Course Syllabus Course overview and objectives: This is a design-driven course with emphasis placed on skills such as: team-working, communication skills (graphical, oral, and written), and computer-aided design and analysis tools. The course will introduce students to the engineering approach to problem solving with strong references to basic science and math skills, as well as testing and evaluating design ideas by building prototypes. The design projects are 2 the total of at least 30 hours of in-class work (one third of the course). Two design projects will be assigned during the semester. The design projects will require the students to work in a team. The course grade for the students will reflect their abilities to function effectively as team players. Class policies: 1. Assignments are due at the start of the class period before the lecture begins. Assignments submitted after this time will receive a 20% deduction. A further 20% reduction will be applied for every week beyond the first. 2. The instructor will discuss any exam or assignment grade within 48 hours (excluding weekends and holidays) of its return, after which time the discussion is closed. 3. Excellent teamwork can improve the course grade by as much as 4% (2% per design project). Poor team work will lower your grade by the same amount. 4. Punctual attendance is mandatory for all the class periods. Course grade will be dropped to the next lower grade for every two classes missed. All excused absences must be supported by written documentation, such as doctor's receipt, Penn State athletics travel notice, ROTC notice, etc. 5. No makeup labs will be available for the Design sessions since this is unique to this section. 6. No cell phone including text message is permitted in the classroom. 7. Students are responsible for any missed handout and homework assignment for any unexcused missed class. 8. Students must use Penn State access account email address when he/she emails the instructor. Academic Principles: Senate Policy 49-20 Academic Integrity Definition and expectations: Academic integrity is the pursuit of scholarly activity in an open, honest and responsible manner. Academic integrity is a basic guiding principle for all academic activity at The Pennsylvania State University, and all members of the University community are expected to act in accordance with this principle. Consistent with this expectation, the University's Code of Conduct states that all students should act with personal integrity, respect 6 other students' dignity, rights and property, and help create and maintain an environment in which all can succeed through the fruits of their efforts. Academic integrity includes a commitment not to engage in or tolerate acts of falsification, misrepresentation or deception. Such acts of dishonesty violate the fundamental ethical principles of the University community and compromise the worth of work completed by others. The Penn State Principles: 1. I will respect the dignity of all individuals within the Penn State community; 2. I will practice academic integrity; 2

3. I will demonstrate social and personal responsibility; 4. I will be responsible for my own academic progress and agree to comply with all University policies.

EDSGN 100 Introduction to Engineering Design Design Project #1: Folding Shopping Cart Design Task: Design and build a prototype of a folding shopping cart for people without cars, or people that need to carry groceries longer than from garage. Design Specifications: 1. 2. 3. 4. 5. 6. The folding shopping cart should be easy to use (and assemble, if required). The folding shopping cart should be ideal for transporting groceries and some other materials. The folding shopping cart should fold compactly for easy storage. The material cost for the folding shopping cart should not exceed 50 unless it can be justified. The folding shopping cart should have a weight capacity of 100 lbs. Key Deliverables: A design report to be published on the web with the following items included (Note: Guidelines for the lab report will be given later): 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. Problem statement Mission statement Customer needs assessment Gantt chart Design approach (concept generation and concept selection with design matrix) Working drawing Prototype (images, scale, operation instruction, etc.) Working mechanism and engineering analysis Cost analysis Conclusion References (if any) Acknowledgement (if any) Evaluation Criteria: Design meets specifications Creativity/Innovation Working mechanism and operation instruction are clear Ease of operation Safe to use Cost efficient 12

Main Design Features: There are several key features of this product that make it easy to use. First and foremost, is the locking mechanism on the back of the cart. This mechanism makes it so that the cart can fold up and stay folded when not in use, but when it is needed, the back will not flop forward when pushed. The next key feature is the material lining the sides. It is a fabric similar to those used in lawn chairs, which is flexible, yet sturdy. Moreover, it will allow the cart to fold on itself without breaking or having multiple moving parts. Finally, it the detachable spokes in the front of the cart, which can be removed and placed within the back when it folded allowing it to lay flat without any part protruding from it. 14

Main Design Features: Since there are so many dynamic and moving parts to the design, there are many key design features to consider. The first is how the machine operates, which is through a hand crank on the side. This is connected to a gear system, which through a chain, and various gear ratios, operates all of the moving parts in the machine. The first important part of the machine is the primary dough bowl, which mixes flour and water into the dough, and dispenses it onto a rolling track. The second part are two large rollers, which flatten the dough out. Once the dough is completely formed, it is gently folded into shape, while a funnel above dispenses the filling. Finally, two spinning presses fold the dumpling shut. 19

Conclusion and Summary While completing this class in a six-week span was no simple task, the help I received from Dr. Wu, the TA’s and my classmates helped me work though it and be successful. This course has given me a great insight into and foundation for a future in engineering. The practice assignments in SolidWorks and drawing were great starts towards more complex work, and the group projects taught us the value of working together towards a common goal. While mistakes were made, they only helped me learn and I was always willing to learn from them. This course and all I learned from it will be greatly useful to me in the future. Acknowledgements I would again like to thank Dr. Xinli Wu for his teachings and advice, as well as the TA’s Jerod Barone and Michael Gillett for their assistance throughout the class. 20
