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”

IMPROVISED BROOM MAKING MACHINE

”INNOVATION MAY BE INSTANTANEOUS BUT, IMPROVISATION ISN’T ”

In my words, our team has clearly lived up to the above thought. We as a team have gone through a number of improvisations in the earlier proposed model of the broom making machine. We have continuously  adapted to the newer models as per the needs of the user.

Model 1:

Simple wooden bar with nails attached to it on which the broom is beaten.

Model 2:

Rotating nailed drum with hand and splitting the leaves

Model 3:

Attaching sewing machine pedal system to it.

But, today our mentor Prof.Anil Gupta suggested some improvisations and we have come up with a newer model of this machine.

 

Today’s concluded model:

Similar assembly with bicycle arrangement of pedaling to it.

At the start of the day, everybody was geared up for implementing their ideas into existence. After a lot of research and paper work, it was now time to actually bring their  innovative ideas into existence. The students were divided into proper idea specific groups and were allowed to go into the product details of their ideas.

This was followed by a meditative demonstration where all of us got a feel of a heavenly satisfaction and content. Even the lunch that we had after this exercise seemed very appealing and full of taste. It was a great stress buster for everyone present.

Then, all the ideas were brought to the final evaluation stage wherein the feasibility of implementing them was checked. Some, processing related problems were discussed. This was necessary for giving the students a clear idea of the process involved in the fabrication.

After this, the students actually started making the near working models of their ideas. All these models were made from the cardboard, stationery and waste papers etc obtained in the vicinity the sristi campus. During this, we made  certain improvisations in our projects of which we hadn’t thought of earlier.

Mr. Sheetal Panchal surely was a great company to all of us. He is a personality worth meeting atleast once in every innovator’s lifetime.  The time we spent with him will be definitely remembered by each one of us for decades to  come.

BRAINSTORMING INTERACTION WITH PROF.BHASKAR BHATT,IIT GANDHINAGAR

June 19th, 2013 proved out to be a very encouraging day for all the student innovators present at the summer school.
The out of the box thinking which Prof. Bhaskar Bhatt, IIT,Gandhinagar had successfully imparted to the students has certainly added a new dimension to their approaches. With his technical and managerial know how and extraordinary oratory skills, he left everybody spellbound.

The various analogies given by the professor definitely qualified to help the students in developing something concrete out of their primary notions. The various models thought of by the students were hereby discussed and expert opinions were  received in return. The idea of developing a balance between quality and cost efficiency of a product was planted into the minds of these young innovators.

Today’s session would surely sinter the green prototypes proposed by the students. This would no doubt serve the purpose of eliminating child labour in today’s world.
