Subsystems Load napkin Dispense silverware (separate one fork and one knife) Deposit silverware onto napkin Wrap silverware and eject finished product

Napkin Loading Wire Claw Straps attached to napkin

Napkin Loading Technique(+)(-) A. Wire Claw Doesn't require napkin modification May drop napkin Fairly inexpensiveMay rip seam or tear holes Wire could bend Napkin must have lip B. Add straps/pockets to napkin Increased reliabilityMust modify napkins Less downward force Straps could break/ Pockets hard to clean

Silverware dispenser 1 Manual Loading Conveyor

Silverware dispenser 2 Top ejection (spring-loaded)

Silverware dispenser 3 Bottom ejection (gravity-loaded)

Silverware Dispensers - PMI Technique(+)(-) A. Manual Loading Conveyor Guarantees 1 fork & 1 knifeMust individually sort and load Eliminates mechanical separation of silverware (increased reliability) Requires motor and programming Size Must manufacture cleated belt (cost) B. Top Ejection Eliminates manual separation (greater convenience) Requires spring - potential for wear More compact than A.High tolerances needed for spacing Saves height compared to C.Deformation of silverware may create jam C. Bottom Ejection Eliminates manual separation (greater convenience) More friction on silverware due to increased normal force More compact than A.High tolerances needed for spacing No springs neededDeformation of silverware may create jam Can load from side

Deposit Silverware to Napkin Direct Drop Pivoting arm Sliding box

Deposit Silverware - PMI Technique(+)(-) A. Direct Drop SimpleCould interfere with other systems Inexpensive Limited control of silverware placement No additional system requirements B. Pivoting arm No external power Must have precise end mass to drop only with knife and fork Accurate placement of silverwareArm must have very little friction Does not interfere with other systems C. Sliding Box Accurate placement (best of three)Requires controls Does not interfere with other systemsComplex

Wrap Silverware Spinning fork

Wrap Silverware Sushi Roller

Wrap Silverware Silverware bouquet

Wrap Silverware - PMI Technique(+)(-) A. Spinning fork Reliable and efficientPrecise placement of silverware needed Tight rollMore complex ejection system than B. B. Sushi roll Integrated ejection Uncertainty in performance (neatness and tightness of roll) Fewer motors needed C. Bouquet No rolling necessaryUnusual design may not be accepted by customer Potential napkin loading issues Requires restaurant to purchase, clean, and store rings
