Concept Generation for Creasing Differentiation
(2013) MMK920 20131Innovation
- Abstract
- This report is a result of a Master Thesis project in mechanical engineering by Stefan Larsson. The thesis was carried out at Tetra Pak, Packaging Solutions AB at the department for Mechanical Engineering and the Division of Machine Design at the Department of Design Science at LTH. The thesis was produced during January to June in 2013.
Tetra Pak has always been in the forefront of development, continually trying to find new solutions and packages to get ahead of their competitors. This Thesis is a way to prepare for eventual future developments. It was deemed that with the ever increasing amount of different packages, the creasing operation would at some point have to be developed into a more flexible system. Ordering a master’s...

Tetra Pak has always been in the forefront of development, continually trying to find new solutions and packages to get ahead of their competitors. This Thesis is a way to prepare for eventual future developments. It was deemed that with the ever increasing amount of different packages, the creasing operation would at some point have to be developed into a more flexible system. Ordering a master’s thesis to investigate possible solutions and concepts will save a lot of time when the order for development finally comes.
The aim of this thesis has been to develop a wide selection of ideas and concepts as a pre- study to the possibilities for a future increase in flexibility. The flexibility that is desired is to be able to change the creasing pattern on the rollers instead of always changing the whole base module that is very expensive. If that is possible in an efficient and simple way then the gain could be very large.
The main problem has been how to achieve the extreme accuracy that today can only be achieved by a mounting done by experts during one to three days. The same accuracy is now demanded from a mounting done by factory personnel in less than 2 hours. With that timeframe and the problems that will arise with room for fastening as the flexibility increases, will make fastening of the creasing pattern the second most important problem.
The solutions that I have developed are in a wide range from cheap and small to expensive with great potential. The remaining ideas and concepts in this report are the best of each category. That kind of selection has removed many good ideas for better ones in the same category while some rather uninteresting ones remaining. This kind of selection is motivated by the fact that selecting the future solutions depends on many different factors that are hard to predict at present time. Therefore I have made sure that whatever the decisions and ambitions in the future they will find ideas to use in this report. (Less)
