Paving the way
The story behind
Dr. Leonhard Klein, one of the AM Program Mangers at OECHSLER, used his summer vacation for hiking. After several hours of wandering, his shirt was uncomfortably damp in the carrying area of the backpack. As usual, he changed his shirt and went on. Even with very high quality equipment, the unpleasant wearing comfort remained in the area where backpack and body met. Other hikers also seemed to have the same problem, as it turned out during the hut rest. Back in the office, he took a closer look at this supposedly unavoidable problem.
What would a perfect carrying strap have to look like in order to minimize the feeling of warmth and friction in the carrying area?
Afterwards, the hands on OECHSLER Additive Manufacturing Team got down to redesign the conventional back padding. Various analysis about pressure points were absolved to built the perfect geometries and start file programming as well as the first printing tests. A few weeks later, they were able to subject the first printed back padding including the abdominal belt to a wearing test: and felt a tremendous improvement.
