Week #2 - Journal

Ideation

Tell us about your assignment's idea for this week. Why do you care about this idea? What inspired you? (Please include images or links to sources of inspiration)

I improvised the entire thing during the hands-on Minds-on activity. I wanted to create something that would allow me, for example, to watch a movie on my phone

The plan when designing on Fusion360 was to make it less of a total failure because:

1. It used too much cardboard (my instructor, Ahmed Khaled, made the first remark that I had unintentionally designed a television holder)

2. the phone didn't have any support (my phone fell halfway through the prototype showcase, and I couldn't put it back in the area I cut for it because it didn't fit anymore).

So, I looked for similar designs and came up with these.

Tool Chain

Which software/machines/materials did you use in the assignment? Why?

I used Fusion 360 for the design process, and to export the files as DXF
I used LaserCAD software to prepare the mobile holder for laser cutting.
I fabricated it with a Malky ML64 CO2 Laser Cutter machine.
3mm Wood Sheet
Screws and nuts were used to hold the mobile holder together.
Then I used CorelDraw to fix some lines before printing

Design/Preparation Process

Explain the design and/or preparation process of your assignment. How did you use the tool or software to design and/or prepare your assignment before fabrication/implementation?

I measured the dimensions of my phone and design based on them
Using the Line Tool I made several lines
Then I constrained the edges to be perpendicular
For the legs part, I created a line and used the mirror tool around it
Then I extruded the parts to be 3mm, the same thickness as the Wood sheet
Then I assembled the parts using assemble tool
Then I edited the appearance and choose Cherry Wood.
After final modifications, I right-clicked the components and exported each component file as DXF.

Then I used LaserCad to prepare the design to be cut, and I removed all construction lines and unnecessary lines.

Some of the lines were misaligned, and some sections had to be cut; the lab specialist advised me to use CorelDraw to correct them.

Then I saved the DXF file and opened it in LaserCad again, after which I downloaded the design to the machine after adjusting the settings.

Development/Implementation Process

Explain the development/implementation process of your assignment. How did you use the machine/tool to manufacture or implement the design of your assignment?

I used LaserCad and CorelDRAW to prepare the design. and set the cutter settings to:

Mode: Cut
Max Power: 95
Min Power: 90
Speed: 4mm/s

The estimated work time on LaserCad was 12:00 minutes

I downloaded the design and adjusted the nozzle, and set the origin.
Then I placed the wood sheet and drew a box, then adjusted the sheet again
I closed the lid and clicked the start button.

The actual process took exactly 12:34 minutes.

After it was done, I opened the lid and assembled the part using only the joints without the screw and nuts.

Then I used 3mm screws to put it all together.

Final

Community of Learning

Did you ask for feedback? What are the ideas that others have contributed or suggested? What was someone else’s idea that you built upon? How did you help your peers? How did your peers help you?

During the end-of-week session, I was confused by the dimensions and didn't know where to begin when designing the rocking chair. Because I am easily overwhelmed, the instructor, Ahmed Khaled, suggested that we draw the outline first, then fix the dimensions and constraints.

That was life-saving.

Overcoming Challenges

When you got stuck, what/who did you turn to? At what point did you have to pause to research or learn more before moving on? What are some mistakes, pitfalls, or challenges that others can avoid if they were doing this assignment?

I had a creative block while conceptualizing the design, I had to watch many tutorials on people doing similar ideas. I loved how everyone had slightly different approaches to design, especially this, and how other designers would modify the design after they assemble the parts using 3D modeling like filet and chamfer.

I made this design multiple times and the dimensions wouldn't work. Two approaches I found online worked for me:

Parametric Design (didn't make it in the end because, while it made sense, it didn't solve my problem of determining which side is which).
After extruding one part, use the Project feature on the sketches (which I did for my final design)

In addition, I experimented with Arabesque on my own. And discovered this blog:

Final Project

How can you use the skills and knowledge that you've acquired this week in your final project?

I enjoyed designing while keeping some constraints and parameters in mind, in this case, the phone dimensions and the requirement for T slots and joints.

This will allow me, hopefully, to better design the prototype for the final project.

WOW!

What is the coolest thing that you've learned this week? What is something that you will never forget from this week?

Learning How to Sketch an Arabesque, a car, and a phone holder !!

The Arabesque sketch was intriguing because I never understood how these patterns were made in the first place. And also I really love the phone holder I designed :)
