                                                Review two potential battery options:









                                                •  A single 6-volt lantern battery.









                                                •           Four 1.5-volt D cell batteries.








                                                The two options affect the product design and specification. Think about it.









                                                A single 6-volt lantern battery is approximately 25% higher in cost and 35% more in



                                                weight. The 6-volt lantern battery does provide higher current capabilities and longer




                                                battery life.









                                                A special battery holder is required to incorporate the four 1.5 volt D cell configuration.



                                                This would directly add to the cost and design time of the FLASHLIGHT assembly.









                                                Time is critical. For the prototype, you decide to use a standard 6-volt lantern battery.



                                                This eliminates the requirement to design and procure a special battery holder. However,




                                                you envision the four D cell battery model for the next product revision.









                                                Design the FLASHLIGHT assembly to accommodate both battery design options.



                                                Battery dimensional information is required for the design. Where do you go? Potential




                                                sources are product catalogs, company web sites, professional standards organizations,



                                                design handbooks and colleagues.









                                                The team decides to purchase the following parts: 6-volt BATTERY, LENS




                                                ASSEMBLY, SWITCH and an 0-RING. Model the following purchased parts:



                                                BATTERY, LENS assembly, SWITCH and the 0-RING. The LENS assembly consists




                                                of the LENS and the BULB.








                                                Your company will design, model and manufacture the following parts:




                                                BATTERYPLATE, LENSCAP and HOUSING.
