Design Projects

Air Guitar Gloves

Design features a push-button on each finger to represent 4 strings (E, A, D, G); two buttons pressed represent a chord

String potentiometer fabricated to provide accurate distance measurements i.e. location on the fretboard

Skills Used: SolidWorks LabVIEW Machining

ME102B – Mechatronics/ME135 Design of Microprocessor-Based Mechanical Systems Spring 2012 with Professor Kazerooni/Professor Anwar

Winner of Departments

Mechanical Engineer for best Senior Design

Project

The Goal: To build a pair of gloves that allows the wearer to play guitar music using hand motions.

The team (from left): Aaron Krive, Leonard Carrier, Darshan Kasar, Chris Anderson, Me, Eric Bourgain-Chang

LabVIEW graphical user interface displaying string and fret locations as well as the key and distortion level

The ‘Amp’ houses the SB-RIO used for all data acquisition and allowed for easier organization of all the wires

ME 110 -New Product Development Spring 2012, Professor Yousseffi

Final prototype of our design. The lime green microfiber cloth is removable so that it can be washed and reused.

Gearing mechanism as-built.

Final 3D Model of our design produced and rendered in SolidWorks.

3D model close-up of gearing mechanism which allows user to push into the board while pushing the eraser to allow the user to exert force throughout the whole width of the board.

Sine Wave Generation

Mechanism The Goal: To design a mechanism that

draws sine waves with variable frequencies and amplitudes

Skills Used: SolidWorks Machining

A sample sine-wave produced by the mechanism.

Built prototype of mechanical sine wave generator.

ME 130 –Design of Planar Machinery Spring 2012, Professor Yousseffi

Final design utilizing a scotch- yoke mechanism for the vertical motion and a friction roller to produce a constant horizontal motion. The displacement of the pen is now a perfect sine wave

1. Variable amplitude slots for the scotch-yoke mechanism 2. Friction roller with rubber bands to pull the paper

through 3. Paper fed in from this side 4. Motor controlled by PWM circuit to allow for a changing

roller speed producing a changing sine wave frequency

DFMA Checklist

The Goal: To create a user-friendly GUI to help the pilot/ manufacturing engineers perform design for manufacturing and assembly analysis on incoming projects in alpha and beta stage of development

Skills Used:

Python (with wxPython graphics package)

The original checklist which overwhelms the user with information)

New front panel of checklist, organized by DFMA category

10

LAM Research, Pilot Operations Summer 2012, Frank Alvarez

Each category has several DFMA questions that allow the engineer to report issues relating to the question

Reference information relating to the question can be found by clicking on the question

A summary of the issues reported can be found here along with the severity. A score can be given to each issue that was found from 10 (non-issue) – 1(major issue)

If any major category scores below an 80%, then manufacturing sends the assembly back to the design engineers for a reevaluation and improvements

Campanile Project (Berkeley Clock Tower)

The Goal: To design a beam having a the general relative dimensions of the Berkeley Clock Tower (Campanile) that can survive a cyclic (10x) load of 20 N with no more than 0.5 mm plastic deformation and achieve survival of this load with as little material as possible (design for a high spring constant to mass ratio).

Skills Used: SolidWorks LabVIEW

a) Front view b) Side view c) Top view 3D prototype. Design features I-Beam cross-section which is very efficient at carrying bending loads along midsection.

ME 102A –Introduction to Measurements Systems for Mechatronics Fall 2012, Professor Pisano

Voted as one of the top 5 designs in the class because of

it’s smart use of material

Chassis Design Project

The Goal: To design a car chassis that has the highest bending stiffness and twisting stiffness per mass.

Skills Used: SolidWorks LabVIEW

3-D model of car chassis designed in SolidWorks
