Our entire lives we’re busy protecting everything around us, ranging from our children’s health to the car we drive. It’s not always made easy for us to do this. So, being a product designer, I’ve come up with some possible solutions that could make our protecting lives easier.


Among all the belongings I’ve ever had, the item I’ve lost most must be the umbrella (except for love). So I decided to start protecting it. I thought the half circle of the handle could extend more to make a complete circle, which works as a handcuff like lock…


Smoke Detecting Maternity Badge

In Japan, there is a “maternity mark” used for asking for courtesy towards pregnant women in public places. It’s widely used in badges, cell-phone straps, posters, signs, etc., but unfortunately there are still some people who are ignorant about it. I’ve even seen a few men who started smoking even when there was a pregnant woman around.

This white badge actually does exist, but it’s for the people around her to know that the lady with it is pregnant. So how about using it also for herself? It detects smoke and tells you glowing blue with a sign “Don’t smoke!” and the annoyed faces. It would be good for the expectant mother so that she can quickly notice smoke and get out of there.

Crooked closure

Everybody must have once opened a snack bag in such a way that it won’t close via the bag closure anymore. Yeah, you can eat up the snack and there’s nothing to worry about. But when you want to leave some, what do you do with it?

So how about a crooked closure so that you can seal it?
