Virtual Product Dissection Educational Module
= Objectives =
The objective of this lab is to evaluate the functional design of a product and apply the discovered characteristics of that product to a new design. Product dissection is a type of reverse engineering that reveals how products work and can be used as a tool for design inspiration. The goal is to design an innovative water toy for use by kids aged 4-6. The toy must be safe and fun
to use.


This product dissection module was developed to introduce students to the use of product dissection as a means to inspire creativity in engineering design and provide a framework for application in their own design projects. The materials presented here are based on empirical studies on how to use product dissection as a tool for learning about how products work and as a tool for design inspiration. The material is presented through a variety of hands-on activities. See the timeline below for an overview of the time required for each of the activities.
= Overview =
Product dissection is often done in industry and academia to uncover opportunities for re-design. Designers take apart and analyze all components of a product to understand its structure and properties. Through understanding the product, design opportunities can be uncovered and applied to the redesign of a product. Therefore, the goal of dissection is to improve the functionality, maintainability, and reliability of a product through the examination, study, capture, and modification of other existing products. <ref name="one">Starkey, E., Hunter, S., & Miller, S.Learning with Product Dissection. https://www.engr.psu.edu/productdissection/.

== Reverse Engineering ==
== Engineering Design Process ==
Reverse engineering software involves reversing a program's machine code to obtain the original source code or determine the file structures the program uses. This is done when source code is lost or is not available. For example, when a project is reactivated after being dormant for years to add new features to a product, the original design documentation may have been lost. Also, when companies are writing a program that must interface with a second company's software, the second company may not have any incentive to cooperate by describing how the data in the files they use are organized, forcing the first company to deduce it on their own. Sometimes, this process is used to improve the performance of a program, to fix a bug, or to find a virus. When the source code is obtained in this way for any of these reasons, it is legal and necessary. Reverse engineering software  to copy it constitutes a copy¬right violation and is illegal.<ref name="two">''What Is ''website. TechTarget Network. Retrieved July 29th, 2003.</ref>
TThe engineering design process is used to systematically collect and analyze data on a product’s inner workings and make decisions to improve it or create a new product or service. There are a number of published engineering design processes, but the majority of them contain the same elements. As seen in Figure 1, the steps of the engineering design process include identifying the needs and assumptions, researching the problem, brainstorming, selecting a solution, prototyping, testing, and improving

Product dissection is an important tool to inform decisions in the researching, imagining, and planning stages. In particular, the “imagination” step, also referred to as brainstorming or ideation, can benefit from taking the concepts of an alternative product and applying it to a new design. In this lab, it is essential to ask about and identify the needs and constraints of the design. Future labs will cover prototyping, testing, and redesigning.


Hardware reverse engineering involves taking apart a device to see how it works. If a processor manufacturer wants to see how a competitor's processor works, the company can purchase the processor, disassemble it, and then make a new processor similar to it. In some countries, this process is illegal. Hardware reverse engineering is quite expensive and requires an expert in the field.<ref name="two"></ref>
== Design Fixation ==
Design fixation is a problem that engineers and computer scientists experience when they have preconceived notions of or create an initial idea for a design and cannot conceive alternatives. Some methods to overcome design fixation include product dissection, [https://www.designheuristics.com design heuristics], [https://www.mindtools.com/pages/article/newCT_02.htm SCAMPER], and brainstorming. Brainstorming is the idea generation that occurs during the conceptualization phase of the design process. Design heuristics and SCAMPER are methods that use modifying verbs to inspire alternative solutions. Product dissection uses the design characteristics of existing products and applies them in a new context.

== Reverse Engineering ==
The objective of this lab is to design and build a small vessel that floats on water. This is a competition lab that will be judged based on a ratio that uses cost and payload. In theory, the design should maximize the non-structural weight (payload) that the boat can lift and the time it can spend afloat, while minimizing the boat's structural weight and its cost. In practice, other design choices could also win the competition. Consider the components of the ratio and the rules before designing the boat.
Reverse engineering is the process of reproducing a product's specifications by the examination of the product's components and functionality. Hardware reverse engineering involves product dissection to see how a product works. For instance, if a processor manufacturer wants to see how a competitor's processor works, the company can purchase the processor, disassemble it, and then make a new processor similar to it. <ref name="three"></ref>

Software can also be reverse engineered. Reverse engineering software typically involves taking a program’s machine code (the compiled code) and converting it into a more human readable format. It can also be used to obtain the original source code or determine the file structures the program uses, when the source code is lost or unavailable. For example, when a project is reactivated, after being dormant for years, with the aim of adding new features to a product, the original design documentation may have been lost. The aim is to understand how a program functions in order to identify deeper issues, and thus find ways of fixing them.

Boats are lighter-than-water vessels. They are widely used for recreation, military, touring, and commercial purposes. Boats range widely in size, shape, material, and design, ranging in size from a single person kayak to a shipping boat that can hold up to 25000 tons of cargo. Your goal is to design and optimize a boat to hold as much cargo as possible while still making the boat as lightweight as possible.

=== Principle of Archimedes and Newton's Second Law of Motion ===
The Principle of Archimedes states that when a body is immersed in a fluid (a liquid or a gas), an upward force is exerted on the body that is equal to the weight of the fluid the body displaces. This upward force is called buoyancy.


A boat will float if the weight of the water being displaced is equal to or greater than the weight of the boat.
== Part 1: Creativity (10 minutes) ==
Creativity is an important part of the engineering design process as it is important to brainstorm in a creative mindset. A piece of paper and a pencil, or note app on a device of choice should be used to complete the paper clip ideation activity.
Paper Clip Ideation
* Take out a piece of paper and a pencil, or a note app on a device of choice
* Write down as many ways to use a paperclip as possible (2 minutes)
* After the timer has gone off, count up the number of ideas generated as a group
* Identify the greatest number of ideas generated and share
* Share any ideas that were not mentioned, including new ideas after others have shared


The Principle of Archimedes can be expressed in an equation, which is more useful for engineering calculations.
== Part 2: First Idea Generation Session (10 minutes) ==
List all ideas for the water toy down on paper. These ideas will be used to build upon after the dissection activity. This brainstorming session is performed individually and should follow the rules of brainstorming:


From the definition of density (''&rho; ='' mass / volume ''= m / V''), Newton's Second Law of Motion (''F = ma''), and for the acceleration due to gravity (''a = g''), the gravitational force on a volume of fluid is ''F = m*a = (&rho;V)(g)''. You can also calculate force using the definition of pressure, where pressure equals force divided by area (''P=F/A''), therefore force equals pressure times area (''F=P*A''). From here, pressure can be defined as hydrostatic pressure, which is equal to the gravitational force of acceleration (g) multiplied by the height (h) and density (''&rho;''). There are a few ways that the buoyant force can be calculated; these equations can help you think of ways to optimize the design of your boat:
* No (self) judgement
* Encourage wild ideas
* Stay focused on the topic

== Product Dissection Overview (5 minutes) ==
Product dissection is an idea generation method. Product dissection is often done in industry and academia to uncover opportunities for re-design and inspire new design ideas. The virtual products will be taken apart and analyzed to understand all components, its structure, and properties. This analysis will be used to find ways to improve the water toy ideas and/or be inspired for new design ideas. The goal is to improve the functionality, maintainability, and reliability of a product through the examination, study, capture, and modification of existing products. It can also inspire new design ideas by drawing inspiration from products in different design domains. It is ideal to dissect products outside of the area of design. For example, if the task is to design a new electric toothbrush, then it is best to dissect any product that is not a toothbrush. Watch the short tutorial video for [https://www.youtube.com/watch?v=mANf4dnBCno&feature=youtu.be SolidWorks eDrawings] for instruction on how to use product dissection tools in the software.

Objectives

The objective of this lab is to evaluate the functional design of a product and apply the discovered characteristics of that product to a new design. Product dissection is a type of reverse engineering that reveals how products work and can be used as a tool for design inspiration. The goal is to design an innovative water toy for use by kids aged 4-6. The toy must be safe and fun to use.

Overview

Product dissection is often done in industry and academia to uncover opportunities for re-design. Designers take apart and analyze all components of a product to understand its structure and properties. Through understanding the product, design opportunities can be uncovered and applied to the redesign of a product. Therefore, the goal of dissection is to improve the functionality, maintainability, and reliability of a product through the examination, study, capture, and modification of other existing products. [1]

Engineering Design Process

TThe engineering design process is used to systematically collect and analyze data on a product’s inner workings and make decisions to improve it or create a new product or service. There are a number of published engineering design processes, but the majority of them contain the same elements. As seen in Figure 1, the steps of the engineering design process include identifying the needs and assumptions, researching the problem, brainstorming, selecting a solution, prototyping, testing, and improving

Figure 1: Engineering Design Process.[2]

Product dissection is an important tool to inform decisions in the researching, imagining, and planning stages. In particular, the “imagination” step, also referred to as brainstorming or ideation, can benefit from taking the concepts of an alternative product and applying it to a new design. In this lab, it is essential to ask about and identify the needs and constraints of the design. Future labs will cover prototyping, testing, and redesigning.

Design Fixation

Design fixation is a problem that engineers and computer scientists experience when they have preconceived notions of or create an initial idea for a design and cannot conceive alternatives. Some methods to overcome design fixation include product dissection, design heuristics, SCAMPER, and brainstorming. Brainstorming is the idea generation that occurs during the conceptualization phase of the design process. Design heuristics and SCAMPER are methods that use modifying verbs to inspire alternative solutions. Product dissection uses the design characteristics of existing products and applies them in a new context.

Reverse Engineering

Reverse engineering is the process of reproducing a product's specifications by the examination of the product's components and functionality. Hardware reverse engineering involves product dissection to see how a product works. For instance, if a processor manufacturer wants to see how a competitor's processor works, the company can purchase the processor, disassemble it, and then make a new processor similar to it. [3]

Software can also be reverse engineered. Reverse engineering software typically involves taking a program’s machine code (the compiled code) and converting it into a more human readable format. It can also be used to obtain the original source code or determine the file structures the program uses, when the source code is lost or unavailable. For example, when a project is reactivated, after being dormant for years, with the aim of adding new features to a product, the original design documentation may have been lost. The aim is to understand how a program functions in order to identify deeper issues, and thus find ways of fixing them. Reverse engineering software to copy it constitutes a copyright violation and is illegal.[3]

Design Considerations

  • Design an innovative water toy for use by kids aged 4-6 (the toy will only be hypothetically designed).
  • The toy must be safe to use and fun.
  • Incorporate the dissected product's design functional characteristics below where applicable:
    • Power supply/energy source
    • Primary motion (how does it move?)
    • Energy flow
    • Form and outer body

Product Dissection Overview (5 minutes)

Product dissection is an idea generation method. Product dissection is often done in industry and academia to uncover opportunities for re-design and inspire new design ideas. The virtual products will be taken apart and analyzed to understand all components, its structure, and properties. This analysis will be used to find ways to improve the water toy ideas and/or be inspired for new design ideas. The goal is to improve the functionality, maintainability, and reliability of a product through the examination, study, capture, and modification of existing products. It can also inspire new design ideas by drawing inspiration from products in different design domains. It is ideal to dissect products outside of the area of design. For example, if the task is to design a new electric toothbrush, then it is best to dissect any product that is not a toothbrush. Watch the short tutorial video for SolidWorks eDrawings for instruction on how to use product dissection tools in the software.

Part 3: Product Dissection Activity (20 minutes)

Each team member should choose which product to dissect. A virtual product dissection handout is provided for documentation. Deciding which product to dissect should be done in project groups, and each member should dissect something different from their teammates. The available product models can be found below by clicking on the image or link to download. After the products have been chosen, the tutorial video for SolidWorks eDrawings can be viewed to review the product dissection process and how to use the software.
