Definition: Reverse engineering is the process of discovering the technological principles of a device, object, or system through analysis of its structure, function, and operation. It often involves taking something (e.g., a mechanical device or electronic component - a toaster or smartphone) apart and analyzing its workings in detail to be used in maintenance.
Requirements: A successful Reverse Engineering entry must have the following:
Locate and acquire one or two electronic or other complex objects to take apart (can be as basic as a spray bottle or fidget spinner or a complex as an iPhone).
The product is a real world item whose operation is not already super well known.
Project scope is reasonable and allows for disassembly to adequate levels.
Project must include:
1). A tri-fold display board (see tri-fold example page), and/or Google or PowerPoint slides, highlighting the requirements listed below:
Name of machine to be reverse engineered, your name, grade and teacher name
Operation of assembled unit is explained
Disassemble one product, then mount and label all components (or photos of parts), adequately describing function of each part
Layout of parts vs. assembled unit is organized, clear and promotes understanding of location and purpose
Written description explaining operation and functionality of all components - can include illustrations and/or images
The project clearly shows sequence of operation or cause and effect within the product
(Optional) Research history of product/invention
2). Visual aids or hands on item(s) to promote understanding
Some questions to guide your thinking:
Does this appliance come apart into two or more pieces?
What might some of these parts do?
Would the appliance work without the part?
What holds the parts together?
Do some of the parts come apart into even smaller pieces?
What tools did you use to get the pieces apart?
