Why do People Reverse Engineer Products?
STEMCenter for Teaching & Learning™ Engineering byDesign™ 12/01/2009 Why do People Reverse Engineer Products? The original manufacturer of a product no longer exists and/or no longer produces the product. The product has features that are negative and/or to improve the product’s performance and features.

Why do People Reverse Engineer Products?
STEMCenter for Teaching & Learning™ Engineering byDesign™ 12/01/2009 Why do People Reverse Engineer Products? To update obsolete materials or antiquated manufacturing processes with more current, less-expensive technologies. To gain a competitive advantage by understanding how a competitor’s product functions and/or is produced.

Steps of Reverse Engineering
STEMCenter for Teaching & Learning™ Engineering byDesign™ 12/01/2009 Steps of Reverse Engineering Prediction: Based on research and your knowledge of the product, make predictions about how the product functions and why it was designed. Sample questions: What is the purpose of this product and how does it function? Who is the intended audience?

Steps of Reverse Engineering
STEMCenter for Teaching & Learning™ Engineering byDesign™ 12/01/2009 Steps of Reverse Engineering Observation: Using the systems model, make observations about the various inputs, processes, outputs, and feedback that enable the product to function. Sample questions: What are the inputs/processes/outputs of the product? How does the product produce feedback?

Steps of Reverse Engineering
STEMCenter for Teaching & Learning™ Engineering byDesign™ 12/01/2009 Steps of Reverse Engineering Disassemble: Carefully dissect the product, noting all of the components. Sample questions: Can you develop annotated sketches that include measurements and notes on each of the various components? Can those parts be categorized?

11
Steps of Reverse Engineering
STEMCenter for Teaching & Learning™ Engineering byDesign™ 12/01/2009 Steps of Reverse Engineering Analyze Carefully document, examine and analyze each of the subsystems (i.e., structural, mechanical, and electrical) and determine how they interact. Sample questions: What are the various subsystems of the product and how do they interact? What are the parts of the system and various subsystems? [Authors: Please include teacher notes appropriately.] © 2013 International Technology and Engineering Educators Association, STEMCenter for Teaching and Learning™ Foundations of Technology © International Technology Education Assoc
12
Steps of Reverse Engineering
STEMCenter for Teaching & Learning™ Engineering byDesign™ 12/01/2009 Steps of Reverse Engineering Test Carefully reassemble the entire product and/or one or more of the subsystems to determine how the product functions. Sample questions: How do the subsystems operate together? When the entire product is reassembled, does the device function? Record all observations.

Steps of Reverse Engineering
STEMCenter for Teaching & Learning™ Engineering byDesign™ 12/01/2009 Steps of Reverse Engineering Documentation Each step in the process of reverse engineering should be documented. Document all design goals, constraints, functionality, form (geometry), and materials Develop schematic diagrams that describe the components and materials Identify any refinements that might enhance the product’s usefulness [Authors: Please include teacher notes appropriately.] © 2013 International Technology and Engineering Educators Association, STEMCenter for Teaching and Learning™ Foundations of Technology © International Technology Education Assoc
