  12. 12. Design of operator’s area of TAFE tractor for 2015 INTRODUCTION Tractors are definitely a special species in the world of Automobiles and multipurpose vehicles. I am always interested to explore Tractors and apply innovative design principles to them. There is a lot of scope for intervention of Industrial Design in Indian Tractor. ABOUT TAFE(Tractors and Farm Equipments Ltd.) I am fortunate to attain a right platform to explore this field during my internship at TAFE. During my Internship, I was given an opportunity to study the evolution of TAFE product styling and compare it with that of the competitors. As an extension of my internship study, I was given an opportunity to takeup my Thesis project in the field of Tractor in collaboration with TAFE. After studying the form evolution of Various Indian tractors, I was interested to explore the possibilities of elevating the comfort, aesthetics and user experience of driver’s workspace of Indian tractor to develop an wholistic knowledge of a tractor design by combining the external styling and interior- operational comfort. Considering the evolution of Tractor design on International basis and incresed demand in Indian market, Indian tractor is going to experience a design evolution in the coming future. This provoked me to takeup this project to Design futuristic concpts for Indian tractor. considering the time span from conceptualization to manufacturing, 2015 is takenup as the year of target.THESIS PROJECT REPORT - CHAGANTIPATI GOKUL VENKATESH (M.Des 2009-11), IIT Guwahati 001

  14. 14. Design of operator’s area of TAFE tractor for 2015 My thesis project has got its base from my internship project at TAFE. In this chapter I have briefly summarized my work during internship period. Internship Brief: To study the evolution of form and various aspects of TAFE/MF tractors that make an appeal to the customer and compare with that of competitors tractors. INTERNSHIP Objectives: To study the form evolution of TAFE/MF tractors. To study the evolution of major competitors. To compare the present range of TAFE/MF tra- ctors with that of competitor tractors. To study the current trends in domestic and international designs.THESIS PROJECT REPORT - CHAGANTIPATI GOKUL VENKATESH (M.Des 2009-11), IIT Guwahati 004
  15. 15. Design of operator’s area of TAFE tractor for 2015 1.1 OVERALL EVOLUTION OF TAFE/MF: On the whole[Fig-1.1(a)], right from stubnose bonnet to style ‘G’ bonnet, there have been many changes in the styling that have taken Fig-1.1(a): TAFE evolution place during the evolution which were discussed earlier. One cannot find any drastic change taking place during the evolution. The identity of TAFE/MF is maintained through out the evolution. Some basic keywords that can be associated with TAFE/MF product range are like; Longish. Bulky. Flat. Reliable. INTERNSHIP Friendly. Strong. Power full. The styling has focused mostly on the feel part of the form and gradually through the evolution, expression is also being brought into the styling. This can be observed from evolution of key words related to expression like aggression and wild along with key words like flat and longish. The styling of TAFE/MF has its own identity in the market and it draws no similarities or inspirations from other existing product styling. But, the main focus of industrial design has TAFE/MF next generea�on only been on the hood. During further evolution this factor may be considered and the tractor as whole can be made more appealing. Designing all the products together as a whole will help in improving co-ordination and reducing visual noise.THESIS PROJECT REPORT - CHAGANTIPATI GOKUL VENKATESH (M.Des 2009-11), IIT Guwahati 005
  16. 16. Design of operator’s area of TAFE tractor for 2015 Fig-1.1(b): Identity Analysis During the evolution, the front grill underwent 6 many changes. In 1035 there were two columns of horizontal bars(1) and from that. they have slowly transformed to strong horizontal bars(2). These horizontal bars are further concentrated on and style ‘F’ kind of 5 expressive grill(3) came out. Finallyn this got entirely transformed and in style ‘G’ the front grill(4) is clean and fresh without any visual noise and lights have taken care of the 8 expression. But, this has given up the identity maintained by TAFE/MF. 1 Lights also underwent changes during the evolution, the round lights(5) which used to pop INTERNSHIP 4 out of the hood have slowly become the part(6) of front grill. Then these round lights further 10 transformed into rectangular(7) ones. This has 9 changed the pleasant expression of the tractor into a bit serious and masculine one. These rectangular lights further got transformed into sharp featured style ‘G’ lights(8). This shows 7 an indication that as being followed by the international trends, head lights might be used 2 by TAFE/MF also to make the products more appealing to the customer. 3 One can also observe that the products are being made more usable and presentable by decreasing the area of machinery being exposed. The package and compactness relatively increased. this can be observed from disappearance of air filter(9) and exhaust(10) from the external surface of style ‘G’. This is making style ‘G’ more clean and stylish tractor.THESIS PROJECT REPORT - CHAGANTIPATI GOKUL VENKATESH (M.Des 2009-11), IIT Guwahati 006
  17. 17. Design of operator’s area of TAFE tractor for 2015 1.2 OVERALL EVOLUTION OF MAHINDRA: 2 3 On the whole[Fig-1.2(a)], Mahindra is not reluctant in introducing drastic changes in styling during the evolution of its product range. During the each stage of evolution, there has been a considerable amount of change in the 3 styling of their products. Due to these drastic changes in the product styling, Mahindra could not maintain a partic- 1 ular identity for its design and there doesn’t seem to be any Mahindra kind of styling existing. But. they have done quite well in maintaining certain features through out their styling evolution which keep up their identity. INTERNSHIP One can observe that the cut - 1 shown in blue can be seen in all the products of Mahindra. All the products have front face(2) in the form of vertically oriented rectangle. The wide horizontal slots(3) in the front face have gained the liking of many Indian farmers and these slots have formed an identity for Mahindra Fig-1.2(a): Evolution of Mahindra during the evolution till styling ‘F’ has come into the scene. How ever, Mahindra seem to be following benchmarking strategy in styling their products. Most of their lower and medium HP tractors seem to have some inspiration from TAFE/MF and higher HP versions seem to have some inspiration from John Deere. They are always trying to catch-up the global trends and seem to be keen in making changes to adopt to the rapidly changing global trends.THESIS PROJECT REPORT - CHAGANTIPATI GOKUL VENKATESH (M.Des 2009-11), IIT Guwahati 007
  18. 18. Design of operator’s area of TAFE tractor for 2015 1.3 INTERNATIONAL TRENDS: In international market, Tractor design and 3 Styling is advancing at a very healthy pace. Most of the international designs are focusing on user needs and comfort to achieve user centric design. In Fig 1.3(a), one can observe that tractor is not just considered as a machine. Tractor is 4 being made as stylish as other automobiles 4 and as comfortable as luxury cars. 4 One can also observe that the evolution of electronic and sophisticated controls from the 1 early controls shows that farmers are also2 INTERNSHIP turning intelligent and are ready to handle technology to work smartly for efficient out 4 put. The fact that tractor is no more considered as just a machine in international market can be exemplified by how the latest hoods(1) are covering/packing almost all the components, how the fenders(2) are being used to cover the front and rear wheels along with the most important development like evolution of lux- urious cabins(3). All these examples just show that tractor is definitely being considered as a posession and Tractor manufacturers started consider user requirements and his/her tastes before designing these wonderful machines. There is also considerable development in the usage of different materials and combinations. Lights(4) are also being used as important Fig-1.3(a): New Holland Tractor elements of of overall design THESIS PROJECT REPORT - CHAGANTIPATI GOKUL VENKATESH (M.Des 2009-11), IIT Guwahati 008
  19. 19. Design of operator’s area of TAFE tractor for 2015 Lights of tractor are under going drastic changes from time to time with the evolution of tractor. Lights have become a major part of the Fig-1.3(b): Few International Models identity of a tractor. Different manufacturers are 2 using different style lights to create their own 2 identity. On a whole, one can observe that there are three basic types of lights in international tractors with advanced design. The first type being expressive lights(1) where the lights are more sharp, curvy and organic in shape close to the shape of eyes of real living thing. Lights are generally treated as eyes of the vehicle by industrial designers. We can observe that INTERNSHIP these kind of lights are already entering domestic Indian market. Here one can observe that New Holland confidently used their lights to enhance the expression and these are definitely extracted from the elements of eyes3 from cat’s family. The other type being long rectangular, horizon- tally oriented lights(2) which are giving strong outlook to the vehicle. 1 Third one being multiple lights(3). In this kind of lights, many lights are used together in different patterns to intelligently use them as a part of visual identity of the vehicle. The lights of type 2&3 might do well in domestic market as these have a strong outlook and gives a notion of getting ‘more’ which suits the Indian attitude of possessing big things.THESIS PROJECT REPORT - CHAGANTIPATI GOKUL VENKATESH (M.Des 2009-11), IIT Guwahati 009
  20. 20. Design of operator’s area of TAFE tractor for 2015 Companies in international market are keen in forming an identity for themselves. This 6 1 seems to be a gesture extracted from luxury 1 car industry. BMW is an example for that where they never change the design of the front grill of their vehicles. This forms an identity for BMW and people can recognize a BMW from a 2 distance. 2 In the same way Tractor manufacturers are also trying to go for having their own identity. To exemplify, one can observe that New Holland is maintaining similarities in front grill(1), its lights(2) and the slope(3) towards the front of the hood. In Lamborghini tractors INTERNSHIP we can find that this identity is invisibly and Fig-1.3(c): Trend Analysis sensitively maintained. Lamborghini maintains the similar form in its tractor hood. There is a 4 line(4) which cuts the front most region of the 5 hood. A horizontal strip(5) are some things which are maintained in common and highlights 6 the identity of Lamborghini. 5 On a whole, one can observe that the new 4 generation of international tractors got rid of the blunt boxy kind of look and evolved into a well designed forms with many curves and lines. Most of the tractors are coming with slopy hoods and as the complete coverage of internal components has almost become common in international market the openings in the hood(6) for air circulationa and cooling purpose have become part of design and they are being well utilized by the designers.THESIS PROJECT REPORT - CHAGANTIPATI GOKUL VENKATESH (M.Des 2009-11), IIT Guwahati 010
  21. 21. Design of operator’s area of TAFE tractor for 2015 Tractor manufacturers in international market are using colours in an intelligent way to stand out in the market. Colour is one of the major assets for John Deere and New Holland. Fendt of Agco group is good in their designs which l are competitive and they are launching vehicles with different colour versions. Manufacturing of vehicles with customers choice of colour might become common in future just like it is in the case of Car and Bike industry. Tractor industry is also keeping in pace with other automobile industries interms of technology usage and development. Tractor manufacturers are using different materials and INTERNSHIP modern sensitive technologies to keep them selves upgraded with the latest evolutions. New Holland has the technology of Hydrogen Fuel cell tractor and they have concept design for it. Just like other advanced automobile industries, International tractor industries are always trying to have future concepts for their backup and with the growing competition in this sector, concept designs make the companies feel secured and go ahead in global competetive markets. One can also observe that all the controls and products in the operators area of the tractor are evolving as per customer needs and these are also being given importance just like the importance given to interiors in car design.

  30. 30. Design of operator’s area of TAFE tractor for 2015 4.1 EXPLORATION: 4.1.1 Self Exploration:. As I have mentioned earlier that tractors are a new species of Vehicles with which I had very minimum interaction. During my system study phase, I started with exploring the tractor by trying to understand the way to use it, with out any external guidence. I started with this inorder to develop a better understanding of the work space and the level of communication it provides to the users. During this process, I could identify and Fig-4.1.1(a): Self Exploration observe many minute aspects in the SYSTEM STUDY workspace which influence the usage pattern to a great extent. 4.1.2 Interaction with Drivers: Fig-4.1.2(a): Interaction with Drivers After going through self exploration, I started interacting with users/drivers who are actually using the existing workspace of Indian Tractor, to under stand the actual usage pattern being followed by the users and to understand the level of understanding amond the users and the level of communication, workspace is providing to those users. In this process, I discussed about the problems users are facing with the existing workspace and the kind of improvements they are expecting. Afetr completing these two explorations, I could understand the function of each and every control existing and the way to use those controls.THESIS PROJECT REPORT - CHAGANTIPATI GOKUL VENKATESH (M.Des 2009-11), IIT Guwahati 017
