioned systems into one elegant design. This system uses a single shock collar for all three applications diminishing the need for multiple collars. Technical Constraints NameDescription Battery Life The battery life of the collar must be at least thirty six hours and the battery life of the remote must be at least six months. Operating Range The remote must have an unobstructed operating range of at least 50 feet. Response Time The collar must respond to the training remote within one second. Size The collar dimensions must be smaller than 6x4x4 inches. Weight The weight of the collar must not exceed one pound. Practical Constraints The Ultimate Dog Collar must not cause excessive pain to the dog Ethical [4] Practical Constraints Practical Constraints Ethical Vibrating motors are used over the more common shock Avoids the negative reputation of shock Has the same desired effect as the shock No pain Practical Constraints The collar must be tough enough to withstand the potentially rough behavior of dogs. Rolling Jumping Running The collar must be able to handle normal weather conditions.
