Jimmy Jeong: Create and Improve

Create prototypes based on the chosen design.

After creating a representative model of the rollable table using simple materials during the Develop and Plan stage, I moved onto the second prototype.

My second prototype involved a little more complex materials and methods to build the rollable table. Instead of physically cutting out cardboards (which can have rough edges and imprecise measurements), I used the laser cutter to make the design of the table more clear and neat.

Below are some major changes between the Develop and Plan stage Rollable Table and Create and Improve stage Rollable Table.

Types of Changes Develop and Plan Rollable Table Create and Improve Rollable Table (prototype)
1. Measurements -Involved irregular measurements in some parts of the table

-Consisted of different types of cardboards (can disturb the shape of the table)

-Used the laser cutter with accurate measurements (adobe illustrator requires correct measurements)

-Same materials were used (same cardboard in cutting)


2. Rollable Part/Section -Used straws, papers, and glue guns (does not have enough flexibility to roll)

(See bottom of this table for pic**)

-Folded cardboard, hard paper, and small robotics wheels were used (builds smoother rolls)

(See bottom of this table for pic**)

3. Bottom Surface -Used a simple cardboard for the bottom section (table does not stand well once the rollable section is attached) -Used a stronger connecting method (the cardboards were connected through fit and slide method)

See bottom of this table for pic**:

Since the rollable part/section is the most important aspect for this product, the pictures below show a more in depth explanation.

In the Develop and Plan Rollable Table, I just used paper and straws which did not necessarily work all the time. It was hard to roll due to its lack of flexibility.

However, in the Create and Improve Rollable Table (prototype), I went through different websites to find inspirations that can help me find a way to roll more easily. Consequently, I was inspired by the tanks’ mechanics of wheels. Tanks’ wheels are in the format of rolling the wheels and adding a layer of material around it.

I liked this idea of how it rolls, which made me to visualize how I would make a rolling section just like that. I found piles of robotics wheels in the design lab and I decided to make use them. I connected two wheels at a time with a strong piece of thin wire. I made 10 pieces of those.

Next, I found two materials that can cover around the wheels. I decided to use a folded cardboard and a hard paper. I tested out both materials to go around the wheels and felt how rollable the two materials were.


Below are two videos of how rollable each of them were.

IMG_3941 (video of hard paper material)

As we can see in the video, I thought that both materials were not effective for making the wheels roll. To reflect, I need a better material that perfectly goes along with the robotics wheels so that it functions easily to roll.

My Create and Improve Rollable Table (prototype) looks like this as a whole:


Test your design with your chosen audience. Use data to guide future changes.

I received feedbacks/advices from peers in our assigned group and teachers in the fab lab. There were two main things pointed out for improvement.

  1. I needed to figure out another way to make the rollable section/part to function well. The rollable section was not rolling and needed some physical adjustments in order to have it actually roll.
  2. I needed a stronger base of the table to let it stand itself. The bottom part of the table that stabilized the whole structure was weak, so often times it was unable to stand.

I decided to test out with different materials and brainstormed some ideas to let the rollable section roll. One of the fab lab teachers recommended me to put in distances between each robotics wheel (a little different from the tank wheels).

Based on the feedback, I made some changes to my design. I found techniques to make things roll. Out of 5 methods, I chose the middle wheel method. Below is a picture of what the method looks like.

I found different shapes of robotics wheels in the design lab and applied it to the method.

I inserted two small wheels in the middle between the two big wheels, because when the cardboard that is covering the outside rolls one time, the small wheel has a space where it will eventually fall out. This new way rolled much better than the previous two, however, each time I rolled it, the cardboard’s length kept on increasing. The cardboard was constantly stretching which eventually made a bigger area inside. This was a problem that I noted so that I can improve on my final design.

I chose the last method to further expand and use it later on.


Create a high quality original product that is visually appealing and functions well.

For my final design, I used the laser cutter to cut my table section. The edges looked more smoother and I thought that the table looked more neat. For all my designs, I used a fitting method for every piece. The perimeters of the pieces were all shaped like a lego piece so that it will attach better with other pieces. Below is a picture.

For my rollable section, I expanded on my final design. I got some recommendations on having the rollable section be more fit into the bottom of the table section. I used small needles that were usually used inside a sewing machine. The needles helped me to balance my rollable section without falling down.

Below is a picture of my final product of the ‘Rollable Table’.

Below is a presentation poster that shows the whole features and details of the final product!

To reflect, I think that at the very start of the project, I should have found out more inspirations and techniques as to how the rollable section would work. It took me too much time to just work on the rollable section, rather than finalizing my product with the highest quality. If I worked on this type of project another time, I would carefully think about the specific processes and methods I should use to create the best design.

Jimmy Jeong: Develop and Plan

Use different techniques to generate as many ideas as possible.

On the notebook, I brainstormed several ideas on different criteria. I focused on three main criteria which were ‘Rolling’ method, color/designs, and materials. Each sub-topics were linked with specific criteria to gain various ideas. I used this brainstorm format from the inspiration from ‘poplet’. This brainstorm allows me to look back at a wide range of ideas if one of them did not work out well.

I tried to brainstorm ways I can make specific parts of the table. The parts included the ‘Rolling’ section, shape of shelves, color of shelves, and all other related parts of the table. Below are some quick sketches and ideas that I tried to brainstorm.

‘Rolling’ Section Brainstorm

Color of ‘Rolling’ Section Brainstorm



Model and share your ideas. Justify your choices.

I drew some observational drawings for different tables that had shelves attached to them, because they had the most similar aspects on what I was trying to design.

For my first observational drawing, I added my ‘rolling’ section as an attempt to visualize what I was going to make. The color or the shape of the table was what I was aiming to look the same.


For my second observational drawing, I just tried to draw the exact same shape of another table.


Make a detailed plan including time and resources.

In this stage, I decided to use cardboards, straws, and simple materials, because it was a rough model of what my final product was going to look like. I made a small-scaled size model of the Rollable Table. By recording measurements, quantities, and other necessary details, I made a detailed plan that includes a list and a sketch.

Detailed Plan


  • Cardboards (laser cut?)
  • Ruler
  • Pen
  • 10 Straws
  • Tape/Glue gun
  • 2 A4 Paper (Black and White)


  • 20~25cm by 8~10cm Floor/Top Cardboard x4
  • 15 cm by 8~10cm Sides (1) Cardboard x2
  • 3cm by 3cm Cut Rectangles Cardboard x4
  • 8cm by 8~10cm Sides (2) Cardboard x 2
  • 6~8cm Cut Straws x?
  • Paper 6~8cm by ? x

-General Order:

  • First, I would cut out all the cardboard pieces I need with precise measurements.
  • Second, I would cut out the straws and paper pieces I need with precise measurements.
  • Third, I would put together the general shape of the table using cardboards (excluding the rolling section for now).
  • Fourth, I would stick the pieces of cardboards with the glue gun.
  • Fifth, I would make the rolling section using straws and papers in a different place.
  • Sixth, I would attach the rolling section onto the general shape of the table with cardboards.
  • Lastly, I would fix any fragile or unnecessary parts.


I drew a sketch of separate parts of the design. Since the materials used in this model are mainly cardboards, I first sketched different parts and added measurements along the way.


How will you know your design is successful? What is the success criteria?

Below is the success criteria table. Based on the success criteria, I can judge whether my product was a success or not later on.

Success Criteria Explanation
The Rollable Table needs to be easy and convenient for the customers to use. Whenever a customer rolls the handle, the rollable section attached to the table should roll every time.
The Rollable Table needs to be easily moveable. Since a table is a furniture that may be placed in several locations, it should be always ready to move easily. For my Rollable Table, this would be a challenge to consider, because the rollable section would need to be strongly attached so that it would not fall off.
The Rollable Table should have a non-rolling section. On the table, people may want to place objects that should not roll off the table. A stabilized section, just like a normal table, is needed in the Rollable Table.


Through the whole process of planning out my idea for the first prototype, I created my first Rollable Table using simple materials. I included specific measurements and developed some ideas for the rolling section along the way.

In the future, when I create my final product, I am going to use a laser cutter to build my table part and advance my rolling section using more strong materials.

Jimmy Jeong: Define and Inquire

In this project, our objective is to create a product that can resolve a certain design problem. Out of the four stages of the design process, this post is about the ‘Define and Inquire’ stage.

I started off by finding numerous inspirations from various resources such as Pinterest, Designspiration, etc. Consequently, I decided to focus on three main topics of design which were: Small Scale Architecture, Useful Furniture, and Juice Box Packaging. I particularly preferred the ‘Rollable Table’ under the topic of Useful Furniture.

What are the specific details of the problem? What are the constraints?

3 Design Brief

(The hyperlink above is the 3 complete design brief wrote in pages)

The 3 design brief includes the Small Scale Architecture, Rollable Table, and Juice Box Packaging. I chose the Rollable Table as my final decision to build. Below is a table answering the question for the Rollable Table.

Rollable Table Design Problem: Unnecessary pieces of trash on the table can be easily cleaned with a convenient roll from the handle.

Specific Details Constraints
1.A table is split in half (one half would be a normal table and the other half would be a rollable section)

2.The rollable section of the table would have a handle attached to the side

3.Users would roll the handle and the rollable section would rotate in one direction

4.Unnecessary trash on the table can be rolled off to the floor (a trashcan can be below)

-The handle attached to the side can be disturbing possible pathways

-Every table would need to have a different sized rolling section (depending on how big the table is)

-Shifting the furniture can be challenging

-Some materials used to build the table can be environmentally harmful (ex: cover of the rolling section)


Who will the solution be designed for? What can you learn about them?

The Rollable Table is designed for people who favor using a table and wants convenience in cleaning at the same time. I mainly targeted this solution for students (uses tables the most) and businessmen.

What else do you need to know?

For the Rollable Table, I am first going to create a small miniature of the table with cardboards, straws, papers, and simple materials. I am going to plan a few prototypes and try to reflect on what I can do to improve. Then, in the final design, I am planning on using the laser cutter for the cardboard section for a cleaner and sharp form of the table.

Traditional Vine Chair

Organic Chair

(Above is the download for the mini folio-better explains the process)

Throughout 3 weeks of designing,  the design problem was to create an organic chair that was inspired by nature. Following the design process: define/inquire, develop/plan, create/improve, and reflect/share, I started off by finding some inspirations.              

The general idea was to attach various types of vines onto the chair with the addition of color (using fruits). The picture on the right was the idea I was aiming for. However, the chair looked too simple and a bit boring. I thought that people would have already seen this design at some point in their life. Consequently, not just using the theme of nature, I also added a layer of tradition to design the chair even more unique.

For the theme of tradition, I took a picture of a traditional chair at home. Unlike the previous picture of a normal chair, I preferred this traditional chair, because it was more visibly appealing and seemed interesting. Overall, I switched my idea: on the basic structure of the traditional chair I would at vines that contained colors, shapes, and other imageries.


Above are some observational drawings I tried to get more inspiration and ideas to make the chair even better.

After setting my general idea, I started to specifically plan how the actual model would look like. I had numerous materials to use and I picked pieces of cardboard and air-clay to create my design. I sketched out some models of the final model for reference when I am actually making the model.

As you can see in the picture above, I originally had some additional ideas such as adding a mask, splitting the chair in half, and other thoughts. However, I excluded some of those ideas to primarily focus on the theme of nature (the design process allowed me to have the chance to choose ideas I preferred).

Next, I began to actually create the final model. I think that this point (create and improve stage), was the most important and vital part of my whole design process. While cutting out the pieces of cardboard, I thought of a method to fit cardboards using precise measurements. Below is a visual.


In the picture, the cardboards are linked together like blocks. This ‘fitting method’ allowed my whole structure of the chair to be stabilized. Without having to use hot glue for sticking all the parts, I found this idea more efficient and effective. In order to make this method possible, I needed accurate measurements to fit the blocks in perfectly. The picture on the right shows some measurements I took along the process of creating my final model. I additionally added a second row on the sides of the chair to try to design it like the traditional chair at home.


For the inspiration of nature, I modeled vines using the basis of a cardboard and adding a layer of air-clay on top. The shape of the cardboard was some parts leftover from a laser-cutter design. I found the shape very interesting and it matched up as a vine. I wanted to add some colors (fruits), so I used different colored (purple) air-clay for grapes. Below is an explanation.

Adding all of these methods and visuals, I ended up with my final design named “Traditional Vine Chair”.


To reflect, I thought that my inspiration of nature and another layer of tradition made the organic chair look more visibly appealing. The use of air-clay on top of a cardboard and the ‘fitting method’ were some things I thought that I did a good job on. However, next time, I would like to expand myself into using more diverse materials and going beyond the idea of just ‘vine’. I think that my define and inquire stage should have been more effective.

Designer Persona

Throughout 3 blocks in the Product Design, I created a designer persona. This designer persona contains information about myself that include personal interests, personality, goals, and other useful categories that may let others know more about me. As a ‘design’ class, the designer persona involved primarily on designing aspects. The purpose for this designer persona is to express my designing characteristics and goals for the future as well.

First Prototype (before feedback session)

During the feedback session, I received feedbacks that mentioned:

-Interests was a little hard to understand

-Explanation looked too detailed

-Use of colors was allowing clear organization

After the feedback session, I noticed that most feedbacks were critical on the ‘interest box’. I decided to change the format to bullet points instead of a paragraph. Furthermore, there was a feedback that recommended me to add a quote. I agreed to that idea and added a quote at the bottom. I conserved the positive feedbacks as it was.
