EFFECIENT MASS TRANSPORTATION

Group meetings and Discussion

1. 1st March, 2010- 4. 30 p.m.

We formed a group consisting of the seven mentioned members and tried to decide on the topic. 3 members researched on alternate fuels,2 on mass transport and 2 on space research. As we were not able to get much information and ideas regarding alternate fuels and space research,we combined it and finalized on Mass Transport.


2. 8th March,2010- 4. 30 p.m.

Based on our meetings with Dr. D.N. Rao-Prof.-Dept. of Chemistry, M.S. Ramaiah Institute of Technology, and Dr. Ravikumar-Dept. of Solid State Chemistry-IISC, we decided to go ahead with improvising the existing mass transport system and making it more efficient. Creative ideas pooled and one of the ideas was BRAIN!!


3. 15th March,2010- 4. 30 p.m.

We started our work on PDS. The distribution of work was based on the skills and abilities of the team members. We also consulted one of our parents regarding the materials used in the construction process. Complete information gathering on all the topics of PDS.


4. 22nd March,2010- 4. 30 p.m.

The skeleton of the body of the PDS was completed. Since the whole process is iterative in nature,the concepts,materials used etc were revised and the PDS was further improvised. The fuel was changed from electricity and magnetism to hydrogen fuels so the PDS process was repeated.


5. 29th March,2010 -4. 30 p.m.

We submitted the PDS and started with our work on the sketches which were submitted the following weekend. Sketches work given to skilled artists and no computer work done as the member was staying on hostel and wasn't much comfortable with computer scale diagram software.


6. 5th April,2010- 4. 30 p.m.

We held a brainstorming session and the pros and cons of the collective thoughts were analyzed. Using the different methods like criteria ranking, DAYTUM and EVAD methods,the concept of using hydrogen as fuel and roadways as the means of transport was finalized.


7. 19th April,2010- 4. 30 p.m.

We had a discussion about the Detailed Design Process-Ergonomics, Aesthetics and the Technical aspects. Scale drawings were discussed. The scale modelling was discussed. Discussing about report on meetings and group discussion.

Generally all the meetings held in front of the class. The meeting duration is about half an hour. Proof like pictures are present. The above information provided about all meetings are true to extent of our knowledge.

EFFICIENT MASS TRANSPORTATION

REPORT-6 ( DETAILS ABOUT CONCEPT SELECTION)

SELECTION OF THE TOPIC:

Primarily the idea of choosing the topic ‘Alternate Fuels’ was suggested by [NS] and agreed by all the other members. As the other group had chosen this topic and submitted paper work regarding the project we droppped it.

An idea about doing a project on ‘Space Research’ and 'mass transportation' was proposed by [SMM] and [RR] respectively. After realising that both the topics didn't work well with the team, thought collectively about efficient mass transportation. Team members couldnt connect themselves with space travel but as many of the members use bus for travelling they encountered with problems easily and came up with solution.

A good number of ideas were pooled in and we finally decided on efficient mass transportation as our topic.

TYPES OF TRANSPORT:

The idea of using bus as our mass transport was proposed by [AK]. As bus is already existing solution, it won’t be of any help and therefore the idea was opposed by the [SK] and [NS]. So the improvisations were made in bus like implementing movable seats for driver by [PB], air-conditioners by [SMM], putting engine at the back by [NS] and ramp for wheel chairs by [SK].

[NS] surfed the net about a high class school bus with all the facilities which ultimately inspired our model. Apart from this, ideas used in train was also incorporated in our mass transport like having two compartments, separators, emergency breaks and separate doors for each compartment and the idea of adopting ideas from train was given by [SMM].

With The combination of ideas from bus and train we named our mass transport as ‘BRAIN’.

KIND OF FUEL USED:

The idea of using electromagnetism to run the vehicle was given by [PB] ( referring to an article in a kannada magazine).

The idea is that conversion of mechanical energy to electrical energy. The idea was when the passengers walk on the floor of the bus with a special kind of instrument on them it converts energy and stores in the form of electrical energy. This was the source of energy for the vehicle.

But this idea was opposed by [AK] and [SMM] as it is practically inconvenient for passengers to wear the instrument everytime they travel and hence this idea was not implemented. Existing fuels like petrol, diesel, natural gas ideas suggested by [AK], [SK] and [RR] respectively but the idea was opposed by [NS] because the cost would rise up drastically keeping in mind about our needs in our mass transport.

Later we came up with an idea of using hydrogen as fuel after consulting our chemistry professor Dr.D.N.RAO and IISC prof which was convincing for all the team members as it had more positive points over other fuels therefore was used as fuel in our mass transport.

Alternative Fuels-Progress Report 3

Uptil this point, we were bent upon using dry ice and wind energy dual-fuel as our main energy source. But, when we take it in the practical sense, it doesn't seem feasible since the particle accelarator is larger in size than that of a normal vehicle. And wind energy has now taken a back seat, since the breadth of the car would increase two-folds and also since there were practical difficulties encountered while trying to have openings for the wind tunnel in the car. Solar energy generation is being given second priority and might be considered as a supplementary fuel system. Now our focus is mainly towards selecting a particular element which gives a high rate of combustion and develops high pressure when combusted, so as to increase the velocity of the flywheel. Simultaneously, we are working towards finding a practical way of harnessing wind energy so as to use it as at least a supplementary source of energy if not the primary one. We are comparing energy densities of various fuels and the emissions from each of them in order to bring the efficiency to the maximum possible level without endangering the environment and our ideal final design would be one which could aesthetically combine our various ideas into a single product.

Efficient Mass Transportation

Report-5

EMBODIMENT PRINCIPLES
Optimization: The criteria like putting rods in between, making use of solar energy for running the vehicle etc should be compromised upon to get the final product of desired features.

Simplification: The vehicle is simplified by placing the engine behind , for two reasons:
a. In order to avoid the heat coming from the engine, thereby making the driver comfortable.
b. In order to provide more space for the passengers to enter and exit.
c. As the hydrogen fuel is used, the engine is more simplified than the normal engine

Aesthetics: This is about the visual appeal of the vehicle. In order to attract the passengers , the following aesthetical aspects can be taken care of:
a. The vehicle should be painted with appealing harmless colors.
b. The vehicle should be provided with the air conditioners, comfortable seats, the bus floor should be carpeted, the windows should be provided with the curtains and the ramp should be provided to move the wheel chairs.

Ergonomics: An user friendly design should be made.
a. After many years of driving, the drivers might suffer from health problems like back pain. Hence comfortable seats using materials like cushion etc. are to be provided.
b. For the passengers in standing, vertical rods and holders on the top are to be provided.

Synthesis: A combination of techniques and elements are used in order to arrive at the solution. In the mass transport which we are concerned, various techniques like engine is placed at the back of the vehicle and elements like hydrogen fuel and eco-friendly engine are used.

Iteration: After each stage of the design, the progress towards the making of the product is done. By doing the process, from the product design specification(PDS) up to the stage of design and checking, simplifying and modifying the required factors in the process all over again will improve the final product .
