  1. 1. Shubham Garg Mechanical Engineering, University of California, Berkeley Engineering Design Portfolio 4400 Memorial Dr, #2236, Houston TX| 510-697-9492 shubham.garg@berkeley.edu shubhamgargdce@hotmail.com
  2. 2. CONTENTS MINI BAJA RACING AN ALL-TERRAIN VEHICLE PROJECT EXO-KNEE ROBOTIC INDUSTRIAL KNEE SMOKESCOPE 5 CENT SMOKE DETECTOR WINE & WINE DESIGN CHALLENGE WINNER HELMET DESIGN CAPSTONE PROJECT FRUNGE SMART SPONGE CASE DORA MOVE, EXPLORE AND GIFT HABITATT ELECTRONIC TATTOOS FOR EMOTIONAL WELLBEING
  3. 3. BAJA RACING All-Terrain Vehicle INSPIRATION When the road ahead is not that smooth. This project aimed to deliver a single-seat, off-roading vehicle for a weekend off-road enthusiast Image Source: Amilton Reis
  4. 4. Genesis Delhi College of Engineering 2009-2012 “Mud, Sweat and Gears” BAJA Racing Mini-Baja is a collegiate design competition sponsored by the Society of Automotive Engineers. The team’s goal was to design, build, test, promote, and compete with a prototype of a single seat off-road vehicle
  5. 5. Define and Design • Vehicle was designed around the driver needs and ergonomic requirements • Using driver feedbacks, iterations were performed to deliver better ride performance • Material Used : AISI 1018 seamless tubes • Achieved weight reduction of 10.55% compared to previous year
  6. 6. Suspension Design • Independent double wishbone suspension linkage configuration was used. • Front Uprights designed to withstand bump loads and breaking torques with a FoS of 3.5 using EN 24 • Rear Uprights Designed to withstand bump loads with a FoS of 1.6 using Aluminium 6063 Skills Honed: • Solid Modeling • FEA Analysis • DFA & DFM • DFMEA • Prototyping • MIG Welding • Lathe and Milling • Drilling • Team Management • Leadership • Logistics and PR
  7. 7. HABITATT Electronic Tattoos for Emotional Wellbeing INSPIRATION One effective way to treat mental illness is by helping patients rewire their existing, negative patterns into positive, new ones. Habitatt empowers users to interrupt negative thought patterns and replace them with positive ones. Image Source: http://www.loveyourdesign.com/
  8. 8. HABITATT Ideation • We were interested in looking into the mental health space, and were specifically fascinated by how we might bring habit- forming behaviors to wearable space. • We brainstormed types of habits that we could encourage such as reminding kids to brush their teeth but once we settled on taking up individual’s mental health, we brainstormed several interactions with tattoo. Prototyping & Working • Habitatt consists of three different layers on the skin. The layer closest to the skin is an insulating layer, designed to help mitigate noise readings due to the natural conductivity of the skin. • The next layer consists of conductive ink, joined to wiring via copper tape. This serves as the actual circuitry, which we can connect an Arduino and other components to. • The top layer is the art layer, or the visible tattoo design. Based on user interviews and independent research, we created a variety of designs symbolically associated with healing and well-being.
  9. 9. EXO-KNEE Robotic Industrial Knee INSPIRATION Assist user when squatting and be completely free in all other cases (standing, walking, walking up or down stairs) Image Source: Luis Miguel Sanchez
  10. 10. EXO_KNEE Robotic Industrial Knee • Coded Arduino Mega to read serial port data from two IMUs and actuate servomotor which in turn would trigger spring mechanism • Using IMUs, I measured real-time thigh angles to differentiate between walking downstairs and squatting (similar motion) Arduino position on Exo-knee Arduino and IMUs were programmed to actuate a servomotor when algorithm condition is met: IMU1 > -40 && IMU2 >-40
  11. 11. HELMET DESIGN Capstone Project INSPIRATION Over 1,000,000 high-school football players at risk of concussion injuries in long term Players experience about 5-10 tackles per game which are above 90 g acceleration (concussion calibre) Image Source: Nymag.com
  12. 12. HELMET DESIGN Capstone Project Concept • Formulated a R&D toolbox for a new entrant to Football helmet market. • The toolbox contains: Go-to market strategy, IP strategy, product lifecycle, modelling techniques and validation process. • Developed a simple CAD model of leading helmet which can be used in future to propose design changes. Skills Used: • FEA Analysis • DFA • DFM • Prototyping
  13. 13. wine & wine Design Challenge INSPIRATION To improve the experience of people in long-distance relationship by allowing them to share common activity Image Source: http://www.tiaratirr.blogspot.com
  14. 14. Concept Generation and Prototyping Tasks: • Empathy generation • Insights identification • Need finding • Design Solutions • Concept Sketches • User Feedback • Final Prototype
  15. 15. User Feedback and Final prototype “It is great idea for the type of couples who do stuff together like Skype dates and distance dinner dates.” - Adam Product A pair of synchronized wine glasses with real time display of the amount of wine in the other cup. Once the top-off button is pressed on a phone app, the top-off button will light up on your partner's glass indicating to them that you would like them to top off their wine glass.
  16. 16. DORA Move, Explore and Gift ! INSPIRATION Dora is a traveling gift-box, meant to encourage people to move and explore the space around them and spread a little joy in their community Dora comes with her own Twitter account and website where she pings and maps her current location for people to find her along with an opinion or interesting fact. Image Source: http://gothamgal.com/2013/12/gift-giving/
  17. 17. DORA- Design Phase Brainstorm Napkin Sketches Prototype User Feedback • Pinging Location • Reinvent purpose of a cart • Explore on foot • Random Acts of Kindness Design Space
  18. 18. TECHNOLOGY Arduino Laser cutting GPS Tracking Live TweetGPS BreakoutWi-Fi Shield Heroku • Once someone approaches Dora, she greets them and expresses her desire to go somewhere nearby. This was done with use of proximity sensor and on- board speakers • Once the destination has been reached, the user can pick a gift from the box which gets unlocked and leave behind a present for the next person to find. • All this was done using an Arduino + C3000 (Wi-Fi) + GPS breakout to tweet live location of Dora How it Works
  19. 19. FRUNGE Smart Sponge Case INSPIRATION Sharing a kitchen can be challenging as housemates try to manage their busy schedules and remember (or avoid) to wash the dishes. Seamlessly embedded into the interaction of washing dishes, Frunge allows housemates to leave each other messages which play back when another housemate comes by to use the sink. Image Source: https://loveinlufkin.files.wordpress.com/2013/05/photo3.jpg
  20. 20. FRUNGE Idea Generation • While brainstorming ideas and sharing pictures of our kitchen, we noticed that we all had roommates that did not pick up after themselves. • So, we wanted to create an object that not only motivated people to clean, but rather, one that went a level deeper and tried to deal with the social aspect, or lack thereof, in this particular kitchen dynamic Prototyping & Working • The initial solid model was prepared on SolidWorks and full-scale foam-core model was prepared • Once the fitment of all components (Arduino, Speaker and breadboard) was ensures, I made a final model cutting colored Acrylic sheets on laser- cutter and assembling them using tab joints & glue. • A housemate could record a message and when next housemate picks up Sponge to wash dishes, it automatically plays recorded messages (using Photo-diode) which transforms passive aggression into motivation.
  21. 21. SMOKESCOPE 5 Cent Smoke Detector INSPIRATION Over 3,000,000,000 people use three stone fire for cooking food which kills about 4 million people every year due to black smoke produced by it LNBL has developed an efficient cookstove but needs a low-cost device which could measure the adoption of the new cookstove Image Source: http://www.jced.net/projects/cook-stoves/
  22. 22. SMOKESCOPE 5 Cent Smoke Detector Prototypes • Based on user research we wanted to generate empathy and design a product that fits in their environment. • Team narrowed down on two ideas: • A toy which absorbs smoke • A camera device to take picture of exposed walls Prototype and B-Model • Conducted multiple user interviews and brainstorming session and developed a SmokeScope, a camera phone which would take pictures of exposed kitchen walls and compare to base white color • The housing will fit I-phone, will be made out of ABS and will provide a controlled environment to obtain similar image every time product is used • The fictitious company would leverage the already existing Carbon credit market
