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”

Interaction with mason

We went to a construction site for reinforcing a concept of wall making machine and ask him about feasibility of this machine.

Then we fixed all the dimensions and specifications according to need and requirement of him.

Idea generation to the Fabrication

Its the 13 working day of this summer school participants with the great efforts of our mentors and professors from various fields. Finally now we are ready to start the fabricating process after the model making and modifying processes. Although there are various modifications which can be still done as nothing is perfect, but we are trying to give our best.

Today we are approaching to various fabricators in the city to seek some help. It has been a very good and new experience to us from which we learned right from the idea generation, market survey, brainstorming to the designing, model making.

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.

conventional bar type Model 1

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.

Hello friends,

This design is based on the concept of see-saw operation. There is a platform which may be inclined towards the ground and will be lifted by the pedal given at the leg-side of the user. When the user pushes the pedal, the wastage collected over the platform will directly be gathered into the bag .

The bag is mounted on the circular frame ; which can shrink manually; this enables to un-mount the bag when it filled up and mount another one.

There are flaps attached at the front side and the control of that flaps are given on the handle by which the user is moving the whole wheel barrow. This may give the ease in operation.

In its operation user moves the barrow towards the garbage pile and when one feels like to have enough garbage over the platform he would push the pedal and thus the garbage will slide into the garbage bag mounted on the shrinkable frame.

Easy in operation, good balancing, good volume of wastage can be handled with this equipment…

Thanks!

Modifivation in Sugarcane Machine

SUBJECT: MODIFICATION IN SUGAR CANE JUICE MACHINE BY WHICH ONLY ONE PERSON CAN MAKE JUICE OF SUGARCANE & HENCE CHILD LABOUR CAN BE ELIMINATED . .
.
Team Members : 1) Purvesh Dodia 2) Bhagirathi Dodia
.

In normal sugarcane machine 2 person is required to make the juice of sugarcane. One person in Inlet side and other is in another side. Generally children are used at sugarcane lorry. So thousands of children are present at sugarcane lorry. .
.
So we analise this things and first we design curved portion in outlet side of sugarcane juice machine. Eventually we modified our design after taking valuable guidance of Prof. Anil Gupta, Prof Bhaskar Bhatt, Mr Varia Sir etc. After that Finally we make the that curved element. .
.
After that we fixed it in actual Sugarcane Machine & it works. Sugarcane automatically came back from curved portion. Sugar Cane shop keeper also satisfied & he is ready to assemble it . .
.

There are Many benifits of it like. .
1> Child Labour Can be Eliminated
2>Income of Poor Sugarcane Lorry Man can be increase.
3> Only 1 person can perform same operation.
4>Low cost
5> Easy to manufacture.

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.

VISIT TO LOCAL BROOM MAKERS

JUNE 20, 2013

Today seemed to be more of an exposure day for 3 of us ( me, Rupesh and Anshul).

To understand the problem of the conventional broom makers, we visited the local broom makers of the city. There we had a clear idea as to what exactly the broom makers and their family members have to face. Right from making segregating the palm leaves to the actual process of broom making; all was seen by us. This healthy interaction proved to be interestingly strong in   giving us the knowledge which we could not gain from the existing theoretical or e-sources.
