Project Description Requirements Compatible with medical machines Support clean-room cover Reduce shock during transport Minimal X-Ray interference Compliant with X-Ray machine Dr. Becker’s X-Ray Machine Clean Room Hood Kenyon Rowley, October 7, 19F5 - Aneuvas Tech Portable Bench 2
Project Description/ Concept Generation How Concepts were Generated Three Parts • Wheels/Shock Absorption • Tabletop • Storage Hunter Daniel, October 7, 19F5 - Aneuvas Tech Portable Bench 3
Black-Box: Wheels Reduced Impact Material Less Noise Force Shock Absorption Easier to Push Design Better Turning Hunter Daniel, October 7, 19F5 - Aneuvas Tech Portable Bench 4
Decomposition Model: Wheels Expensive Instant Shock Absorption MRF Dampener: Too Expensive/ Complex Requires Actuation Complex Shock Absorption Easy Installation Pneumatic Tires: Constant Absorption without Simple Design, Actuation Cheap Inexpensive Hunter Daniel, October 7, 19F5 - Aneuvas Tech Portable Bench 5
Raised Spill Guards Wood Black-Box: Tabletop Up to ½ Inch Raised Platforms Contain Spills Grooved for Hood Base X-Ray non-interference 26” Wide X-Ray Machine Compliant Material Zipties Protect Machines from Spills Design Support Hood Polycarbonate Fit Through Doors Big Enough Workspace Cord/Wire Guidance Drainage Kenyon Rowley, October 7, 19F5 - Aneuvas Tech Portable Bench 6
Decomposition Model: Tabletop (1) Easily Cleaned Raised No Tilt Platforms: Client Spill Guard Preference Restricted Work Area Protect Machines from Spills Drains Loose Liquid Drainage: Containment of Loose Liquid Unnecessary Drainage Difficult to Clean Performance Tilt or Interruption of X Rays Kenyon Rowley, October 7, 19F5 - Aneuvas Tech Portable Bench 7
Decomposition Model: Tabletop (2) Uninterrupted Transport Less Obtrusive Holes in Table: Stored Machine Spill Guards Around Vulnerability Directly Next to Workspace Cord/Wire Spills Through Table Guidance Adaptive Zip-ties: Removable Client Preference Already Designed in Hood Keeps Cords out of Spills Kenyon Rowley, October 7, 19F5 - Aneuvas Tech Portable Bench 8
Black-Box: Storage Wood Material Flanges Storage Design Drawer Dimensions Kenyon Rowley, October 7, 19F5 - Aneuvas Tech Portable Bench 9
Decomposition Model: Storage Less Maneuverability Stable U-Shaped: Too Bulky Client More Storage Preference: U-Shaped with Storage Desk One Drawer Easy Access Drawers: More Access Maneuverability Kenyon Rowley, October 7, 19F5 - Aneuvas Tech Portable Bench 10
Concept Generation: Shock Absorption ● Initial idea to implement MRF. ● Instantaneous shock absorption. ● Dr. Becker suggested this MRF Dampner concept may be to complex for the need. ● Went with simpler and cheaper pneumatic tire design. Hunter Daniel, October 7, 19F5 - Aneuvas Tech Portable Bench 11
Concept Generation: Tabletop ● Initial idea to make entire tabletop flat. ● Dr. Becker suggested we add in raised platforms on the sides. ● Increased stability and easier to clean if spills occur. ● Existing Polycarbonate piece for middle. ● Slots for hood to slide in. Kenyon Rowley, October 7, 19F5 - Aneuvas Tech Portable Bench 12
Concept Generation: Storage ● Initial idea to make U-shaped storage. ● Simple storage solution. ● Drawers that pull out instead. ● U-shaped storage with drawer on one side. Kenyon Rowley, October 7, 19F5 - Aneuvas Tech Portable Bench 13
Concept Selection: CNs and ERs Customer Requirements Engineering Requirements Engineering Requirements Durability Cost Reliability Weight Safety Volume Maneuverability Yield Strength Inexpensive Spring Constant Aesthetic Deflection Multi-purpose Thickness Lightweight Temperature Hunter Daniel, October 7, 19F5 - Aneuvas Tech Portable Bench 14
Concept Selection: Decision Matrix Hunter Daniel, October 7, 19F5 - Aneuvas Tech Portable Bench 15
Concept Selection: Wheels ● After evaluation through the decision matrix as well as guidance from Dr. Becker, the pneumatic tire design was chosen. ● The design is much simpler and cheaper than the MRF dampner but Pneumatic Wheel offers adequate shock absorption . ● It will be easily installed to the bench design.

Budget Planning: BOM ● Tabletop (polycarbonate and another polymer/wood) ● Legs (wood) ● Pneumatic Tires ● Storage shelf (wood) ● Drawer (wood) ● Drawer slides and wheels (metal/plastic) ● Storage Cover (polymer) Kenyon Rowley, October 7, 19F5 - Aneuvas Tech Portable Bench 22
Budget Planning Materials Overall ● Tabletop (polycarbonate): ● Materials: $60* $350 ● ● Spare Parts: Tabletop (polymer/wood): $50 $60 ● Legs (wood): ● Prototyping: $20** $200 ● Pneumatic Tires: ● Equipment: $100** $200 ● Storage shelf (wood): ● Contingency: $30** $190 ● Drawer (wood): $30** ● Drawer slides and wheels Total: $1000 (metal/plastic): $30** ** Prices based off McMaster-Carr [1] ● Storage Cover (polymer): $30 * Prices based off Grainger [2] Kenyon Rowley, October 7, 19F5 - Aneuvas Tech Portable Bench 23
Conclusion ● Through concept generation and evaluation our team was able to decide on design paths for the bench. ● Shock absorption, tabletop, and storage can now be in the developing stage. ● With CAD designs finished, the next step is discussing these design ideas with Dr. Becker to confirm his satisfaction and begin designing a prototype.
