Solidworks TRAINING

I took on a 2-Day course for Solidworks, a 3D software program used by professionals.

While there, I created many different designs using this program. Below are a few of the objects I created.

SKETCH Review

These are two sketches I did during the two week e-learning period. The one on the left has multiple different shapes with one-point perspective and shading. The one on the right is an illusion of a floating 3D capital A.

New Project

Today we were given a new project to work on.

Constraints

The constraints for this project are listed here on the paper above.

Benchmarks

These are the benchmarks for our project. These will help us guide us from start to finish.

Research

The purpose of research is to gather ideas to help us form our own ideas and gain an understanding of what is possible for this project.

Volume and Drawing of My design

My design will be made with a 12 x 12 x 1 piece of wood, making the volume 144 cubic inches. This is under the requirement of 150 cubic inches. My form has 8 3 x 12 x 1/2 inch isosceles triangles, but 2 inches is taken off the top of each triangle. There is also one octagon that sits at the end to bounce the sound out through the opening.

My form is an octagonal cone, where the phone sits at the back. I chose it b/c it looks like a Gramophone

My Form

My form is an octagonal cone, where the phone sits at the back. I chose it b/c it looks like a Gramophone

Major Changes

I was looking back at my design and saw a major problem. I noticed that the phone isn't able to fit inside of my cone. Not only that, because we are confined to our homes, we must 3D our project and the limits of the 3D printer is that the pieces cannot be bigger than 6 inches. So after some more brainstorming I came up with my current design.

the 3D Prototyping Process

How we went through with the making of our project:

Research

Geometric Motion Lamp

This is the lamp we are making in our eng pathway.

Project Constraints

These is the list of constraints. We need to meet all the constraints to complete this project successfully.

Geometric Motion lamp PROTOTYPE

This is my cardboard prototype of my lamp. To get to this point, we have practiced making cardboard cubes to get good at measuring and thinking about materials thickness. We are also practicing Single point perspective Sketching so that we can communicate our ideas of our forms. Finally we drew up a plan that we knew would meet the constraints and then we made it.

My GEOMETRIC Design Final PROTOTYPE

This is my final geometric design prototype with all the lights fully functional

DETERMINING the Joint angles

In this benchmark, we had to do math to figure out which angle we needed to sand our lamp to assemble it.

Dry Fitting

I dry fitted my arrow together but the bottom pieces did not fit properly. After talking with Mr.Wilson, he determined that I should build my project and sand it down once it it is glued.

Copper Wire

After dry-fitting my pieces, I added the copper wire. To make sure the connection reached all the pieces I added orange wire to each space.

Installing LiGhts

I finished installing my lights and got each of them to light up on my wooden model.

Cord Outlet

This is where the cord will exit. The bottom is open for access

Arduino Placement

My arduino is placed near the middle of my arrow so the wire coming out can stand without and difficulty.

Access Points

I have a hole cut out in the bottom that can not be seen from the front so I can adjust anything needed. I used hot glue and strings to attach the top on as a latch so it is also an access point.

MY FINISHED PROJECTS WITH THE WORKING code

S: In this project we incorporated various aspects of Physics. We created a functional circuit and to do this we learned about circuits. We also know that each of our lights emits a different wavelength of light.

Inkscapes Model

T: In this project we used technology for many different aspects. We created original prototypes using paper, hot glue guns and cardboard. After many edits, we created our files of our pieces to be laser cut in SolidWorks CAD Software. From there we were able to convert the files to SVG using Inkscapes and then we cut them out using the Glowforge Laser Cutter. Throughout the total project we used LEDs and arduinos for programming the LEDs in succession.

Solidworks model

E: In this projects we made lots of edits and changes that lead to the eventual completion of our lamp. Also we made our shapes of our lamps very unique. My shape in particular, a chevron, is not seen very often and it is even more difficult to find at this angle because of the center of gravity is not centered at a way it can without support.

A: This project incorporated has a lot of artistic skill. The artistic design process is the same as the engineering design process however it is less constrained. Project we did a lot of practicing with a single point perspective. We used these skills to allow us to envision what our project looks like from different angles.

M: This project has a lot of Mathematical elements. For example, to find the angle at which we were supposed to sand our lamps at for better gluing, we had to use math and a protractor. Also we needed to find a scale size at which out shape could fit within a 12x12 piece of plywood and if it could fit all the necessary electronics.

12 x 12 piece

How I met the constraints

My project is freestanding because the plank on the bottom shifts the center of gravity. It is an interesting geometric design because my lamp is a very uncommon shape, also my lamp has only 13 LEDs, fitting within the 8-16 LED constraint. All the electronics fit inside with access points on the top and bottom for easy edits/troubleshooting. The lights move in 3 different patterns that look as if the move along the lamp
