Day 5 DM

Design & Modeling Challenge

What types of careers were you introduced to in today's lesson? Identify ways at least one of the professionals can help a patient with cerebral palsy.

Over the next few weeks, you will learn to practice the skills you need to be ready for the toy design challenge.

Present Your AFO

Ankle Foot Orthosis (AFO)

Requirements

• How did you develop your idea?
• What struggles did you have?
• What changes did yo make to improve your design?
• Why do you think your design will satisfy the patient's needs?

Essential Learning

Today's Success Criteria

• The student will use the EDP to design a simple experiment with a control and variables.
• The student will use the EDP to construct a prototype that meets certain specifications.
• The student will describe, explain, and develop adaptive and assistive bioengineered products.
• The student will create a scaled model of a design concept.

• attaches to the patients' foot and lower leg
• allows upward movement at the ankle, where the foot or toes move in an upward direction towards the shin
• places the foot flat on the floor when standing
• prevents the patient from pointing or rising up onto their toes
• supports the foot and ankle, including the heel and arch of the foot
• comfortable to wear--pay special attention to areas where bones may stick out; too much or too little padding can create pressure points, which can create wounds
• removable

A Picture is Worth a Thousand Words

Before you begin your instant challenge, complete the following:

• Company jobs
• Company contract
• Individual design sketches
• Decision Matrix

Thumbnail Sketch

Create a thumbnail sketch on Cartesian (square) graph paper of a small object created from linking cubes. Remember to make the width and height of the object proportional in your sketch. Add some basic details and darkness to the lines before you share your thumbnail sketch.

• We communicate ideas every day by talking with friends, texting messages, or sharing videos.
• Engineers often communicate their design ideas visually.
• Sketches are a quick way to share ideas with others. Even if you think your drawing looks awful, a sketch can be worth a thousand words.

Isometric Sketch

An isometric sketch is drawn at a 30-degree angle from the horizontal base line, to show three sides simultaneously. Isometric graph paper and a ruler will help you draw straight lines at this angle. Create an isometric drawing of the object you created for the thumbnail sketch.

Using isometric graph paper, create an isometric sketch for a design of a cardboard box that has a rectangular hole cut into one side of the box.

Multiview Sketch

Create a multiview sketch of the object below. You can build the object with the linking cubes.

1. Use isometric graph paper to create an isometric

sketch of the object.

2. Cut out the isometric sketch and paste it onto

Cartesian (square) graph paper. Position the isometric sketch in the top-right corner of the graph paper.

3. On Cartesian (square) graph paper or in your Gateway

Notebook, practice drawing multiview sketches of the following objects presented as isometric sketches. You may want to build the objects with linking cubes to help you see the three primary views of each object.

Mystery Object

Using the multiview sketch in to the right, build the three-dimensional object with linking cubes. Think about each view and how a three-dimensional object would look given each side’s projection.

When you've finished constructing the three-dimensional object, draw the isometric sketch that’s missing in this multiview sketch on isometric graph paper.
