  4. Main TOC POE TOC 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.

  5. Main TOC POE TOC 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: Maximum Load Supported Weight of Bridge

  6. Main TOC POE TOC 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.

  7. Main TOC POE TOC Marble Sorter • Objective: To create a device that will accurately sort marbles by color into three separate bins • Constraints: • Must use only Fischertechnik parts for everything except the hopper and the bins. • Bins must be able to hold all the marbles and their weight • Must use ROBOPro for all programming

  8. Main TOC POE TOC Marble Sorter Design and Development • These are the top, front, and side views of the marble sorter:

  9. Main TOC POE TOC Marble Sorter ROBOPro Program Screenshot • This is an image of the program used on test day:

  10. Main TOC Introduction to Engineering Design (IED) Table of Contents • Course Description • Sketches (Isometric, Oblique, 2-Point Perspective) • Puzzle Cube • Chess Piece • Reverse Engineering • Final Project (Portable Soap Box)

  11. Main TOC IED 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.

  12. Main TOC IED TOC 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

  13. Main TOC IED TOC Sketches • Isometric: Placed on a grid of 30 and 60 degree angles to show a top-right corner view for a small object • Oblique: Placed on a grid of 45 and 90 degree angles to show a non-distorted view of the front face while stretching the top and right views • Perspective: Drawn with respect to a base point and one or two vanishing points to show the real perspective that the viewer would have of a large object such as a building

  14. Main TOC IED TOC Puzzle Cube • Cube made of multiple pieces, with the following constraints: • Final dimensions 2.25X2.25X2.25 in. • Separated into 5 or more unique pieces • Dimensions of pieces can only be .75 in., 1.5 in. or 2.25 in. • Majority of the pieces must have three dimensions • Made in procedure, including: • Sketches • 3D Computer Aided Design • Orthographics • Assembly Drawing • Assembly Animation

  15. Main TOC IED TOC Puzzle Cube Orthographics • Orthographics are made for the purpose of conveying ideas to others for the purpose of production.

  16. Main TOC IED TOC Puzzle Cube Assembly with Parts List • Assemblies are a way of presenting an entire product with all parts separated and labeled, including the amounts of parts.

  17. Main TOC IED TOC Puzzle Cube Animation • Animations are used to show the function of an object before it is constructed

  18. Main TOC IED TOC Chess Piece • Group Project: Construct a set of chess pieces, with the following constraints: • Universal base, maximum dimensions 1” X 1” X .25” • All pieces with a common theme • Pawn with maximum height of 1” • Rook with maximum height of 1.25” • Knight and Bishop with maximum height of 1.5” • Queen with maximum height of 1.75” • King with maximum height of 2” • Construct a chess board to hold the pieces • All pieces must be parametric • Procedure includes: • Design Ideas with Sketches • 3D Computer Aided Design • Orthographics

  19. Main TOC IED TOC Chess Piece Sketches • I brainstormed ideas with my group for possible themes and sketched them. • Ideas narrowed to cubes, spheres, or words • Theme of “words” chosen with weighted decision matrix

  20. Main TOC IED TOC Chess Piece Orthographics • I made an orthographic drawing of my piece, the Rook. • This demonstrates the Note function and datum dimensioning, as well as symmetric dimensioning.

  21. Main TOC IED TOC 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.

  22. Main TOC IED TOC Reverse Engineering Orthographics • Parts were made using sweeps and lofts. The piece was then orthographically represented for the purpose of reproduction.

  23. Main TOC IED TOC Reverse Engineering Animations • I made an explosion and animation of the pliers. The animation shows all moving parts moving through almost the full range of motion. • Reverse Engineering Assembly

  24. Main TOC IED TOC 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.

  25. Main TOC IED TOC Portable Soap Box Sketches After creating a problem statement, I sketched ideas for the product to solve the problem of soap becoming wet while showering.

  26. Main TOC IED TOC Portable Soap Box Orthographics • To make the design more specific, the sketches were converted using Computer Aided Design into orthographic format.

  27. Main TOC IED TOC Final Project Assembly with Parts List • The project was then made into an assembly, and the assembly was orthographically represented with its parts list. This is another project.

  28. Main TOC IED TOC Portable Soap Box (cont.) • This is the movie animation of the soap box working (using Inventor parts). (All parts move without collision, including the soap itself.) (The box should have springs behind the button and two suction cups on the back, but that could not be made on Inventor.)

  29. Main TOC Digital Electronics (DE) Table of Contents • Course Description • Date of Birth Project • Fireplace Circuit Project • Majority Vote Project

  30. Main TOC DE TOC DE Course Description • Digital electronics is the foundation of all modern electronic devices such as mobile phones, MP3 players, laptop computers, digital cameras and high-definition televisions. Students are introduced to the process of combinational and sequential logic design, engineering standards and technical documentation.

  31. Main TOC DE TOC Fireplace Circuit Project • I made a circuit to operate a fireplace given various inputs. For this, I • Generated a truth table • K-mapped the logic • Simplified logic for two equations • Simulated two circuits using Multisim software • Built two circuits • Constraints: • One circuit used only two-input NAND gates • One circuit used only two-input NOR gates

  32. Main TOC DE TOC Fireplace Circuit Continued • Before breadboarding the project, I used Multisim to produce a simulation of the breadboard to avoid errors.

  33. Main TOC DE TOC Date of Birth Project • I created a circuit for a seven-segment display with the following constraints: • 3 switches • Use switches to simulate a time clock • Display my date of birth in MM-DD-YY format • One circuit is NAND only • One circuit is NOR only • All other circuits are AOI only • Solder Breadboard Companion for switches

  34. Main TOC DE TOC Date of Birth Continued • To avoid mistakes and ensure the circuit would work correctly, I first simulated the circuit with Multisim software. I also used it to construct some of the simulated circuitry more easily.

  35. Main TOC DE TOC Majority Vote Project • A circuit had to be designed to display pass/fail status of a four-vote system, with one overriding vote in the case of a tie. • The project was solved using: • Unsimplified logic • Logic simplification • Construction of the simplified circuit

  36. Main TOC DE TOC Majority Vote Continued • After creating the simplified logic, I built the breadboard circuit that would turn on a light to indicate a passing vote.

  37. Main TOC Engineering Design and Development (EDD) Table of Contents • Course Description • Evidence of Project Management Skills Applied • Gantt Charts • Decision Matrices • Initial Sketches • Final Idea • Final Powerpoint

  38. Main TOC EDD TOC 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.

  39. Main TOC EDD 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.

  40. Main TOC EDD TOC 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.

  41. Main TOC EDD TOC 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.

  42. Main TOC EDD TOC Initial Sketches • Initial ideas were created and then decided on by the weighted and unweighted matrices, based on how well they pertained to the design criteria.

  43. Main TOC EDD TOC Final Idea • Our final idea, to solve the problem of the bottom edges of walls becoming dirty, was a device with a flexible shaft and flexible head.

  44. Main TOC EDD TOC Final PowerPoint • To present our project, my group and I created a PowerPoint that summarized our entire project: • Final Presentation
