Holiday Ornament or Key Chain
Design Challenge
Target Outcomes:
  • Why are engineering drawings important?
  • Demonstrate how to draw an orthographic and isometric sketch using 3D solid modeling software.
  • How do we use scale when creating engineering drawings?

Vocabulary:
  • Scale
  • Orthographic
  • Isometric
  • Geometric Planes

Design Brief

Design Challenge:
  • Design and Create a holiday ornament, key chain, or bag tag using AutoDesk Inventor.  
Criteria:  
  • Your object should be no larger than 3 inches by 3 inches.  
  • You should have 1-2 pieces to your design (see the pictures above).  
  • You must have at least one thing that will be engraved into the design.  ​​

ENGINEERING DESIGN PROCESS

Procedure:
Throughout the entire project, students will document the Design Process of the project in their Engineering Notebook, recognizing where they are in the design process and using this step by step method to help them develop a product (Ornament & Key Chain). 
Step 1: 
Define the Problem
Picture
Eng. Notebook Example
identify a problem to be solved, its criteria, and its constraints. You will follow along with the teacher, as she Defines the Problem
Document in your Engineering Notebook:
 1.  In your own words, describe the problem/challenge that was given to you.
 2. List the criteria (details of what needed to be done) and constraints (limitations and rules) that were given to you.​​
Step 2: 
Generate Concepts
Picture
Eng. Notebook Example
Begin researching and brainstorming possible solutions for your holiday ornament or Key chain. 
Document in your Engineering Notebook:
      1. ​Research 
  • Collect  4 images. Place the four images on a one page Word Doc.​
  • Print out pictures
  • Cut pictures out and attach images to your Engineering Notebook. Next to each image Label and answer the following questions (Click on the image to the left to see an example of the layout in your notebook).
                  - What do you like about the idea?
                  - What would you change about the idea?
     2. Brainstorm and Sketch - This step is the key to a good design. Creating a large quantity of designs. provides a better chance at creating something spectacular. By doing this, it will provide a large pool of options to pull from. 
  • Brainstorm and create 2+ Thumbnail Sketches that are different from each other. These sketches should be small and rapid sketches. No bigger then 3" in size when sketching

CHECK OFF NOTEBOOK WITH MRS.SILVA WHEN FINISHED WITH STEP

Step 3: 
Develop a Solution
Select the best design: Determine which design is the best or combine multiple designs into one great design.
Direction:
     1. Watch the video to the left to show you how to import an image into Inventor and outline.
     2. Search google for an image you would like to use to trace for your outside shape of you ornament/key chain.
     3. Import image into Inventor and start outlining your image. Make sure to follow the steps in the video to set up your image correctly.  
​
Step 4: 
Construct a Prototype
Step 5: 
Evaluate the Solution
Student Self-Assessment & Reflection 
Document in your Engineering Notebook:
  1. Give a brief Description of the project you have completed.
  2. What did you like about this project? What were you able to do well?
  3. What did you NOT LIKE about the project? What problems did you have? Why?
  4. What did you learn about yourself? Strengths, interests, preferences, and needs.
  5. Was it easy or difficult following the Engineering Design Process (EDP)? Why?
  6. What might your do differently (better) if given the task again?
Step 6: 
 Present the Solution
