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

Eng. Notebook Example

In this first step, we will 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

Eng. Notebook Example

In this second step, you will begin researching and brainstorming possible solutions for your holiday ornament or Key chain. 
Document in your Engineering Notebook:
      1. ​Research and Collect  6+ images (Save the images to your flash drive). ​
     2. Bring your flash drive to Mrs. Silva to print out images.
     3. Cut 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?
     4. Brainstorm and Sketch - This step is a key to good design. Creating a large quantity of designs             (10-15+) provides a better chance at creating something spectacular. This provides a large pool of           options to pull from. However, I would like for you to only Brainstorm and Sketch 4+ different       
         potential ideas. Sketches should be small and rapid sketched.

Step 3: 
Develop a Solution

Autodesk Inventor Sketching Practice Assignment

Select the best design: Determine which design is the best or combine multiple designs into one great design.
Document in your Engineering Notebook:
     1. First complete the practice assignment on how to use the sketching commands
        in Autodesk Inventor.
