National Science Foundation Industry/University Cooperative Research Center for e-Design NSF I/UCRC Center for e-Design Summer 2010 IAB Meeting 3 Problem Statement Small sized industry partners do not always have internal engineering design capabilities. A market opportunity exists for a more functional design. The process could enable the collaborative transfer of e-Design knowledge.

National Science Foundation Industry/University Cooperative Research Center for e-Design NSF I/UCRC Center for e-Design Summer 2010 IAB Meeting 4 Approach and Methods Three different potential design concepts identified: Cable on Pulleys Straps on Pins Roller Chain Option Use the e-Design Ontology’s framework for: – FEA and ANSYS analysis – Design decision process – Design optimization

National Science Foundation Industry/University Cooperative Research Center for e-Design NSF I/UCRC Center for e-Design Summer 2010 IAB Meeting 5 Related Works Drawbacks with current design: – Exhibits sway greater than 20” – Breakage of cables after about 350 cycles – Quick release can cause the mast to come crashing down Competitor products: – Costly – Rise to the 30 feet height can take significantly longer than the desired speed for the payload

National Science Foundation Industry/University Cooperative Research Center for e-Design NSF I/UCRC Center for e-Design Summer 2010 IAB Meeting 6 How Ours is Different Design process utilizes high end design methods and tools to verify and validate. Provides knowledge of the interoperability between two different CAD systems (Pro/E and Solid Works) Technology Transfer of design knowledge from UMass e-Design team to an industry partner Captures and maintains semantic information using UMass Amherst’s ontology-based e-Design framework

National Science Foundation Industry/University Cooperative Research Center for e-Design NSF I/UCRC Center for e-Design Summer 2010 IAB Meeting 7 Deliverables and Benefits Deliverable: – A completely developed and validated design specification to enable production. Benefits: – Ontology knowledge instance information – Sales in an initial estimated quantity of 1000 – 3000 – Creation of jobs in the Precision Machining sector of the Western Massachusetts region
