A description of how we solved a mission impossible for Tetra Pak.

1. Company Profile
 Tetra Pak is the world's leading food processing and packaging solutions company. Working
closely with their customers and suppliers, they provide safe, innovative and environmentally
sound products that each day meet the needs of hundreds of millions of people.
Innovation Challenge
 For over 20 years Tetra Pak’s R&D department had been trying to overcome a problem
caused by broken locking pins used in their packing machines. Unable to solve the challenge,
they had to ask customers to replace the pin after 1,000 hours of operation to avoid failure
during operations.
Outcome (2006) – New Locking Pin Design 100 Times Stronger
 Different flow and modal analyses revealed a formerly unknown root cause of the problem. In
turn, the max stress point on the locking pin was discovered, which lead to the design and
development of a locking pin with a lifetime over 100,000 hours of operation compared to the
initial 1,000 hours.
