Initial specifications were determined by technology partners. Kodak used these specifications as a guideline for creating our Advantix camera, however, Kodak's design, based on our manufacturing capabilities used smaller draft angles than the specifications.

Software was used to evaluate the ability of the cartridge (per specifications) to "find" the film driver and door driver as the cartridge was inserted into the chamber. Several different bias conditions (where the cartridge is in contact with a chamber wall) were evaluated.

Then, alternative chamber designs (larger, Smaller and specified draft angles) were evaluated. The looser - than - Kodak specified draft angle simulation indicated that an unacceptable number of cartridge insertion would not result in the proper seating of the film and door drivers.
