7. 1) Reproduce Desired Results 2) Not Physically Demanding 3) Fast Operation 4) Simple Operation for User 5) Low Cost

8. 6) Easy to Clean 7) Easy to Repair 8) Easily Transportable 9) Variable Silo Size 10) Easy to Store

9. The apparatus should be able to: 1) Pass though a doorway 2) Be moved by 2 people 3) Pack faster than Kung’s methods 4) Give a proper sink distance 5) Be built for under $500

19. Straight ExtruderTapered Extruder Extrusion Family

20. Gravity Fed PistonHand Fed Piston Horizontal Piston Family

21. Piston with Vibrating Chute Crank Slider Vertical Piston Family Screw Fed Piston

22. Centrifuge Weight Press “Other” Design Family Blower

23. Experiments Types: Effect of Lips and Sudden Changes in Diameter Effect of Plunger Size on Packing Effect of Piston Orientation – Vertical and Horizontal Silage Behavior on Chutes and in Ramps

24. Low Rated Concepts Extruder Family: Cost metric too high Lack of experimental data Horizontal Piston Family: Change in Pressure Per Layer metric too high Time to Fill metric is too high Jamming problems inherent in the design

25. Low Rated Concepts “Other” Family: Pressure target is not met Dimensions outside of constraints Weight outside of constraints

26. Vertical Piston Family: High Scoring Metrics: Pressure per layer Change in Pressure per Layer Time to Fill

27. Screw Fed Piston Evaluation: User Actions is low Time to Fill is low Cost of Screw Feeder is too high

28. Piston with Vibrating Chute Evaluation: Clogging problems increase time to fill Cost metric is too high

29. Crank Slider Evaluation: Time to Fill is good. Low Cost User Actions is high.
