POE Course Description

This survey course exposes students to major concepts they’ll encounter in a post-secondary engineering course of study. Topics include mechanisms, energy, statics, materials, and kinematics. They develop problem-solving skills and apply their knowledge of research and design to create solutions to various challenges, document their work and communicate solutions.

Bridge Building Project

Unit 4 of Principles of Engineering covered free body diagrams, vectors, and bridge trusses. My group was responsible for creating a bridge with a high efficiency rating, determined by the following formula:

Bridge Building Continued• Over all our bridge’s efficiency

was 371.23• The key to our design was our

sturdy supports above and below the deck. The only thing on our entire bridge that even cracked was one reinforced popsicle stick. Unfortunately, that one stick was in the very center of a side on our bridge.

Main TOC

IED Course Description

The major focus of IED is the design process and its application. Through hands-on projects, students apply engineering standards and document their work. Students use industry standard 3D modeling software to help them design solutions to solve proposed problems, document their work using an engineer’s notebook, and communicate solutions to peers and members of the professional community.

Sketches

Sketching is important because: Ideas are quickly and easily captured on paper Ideas can be placed in an engineer’s notebook Items can be described accurately and

visually with different perspectives

Sketches

Isometric:Placed on a grid of 30 and 60 degreeangles to show a top-right corner viewfor a small object

Oblique:Placed on a grid of 45 and 90 degreeangles to show a non-distorted viewof the front face while stretching thetop and right views

Reverse Engineering

A mechanical device was to be taken apart and recreated on 3D Computer Aided Design software. It was then to be improved upon in some way, such as form, material, or function.

Parts were made using sweeps and lofts. The piece was then orthographically represented for the purpose of reproduction.

Final Project (Portable Soap Box)

For the final project, I worked with a partner at my school and two partners at another school.

We completed a Gantt Chart and designed a portable soap box to be mass produced.

We made annotated sketches, Inventor parts, an assembly, and a Windows movie of an animated assembly and soap bar.

I made a prototype, and my partners made a PowerPoint presentation, which we then presented to our class.

After creating a problem statement, I sketched ideas for the product to solve the problem of soap becoming wet while showering.

To make the design more specific, the sketches were converted using Computer Aided Design into orthographic format.

The project was then made into an assembly, and the assembly was orthographically represented with its parts list. This is another project.

EDD Course Description

Students work in teams to design and develop an original solution to a valid open-ended technical problem by applying the engineering design process. Students perform research to choose, validate, and justify a technical problem. After carefully defining the problem, teams design, build, and test their solutions while working closely with industry professionals who provide mentoring opportunities. Finally, student teams present and defend their original solution to an outside panel.

Main TOC Evidence of Project

Management Skills Applied In order to effectively complete the project on

time, I had to use several project management tools to achieve goals.

I used Gantt charts to track progress and set goals.

I used weighted and unweighted decision matrices to make informed important decisions

I managed a budget I contacted vendors to purchase materials I contacted a mentor to have questions

answered.

Gantt Charts

Gantt charts were used throughout the year to check progress and set goals. They are useful because goals can be set both long-term and short-term in relevance to the length of the whole project.

Decision Matrices

Decision matrices can be used to make informed decisions important to the project in an easy-to-measure manner, such as a decision on a final design.
