    Boat lift
    (University of New Brunswick, 2017) Donovan, Andrew; Whitrow, Jeffery; Gear, William
    The intent of this report is to document the work of this group that has been done throughout the year with regards to the boat lift project. To begin this project time was spent researching various existing designs and doing background research. This was done to gain an understanding of common designs and practice. Background research was done to gain knowledge of preexisting designs and methods that will help formulate a design that is unique from existing designs, and without this background research it would be much more difficult to create a design or concept. It could also be possible to unknowingly copy a preexisting design without research. After background research was done and a baseline of knowledge on the topic was created then multiple concepts were created that share some common aspects of existing designs and incorporate other aspect unique to this design group. These multiple design concepts were rated and their feasibility and appropriateness were considered. Using a decision matrix it was determined which design concept was best suited for this application and should be pursued further. Using this method of selection means that the chosen concept is guaranteed to meet the design criteria and best meet the client’s needs. Since the concept design had been finalized there have been many hours spent optimizing the specific details of the design. This also include the analysis which covers all crucial areas of the design such as the cable lifting system, the frames and links, and the various joints and pulleys that will be used to manipulate the boat lift. The analysis is used to observe the kinematics, forces, and stresses acting on the structure. The purpose is to focus on building a device that is designed to have an optimized lifespan as well as function for as long as possible without fault, while also considering cost and availability of materials or components. At the point of this report being submitted the analysis has almost been finished, with only a few updates required for future changes to the design. The CAD for the boatlift has been completed and many engineered drawings may be found in this report, along with the analysis completed on the components to ensure the boat lift will be able to withstand the environment it is subjected to.
