Mobile Holder Design Inspiration

This week we were asked to design a model of a simple mobile phone holder that rests on a flat surface.

Through the week, I started to search for a design that suits my needs. In fact, I wanted a mobile holder that allows me to flexibly move the mobile phone in different directions while it is holding it. Adding to this, I want it to be in the level of my eyes.

Until I finally found an inspiration for my mobile holder design through this website.

Tool Chain

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

I used "Fusion 360", which is a cloud-based CAD/CAM tool for collaborative product development that combines industrial design, mechanical engineering, and machine tool programming into one software solution. So, it was the best choice for this week assignment 😃.

I also have used 'LaserWork' to adjust the file settings for cutting.

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?

2D Parts Free Hand Sketch

The first step I made in my designing process was analysing the design I chose in order to cut it out into several 2D pieces sketching which will then be assembled to form the holder.

I started to put the dimensions on the different parts respectively and some of the dimensions were standard as that of the T-slot part.

After that, I walked through the videos of designing and made sure that I know all the points that were covered in them. And sure I have tried the exercises again to make sure that I can implement those points that were covered.

Then, I drew each of the parts on the suitable plane.

These are the steps for designing the base,

Choosing the 'x-y' plane for drawing

From the 'create' section , we can choose different shapes options to be used in our design

Selecting the 'ellipse' option, from the 'create' section in order to form the outline shape of the base

For the press fit, I used a 'rectangle' option.

For the screw whole, I used the 'center diameter circle' option.

By pressing (Ctrl+L) as a shortcut for the 'line' option, in order to draw the ellipse central horizontal line.

Changing the central line type into a 'construction line', so it turns to be a dashed line after it was a solid one.

From the 'create' section, I chose the 'mirror' option, so that I can mirror the rectangle and the circle shapes as shown in the image, considering the horizontal central line as the 'mirror line'

And these are the steps for designing the middle parts,

Choosing the' x-z' plane for drawing

For drawing this part, we have 4 shapes used.

I started first by drawing the first shape which is the arc, by choosing it as a '3-points arc' from 'create' section

For the second shape, which are the circles, I chose 'center circle' option as shown, the upper very tiny circle will be used as a whole for the screw

From the 'constrains' section, I selected the 'coincident' option in order to make the circle and the arc coincident

After this, it was the time to draw the third and forth shape, the lines at the bottom of the design and the T-slot. For both I used the 'line' option.

There were many extra lines in the design especially between the circle and the 2 arcs, so I used the 'trim' option to erase the extra parts

And finally, I used the construction line that I drew outside the shape as a mirroring line to mirror the part as we will need 2 from this piece of design

On the same plane and sketch, I drew another middle part needed in the design. This part was super easy as all I had to do is to choose the 'Center to Center Slot' option in the 'create' section and then make two circles, one at each center of the slot

Also on the same plane and sketch, I drew this part which consists of two shapes, one is the circle and the other is a group of lines and finally a small circle drawn with the dimensions set in the free hand sketch, were this circle will act as a whole for a screw

The last part drawn on this sketch was simply done using the 'line' option. Where I drew the upper part and then mirrored it, also I mirrored the whole shape as I will need 2 parts from it.

Finally, these are the steps for designing the upper part,

This part consist of two shapes, the rectangle and the circle, I drew the 3 rectangles and one circle.

Then using 'circular pattern' option from create section and choosing the intersection point between the central vertical and horizontal lines as the 'center point' for the circulation, the other 4 circles were drawn

And the final step was using 'Fillet' option from 'Modify' section in order to give a curved shape to the edges of the outer rectangle as shown in the image

All the designed sketches were drawn with dimensions determined in the hand sketches

Fully defined 2D Sketches

(Fully defining a shape is done by fixing a certain point using 'fix/unfix' option in the 'constrains' section, this point act as a reference point that doesn't move once it is fixed and then from this point we start to set the dimensions to any other shape/point/line inside the whole design using the 'dimension' option )

A simulation for the design after being assembled.

Adjusting the design on 'LaserWork'

The final step was importing the design into 'LaserWork' in order to adjust the file settings and then export it with '.rdl' extension.

And the steps were as follows:

1- Importing all the design files.

2- Adjusting the parts inside the 500*300 frame.

3- Adjusting the power parameter as 65 and the speed as 20.

4-Exporting the file with a .rdl extension.

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?

For the implementation, I had to go the lab in order to use the Laser Cutting machine

After downloading the file to the machine, I started to fix the wood sheet using tapes

I chose my file and so, the machine started cutting in the wooden sheet.

Let's go home and assemble it! 🏃🏻‍♀️

Here comes the time for assembling the cutted parts !

And finally, here it is 🎉🥳

Screws and nuts that connects each of the base and one of the middle parts and also the middle and the upper part.

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 Midweek and the EOweek sessions, my group mates were active and they gave many notes and asked many questions that helped me to have a deeper understand about this week topic which is using Fusion software.

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?

In fact, as this is my first time to use Fusion 360, I was stuck in many parts during designing, but once I turned to the instructor of the group, he was very helpful and he assisted me in many situations.

One of the things that I was stuck in was putting 3 circles coincident to each other while assembling the shape. I was confused, I didn't know if I can make it using the "joint" option or not and also I was selecting the shapes not with its right order, but after the assist everything went smooth elhamdolallah.

Final Project

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

My Final Project Free Hand Sketch

Real Implemented Robodog

Learning how to use Fusion and changing an idea into a real design with suitable dimensions is such a huge empowerment and upgrading for my skills that will definitely help me in final project.

I will be able to design all of my project's parts exactly as the way I was thinking about and this is very important step towards the project I dream of.

WOW!

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

Actually, for me the whole experience was so cool!

I liked the idea of being able to think about any thing I want to implement, then starting to imagine the best shape it could be in from taking in consideration many aspects like the angle it should be designed with, the user experience (this time I played this role too xD ), the inclination of any part of the design without being broken and much more. After that, deciding the right dimensions for the design and finally the ability to simulate it easily with a lot of features that makes the simulation process as if it is real!.

The coolest thing I liked was that cube far above the right side of the page that competes a honey bunny in its sweetness, I loved playing with it while designing.
