Dennis Choi Product Design by Seokjin CHOI

Straight Line Drawing

choi1250231 — 2022-09-05 05:31:15 UTC

When I first drew lines, the lines were like pasta noodles. Now, my lines are more straighter than before

Perspective Drawing Practice

choi1250231 — 2022-09-05 05:36:29 UTC

Today I did some perspective drawing. I achieved drawing 3D looking boxes. connecting the lines right to the dot was a bit hard because the lines were not sometimes heading to the right direction

Isometric Drawing Practice

choi1250231 — 2022-09-10 10:24:18 UTC

I only knew how to draw lines at first. Now, by using lines I can draw crates and also use these crates to make various isometric drawings.

Peanut Couch ( Or something like that )

choi1250231 — 2022-09-14 09:31:40 UTC

1. Explain your product, include the terms function and form in your answer.
The product is a couch. The form of it is a shape of a peanut. One of its biggest function is that it has a head rest to feel more comfortable. Also, we didn't use legs to prevent from scraping the floor.

2. Explain the dynamics of your team. Did every member have a role? Was there a natural leader?
There wasn't actually a fixed role in making the couch. However, we all had something to do. Some told what to do and some people drew schematics and made the miniature of the product. There were two natural leaders which caused a bit of chaos because the two people's ideas were different from one another

3. How did your team plan for your outcome?
We first talked about what we should make. After that we drew a simple sketch of the product. After a few discussions about what to add, we started making the physical model.

4. What techniques of modelling did your team use?
We used graphical models to draw how the product will look like. After that we used physical models to make a miniature of the product.

5. What challenges did your team face?
Like I said before, two of our teammates had different ideas about what to make. Each of the sides weren't able to understand each other's idea. That led to an argument

6. To iterate the design process, evaluate your final outcome, what would you adapt if repeated?
I think we should make the graphical model more specific to make the production of the physical model go smoothly

Isometric Drawing Complicated

choi1250231 — 2022-09-21 08:44:13 UTC

I thought that using crates to draw felt more easier and realistic. My time drawing crates reduced.

Door locking remote control

choi1250231 — 2022-09-26 05:36:40 UTC

This is a remote control that is used when we open our house door. It scans our fingerprint. If the fingerprint matches to the one registered the door opens.

There are things that needs to be changed in this controller's design. The first problem is that the product is only designed for left hands. Some people that are used to using their right hand might have a hard time holding it properly. The second problem is that the fingerprint scanner on the side might be a bit too far for people that have small hands.

To solve this problem, I could make the control smaller and move the large scanner to the side. Also, I could change the shape to make it comfortable for both hands

Rendering+Thick+Thin lines

choi1250231 — 2022-09-29 05:28:48 UTC

Drawing thick lines was a bit hard because I didn't quite know where the thick lines should be and where the thin lines should be. However, I managed.

The Rendering part was way more complicated than Thin, Thick lines. I had to re-render many times to make it look good.

2D drawings of controller

choi1250231 — 2022-09-29 05:32:46 UTC

This 2d drawing is a bit different from the isometric one. There had to be minor changes from the 2D version. However, the location of buttons and side view haven't really drastically changes

ISOMETRIC drawing of controller

choi1250231 — 2022-09-29 05:34:48 UTC

This isometric drawing took ages to draw because it had a lot of curves and the design had to be improvised a lot.
I learned that using curves as an element of a design is very complicated to draw

Remote Control Foam

choi1250231 — 2022-09-29 05:36:08 UTC

This is the second foam model that I improvised from the original one. Unlike the first foam model, this model could be used by both hands. Also, for people who have small hands, the buttons were moved from the right side of the model to the front side of the model.

I think this version of the model is better than the 1st in terms of design, comfortability.

I learned that making a many versions of the model improves the overall quality of the product

Remote Control CAD

choi1250231 — 2022-11-02 08:48:43 UTC

This fusion 360 technology was a lot complicated. At first the software was too hard to understand that sometimes it took half an hour to draw one simple line. However, compared to my first encounter with Fusion 360, I got better and some parts are getting easier.

Remote Control Rendered

choi1250231 — 2022-11-10 03:26:10 UTC

The most fun part of this fusion 360 was when adding colors to my designed product. I think the designing and rendering became easier as time passed and I had more and more experience. However, it still felt hard to make a CAD.

SandProM

choi1250231 — 2022-12-12 04:43:15 UTC

This is a sand mask that protects your entire face from sand and light. It has a light right next to your head. It has a blue transparent board that protects you from the sunlight. The board can flip up and flip down by using gravity. The thing currently uses fiber and plastic. The fiber will change into something that reflects light and blocks the sand. The plastic will change into a more flexible material. The mask is very light so it doesn't really bother your movement. I used staples to join the parts. Next time I will tie them together.

Wooden product

choi1250231 — 2023-01-15 07:27:16 UTC

This is the wooden product that I have in my house

The product's conductivity of heat and electricity is low because it is made out of wood. It is safe to touch the product in hot places unless the product is on fire.

The mass and weight of the product is quite heavy. I think the product is made of wood with high density.

The product has a very high stiffness. It can't bend unless I use mechanical forces.

The smell of the product is like the smell of a newly cut wood. It kind of smells like the forest.

Anywheel bicycle product design brief

choi1250231 — 2023-02-06 05:18:15 UTC

I designed a box that contains a water repellent fibre. I designed this to prevent rust on the bicycle. If there is rust on a bicycle, people may get injured because the chain can cause a small or big cut on your leg. If the chain is rusty, people might get a bacterial infection that could cause Tetanus. There are many causes of rust, one of them is because of rain touching the steel parts of the bicycle. Another problem might be if the bicycle is rusty, the parts of the bicycle might not work well and therefore cause accidents like faulty brake crashes. To prevent rain from touching the bicycle, I designed a box that will contain water repellent fibre. This water repellent fibre will cover the entire bicycle from rain. The box looks like a normal box because it is designed to carry other things such as candy or phone when it is not raining. The product will be two separate pieces, the box itself and a board inside the box that will be connected with the fibre. It will be separable and will be located on the top tube of the bicycle.

The size of the box will be 180cm^2 and the height will be 10 cm. The size of the hole will be 105cm^2.

Metal product drawing, annotation

choi1250231 — 2023-02-13 04:10:58 UTC

Using metal as the material of my design product would be adequate because my product is going to be attached to a bicycle and it needs to withstand a lot of wear and tear, blows and shocks caused by crashes. However, I think it needs to be an alloy rather than a pure metal because alloys are stronger and doesn't rust. Sharing bicycles are most definitely going to be parked outdoors. Rusting can easily happen because the product is exposed to a lot of oxygen and rain.

Update on Anywheel product

choi1250231 — 2023-02-23 01:51:46 UTC

I am currently in the final stages of the anywheel product. The photo is the render of the design. I used galvanized steel as the material for the product because galvanized steel has zinc coating and zinc coating prevents rust. Since this product is going to be located outdoors, the product itself needs to be rust-proof. I divided the product into 4 pieces to make it easier to print. I will use adhesives to connect the products because the printed product will be too small for joints.

Plastic

choi1250231 — 2023-02-26 06:49:58 UTC

The type of plastic that would be suitable for my product is probably Melamine Formaldehyde. MF is a thermosetting plastic. So, we don't need to worry about the plastic melting. Also MF is hard and chemical resistant. So, it is quite suitable for outdoors because plastic won't react with chemicals in the air. It is easily colored so it can have various colors choices.

choi1250231 — 2023-03-08 09:05:15 UTC

Non-woven fabric is absorbent, liquid repellent and has weak durability. It is used for Garment linings, Carpets.

Woven fabric is Elastic, tensile, and tough. It is used for shirts, jackets, blouses.

Knitted Fabric is tensile and durable. It is used for sports wears, sweat shirts.

Bioplastic making

choi1250231 — 2023-05-08 05:55:05 UTC

We tried to make bioplastic today. The plastic was made of Glycerine Gelatine, Sugar and Spirulina. The plastic smelled like green tea and it took so long for the plastic to be made. However, it was a fun experience because it kind of felt like cooking food however, the end result was kind of disappointing because there wasn't much plastic made.

Bioplastic

choi1250231 — 2023-05-11 03:21:19 UTC

This is the finished version of the bioplastic. The plastic is kind of disappointing because I expected the plastic to be hard not elastic. However, it does kind of feel like vinyl. The recipe was Mix 4g sugar with 10ml water, after that mix 10ml of Spirulina with 20ml of Water. Mix the two solutions. After that mix Gelatine and Glycerine to make Glycerine Gelatine. Mix all of the things with heat.

This bioplastic could be used for a jacket. It could also be used for Vinyl. However, I am skeptical if this can actually be used.

Case Study

choi1250231 — 2023-05-15 01:10:19 UTC

What is the difference between a circular economy and cradle to cradle concept?

Circular economy is boosting the effectiveness and making the life of the product longer while cradle to cradle is trying to make the product return to the Earth without any damage to the environment.

What are the main issues of petroleum based plastics on society today?

The product will eventually be thrown away and will remain in the environment for a long long time. Damages the environment.

What are the benefits of bio-plastics?

They do not need petroleum. Can be comparatively easily biodegradable

What are some issues that the bioplastics industry face and why?

It is not really biodegradable. Has to be burned in a compost to be biodegradable. Cannot degrade in normal temperature.

How can consumers make sure their products are really cradle to cradle?

Check what the product is made of. Try using products that have biodegradable stickers on it.

Can you find an example of a true cradle to cradle product and justify it?

A paper straw can be considered as a cradle to cradle product because it is made of paper. Paper can be biodegradable and can return to nature with less damage.

Team Design Challenge (Table)

choi1250231 — 2023-08-30 03:04:48 UTC

This is the foam model of the table that my partner Leo wants. The table's legs can move to adjust the height of the table top. To prevent the legs from slipping, I made the bottom part of the table with trenches that prevent it from slipping further. The table top also has trenches to prevent the legs from moving outside. One of the characteristics about the table is that it uses not that many adhesives. While I am satisfied with the design of the table. If this model is to be made in real size, the product will be made of wood. To be more specific, Softwood. The wood will not be manufactured due to manufactured boards being vulnerable to water. The wood, though will be treated to extend the product's life. While I am quite satisfied about the design, it is not without its flaws. One of the flaws is that it takes up a lot of space and the chairs need to be placed from a distance from the table top due to the existence of the bottom base.

Wingtip of airbus planes

Wingtip of gliding bird

choi1250231 — 2023-08-31 01:22:55 UTC

The turned up wingtip of airbus commercial aircraft is inspired by the wing shape of gliding birds

Nose of Jets

Beak of bird

choi1250231 — 2023-08-31 01:27:38 UTC

The nose of the planes is inspired by the sharp beak of the birds

Wind Turbine Wings

choi1250231 — 2023-08-31 01:32:58 UTC

choi1250231 — 2023-08-31 01:33:37 UTC

The wings of the wind turbine is inspired by the whale wings

Drawing of a pandan

choi1250231 — 2023-09-07 00:54:41 UTC

I drew a pandan. Pandan has a very sharp leaf. The leaf is very smooth but it also has very good grip due to the . If you look closer you could probably see torns that are located on the side.

Inspiration Board

choi1250231 — 2023-09-13 02:19:14 UTC

Research Board

choi1250231 — 2023-09-18 10:57:20 UTC

ATLs

choi1250231 — 2023-09-21 02:06:07 UTC

For ATLs I would like to work more on SM1 and COM 5. This is because I sometimes feel like I kind of lack optimism when approaching problems. Also, I think I kind of lack Expressing my ideas verbally because I feel like I dont talk as much.

Research Board 2

Euro Pallet

choi1250231 — 2023-11-02 04:33:53 UTC

This is the plan view for a euro pallet. As you can see, the euro pallet is an assembly of many parts. They are put together using nails.

Conceptual Understanding for Human Centred Design

choi1250231 — 2023-11-16 01:49:35 UTC

Human-centred design is a creative and iterative design that focuses on speidicifal people's needs. It helps people embrace the idea or product because it fulfills their needs.

What form of research is needed to better understand the USER, TASK, and ENVIRONMENT?

choi1250231 — 2023-11-20 06:16:22 UTC

While all the forms of research can be helpful to understand the user. I think having an interview and also immersion would be the best way. This is because from the immersion I can to some extent know what the user's environment is and what they do. Also, I could to some extent know the difficulties experienced. Having an interview on top of immersion would be helpful since I can't really experience the user 100% just by doing immersion for a few days. Also, there might be difficulties that I hadn't seen as a difficulty. There might also be long term difficulties and experience that only people that are familiar with the job may have. Therefore, I will be using interview and immersion.

Trophy

choi1250231 — 2025-05-12 11:05:57 UTC

I was thinking of creating a trophy using bioplastic. This is the design of the trophy I was considering. This might not be feasible as the structure of the trophy is incredibly sophisticated and I think the trophy will collapse due to the thin supports of the trophy.
