 ''Gate 1'': Project Planning – During the project planning phase, a project management proposal was drafted to assess our team’s strengths and weaknesses and to create formal procedures for handling team issues and conflicts that might arise.we assessed our team, established roles, researched our product, and documented an assessment of our product before dissecting it, to make predictions of what we would learn in future gates. We also made accurate predictions of ease of assembly.An initial dissection procedure was created by studying the visible components about what interior components might lie beneath the snow-blower casing based on our initial research and understanding of two-cycle gas engines.  The snow-blower’s usage and complexity were studied in detail and a product alternative profile was created to demonstrate some other options that achieve the same product function of snow removal.
-''Gate 2'': Product Dissection – In the product dissection phase, the snow-blower was dismantled into individual components.  The disassembly process was thoroughly documented and each step was assigned a difficulty rating. We found that the best way to perform this task was to have two people document the disassembly, one wrote each step while the other took pictures and labeled the parts to be put in containers.  The other two members then worked together to find the necessary tools and removed the fasteners that hold the snow-blower components together.  This recipe was found to be highly successful and was repeated in the product reassembly, Gate 4.

 ''Gate 3'': Product Analysis – In the product analysis phase, the individual components of the snow-blower were analyzed for part geometry, manufacturing methods, and complexity of the geometry and interactions with other components.  By performing these studies, the manufacturing processes were reinforced and conclusions were made that connected the Four Factors to the design of the significant components.  In this gate, three important components of the engine were modeled using Autodesk Inventor.  Additionally, an Engineering Analysis was performed to calculate the convection of heat from the engine heat sink to the surrounding environment.  This information could be used to help drive possible redesigns of the engine block and the surrounding exterior casings.

-This project demonstrates an application of engineering principles learned in class by our group to analyze a practical product.  Throughout the project’s completion, a myriad of skills covered in the Intro to Mechanical Engineering Principles class curriculum were used in each deliverable.  This fact can be seen from the analysis problems applied to the Snow-blower’s design up to the assigning of manufacturing methods to each part on the product.  Finally, this project also increased each group member’s ability to work as a team.  This was due to the fact that as frequent challenges presented themselves, we were forced to adapt and work collectively to overcome them.
