Every group was tasked with creating a personalized helmet that meets the basic standard requirements for motorcycle or car helmets. Each group had to create paper sketches of the personalized helmet: Orthogonal, and perspective; create paper designs to decorate the Helmet; a written design explanation of how your helmet meets the safety standards, materials, and possible extra functionalities; a written report of your research; a Digital Portfolio page entitled "Personalized Helmet Design" that includes all written products (research report, design explanation, paper sketches, and 3d models). This project is meant to demonstrate our new skills using CAD software, specifically Onshape and Fusion360. We first created a helmet design individually, then created a personalized one crafted by our group. Our group chose chose to make a helmet that is bright green with a clear glass visor for maximum visibility and a hard outer shell. We did a ton of research on safety features and attempted to make our design pass all of the safety tests. Below is our group's research, design explanation, paper sketches, and 3D models.
This is our helmet. We constructed our 3D model in Fusion 360. We chose to include a bright green outer shell, a small breathing slit to improve breathability, a clear glass visor for visibility, and a visor that doesn't completely cut off air flow so that the driver doesn't overheat.
Acceleration: a change in speed over a period of time; the higher the acceleration, the faster the change in speed. Acceleration is a rate of change of speed; NO change means NO acceleration. If something is moving at constant speed, it is NOT accelerating.
Coefficient of Friction: the measurement of the level of friction embodied in a particular material. The formula is μ = f/N, where μ is the coefficient of friction, f, is the amount of force that resists motion, and N is the normal force.
Crumple Zones: areas of an object designed to deform and crumple in an impact, as a means to absorb the energy of a collision.
Drag: a term used to refer to air resistance or fluid resistance. Friction is one of multiple factors that influence the amount of drag encountered by a body moving through a fluid such as air or water.
Inertia: when an object remains still or moves in a constant direction at a constant speed.
G Force: a force acting on a body as a result of acceleration or gravity, informally described in units of acceleration equal to one g.
Force: causes masses to accelerate; they are influences that cause a change of movement, direction, or shape. When you press on an object, you are exerting a force on it.
Two things our group did well this project was collaboration and conscientious learning. We demonstrated great collaboration because everyone expressed what area of the project they wanted to focus on, and we were able to break up the work efficiently. Each member completed a section of the project that was one of their strengths. This caused our project to get done efficiently and on time. We demonstrated conscientious learning by listening to each other's concerns and ideas and including all ideas in our design. We also managed our time effectively to get our project completed on time.
Two things we could have done better in this project was critical thinking and communication. We could have demonstrated communication better because when we split off to do our separate sections of the project we didn't discuss the specific ideas of what we were doing. This caused issues as our sections ended up not flowing together. Luckily we noticed this issue early on and were able to adjust in time. We also could have worked on critical thinking because the software we used, especially Fusion 360, was very difficult to understand, and we ran into many problems creating our helmet. Problems we were met with were making the helmet hollow, creating a movable visor and vents, and specific design elements that seemed to be impossible. Even though we ran into these problems constantly we thrived in working through it using collaboration and conscientious learning within our team and with our whole class. We worked through the problems and did the best we could with our limited knowledge of the software.
