INITIATION

The journey started with identifying the problem of the people involved in broom making. For the first few days, we met the people residing on roadside who make brooms and sell them in local market. We were staggered by their problems. Some of their problems that we found are as follows:

  • The posture: they had to continuously sit on the floor in an uncomfortable posture. This is responsible for them experiencing pain in the back, thighs and arms as well.
  • At a time, only one broom can be made.
  • Also, the action of beating the broom for splitting the leaves is quite a troublesome.

    SELECTION OF A PROBLEM TO WORK UPON

    There are steps in broom making.

    1. The huge date stem like leaves are cut from the tree and brought at the place of broom making.
    2. The leaves are segregated from the stem and tied in a bundle.
    3. The handle of the bundle is covered with rubber strips (generally tubes of bicycles) so that it is easy to hold.
    4. The tied leaves are beaten on the pointed nails of the conventional tool till the leaves are properly split.

    Out of these four, we have improvised a pre-existing machine for the fourth action i.e. for leaf splitting

  • IMG_2851STUDY OF THE REALITY: GROUND TRUTHINGHere are several factors which we had compiled so as to reach to the depth of the problem faced by the broom makers.
    • Posture
    • Number of brooms made per day
    • Number of brooms sold per day
    • Need for producing more brooms
    •  Feasibility of working with both hands
  • DESIGN PROCESSRome wasn’t built in a day neither was our design. The final design is a result of several improvisations in the pre-existing one.The first model suggested by us was driven by the sewing machine mechanism.

FINALLY FABRICATED THE DESIGN. . not to ignore the point that there are still many improvisations to be made.

FEEDBACK OF FACULTY ON THE MODELS, PEER CRITICISM AND REDESIGN OF THE DEVICES AND POSTPONING OR ABANDONING SOME POSSIBLE DIRECTIONS 

According to the feedback received by the faculty, we were advised to resume to the sewing machine pedal mechanism, but when we consulted our fabricator, he said that bicycle driven mechanism was suitable for this one.

Also, the experts had advised us to place only 1 drum instead of two; we enquired this with our broom makers whom we were in continuous touch with. They said that they could work with both hands. Thus, we adhered to our design.

We added another adjustable idle gear like structure so as to smoothen the pedaling operation. Also, a rod in  the center as a support was introduced. IMG_3183

My entire journey at SRISTI could be summed in what Robert Frost has once quoted:

“THE WOODS ARE LOVELY DARK AND DEEP,

BUT I HAVE PROMISES TO KEEP;

MILES TO GO BEFORE I SLEEP, MILES TO GO BEFORE I SLEEP”
