MODULE A, etc. Design Modules• Mechanical – 3D CAD, Print, Test fit• Electrical – Standard Connector, Power, Communication• Optical – MT, Fusion Splice or Individual ConnectorBuilding Block Approach to Systems 7► Logical BlocksInterconnectBuilding Block Approach to Systems 9► Interconnect Electrical wiring harness: Straightforward to standard connector. Optical fiber centralization: Need a well-thought-out “Road Map.”Additive ManufacturingBuilding Block Approach to Systems 11► Additive Manufacturing Learning Curve Material / Cost Design Module –Get Drafting involved early Trial & Error Initial CostBuilding Block Approach to Systems 12► Additive ManufacturingTestingBuilding Block Approach to Systems 14► Testing Test Bed Test Procedures Individual Module• Power up with lab power supply• VI, need programing to test functionality, also needed for parameter tests Multiple Modules• Same needs for Individual Module, but the need to test portions of system comes into play. The need for operational modes when working with more than one module. System• Static• DynamicBuilding Block Approach to Systems 15► Test BedServiceabilityBuilding Block Approach to Systems 17► Serviceability Modules• Spares• Manageable complexity Installation• Repair time Spares• Tested and ready to use Complexity• Ease of fabrication K.I.S.SBuilding Block Approach to Systems 18► ServiceabilityTake AwayBuilding Block Approach to Systems 20► Take Away Serviceability• Spare blocks• Repair time• Need for an SME reduced Fabrication• Manageable complexity• Need for an SME reduced Is it right for you?Pros ConsModular design fits customer needUp-front costSpare blocks for quick replacement or repairEngineering expenseDrafting involved early Up-front design timeFabrication and repair can be done by non-SMEDesign must be mature*Long-term serviceability and sustainability* Frozen design of interconnect does not easily allow changes
