IED Unit 10: Design Challenge

Solving Real World Problems with the Engineering Process

PLTW DESIGN CHALLENGE

 Download the Bug Bot Assignment

This unit will give us a chance to apply the engineering design process and the various modeling skills we’ve developed to create a solution to a real-world problem.  In addition, we’ll look at the lifecycle of the products we design and the ethical implications of engineering work. In the end, we’ll organize our work by following the engineering design process:

  • Define the Problem & Create a Design Brief
  • Research & Brainstorm
  • Pick a Solution
  • Build or model a Prototype
  • Test & Evaluate
  • Communicate Results

In doing this, not only will you and your team be able to develop the solution to a real-world problem, we’ll also be able to submit your work to the national Project Lead The Way engineering design competition.

  1. STEP 1: Take some time to review the principles of design ethics and the product life cycle, taking some careful notes in your engineering notebook.
  2. STEP 2: Work with your group to develop a design brief, research, and brainstorm possible solutions.  Your chosen solution will then be fully described and prepared for development.
  3. STEP 3: Work with your group to pick a solution, and write-up how the solution will work. Continue to cooperate to sketch your solutions and create a model in Autodesk that might include multiple parts and an assembly

When you’re done, you’ll have gotten to practice the engineering design process again and will have created a submission for a national PLTW Engineering Design Competition.

PART 1: LIFECYCLE & ETHICS

(20 pts) About 2 days

Engineers have to consider how their products, production processes, and decisions impact the environment and society.  In this first part of the unit we’ll look at the lifecycle of a product from the beginning of its production through the end of its useful life and beyond.  We’ll consider design ethics and what factors need to be considered when developing a new idea.

PART 2: DESIGN BRIEF, BRAINSTORM & SOLUTION

(50 pts) About 4 days

Here you’ll work with your team to work through the engineering process.  You’ll identify a real-world community problem; research, brainstorm, and select your solution; and fully describe your solution through proper documentation, short essays, and photos.  The steps of the engineering design process will create your submission for the PLTW Design Competition.

PART 3: DESIGN & COMMUNICATE

(50 pts) About 4 days

Finally, your jobs will be to 3D model your solution in Autodesk.  You and your team should make a careful model and assembly that demonstrates how it will solve the problem.  You’ll then need to work together to upload your design solution, process, and written submissions to the national PLTW Design Competition.

Part 1: Lifecycle & Ethics

Consider the production process and the role engineers play in modeling good ethics

Product Lifecycle Overview

As engineers develop solutions to problems, they need to be careful about not creating new problems along the way!  To do this, it’s important to consider the lifecycle of a product and the ethics that play into the engineering process.  First, watch the “Product Lifecycle” presentation, taking some notes in your engineering notebook.  Then, with those in mind, watch the three (3) “How It’s Made” videos and respond briefly to the questions at the end of each one.  Finally, review the Design Ethics presentation, taking further notes about how this impacts the engineering design process.

GRADING & PROCESS

Watch the Product Lifecycle presentation and take careful notes on the big ideas.

Watch the three How It’s Made videos and answer the response questions at the end of the video in your engineering notebook.

 Review the Design Ethics presentation, and finish your page of notes by with ideas from this presentation

 Have Mr. Benshoof approve your notes

Ethics in Engineering

How It’s Made: Magnets

Design Ethics

How It’s Made: Recycling Batteries

What’s Due In Part 1: Lifecycle & Ethics

  • Product Lifecycle
  • How It’s Made
  • Design Ethics
  • Mr. Benshoof’s Confirmation

Here’s what’s due in Part 1: Lifecycle & Ethics

  1. Notes on the product lifecycle in your engineering notebook
  2. Watch How It’s Made video and respond to questions in notebook
  3. Notes on the Design Ethics presentation in your engineering notebook
  4. Have Mr. Benshoof confirm your notes

Part 2: Design Brief, Brainstorm & Solution

Work through the engineering design process to solve a problem

Problem & Brainstorm Overview

 

This next part of the unit will have you work with your team to define a local problem and then research, brainstorm, and select a solution.  We’re very used to the engineering design process, and this is a chance to use it to solve one more problem!  Your team needs to select a real-world community problem that can be solved with the tools we have readily available here in the lab. After creating a complete design brief, your team will research and brainstorm lots of ideas before using a decision matrix to select your final solution!

GRADING & PROCESS

 Work with your team to identify a real-world problem and develop a design brief – have everyone record the design brief in their own engineering notebook.

 Research and brainstorm at least 20 possible solutions to your problem and record them.

 Use a decision matrix to decide between the best ideas and agree with your team on your final solution.

 Describe your solution with a mix of concept sketches and written descriptions in your notebook.

 Have Mr. Benshoof check-off your design brief and solution!

What’s Due In Part 2: Design Brief, Brainstorm & Solution

  • Design Brief
  • Research & Brainstorm
  • Decision Matrix
  • Solution Description
  • Benshoof’s Check-off

Here’s what’s due in Part 2: Design Brief, Brainstorm & Solution

  1. A design brief that fully explains the problem your team has chosen to address
  2.  A list of at least 20 ideas from your team’s research and brainstorming
  3. A decision matrix that helps select your final idea from your best 5 ideas
  4. A concept sketch and written description of your team’s chosen solution
  5.  Benshoof’s check-off of your design brief and solution

Part 3: Design & Communicate

Submit your idea to the PLTW Design Challenge

PLTW Design Challenge Submission

The final step to any engineering project is to share your work with others.  This can be done using written documentation, drawings and diagrams, 3D models, written responses and essays, pictures, or video.  For the National PLTW Design Challenge, you and your team will create an online portfolio of your design work.  This portfolio can include as many elements as your team wants, but must be complete and submitted by the competition deadline!

GRADING & PROCESS

 Agree with your team on your final solution

 Discuss the product lifecycle of your solution and make notes in your notebook outlining the product lifecycle and how it impacts society and the environment

 Make a 3D model of your solution in Autodesk – if appropriate, make an assembly that shows how pieces interact

 Complete the online PLTW Design Challenge design process portfolio

 Submit your team’s work by the competition deadline

 Have Mr. Benshoof confirm your team’s submission!
