Problem to solve : vertigo at the museum

During the building of a new museum, a huge amount of very old houses - ruins actually - has been excavated at the level of the foundations. As these very old houses' ruins are part of the history exhibited in the museum, they should be visible for the visitors. There is some place outside the museum with a balcony which allows to see some parts of the ruins. But at other places, namely outside and inside the museum, it is not possible to further use a balcony, because space is needed for the visitors.
Therefore it has been decided to use a usual steel structure with the shape of a large grid, which supports thick glass plates where the visitors can step on. Through the glass plates one may contemplate the ruins.

But two problems arise :

* people may be surprised by the sudden height feeling when they first step onto the glass plates, and eventually fall down

* even if people are warned, they may momentarily suffer from vertigo, or at least feel unease

For the first problem a non inventive, obvious solution was found : the people are warned by several yellow warning blocks.

For the second problem, an inventive solution was found (or used if previously found by somebody else).

It is suggested to solve the second problem.

Hint : use the already introduced TRIZ tools, i.e. determine the technical contradictions, find the underlying physical contradiction, and solve it

TETRIS : a way to learn TRIZ

If you :
* would like to have a further introduction into TRIZ, and you would not like to buy a TRIZ book
* would like to have a complete introduction to TRIZ, and you have already bought TRIZ books
* even are a TRIZ practitioner
you may be interested by the website of the TETRIS project.

In particular, the TETRIS project website provides (after due registration) the possibility to download a very complete TRIZ course. Five additional tough problems are proposed with usual mistakes and control solutions.

I forgot the following information : the access to the documents is for free. Very appreciable initiative !

Natural born inventor : Jean-Claude Novaro

I have a great respect for inventors. Above all I deeply respect independent inventors ; I call them "natural born inventors", because they always have a high intuition and cleverness, and these characteristics may be seen as natural. Actually these people are always passionate about their professional, technical activity, and work really hard. Through hard working and passion they gather such a profound knowledge and experience of their matter that they become real masters, who are then able to invent and to innovate along their career.

Arnaud, an excellent friend of mine, economist, seasoned sculptor, and passionate about arts, introduced me some years ago to such a natural born inventor, namely Jean-Claude Novaro. I was very lucky to see him glassblowing one morning.

Jean-Claude Novaro is a worldwide known glassworks artist living and working on the French Riviera. As explained on his gallery's website (http://www.galerie-novaro.fr/novaro_english.html), he was taught by a great master and further pursued his apprenticeship by self-searching and self-experimenting. This is the mark of great inventors, innovators, masters and artists : they have never finished experimenting and learning. They constantly evolve.

He told me about two great technical innovations which he introduced in the world of artistic glassworks, and which allow him to enhance his artistic power :

* a way to introduce thin gold films into his glassworks (see example below) : the problem to solve was that at the glass working and blowing temperature, gold melts and therefore cannot be introduced

* a way to make so that glassworks generate phosphorescent light in the darkness, after having been exposed to daylight (see example below)

These technical solutions are kept secret.


By the way, there are three ways to protect an invention :
* to keep the secret
* to obtain a patent
* to publish a part (sufficiently in order to impede its patenting by somebody else, and insufficiently so as to make copies very difficult)

TRIZ master Nikolai Khomenko

In the last post I shortly wrote about OTSM-TRIZ and his founder, TRIZ master Nikolai Khomenko.

A few days later, I was informed by a TRIZ colleague that Nikolai Khomenko passed away, aged 57. He was so young. Sad news for the TRIZ community... Some testimonies and comments about this very much appreciated man and TRIZ figure can be found here :
