June 12, 2008 at 13:53The task that students are offered on TRIZ (theory of solving inventive problems)
As the decision is made, I will add more tasks.
At one of the creameries, sunflower oil began to disappear during transportation.
Suspicion fell on one of the drivers - about 10 liters of oil were missing on each of his flights.
The tank for transporting oil looks like a tank with kvass, only the big one - at the top on one side is a large and wide hatch where oil is poured, at the bottom on the opposite side is a tap through which oil is drained.
The driver’s route is the following - in the morning he arrives at the car depot, where he is given an empty tank - then he goes to the creamery, where sunflower oil is poured into the tank - then he goes to the creamery, where the oil is drained and processed - then he returns the empty tank to the car park.
At first they thought that the matter was in the tank - they began to change the tanks - the oil still disappears.
Then they thought that the driver was draining oil on the road through a tap or scooping out of the hatch, they began to fill the hatch and the crane in the creamery after filling in the oil - the seals were intact at the creamery, and there was not enough oil.
Finally, they drove the forwarder to the driver and he accompanied the driver from the creamery to the creamery - there is still a shortage of oil ... The
question is - how did the driver pour oil?
