The current line of pagers uses screw inserts and screws to fasten the back cover onto the pager housing (fig. la). Each pager also has a lanyard pin for an optional lanyard accessory. Both the screw insert and lanyard pin are secondary operations. Each part is manually press fit into the plastic pager housing prior to final assembly. The two operations have two potential DPU's and add cost to the final assembly. Following is a proposal to combine these separate components, the screw insert and lanyard support pin (fig. lb). The new device combines the functionality of two separate components, a screw insert and lanyard pin by utilizing the outer cylindrical surface of a modified screw insert to also support a lanyard (fig. 2). The new device will be press fit into a pager housing using similar techniques as previously. This eliminates one assembly operation and reduces piece part count. The cost savings realized by using this design approach can be substantial. The material costs based on similar components would be reduced by $011, and labor costs based on I.E. time studies would be reduced by $.039. The total cost savings by implementing this design would be $.05 per pager. If this design had been implemented on the Bravo paging line cost savings of $215,000.00 would have been realized over the life of the product.
