Break It Apart!
Evidence of Work
The goal of this activity was to practice our free-hand conceptual sketching abilities and the skill set it takes to fully observe every part of a mechanism and understand how it works. The first step was to bring in a mechanical object that could be taken apart easily with simple tools. We also had to bring the correct tools to disassemble the objects. The next step was to keep track of all the parts as you take it apart and draw a detailed "exploded view" with labels and dimensions. The next step was to draw a flow chart of how you believe the mechanism works. The final step was to write down all questions that you want to research on your object.
As my object, I chose an old remote controlled car that no longer works. It is very complex as the circuit board has to control the steering, speed, braking, reversing, and has to wirelessly connect to the remote (not included in this project). I did a page of a sketch with questions at the bottom.

Conceptual sketch-Â a simple sketch that illustrates the main aspects of a concept or system labeled with the process that are happening, the components involved, and the relationships between the features.
Engineering Design Cycle- ask, research, brainstorm, plan, create, test, and improve.
Technical/Engineering Sketch- a three-dimensional drawing on a two-dimensional paper or computer screen. Also know as a projection. Could be Isometric, Axonometric, Oblique, Perspective, or Orthographic.
Engineer- a person who designs, builds, or maintains engines, machines, or public works.
Exploded View- a specific view of a mechanism that is pulled apart so that you can see the way it is put together as well as the way it works.
Mechanical Systems- the relationship between two or more components that accomplish one goal together
Reflection
I succeeded in the exploded view of my object. I made sure to show how the wheels were attached, and how the pieces went together. I understand that I could have done a more complete job, but I had less time than I thought I would have, and so it was rushed. I felt that I understood and executed the preperation and material collecting well. I made sure to bring all of the necessary components within the deadline.
I could have studied the circuit board more, and worked on a flow chart. I did not manage my time well, and learned the tough lesson that class time is very precious and every minute of it should be used efficiently and with precision. In order to have less homework or outside of class work in this class, I need to really work on staying focused.
