The Objective

Develop a Dog Collar that is able to easily adjust to allow the perfect fit around the animals neck.  The resulting product was to be robust and have a high breaking strain to suit the strongest of dogs.

The Solution

A cam and ratchet system was utilised to allow for infinite settings without the need for a "pin in hole" locking arrangement seen on existing collars and belts. 


As existing cam systems only allow for one way operation and could have caused a choking hazard on dogs, a new Bi-Cam technology was required.  This was Invented for the client by F3 and is seen as a 100 year change technology in the collar, belt and ratchet industries. 


The resulting product was built around this new ratchet system in a streamlined and easy to use solution, which allows the collar to be accurately fitted to the pets neck at the push of a button, has an easy fit guide for the strap, is robust and locks securely around the dogs neck with a double action Bi-Cam ratchet.

The technology was granted a full patent based on the twin cam technology that F3 Invented.
