OVERVIEW | DESIGN PROCESS | FINAL DESIGN | PROTOTYPE | MEET THE TEAM
Thanks for stopping by to check out Team Rack Em’ Up! We are a team of engineering students who have revolutionized the way gear is loaded onto your vehicle. The Rack em’ Up system is designed to make loading and unloading gear a breeze. When the gear is loaded and secured, the rack can be easily put back on the vehicle with the assistance of gas cylinder struts. When the gear is ready to be unloaded, a two step sliding-pivoting action will safely lower the rack back down with minimal effort. Rack Em’ Up is compatible with a variety of gear including: skis/snowboards, bikes, kayaks, camping gear, and more!
The decision process we used for our design concept was the consensus decision-making method. This process avoids “winners” and “losers” by requiring the group to have a majority vote on the design concept, but for any objections by the minority there are changes made to the design to make it acceptable for the entire group. This process worked very well for our group due to the common goals and thinking between all of our members regarding this project. The decision process began with each member being required to bring their own ideas to the
discussion on how the rack should meet each individual function. Each concept was then discussed by the entire group, breaking them all down into their strengths and weaknesses, so that everyone had an understanding of how each concept could meet the functional requirements. Once everyone had an understanding of the concepts, the two main concepts of a spring loaded system and a gas cylinder system were unanimously agreed upon to be the frontrunners of the design concept. After the consensus process, it was agreed upon that the tilting method powered by a shifting center of gravity was to be investigated. The shifting center of gravity would be powered by a gas cylinder that will run parallel with the roof of the vehicle.
BACK TO TOP
After many iterations of designing, testing, and collaborating with potential customers, our final design has been decided. The images below show what the rack will look like when it’s in the retracted position (left) and the loading position (right). This design enables users to easily load and unload equipment.
The main component of the rack are the gas struts. The gas struts enable the user to handle loads that they would otherwise be unable to handle without the Rack ‘Em Up system.
To ensure that the right material was selected for this design, a SolidWorks simulation was done. This simulation was done with 1020 DOM steel. The results show that this material is a perfect choice for the rack and its low cost will allow us to market our rack for a lower price than our competitors.
Based on the success of the Proof of Concept, we have a full scale prototype that will show the full functionality of the rack. This prototype was built as carefully as possible and will be tested on multiple vehicles under different conditions to ensure it will meet all expectations.
The fabrication process involved a lot of welding and cutting of the steel tubing. Welding the tubes together was done carefully to avoid warping of the steel. The most time consuming process of fabrication was honing and polishing the sliding tube. This interface needs to be as friction-less as possible so that sliding the rack out will be as easy as possible.
