Creative Decisions and Design


Here are links of PPT PowerPoint Presentations, pdf PDF documents and word Word documents.

Topics

To learn the fundamental procedures for solving engineering design problems; the essential details of analyzing, synthesizing, and implementing design solutions with flexibility, adaptability, and creativity; the techniques which allow an engineer to tackle new, unsolved, open-ended problems. Implement fundamental design discpline and effectively execute the design process for design project assignments.

1. Studio 1 Introduction to Design Quality Studio: Is a mechanical dissection of various electric toothbrushes conducted in a group of two. The physical dissection and investigation are to be performed in studio while the report will be written outside of the studio. The task involves the following: dissection of an Oral-B CrossAction Power electric toothbrush with replaceable battery; inspection of an Oral-B CrossAction Power electric toothbrush with rechargeable battery; and inspection of two Crest SpinBrush PRO-CLEAN electric toothbrushes with replaceable batteries (one will be pre-dissected). The task is to inspect them, sketch them, determine how they operate, and reassemble them so they work.

2. Studio 2 Machining and Mechatronics Project: In the Squash Superbowl Half-Time Show Project students learn how to program a controller box, as well as use sensors and actuators. In addition students learn how to use machine tools in the lab.

3. Studio 3 Introductory Design Project: The objective is to propose a design for a Sustanable Water Heater. This involves the use a design objectives tree, problem understanding form, house of quality, design specifications sheet, alternative concepts, and concept evaluation.

4. Studio 4 Tech Startup: The goal of the this studio is to design, build, prototype and finalize an autonomous robotic system, or machine, to compete in the ME2110 Tech Startup design competition by completing a series of tasks that emulate the creation and launch of a technology startup.

Studio 4 Tech Startup

Ballistic Panda

The team was composed of John Compton, Sebastian Li, Aida Yoguely Cortés-Peña, and Phuc Le.

The objective of this project is to design, build, and finalize an autonomous robotic system that can compete in the ME2110 Tech Startup design competition and that will earn the maximum amount of money points, $95, by completing all the series of tasks.  The selected strategy for winning will be the completion of assigned tasks in the following priority order: fit in box, raise capital gate, win the government contract, secure patent rights, invest startup funds, and finally to launch products to market. The design requirements of the machine is to be autonomous, fit inside a 24”x12”x18” box, launched within the starting zone, be safe, and use only the actuators given for the project.  The project has many challenges which includes building the robot within a 7-week period, being less than $100 in budget, and adhering to tolerances across the competition arena. The Team name is Ballistic Panda and it is numbered E2. In studio competition resulted in 4th place. The functional goal emphasized was to create a robust machine that would have the highest repeatability in scoring points. The challenge addressed in accomplishing this goal was to design a simplistic, minimalist, machine with the least number of parts, sensors, and actuators. The solution developed consists of three subsystems that accomplish four tasks. Each subsystem triggers the next in a self-actuating manner. During the actuation of the first system to raise capital, a lever raises and allows a drawer slider to move freely and press the government contract button. The second actuator deploys the invest startup funds system which consists of a four bar parallelogram linkage, simultaneously triggering the sponge collectors to secure patent rights. This report presents the creative design process as well as the management and project planning carried out for the successful design and completion of the machine. The final design and its subsystems are described together with its evaluation from prototyping and competition results. The following management and planning tools were used: Affinity Diagram, Tree Diagram, Prioritization Matrix, Job Responsibility Matrix, and a Gantt Chart. The following design approach tools were used:  Objectives tree, problem understanding form, function tree, specification sheet, and quality function deployment. The following conceptual design tools were used to aid in the selection of the final system: Function Decomposition, Morphological Chart, and a 3rd Level Evaluation Matrix. Finally, the results from prototyping and competitions were analyzed for the continual improvement of the mechanical system, as well as the design process itself.

Spring 2013 ME 2110 Design Contest

I competed at the Spring 2013 ME 2110 Design Contest which took place on Friday, April 5 2013 at 5pm in the atrium of the MARC Building. The project theme for the semester was "Tech Startup." The student teams designed, prototyped and fielded autonomous machines, or startup robots, that emulated a small technology startup venture and competed to launch products to market, generate revenue, and stimulate growth.
