Personalized Helmet Design

The focus of the project was to demonstrate our ability to use CAD software, specifically Onshape and Fusion 360, in designing and modeling the helmet. Initially, each group member worked on their own individual helmet design, exploring different ideas and concepts. Afterward, we collaborated to create a final, personalized group design.

For our group's design, we decided to make a bright helmet to stand out on the track and increase visibility. We also designed the helmet with a clear glass visor for optimal visibility and a strong, hard outer shell for maximum protection. Throughout the process, we conducted extensive research into safety features and worked to ensure that our design met all the necessary safety tests.

Concepts

Friction: a force that resists motion when two objects or surfaces come in contact.

Kinetic Friction: (or dynamic friction) occurs when two objects are moving relative to each other and rub together (like a sled on the ground).

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. 

Reflection

Collaboration was a strong suit for our team. We began by discussing the project and each member shared which part of the helmet design they were most interested in. This allowed us to break up the work efficiently, with each person focusing on a section they felt most confident in. For example, Cole took the lead in researching safety standards and materials, and focused on creating the 3D models while I worked on the sketches and design explanation. This division of labor helped us complete the project smoothly and on time. Everyone contributed their skills, ensuring that we all played an integral role in bringing the project together.

However, an area for improvement was communication. When we split off to work on our individual sections, we didn't always discuss our specific design choices in detail. As a result, some of our sections didn’t flow as seamlessly as we had hoped. Luckily, we recognized this issue early on and were able to adjust by revising our design elements to make everything fit together better. In the future, it would be beneficial to have more regular check-ins and discussions throughout the process to make sure everyone's work is aligned.
