Device to lift a kayak onto a standard car carrier

The Horizon Science Academy Cleveland High School InvenTeam invented a device to lift a kayak from the ground onto a roof carrier on top of a car. The device is powered by a standard 12 V car outlet which lifts the kayak onto the roof rack in under 30 seconds. The only human power required is to strap the hoist lines onto the kayak which are secured with Velcro. This invention makes it possible for people who cannot lift their kayak to continue participating in an activity they enjoy.

It’s spring! Currently, we focused on building our prototype and making changes to the design to make sure our invention moves smoothly. We ran into a minor problem with a shipping company but with a little communication with the company, it was taken care of. The biggest obstacle this month was finding strong/heavy duty hinges that fit on our contraption, we worked it out eventually. As we come closer and closer to EurekaFest our motivation grows. If we keep working like this, we may be finished with the prototype by mid-May.

There has been so much happening in the last few weeks that it has all been a blur.  As we see the days tick off the calendar the reality of it all is setting in.  The frustration is real, and often, but the "Eureka" moments more than make up for them.  Our team is running like a well oiled (and patented) machine, and, as we head into winter break for a well deserved rest, we are looking forward to getting back together to see this project to completion.  One of the highlights of the month is that we got to meet Dr. Estabrooks, and she was kind enough to give us some much needed tips and pointers.  We have also been learning about hydraulics and linear actuators and how we can best utilize them in our prototype.  Like we said before: So much to do!

Since the beginning of October, the HSA InvenTeam has been researching ideal materials, existent patents, and the average specifications of car roofs and roof racks.
