Jointing method tests between dowels and connectors
Chair prototype v.1
Chair prototype v.0.5 (a chair & a highchair)
Plumb Modular Furniture system is a set of modular components for building diverse pieces of furniture such as shelves, tables or even chairs. Currently, this system consists of wood structures, plastic connectors and connector couplers. Basically, connectors are universal and can be shared among various structures. On the other hand, connector couplers are dedicated for specific structures. It is a unique solution to find a balance between universality and aesthetics. Users can build various furniture structures and also they can adjust or transform their structures according to the changing situations along with their life cycles. For instance, people can expand their shelves, modify a chair into a children's high chair or they even can transform a table into a shelf by changing some components in this modular system just like they build and modify LEGO structures.

The project brief was about designing a product for play. While I was trying to explore the world of play, I was fascinated by Little Shining Man (Heather & Ivan Morrison, 2011), a huge cube shape kite which consists of hundreds of tetrahedral cells. Originally, Alexander Graham Bell invented this type of kite as a form of airplane about a hundred year ago, and Heather & Ivan Morrison translated Bell's invention into a flying sculpture. I decided to explore this intriguing architectural structure. When I tried to build my early versions of prototypes according to the instructions on the internet, I realised that building tetrahedral kites with drinking straws and tissue papers is quite labour intensive especially when I made it in bigger scale with many cells. So I designed 3D printable components for easier and faster kite building and also during the design process, I found out a way to make the structure collapsible, so that it can be flatten when not in use. Consequently, this tetrahedral kite became a more accessible ‘product’, because now it is easier to carry and store thanks to its collapsible feature.

bringing books to the people in parks / 2014
1 / 5
The 1st 1:1 Prototype
1:5 Scale Prototype
The project brief was about converting an indifferent suitcase into some kind of a vehicle for mobile business or service. In my case, I designed a suitcase sized mobile library. I found that some city libraries, such as Denver Public Library and Helsinki Central Library, run bicycle libraries to broaden contact points with people. I was inspired by those ideas and tried to design a suitcase version of the mobile library to bring books to the people in local parks from local libraries. My plan was providing recent best sellers in physical format and also e-book devices that enable people to access to all the e-book archives of the library. I visited some biggest book stores to check the way they display books, and also interviewed one of the Putney library managers to check if my idea is reasonable. As a result, I designed a suitcase library that carries about 40 physical books and 20 Kindles and can be easily transformed into a book display table.
smart door lock that enables people to share properties / 2014
3 / 3
It was a 2.5 week, very short term project for the 2014-15 academic year beginning. For this project, 5 members of our group made a short film about the people's lives in 2020 as a group, and each of the group members designed a specific product that fits in the scenario of the film. Our scenario focused on the emerging trends such as Sharing Economy and Internet of Things, and I designed a smart door lock that is connected to the Internet and enables people to share their properties by the hours. It is a kind of property version of Zip Car. You can check the detailed explanation about the service, ShareSpace and the product, ShareLock with the video link on the right side.
smart food organizing system / 2014
2 / 7
Foodee Smart Food Scanner & Kitchen Scale
Foodee Scanner also can be used as an attached type scanner
Once users scan their foods, Fridge Pal app alarms before the foods go bad
The app also recommends recipes according to the inventory
And Foodee Smart Scale guides users step by step
Sketches and Renderings
The project brief was designing an electronic device that can add convenience on current online services or apps and also preparing it up to just before the start stage of Kickstarter campaign. In my case, I suggested a kind of smart food organizing system, Foodee, that consists of Fridge Pal-existing smart phone app, a food bar code scanner and a smart kitchen scale. It helps people to get the most out of foods by alarming before the expiration date, suggesting recipes according to the inventory and guiding people cooking steps with perfect portions of ingredients.
making Fairphone fairer / 2014
1 / 5
Exoskeleton modular design for the 2nd generation Fairphone
Green modular components can be seen from the bottom
Exoskeleton design makes modular structure more feasible and reliable
Most of the troublesome components are easily replaceable
Structure development with soft prototypes
Fairphone asked our programme to develop some new design ideas for their 2nd generation product. At the beginning stage of the project, I found out that their current product is not quite fairer than other competitors in terms of the physical design and repairability though they have achieved preferable system in the aspects of sourcing and distribution. Also I thought the trend of modular structure triggered by Fhonebloks is now quite popular among the mobile device developers such as Google and some Chinese manufacturer. Accordingly, I suggested the exoskeleton modular concept as a balance of flexibility and reliability.
Play-In (work in progress)
indoor activity toy / 2014
1 / 7
Rough Prototype (Seesaw Side)
Rough Prototype (Slide Side)
Veneer Laminating Test
Rough Prototype in Use (Slide Position)
Indoor Slide (age 2~4) → Bookshelf (age 5~) : Convertible Concept
Soft Prototype (Convertible Concept)
Most of existing indoor slides, see-saws and rockers are made of bulky plastic which is functionally proper but aesthetically susceptible of improvement, unfriendly for the environment and also burdensome for typical compact houses of young families. Accordingly, I decided to design an indoor multi-activity toy that is non-bulky and made of wood. As a result, I made a work in progress prototype that can be used as a slide, a rocker and also as a white board. I also have a plan to make it with a single piece of laminated veneers for the final prototype.
citrus peeler / 2013
7 / 7
Citro, quick and easy citrus peeler
Steps for peeling
Steps for peeling
Steps for peeling
Prototypes for 'test and improve' processes
Existing Peelers for peeling test
I tested existing peelers and also researched current ways of citrus peeling, and found out that the easiest way so far is using a knife and a spoon. In order to use a spoon, at first we need to make an access opening with a knife, so I started from combining those 2 functions. The first trial with 3D printed prototype was a total failure and I kept trying the make-and-test process with styrene sheet and heat gun. Finally I made a sharp tooth to make the initial opening and also hid the tooth inside the rim because I want it to be safe enough for children as well.

hacking an Argos desk fan into the mini bladeless fan / 2013
6 / 6
Redesigned desk fan using the original Argos working components
Bladeless Mini with a flag that visualizes air flow
Idea development into the function of vertical wind direction change
Rough prototype to test the wind direction control
Soft prototypes to understand the relationship between wing shape and wind strength
Disassembly of the given Argos desk fan at the beginning stage
At the beginning of this project, each of us was given one of three banal household products: a steam iron, a desk fan and a toaster. Our goal was to redesign it after we understand the products physically and contextually. My item was a desk fan. Through the disassembling process and researches about fan types, I decided to change this inexpensive desk fan into the most advanced type : a bladeless fan. Through the process, I also found some possibility of improvement of current commercial product. Instead of tilting the whole body, in this separated two wing design, rotating fins inside the body can change vertical wind direction.

Premium Washing Machine
for north American market / 2007
4 / 4
It was the first model of applying Samsung’s dual display concept. Users don’t need to see the right side display for course selection, because it has additional LCD right above the course selection knob. It also has a stainless steel deco strip right below the control panel and it makes strong character that distinguishes Samsung washers from other brand washers.
Built-in Washing Machine
for Korean market / 2007
1 / 2
System Hauzen was a Samsung's sub-brand for Korean built-in appliance market, and this washer was designed as a System Hauzen washing machine. As a high-end built-in washer, touch type control panel was applied instead of usual physical buttons and knobs to achieve temperate design language of System Hauzen line. I was in charge of the production follow-up of this project.
