Abstract
Most of the doors are designed to close automatically or to be locked against closer at only one position, which is the full opening. In this work, the team focuses on the doors that have a hydraulic closer mechanism with the aim of locking the door against closing at any position. Our product adopts an electrical button to activate and another to deactivate. The door when being held at any position can open freely but instead of closing, it will return to the same position. Main market will be construction companies and door accessories stores. As an initial market, the team is looking to adapt the doors in institutional and governmental buildings. The team is expecting the product to have 50% gross margin and be introduced at first quarter 2020.
