Example：（No copy, No paraphase,）I gave this example to telling you the format.

1. Functional Decomposition of a Personal Computer:

Perform a functional decomposition of a personal computer. First do a simple dissection of the product using the FAST technique; restrict this dissection to the major subsystems of the product. Then create a function structure (FS) for the product as follows. Start with a single block showing the overall function, inputs and outputs of the product. Then decompose this product into sub-functions, and draw the function structure (at least 3 levels deep) for the products. Clearly identify the material, energy, and information flows into and out of each subsystem or component. Describe the differences between the FAST diagram and Function Structure.

Define: Our goal for this problem is to perform a functional decomposition of a personal computer. To complete this we have to do a simple dissection of the product using the FAST technique, then create a function structure. To do this we start a single block showing the overall function, inputs and outputs of the product. Our next step is to decompose this product into sub-functions and draw the function structure. Lastly, we will describe the FAST diagram and Function Structure.

Plan:

1. Simple dissection of the product using the FAST technique

2. Create function structure for the product

a. Start with a single block

b. Decompose into sub-functions

c. Draw the function structure

3. Identify material, energy, and information flows into and out of each system or component.

4. Describe the differences between the FAST diagram and the Function Structure.

Execute:

1. Simple dissection of the product using the FAST technique

2. Create function structure for the product

a. Start with a single block

b. Decompose into sub-functions

c. Draw the function structure

3. Identify material, energy, and information flows into and out of each system or component.

4. Describe the differences between the FAST diagram and the Function Structure:

a. One difference between the FAST diagram and the Function Structure is that the FAST diagram refers to function and form - the Whys and Hows while the Function Structure focuses only on the functions.

b. FAST diagrams help break down existing products and Function Structures contain new sub functions that don’t already exist in related products.

Check: Using lectures, notes, and my knowledge of FAST diagrams and Function Structures, I was able to create both for a personal computer.

Learn/Draw Conclusions: This problem helped me further my ability in creating FAST diagrams and Function Structures. I was able to see the differences and see what goes into creating a personal computer.

2. Conceptual Design for an Indoor Mobile Robot

Design a mobile robot capable of moving indoors, climbing stairs, and performing useful tasks like cleaning. Proceed as follows: First, using a structured process, develop 4-6 alternative design concepts. Then, using an appropriate utility function, assess and compare these designs to select the “best” alternative for further development

Define: Our goal in the problem is to design a mobile robot capable of moving indoors, climbing stairs, and performing useful tasks like cleaning. We will be creating 4-6 alternative design concepts.

Plan:

1. Design robot

2. FAST diagram

3. Customer needs and technical specs

4. Function Structure

5. Alternative design concepts

6. Assess and Compare designs

Execute:

1. Design robot: The primary function of the mobile robot will be to move indoors, climb stairs and perform useful tasks such as cleaning.

2. FAST diagram

3. Customer needs and technical specs

4. Function Structure

5. Alternative design concepts

6. Assess and Compare designs:

Based on these designs, the best bet would be to get a vision sensor with a proximity detector to avoid obstacles, but know where steps are. Use legs to climb the stairs and a vacuum to clean.

Check: Based on what was gone over in class and lecture notes, these are the diagrams and concepts I believe work the best.

Learn/Draw Conclusions: This problem helped me create my own indoor cleaning robot and go through a step by step process of designing and creating a product.
