Suggestions From Prof. Shashank Mehta

GROUP 1:

  • Reducing the size of plate so that the impact gets stronger
  • A single or multiple hammers that can hit the grooves filled with nuts.
  • Avoid using pressure mechanism as it is used only for big industries
  • Can try for vibration as the main concept of the device
  • Brushing (like against a wire mesh) mechanism for shell removal.
  • Avoiding any automation

 

GROUP 2 and 3:

Plucker

  • Make the Handle of less diameter and plucker part of big for good grip and easy handling.
  • Make collector part short and use a rod (not a collector) as the handle.
  • Find most effective shape for plucker (Brute force).
  • Try using some bag for collecting (Comment taken back later).
  • Don’t use complex designs (Use easily available components).
  • Reduce human contact with the force (Easy transferable of fruit to containers etc)

Processor

  • Try using a cylinder instead of box
  • Avoid putting thorn removal inside (or with) the plucker (Increases complexity and reduces Handling).

 

GROUP 4:

  • Attach a fixture to hold the broom so that the user has to just rotate it by resting the broom on the support.
  • Squeeze the mechanism by removing the chain and directly attach the sprocket to the other 3 links
  •  Leg operated device though a better design would make the existing device bulkier and complex. This could be looked into later but focus on improving the current hand operated device
  •  Simplify the design by removing the redundant links, fixtures so that a part of the device could be fabricated by the broom makers themselves from the locally available parts. The device then could be make as a portable tool which the users can carry along with them.
  • Attach sprocket­crank on the other side and remove the gear ratio Feedback from Shashank Mehta on Broom making device

  • Attach sprocket­crank on the other side and remove the gear ratio

GROUP 5:

  • Use of simple mechanism
  • Use of funnel depending on the size of  seed

 

GROUP 6:

  • Improve the current design

A reciprocating plate that fits into the groove and and hence gets locked
