De speelkaart: Zes eeuwen des duivels prentenboek (Dutch Edition) [Nico Peters van Berkel] on *FREE* shipping on qualifying offers. He succeeded in inspiring a whole generation of mechanical engineers and his work has been published as “des duivels prentenboek”. It has been and still is. The collection can be regarded as the first version of the design principles book, written in Dutch, and commonly known as ”Des Duivels.

Design Principles is duivel of the most renowned training courses given by the Mechatronics Academy and the High Tech Institute. The course remains firmly anchored in the foundations laid down by the renowned Professor Wim van der Hoek. The biggest changes are the addition of new top specialists and new focus points. The training course is now known as Design Principles for Precision Engineering. Yet we had no other option.
Design Principles (course) still firmly anchored in Wim van der Hoek’s ideology
Piet van Rens, who was for a long time the face of the course, wanted to considerably limit his work as a structural engineering trainer.
He has a lot of fun in the projects he does for ASML, but his agenda is prentenblek too full. Piet van Rens was for many years the face of the Design Principles training course. Duive,s continues as a course trainer but is no longer a course director. Thus, Van Eijk and Rankers had to go in prentenbowk of successors. They took advantage of this situation to reformulate the training course itself. For approximately a year now, the training programme has been in the hands of a strong team of specialists from the Dutch precision world.
In addition to Van Rens, a handful of top experts have been found, to immerse the course participants in trusted fundamental knowledge and insights, as well as in relevant additions to the engineering field.

Thereafter, the new prentenboei programme was fully booked and awarded an average score of 8. The knowledge and experience for the design principles training course Design Principles comes from lrentenboek ideology of Wim van der Hoek, the renowned Professor of precision technology, to which Dutch high tech owes a lot of its design principles and knowledge.
Van der Hoek devised a number of essential design principles in the sixties and seventies, such as the famous hole hinges, with which machine builders could achieve nanometre precision.
In addition, Van der Hoek gained great fame by collecting unsuccessful designs and and included them in Chapter 13 of his infamous Des Duivels prentenboek.
He stated that you learn best by making mistakes. The easiest and cheapest training is by getting to know those mistakes. Huub Janssen is the new figurehead of the Design Principles training course. The precision engineer honoured his mentor by naming the new meeting and demo room at Janssen Precision Engineering after the person who had inspired him, Wim van der Hoek.
The updated training course includes countless new elements. For example, there is more attention given to damping and to advanced elastic elements which have a somewhat larger stroke. Elastic elements are often limited in their range of motion, but there are concepts available which achieve larger strokes.
This is one of the research topics of Professor Dannis Brouwer from the University of Twente, who imparts a day of training on flexure mechanisms. Brouwer also handles energy compensation and gravity compensation techniques think of the kitchen cabinets that you can open and close vertically and which can stay in each position whilst they move up and down easily. That can be complicated, so we have called it energy compensation. But you can also call it energy balancing.
If previously you needed to create a positioning system, you did that with a cam drive and a drive chain up to the element that you had to position properly. In that chain you used to encounter all sorts of friction and slack – all of which is very annoying.

But in a mechatronic movement system you have sensors on your payload. They tell you exactly what the position or position error is. These kinds of trends make the subject choice for the Design Principles training shift, although it is still true that you can never get a high-quality system solution with rattling mechanics,’ emphasises Rankers. That is the world of complex machines and instruments for the chip industry, astronomy and space travel.
To position more accurately than a micrometer, you cannot simply use standard functional elements such as bearings. Then you come to elastic elements, no friction and those sort of things. After that it becomes exciting, because you are very close to physics.
They have to think a bit further, analyse all the problems that may arise.
If you can see that, the way to the solution is close. During his part-time professorship, Van der Hoek asked his students to do thought experiments. We had fes make ourselves so small that we were sitting between those spinning balls.
Then you prentenboke that the ball on one side is against the ring and on the other side has room to play. It is no coincidence that Janssen wants to enrich the training by injecting experience and exercises. Of course they are needed, but calculating is the last ten percent of the job. Primarily, designers need to get a feel for the details.
What should they pay attention to? How do they solve matters?
You first need to know where things can go wrong and then come up with a good conceptual direction. I especially want to instil intuition.
Calculation techniques will come after that. Then we have a large group discussion. In other organisations, the training is also available as a three-day variant. Piet van Rens also has experience as a prntenboek for this three-day variant. He wants to emphasise that participants in the short version really miss something.
This means that some engineering firms then choose on a costs basis or for an evening version. Practical exercises are the most valuable component of the Design Principles training course. They ensure that the contents really sink in and the participants actually understand and apply them to their work. This hands-on element is precisely what is killed in the shortened version.
This effect is noticed more when learning after a normal working day, people are tired in the evenings. If you only give lectures, then the outcome is really less effective,’ states Van Rens.
High Tech Institute organises the training ‘Design principles for precision engineering’ twice a year. Also, it is available for incompany editions.
