P08351 – Concept Design Review Automated Oiling System
Agenda • 1:00-1:15 Overview of project • 1:15-1:50 Mechanical Engineering subsystems • 1:50-2:10 Electrical Engineering subsystems • 2:10-2:25 Proposed integrated system • 2:25-3:00 Open Discussion/ action & issues
What's the problem? • Parlec currently manufactures a wide variety of tool holders • The following process currently exists: • Manually dip • Manually drain • Stand on paper towels to dry Resulting complications: excess labor required (2-3 workers) oil waste part coverage inconsistency hinder ability to meet throughput
Window of opportunity • In response, Parlec has requested a machine to automate the oiling process.
Concept Selection • Concept Generation: Breakdown subsystems even further, develop possible solutions and corresponding pros and cons • Concept Screening: Develop a list of applicable selection criteria and use Pugh’s Method to compare possible solutions • Concept Scoring: Apply weights to each individual criterion in order to confine results to one or two possibilities.
Mechanical Engineering Subsystems • Loading/Unloading • Oil Application • Part Cleaning • Remove excess oil
Electrical Engineering Subsystems • Variable Speed Drive System
Mixed Signal Input Discrete variable Continuous variable
Integrated Solution • Loading/Unloading : hooks, tight fitting, loose fitting fixture • Oiling: Dip and spray • Cleaning: Air and rags • Remove excess oil: Air and drip • VSD System: AC/DC with prebuilt drive and AC with custom drive
