Are you guys familiar with the art of Chindogu?
http://en.wikipedia.org/wiki/Chindogu
Chindogu is the not-so-ancient Japanese art of inventing ingenious everyday gadgets that, on the face of it, seem like an ideal solution to a particular problem. However, Chindogu has a distinctive feature: anyone actually attempting to use one of these inventions, would find that it causes so many new problems, or such significant social embarrassment, that effectively it has no utility whatsoever. Thus, Chindogu are sometimes described as 'unuseless' - that is, they cannot be regarded as 'useless' in an absolute sense, since they do actually solve a problem; however, in practical terms, they cannot positively be called 'useful'.
Literally translated, 'Chindogu' means weird / unusual ('chin') tool ('dogu'). The term was coined by Kenji Kawakami, a Japanese inventor and writer who first made the idea prominent in a book translated into English, in the mid-nineties, as 101 Unuseless Japanese Inventions: The Art of Chindogu. The popular success of this book prompted a follow-up, 99 More Unuseless Japanese Inventions, which was published a few years later. Together, the books have sold nearly a quarter of a million copies in Japan alone, and have been translated into most of the major world languages. Examples from the books include:
- a combined household duster and cocktail-shaker, for the housewife who wants to reward herself as she's going along;
- the all-day tissue dispenser, which is basically a toilet roll fixed on top of a hat, for hay fever sufferers;
- duster slippers for cats, so they can help out with the housework;
- the all-over plastic bathing costume, to enable people who suffer from hydrophobia to bathe without coming into contact with water.
There are ten key tenets to bear in mind, if you wish to design a Chindogu. The principal among these are: (a) it has to be possible to make (ie, it has to actually exist), in spite of its absurdity; (b) it has to remain in the public domain (ie, it cannot be given a patent); and (c) it must not be exclusively a vehicle for humour, or the warped satirical worldview of the inventor. There is frequently humour in a Chindogu, of course, but this should properly be regarded as incidental, rather than as an end in itself.
