• Background Agenda • • Problem Statement • Customer Requirements • • Open Items from Last Review Engineering Requirements Systems Design • Concept Development • Engineering Analysis • Risk Assessment
Open Items From Last Review Refine Risk Assessment Develop modules on experimental and analytical levels
• Problem Statement & Deliverables Current State • • Desired State • • Three to four modules used to provide a set of advanced investigative scenarios that will be simulated by theoretical and/or computational methods. Project Goals • • • Students in the Mechanical Engineering department currently take a sequence of experimental courses, one of which is MECE – 301 Engineering Applications Lab. Create modules to instruct engineering students Expose students to unfamiliar engineering ideas Constraints • Stay within budget
Customers & Stakeholders Professor John Wellin Contact: jdweme@rit. edu Professor Ed Hanzlik Contact: echeee@rit. edu Engineering Professors and Faculty Engineering Students MSD Team
Customer Requirements • Requests 3 modules at minimum; 4 or 5 are preferred • Modules may be of different technical challenge and complexity • All modules must emphasize practical engineering experiences • Each module should be interesting to the students • • • Modules should bridge applications areas, such as electromechanical or electrochemical All modules should use commercially-off-the-shelf equipment to enable maintenance and sustainability of module use over many semesters of student enjoyment All module should have analysis challenges that are at or beyond student learning from core coursework
Customer Requirements Continued • All modules should be able to: • • Fully configured, utilized, and returned by student engineers Stand alone; contain everything they need without borrowing from other sources Have a high level of flexibility and expansion allowing for many engineering opportunities Be robust and safe

MEASURE OF AFFECTIVENESS Bloom's Taxonomy of Learning Survey Professors regarding modules to ensure they have a practical application to students future careers If modules branch into multiple disciplines All modules should bridge application areas, such as electromechanical All modules should have analysis Form a test group to determine the challenges that are at or beyond student complexity of the modules learning from core course work. Customer request 3 modules at a n/a minimum; 4 or 5 are preferred. All modules should be interesting to the MSD team interest students. Can be run by 1 student but can be up to 3 - -Determine number of tasks and complexity 4 students required for each module -Personal experience from MSDI Team will be considered Modules can use commercially-off-the-shelf Research and define what can be built by equipment to enable maintenance and the MSDI Team verses what can be bought sustainability of module use over many out of the total number of parts required for semesters of student enjoyment. the module All modules should be stand alone; they Test modules in lab setting should contain everything they need without borrowing from other sources. All modules must be robust and safe. Conduct testing on equipment and modules All modules should able to be fully configured, utilized, and returned by student engineers. Design and build an experimental apparatus equipped with appropriate measurement tools Conduct testing on equipment and modules Define measurement tools required for each module- (1) hardware (ie- controller boards, motors. . . ) (2) Software (labview, matlab, transducer specific programs)
Functional Decomposition Teach Mechanical Engineering Students about Engineering Principles Utilizing Student Designed Modules Provide the Problem Introduce Core Concepts Distribu te Lab Manual /Lab Abstrac t Show Videos/ Other Media Ask students to Make Modifications to Module Provid e Variabl es to chang e in the Modul e for the Stude nts Instruct Students to Establish a Theoretical Hypothesis Resear ch the Effect of Variabl es to Module Have Stude nts Hypot hesize Result s Provide Analytical Challenges Advise Students to use the Appropria te Analysis Tool Ensure module has proper complexityupper class level knowledge and strong depth of analysis Take all measur es to make sure module is present ed in an interesti ng way to student s Provide Experimental Challenges Design in way so students can make various permutati ons to the module while still learning core concepts Ensure modules are designed in a way to minimize risk of injury Ensure results of experimen tal challenges are independe nt of student’s lab skills Hand out Test Procedures Inform Students to Construct Test Oversee Run of the Tests 2/12/14
Criteria For Modules Criteria Measure Include extension of core courses with some knowledge from unavailable classes Complexity Lab Skills Measurable 1 - Core course Include non-required 2 - Core Course Plus Course Information along 3 - Elective with core course 4 - Beyond Capability, information outside learning 1 - Results Dependent on Skill (Time consuming for inexperience) 2 - Skill has an noticeable affect on outcome of Students must be able to results set-up an experiment and 3 - No skill is needed to measuring instruments get results (set ups are preset) 4 - Skills have minimum affects on outcome of results (Time for set up is minimal) Depth of Analysis required for module Complies with safety regulations Safety Reduce Risk of Injury Notes Level 4 More than acceptable, information can added 1 - One Variable 2 - 2 -3 variables 3 - 4 -5 variable Moved to 4 - combinational variables complexity Depth of analysis required duration Complies with safety regulation 1 - Requires Supervision 2 - needs special knowledge of operation 3 - needs notification 4 - simple working since Severity needed Variables Offer multiple configurations of module Grade
Criteria For Modules Criteria Measure A variety of topics are incorporated within the module Measurable Use Google entry counts, video views, search amount Look at past application labs to see trends Interest Module interesting to MSD Team ranked by relativity Exposure to an unfamiliar idea or topic not completely covered in core ME classes Cost to make module must be reasonable/ Within Budget Constraints Budget Contains Reusable Parts Of the shelf Parts Module can be completed with 3 -5 weeks Time Grade 1 - 1, 000 views not as interesting 2 - 50, 000 views interesting 3 - 1 million views very interesting 1 -Experience every day 2 -Experience is known but not common 3 - Related to regular day with minimal knowledge 4 - Related and captivating to student subject is relevant Notes 1 -Needs all custom parts with a heavy price tag 2 - Need minimal custom parts 3 - Most parts are off the shelf, some custom parts 4 - All parts are off the shelf, affordable/reasonable custom parts In house Manufactured Time needs to be split into two, analytical and experimental. Experimental can't be ran for 4 -5 hours.
