  2. The Automated Gang Lock • The system uses a heavy duty 45 pound-force solenoid.

  3. The system fits in the narrowest boxes • The mechanism fits in a single box, protecting it from impact and corrosion.

  4. The module can be welded, bolted, or riveted in place • Can use mounting brackets, or can be mounted directlyto the box by the housing.

  5. Please wait while we open Windows Media Player

  6. A car-door style latch is employed to lock the bar in place • These latches are mass produced and can be bought for 5 dollars in large quantities.

  7. A rack and pinion design was explored. • An appropriate motor cost as much as the solenoid in the final design • The rack and pinion design also increased complexity and part count.

  8. Manual override must be locked out • An access panel can lock out the mechanism directly • Alternatively, a release mechanism can be keyed to the outside.

  9. Rivet Strength Calculations • Tensile Strength under moment force = 314lbs (FOS 2) • Tensile Strength = 1780 lbs (FOS 2) • Shear Strength =2600 lbs (FOS 2)

  10. Spring force calculations

  11. Cost Estimation • Articles shown in gray are conservative estimates

  12. The wireless controller is simple to integrate into the system • No wiring takes place inside the box after assembly • Wires can be run along with the lights • The receiver is specifically designed to work on 12VDC automobile power.

  13. Wireless modules cannot work inside closed metal boxes • Wireless signals cannot transmit through a conductive metal cage (Faraday Cage Effect). • The receiver can be placed outside the box • An antenna could be run to the outside of the box • The box itself can be made to act as an antenna.

  14. Wiring • Wiring the system is relatively straight-forward. • Each solenoid requires a relay to protect the wireless unit and to function reliably.

  15. Conclusions • Cost Estimate: • $45 per box in parts • $35 estimate labor costs per box • Final Estimated Cost for 3 box truck: $320 • Design uses mostly inexpensive manufactured parts • Can be installed in boxes large and small

  16. The automated system
