27 Alternate Solutions PennEngineering recommendations for alternate hardware and cost savings opportunities. 27

28 Alternate Solutions- I PennEngineering can be able to provide all of the DELTA PT16 x 4.5 mm pan head self-tapping screws with different design solutions. PEM has license with Torx, Torx Plus, and Phillips Drive System, RemForm thread profile and has capability to do both Zinc and Nickel plating. 24 x Pan head DELTA PT16 x 4.5 mm overall length 2.4 mm head diameter 0.7 mm head thickness 00# Phillips Recess Self-tapping threads No locking patch used Nickel plating Fig.3 28

Alternate Solutions - II PennEngineering can be able to provide different sizes and installation brass inserts to meet the application requirement.

29 Alternate Solutions - II PennEngineering can be able to provide different sizes and installation brass inserts to meet the application requirement. As a alternate solution, TackSerts and Type MSIB micropem Insert shall be a good way to achieve savings in operating cost and improve efficiency in applications. 29

30 Alternate Solutions - III PennEngineering can provide different sizes of metric micro screws to meet the application requirement. PEM has license with Torx, Torx Plus, and Phillips Drive System and has capability to do both Zinc and Nickel with different color. As an alternative solution, PEM TackSert can be used to replace the traditional micro screws for achieving savings in operating cost and improve efficiency in applications. 30

31 Alternate Solutions - V M1.6 threaded Insert could be replaced by a new part depicted in the print in the right. The design in the right may be a good way to achieve savings in operating cost and improving efficiency in applications. Fig.3 32

32 Conclusions and Summary Samsung Gear VR 33

33 Conclusions and Summary Throughout the entire teardown process, we discovered 24 pieces DELTA PT16x4.5 mm pan head self-tapping screws, 10 pieces brass made M1.4 threaded insert, 7 pieces metric profile thread screws and one brass made M1.6 threaded insert in the device. All of these fasteners can be replaced by PEM, same size micro fasteners. As an alternate solution, PEM TackSert fasteners can be used to replace the traditional micro screws for achieving savings in operating cost and improving efficiency in applications. For the Alternate Solution V, borrowing experience from the Core Size TackSert design, manufacture, installation and testing the ideas illustrated on the slide #32 may be a good way to achieve savings in operating cost and improve efficiency in applications. 34
