A student support program at a major urban university has three main objectives: (1) To increase thenumber of Hispanic and low income students who transfer from junior colleges (2) To increase thenumber of Hispanic and low income students who join the university as upper division transfers, andobtain degrees in a reasonable timeframe (3) To develop a sustainable model, for others to follow, thatwill result in a transfer program to service the students mentioned above.In order for this program to succeed, it is necessary for articulation agreements to exist betweenuniversities and the junior colleges that feed students to it. For students to transfer as upper division,freshman and sophomore classes must exist to allow for transfer in a reasonable time period, whilemeeting the strict requirements set forth by universities. With respect to Mechanical Engineering (ME),this includes a design component as each class within its design sequence now contains some level ofdesign methodology.Because of the time needed to complete articulation, students currently in the support program whoare ME students did not receive the necessary design component in certain classes taken at juniorcolleges. In order to make up for this deficiency, a summer-long design clinic was held for thosestudents, and provided the necessary information required for complete integration into the ME designstem.This paper discusses the design experience. More specifically: Under the supervision of the supportprogram advisor, a group of students was given the task of designing and manufacturing an intakemanifold for an internal combustion engine. The students followed the standard design protocol ofconceptual, preliminary, and critical design and presented their design through the review process.Upon completion, a wax-impregnated model was created using a Zcorp® rapid printer, from which amold was made using the lost wax process. After burnout, an aluminum casting was poured with theresult being a manifold in the as-cast form. Numerous machining operations followed which includedcomplicated fourth-axis machining of various surfaces, as the manifold is a very complicated part.Ultimately, the students performed flow analysis on the manifold which demonstrated an improveddesign, and provided their findings in final report form.
