Hi, my name is Jonathan Ulloa. I am a 23-year-old born and raised in Scarborough, Ontario. I have a strong passion for cars, photography, sports, and video games. I am always learning new and different programs that would enhance my skill set. The past four years have taught me many skills and different areas to explore in for the future, and I have learned a lot about my self at that time. Some of the design philosophy I have taken away that is important to me is to understand who you are designing for and having the proper research as well as taking inspiration from many different areas to develop any design that is appropriate to the task.
This thesis proposal investigates the safety, ergonomics, and comfort of movable aerial platforms for the perspective of the user and how they interact with them daily. Current aerial work platforms such as boom lifts and scissor lifts tend to be unstable over certain heights, as well as getting stuck in different terrains. Additionally, there have been fatalities for the user and others working around such as, falling off these machines or not using them properly and getting crushed by one. This thesis purpose is an in-depth study of human interaction with the current products that are out in the market while gathering data through a variety of ways, such as interviews with the users, observation of how they interact with the product, and surveys asking general questions about their interactions. A one-to-one scale ergonomics model is built to see how they used to examine the 5th percentile person and the 95th percentile person interact to understand the full-bodied interactions and the solution. These results were used to design the next generation of aerial work platforms. This new design helps increase the safety, ergonomics, and comfort for the user.
Enhancement of Human Lifestyle
Raizex enhances human interaction innovatively and safely of doing multiple tasks. The user ends up working on an aerial lift for an extended period, and that would include the number of times the whole lift would be needed to move whether up and down or changing the position.
It also depends on the user is using a boom loft or as a scissor lift. Raizex helps with any downtime needed to move as well, giving more needed space for the user to be able to move around. With the ability to move in an X-Y axis on any wall as well as the ample workspace that would give them space to take the material up with them without taking away from the given workspace. As well as adding additional storage at the bottom.
Raizex provides a full-body human interaction design for the user. From everything from the ladder to enter the basket to the position of the doors.
As well as having a control panel that can be used for operating the Raizex when it comes to moving if to and from different locations, and when the basket is up in the air. Having the ability of the controls being able to do two tasks at different times helps with space as well as having an actual area just for controlling the whole lift.
Human Factors and Ergonomics
Raizex is designed for the ergonomics of the 95th percentile man and the 5th percentile woman. The controls are at a comfortable height for all users compared to any other boom and scissor lift, where they tend to be off to the side or too low.
As well the entire flooring is padded to endure when the users are standing for extended amounts of time, that they do not strain themselves. Not to mention that the harness bar goes up and down for a more comfortable reach, and the users do not have to bend down to attach their lanyards to the ground. Instead, the user can attach if at a higher point, then swing the bar down, and the bar would lock into place to ensure that it does not move at all.
Raizex incorporates sustainability in all aspects of site design. The majority of the body would be made from steel for the extenders and the basket.
At the same time, the hybrid engine would be enclosed in a plastic exterior protecting it and the hydraulics. The entire system would be running off a hybrid system that allows it to use electric power when it is not being used in any demanding task, and the engine would start up when the batteries would be running low. There are electric motors at each wheel to give the most amount of power towards the wheels.
