Overview for The MODEL I
Introducing the Model I, the modern update of Henry Ford's classic Model T Ford.
Just as the Model T's iconic design was ideal for the operating conditions and needs of 1908 America, the Model-I is also ideal for the 2018 Island EV Challenge conditions and needs.
Like the Model T, the Model I is designed for rough, unpaved, and unimproved roads - often flooded - as well as rely on very basic and unreliable island electrical grid infrastructure. Also like the Model-T, the Model-I is designed for the frugal islander who needs a vehicle that can "multi-task" for many uses and do so at minimal cost.
With very similar operating goals, it is no wonder the Model-I follows the Model T's very successful classic form.
Large diameter and relatively narrow wheels and tires give the Model-I the ability to overcome large road ruts, obstacles, and ford streams with high ground clearance. While the Model-I has a relatively small footprint, it is still large enough to carry six (6) occupants and their cargo.
Finally while lightly built for low cost of purchase and operation (35 MPH max), the Model I is also durably built. All design attributes the Model T pioneered.
The Model-I updates the Model T with a very modern all-wheel drive (AWD) and all-wheel steering (AWS) electric vehicle (EV) system. Electric hub motors provide direct motive power to each wheel for utmost simplicity.
Further simplification is the Model T's single joystick controller via drive-by-wire and steer-by-wire operation.
The joystick wire-controlled AWS and AWD operation is via the identical front and back powertrain "trucks." Packing all the control and power systems in each truck has several advantages.
One, it allows for greatly simplfied construction and packaging. Two, manufacturing costs are reduced due to the modular nature of the Model-I. And three, the trucks can be further suspended to allow the Model-I to emulate the Model-T's incredible twisting suspension that was key to it's incredible off-road performance.
Finally, modular AWD/AWS powertrain trucks greatly simplfy the service and supply infrastructure since they (along with their associated control and instrumentation components) and the traction batteries (located on the floor) are the only components that must be imported to the island.
Utilizing the trucks to simplify construction, the high boxy Model I body can be supplied several ways. One, they can be imported. Two, they can be 3-D printed on the island. And three, the bodies can even be hand-made with local materials (i.e. - wood).
09/20/18 - This is my first official submission to meet the "Valid" requirements. Hopefully it will meet it. I may still tweak the entry before the final deadline but this submission should be 90% of the entry. Note that I submitted a Solid Edge CAD zip file of my entry. However, one of the *.par files would not zip correctly so I uploaded it separately. Adding that file to the rest of the unzipped CAD files should make the Solid Edge model work.
09/22/18 - Added two additional slides to presentation and PDF.
