1. This Is Your Paper Shredder

Manifesto
What kind of paper shredder do you use? How many paper shredders have you seen?
Most of them look alike. No specialty, no difference and no fun, of course.
It’s time to design a novel, special, precious, funny, proud and smart shredder.
Do you think you are too great to be mediocre? Then you deserve to use it.
What you use says who you are.

How to Boast
Hang it on the wall in your office and take a close look at it. Keep majestic posture.
Flat panel screen displays latest news and economic indices. Think globally.
You may put your own pictures or messages like articles about your success in it.

You have a visitor and let them see the new gadget, but not verbally. Nobody can notice that it’s a paper shredder.
Walk close to it and put your document in the slot at the top. Behave naturally.
Don’t put more than 10 sheets. It’s your secretary’s job, not yours.
Message panel on the top greets you saying “Hello! Keep off fingers.”
It starts working and the front screen shows mosaic implying its shredding performance.
Don’t worry about jam. It is fully automatic. Enjoy the visitors’ envious glances.
Forget emptying the bin. You hired maids for the chores.
She puts a bucket aside then touches the button on the top. That’s it.
It dumps sidewise and closes when it’s done.

How is it? Isn’t it so cool?

2. Tape Dispenser

During my years in the industry, one of my inventions was a tape dispenser designed for workers in a solar panel factory. The overall process was very similar to glazing. Once a glass-covered solar panel was prepared, workers enclosed its girth with aluminum frames for the sake of protection and installation.

Double-sided tape was sandwiched manually between the panel and the frames. Taping 176 inches of the girth on the thin border, relying only on extreme concentration and care, looked very painful and inefficient.

To help them, the dispenser was equipped with many features like gradually grooved rollers and lightweight materials for easy taping.

The dispenser enabled 40x faster taping speed and higher accuracy even with one hand. It became very popular and now most solar panel makers in Korea are using the dispenser.

3. Safe Subway

A half decade ago, there was a subway catastrophe in Daegu, Korea caused by an insane incendiary. The desperate arsonist poured a gallon of kerosene in the car and threw burning matches to the floor. Just after he escaped from the chaos, electricity was cut off, sprinklers spouted out, toxic gases asphyxiated 340 people, and nothing left in the total blackness. The accident was an intense motivation for me to develop a super-high flame retardant material.

When heated, nanocomposites in the material release water and form rigid covers to extinguish fire effectively.

Now interior panels and cables made out of the materials is globally used. Feel the safety in subways and trains in US (MBTA Commuter Rail), Canada, New Zealand, Turkey and Korea.

The research was performed in Carnegie Mellon University with supports from National Science Foundation and Korea Research Foundation.

4. Way Out

Fire causes enormous loss of property and life. Since inhalation of toxic gases and suffocation leads to most victims, apparatus for efficient breathing is necessary to save people in emergency. Introducing exits and escape way is another requisite for the apparatus.

“Way Out” consists of fire alarm, beam light, exit indicator and flashlights holding masks to help people escape faster and more efficiently.
