Killing a joke softly with SIT (with apologies to Shirley Bassey)

     When I started writing for this blog one of my goals was to show that SIT principles are universal and can actually be found everywhere - in brilliant solutions to problems of all kinds, in stories, movies, scientific theories and in…


jokes.

Humor and creativity go hand in hand, so it stands to reason that we’ll find SIT principles in jokes (the good ones, at least).

Many people believe that analyzing jokes actually kills them, so if you’re one of those, I’m about to kill one for you…

I’d like to thank Don Young for sending in this story a few years back.

So here it is:

A wealthy man decided to go on a safari in Africa. He takes his faithful pet dog along for company. One day the dog starts chasing butterflies, and before long he discovers that he’s lost. So, wandering about he notices a leopard heading rapidly in his direction with the obvious intention of having lunch.

Creative thinking in times of war: a part of Military Basic Training?!

It’s a sad but true fact that battles and wars stretch man’s creativity to the limit.

The Nazi steel industry needed about 8 tons of water to produce one ton of steel.

Most of the water was taken from three artificial lakes that were created by massive dams. The allies knew that by demolishing these dams they could create a bottleneck in the Nazis’ war machine.

But the dams were massive structures (one was 40 meters wide at the base, 8 at the top, and 50 meters high). A 30-ton bomb would be needed to create significant damage to the dams.

Unless…

Betting on Leaves


One of your boastful friends makes a bet with you that he can tell you in no time at all exactly how many leaves there are on a tree at any given moment. Of course you agree to the bet - it seems like the quickest way to earn a free meal in your favorite Italian restaurant. As soon as you’ve made the bet, you figure out the catch: how the hell can you prove him wrong?

I’ll give you a few minutes…

License to Invent

Everywhere in the world, and especially in countries that are still not fully computerized, the law enforcement authorities are faced with huge problems regarding unpaid fines, and this is especially true for parking fines. Do you pay your parking fines? You don’t have to answer that… let’s continue with the story.

Because of this problem, the law enforcement authorities have devised an excellent way to force us to pay our dues immediately - they simply tow the car away. However, towing is a clumsy and expensive process.

I once heard a novel solution to this problem from the city of Kiev, in the Ukraine.  It appears to have been taken right out of the school of Systematic Inventive Thinking.

What do the authorities there do when they come across an illegally parked car? They simply remove the license plates from the offending vehicle and take them to the depot.

Innovative Aunt-ing

A big part of my life over the past three years has been dedicated to my role as an aunt. I can proudly say that after gaining hours and hours of “Rani (my nephew’s name) time,” I am a certified (some would say “certifiable”) aunt.

I do enjoy spending time with my nephew, but the little fella sure knows how to keep me, and mostly his parents, on our toes.

I want to share with you an incident that I am sure all of you who have kids, are related to kids or watched over kids, are familiar with. Bear with me through the description of the incident because, at the end, I would love to hear about your experiences as well.

During a game at a play date last week, Rani banged his head against a window and started crying. You know, that type of crying that makes even the iciest of hearts melt. I ran to him, breaking the 2.5-meter world record, took him in my arms, and rocked him against me while murmuring the most ridiculously ineffective things such as “shush now, don’t cry, the pain will go away soon” or futilely getting him to look at the new crayons on the table. While his sobbing continued as strongly, I was thinking to myself that I have to do better – and different – if I want this to work - which led me to the SIT inventive problem solving approach.

I reminded myself that one of the characteristics of inventive problem solving is that the problem is the solution. This led me to the realization that my salvation will not come from bizarre traditional sentences such as “the pain will go away by your wedding day” or external resources like the crayons on the table. Rather, I need to focus my attention on my crying nephew in order to come up with an inventive solution.

Do we really need inventive thinking tools?

Despite the innovative, inventive image I am accredited with (for no substantial reason), the mobile phone in my possession until two weeks ago was of one of the very first generations, and it certainly fulfilled my basic communications needs. However, during my last family trip to Ein Tamir (a water-filled spring tunnel in Nahal Kziv) I accidentally left my phone in my pocket and as I emerged from the water, soaked through, I found that the instrument had ceased to function. About an hour later, at home, I deconstructed the device and, using my daughter’s hair dryer (”utilization of existing resources”, or in SIT lingo – implementing the rule of Task Unification) I succeeded in making the phone functional again… with the exception of the display screen that could not be revived.

While my wife and daughter (clearly post-modern women as made obvious by their choice of mobile phones) began pressuring me to get rid of the device and replace it with one of a more advanced generation, I kept considering what could possibly be done with a screen-less yet functional mobile phone. The idea that flashed through my mind, spiced with a bit of black humor, was “Why not sell it to a blind person?”

But now a little more seriously… Any SIT New Product Development (NPD) workshop addressing mobile phones would inevitably, in a structured and systematic manner (by applying the Subtraction tool), reach the potential product: a mobile telephone for the blind. The end product would have no display screen (the subtracted component), but would have supporting functions appropriate specifically for a blind user.

How do you put a giraffe in a refrigerator?

Mind bogglers are problems in which solutions are simple and straightforward, but for some reason or other run counter to human intuition.

Today I present to you with two classic mind bogglers. Let’s see what we can learn from them.

The first one is a classic and I’m sure many of you actually know it:

Three travelers go into a hotel and are charged $30 for a room. They each contribute $10. That evening the hotel manager realizes that the men were overcharged. They should have got a group discount and paid $25. So he sends a bellhop up to the room to return $5. The three travelers however cannot equally split the $5, so they give the bellhop $2 as a tip and keep $3 which they split among themselves - $1 each.

Now each traveler has paid $9, for a total of $27. The bellhop has2$. So $29 is accounted for.

Where has the 30th dollar gone?

What’s a problem?

Many people would say that a problem is “a gap between a desired situation and the existing one”.

I don’t agree with this definition.

We would like life expectancy to be around 150 years (and come to think of it, why not even older?) The fact is that it currently isn’t 150 years, and yet we don’t really (at least not directly) label it as a problem.

So a better (and still not complete) definition of a problem would be, “a gap between a desired situation and an existing one that we have reason to believe we can eliminate”.

This is interesting: some people would regard a certain situation as a problem because they believe there may be a solution, while others wouldn’t see any problem because they can’t even envision a way to a solution.
