Coffee Capsules Holder – 5 Constraints

For my coffee capsules holder design, I have some constraints that I need to take into consideration to achieve the idea in my head. The constraints are as follow:

1- Aesthetic

For this project, I decided to have a modern and luxurious aesthetic. To achieve that, I am planning on buying some fine material that will add the luxurious part to the project. In addition, I will be adding some unique engravings and/or pattern to support my view.

2- Symmetry

This is one of my important constraints as it represents my personality. I have always noticed that symmetric objects and drawings usually draw my attention just because the way they look. For my project, it is going to have four sides similar to a box and what I am planning to do is have the sides facing each other identical. This way it will be symmetric in two directions.

3- Mechanical function

Part of the project requirements is to have a moving part. It does not need to be mechanical, but this is what I chose for my project. I am planning on using ball bearings to allow the ‘box’ to rotate freely. In addition, I might be using some magnets to allow the box to stop smoothly and at certain points.

4- Precision

Precision is usually necessary for most engineering projects, but I believe it is crucial in my project because I will need to glue several parts together since I will be using acrylic. However, this should not be an issue as I will be using the laser cutter with is very precise. I just need to pay extra attention when assembling everything together.

5- Size

I will be graduating this semester, I hope, and I am planning on taking my project back with me home. Therefore, it needs to be a relatively compatible size to take on an airplane or ship safely.  Ideally, the project should be easy to hold and handle by an average person without using excessive force.

    Hey Abdul, I love your aesthetic for this project! I think it matches the purpose of your coffee capsule holder in a good way. Do you have any ideas for what material you will use? I also love how you are making it movable, I think it adds an advanced dynamic to the project. I can’t wait to see how it turns out!

      Thank you Hailee! I am planning on using black and red acrylic to match my coffee machine. Hope it turns out well!

    I like the idea for this project a lot. I was wondering exactly what kind of material you’re going to use to make it , as you don’t specify. I am also curious as to the exact specifications of your moving part, and how the box will open. Looking forward to seeing your project!

      Thank you Rhys! I am planning on using black and red acrylic to match my coffee machine. To make it rotate, I will probably be using something called ‘lazy susan’ to allow it to rotate. To make the rotation movement more appealing, I will be adding magnets in the 4 corners to prevent it from moving very easily. As to how it opens, it will have a lid at the top with a simple circular hole in the middle to take it off.

    Hey Abdul,

    I really like your idea for using magnets in the mechanical aspect of this project, I think I’ll try to use it in my own as well! I think it will make the box a lot funner to spin as well, especially if you have the magnets placed closely enough for it to “snap” to a position. There are lots of strong magnet options for pretty cheap on amazon. One question, are you planning for the top of the box to be open, or closed to make a cube?

      Thank you Thomas! The magnets indeed will make it look more elegant and stable. The top of the box will have a simple lid with a hole in the middle to lift with a finger. If I ever decided to not use it, it can simply be removed.
