Picture This

Major moves were made this past week! We started narrowing down our potential features and started to finalize our design. The new model features colored stripes in the top left corner, pegs on the body for the snap rings, no button, and a slot that will hold a small picture. When modifying our final product, we encountered many problems that would arise from the manufacturing process. Some of the factors we had to consider included shrinkage, cooling time, undercuts, binding to the mold, and performance. After taking all of these into account, these were our final components with the processes that accompanied them: Injection Molding Camera Body: cylindrical piece; uniform thickness; 10 pegs for the components of the camera front to snap into Snap fits with front components Camera Front Top: cylindrical piece; not a complete circle; only 140.4 degrees; hole in the center of the outer diameter for the lens; extruded face with rounded edges and a filet for the front fa

This week, we began designing our yo-yo! From our brainstorming last week, we decided to move forward with the polaroid camera/instagram theme yoyo (henceforth to be known as the Yolaroid). We aimed to find a balance between aesthetics and potential for creativity, and ultimately felt that this yoyo had the best of both. For one, it's striking! And will look especially cool if we can get the colors right. Secondly, there exists a lot of opportunity for creativity. We had a few ideas that could spin out of the idea: "Flash," or an LED to light up as you yo the yo A button that releases a "polaroid picture" (Picture of what? Stay tuned.) A clear through hole to act as the lense For this week, we designed our yoyo based on idea #2. We like this one the best, but we'll revisit the other ideas if we have more time and/or want to get fancier later.  Our design features the following parts: Camera rear body (injection molded) Camera front snap rin

Choosing an idea

This past Friday we had our first team meeting! We each came up with five to ten potential yo-yo designs and pitched it to the group. Here were some of the original ideas and sketches we made! To help us narrow down our decisions, we came up with some design criteria that were important to us. We decided that our yo-yo needed to be creative, exciting, functional, and feasible. Using our design criteria and through some difficult voting, we finally narrowed it down to four. Amazingly and by sheer luck, each of us had an idea picked to be in the final four, which made it easy to split up the work! Over the weekend, each of us designed our own idea. Here were the four finalists!   Works of art if you ask me. Finally, today, we chose the design we would be making for the rest of the semester. We really like all of the ideas and ultimately voted (via the very scientific Facebook Messenger poll) with the polaroid because it was creative but hopefully still straigh

Hello World!

Hello everyone and welcome to our blog! We are undergraduate course 2 students in MIT’s 2.008: Design and Manufacturing II. This semester we will be manufacturing 50 yo-yos (hopefully without breaking the bank). We will be learning about various manufacturing methods throughout this semester as we design our yo-yos and molds and then fabricate them using our new knowledge of thermoforming and injection molding. We are excited to get started and to share our ideas and process with you throughout this semester! Here is our team picture: From left to right: Lisa Gardner, Diann Huynh, Srimayi Tenali, and Albert Go.
