Work Experience
Product Designer & Developer
IIT-Madras Chennai, India Autumn 2004
I worked in a team of four to develop a complete product architecture which included Quality Functional Deployment (QFD), conceptual design and evaluation and embodiment design for eight products, as a term paper.
As a team we were required to first go through the tedious procedures of customer need analysis, for which we conducted surveys throughout the campus.
With a sample size of 15-20 for each product, we were able to get good results. The needs in mind specifications for each product was decided and a complete QFD chart was prepared using QFDCapture

After the QFD, we followed a completely structured design approach for developing concepts for the products. Functional decomposition was done and product vectors were generated for all the eight products, following which a rigorous concept generation was done for two products. We evaluated each concept thoroughly using decision matrices and TRIZ approach.
The final selected concepts were modeled and CAD drawings were made using ProE 2001:

Battery operated toothbrush (Exploded View)
Household Dishwasher (Assembled View)

Design of Handicap Friendly Rail Coach
Vidyasagar Chennai, India Autumn 2003
I Worked with Vidyasagar (ex Spastics Society of India) to design a Handicap Friendly Rail Coach which was officially proposed to the Indian Railways.
It started with an on the spot design contest, for which my design was adjudged the best, and went on to become a month long project with Vidyasagar.
The work was to design the interior layout of a railway coach so as to make it accessible to the physically challenged. I also provided a scheme for integrating the coach in mainstream railways operations.

Summer Intern
Hero Honda Motors Ltd Delhi, India Summer 2004
As an intern I was attached to the Tool Engineering department in Hero Honda Motor Ltd (HHML)
I was assigned the project on Predictive And Preventive Tool Change and TPM Activity on Cylinder Head machining line (shopfloor). The first phase of the project required me to prepare a list of tools and their actual life on the m/c line. Once the tooling list was prepared a software was developed in collaboration with the IT Department of HHML, which used the tool life data and predicted the appropriate tool change date for each tool.
The second phase was to implement Total Preventive Maintenance on the Cylinder Head m/c line with respect to the Tool Engineering. It was found that the major cause of down time was the tool change procedure, for which I suggested various solutions.
1. Independent toolboxes for each machine.
Toolbox with Shadow board
Toolbox fixed on to the machine
2. A calibrated height setting gauge for drills.

Vortex Engineering Pvt. Ltd Chennai, India Winter 2003
My work at Vortex Engineering was to research existing technology available in Automatic Teller Machines (ATMs) and hence help in designing a new low cost ATM.
The task included extensive patent database searches and assessment of the various technologies used in an ATM concluding in a final report on existing systems and mechanisms in present day ATMs.
