Senior Design II proposalA step-by-Step review

What is Senior Design?

Senior Design is a sequence of two courses during two consecutive semesters

The courses are named Senior Design I and Senior Design II. Electrical and Computer Engineering Students are supposed to take them during their last two semesters as Engineering Students ad FIU

Senior Design I is a 2 credit, lecture type course while Senior Design I is a 2 credit Directed Individual Study

The activities the students perform during this combination of courses would be the equivalent in the industry of a complete Project Life Cycle

What is Senior Design?

The Senior Design sequence is mainly a project management experience which includes the design of a final product

The Electrical and Computer Engineering Students dedicate a considerable amount of time in this process and over time they have increased our expectation for the Senior Design II demonstrations as very intriguing projects continue to be presented

What is Senior Design?

During Senior Design I students:

• Form a multidiscipline team and practice to achieve effective communication skills

• Determine the project requirement and specifications• Do most of the research• Check for patents infringement• Do a preliminary Design keeping in mine the industry

standards• Estimate the Time Line and the budget

In this process students make sure that:

• The best ethical principles are used and• Health, safety and the environment are preserved

What is Senior Design?

During Senior Design II students:

• Perform the Detailed Design• Build a prototype• Test and Evaluate the prototype• Discuss with their mentor any changes in the

requirement or in the specificationsIn this process students make analyze:

• The results of the project• How the budget and the timeline changed• Elaborate a final conclusion on the project

What is The Senior Design II Proposal?

The Senior Design II Proposal would be our equivalent to the Preliminary Design Review (PDR)

All the activities during Senior Design I circle around the Senior Design II Proposal

In order to pass Senior Design I Students must have a proposal signed by The Mentor, The Senior Design I instructor and all the team members

What is The Senior Design II Proposal?

The main aspects of the Senior Design II proposal are:

• To determine the Problem Statement and Project Objectives

• To determine the Project Specifications• To conduct a Technology review that includes:

• Similar Projects• Patents• Standards

• To establish the management schedule of the project based on:

• Time lines and• Budget

What is The Senior Design II Proposal?

The main aspects of the Senior Design II proposal are (cont.):

• To set the health and safety goals• To make correct decisions base on:

• Preserving the environment• Improving Manufacturability• Assuring Sustainability

• To Determine the project feasibility and the risks involved

• To Analyze different concepts and select the one that fits best to the project

• To produce a preliminary design and communicate it effectively by means of text and diagrams

What do we make Different?

Our Students form a Team and find a Mentor Early in the process

Our Students do most of the research and the writing during Senior Design I

Our Students start the design very early in the process, even when the Senior Design II Proposal is not complete

PROBLEM STATEMENT

At this point students have found a topic and a mentor.

• To emulate real world situations where designers (The students) design for Clients based on user needs, the Mentor assumes the role of the Client and therefore the Mentor can establish his/her own Project Requirement

Students determine the Problem Statement, Objectives, Constraints and Limitation based on their interaction with:

• The Client by means of a structured interview• The potential Users by means of a Survey and• The other Team Members by means of Brainstorming

NEED ANALYSIS/The Client Interview

Prepare a Structured interview with questions like:

• When and why do you use this type of product?• Walk us through a typical session using the product.• What do you like about the existing products?• What do you dislike about the existing products?• What issues do you consider when purchasing the

product?• What improvements would you make to the product?• Are there already products on the market that have

similar features?• And you can always ask a second question:

• What does that mean?• Why do you want that?

The main goal of this project is to design and build a prototype of a safe screwdriver that will be useful for metal and wood works. The screwdriver will be good for indoor as well as outdoor jobs and will resist water and shocks. The unit must be safe, allow works on electrical equipment and pose a minimum risk of causing short circuits. Emphasis will be stressed on easiness of use, storage and durability. Users of the newly design screwdriver will feel a comfortable experience with minimum fatigue and will be able to work under the rain with no safety risks. The cost of the unit must not exceed $95 and it must be OSHA compliant.
