Mechatronics Definition „A mechatronics system is the synergistic integration of mechanical, electrical, electronics and embedded software technologies into electro mechanical products. Mechanical Electronics Mechatronics Electrical Embedded Software 3 UGS Corp. 2007. All rights reserved.

Some Facts „ „ „ Rapidly Increasing Functionality „ Increased package and PCB density „ 80 90% of new functions are electronics based1 „ Rapidly changing technology „ Increased on board diagnostics „ Software based functionality Growing Networks „ Hundreds of kilometers of wires in an aircraft „ Complex interconnections Tighter Physical Constraints „ Smaller enclosures „ Increased number of components „ Electromagnetic interference „ Non planar, flexible circuitry UGS Corp. 2007.

Challenges associated with Wire Harness Design Process „ Developers designed and located each sub assembly in the system with little consideration of the physical and electrical constraints of cabling „ Determine precise routing and length of cable through trial and error „ Synchronization of mechanical and electrical design data „ Lack of Interoperability between tools „ Disciplines use different data management „ Disciplines use different design processes „ Lack of or no smooth flow of data across all phases „ Lack of Change control „ Lack of support for Option and Variant management of Max complexity wire harness UGS Corp. 2007. All rights reserved. 9

Evolution of Wire Harness Design „ Some of the challenges are addressed by integrating ECAD system with Mechanical 3 D modeling system „ Precise Routing PLM XML RouteList / NX4 „ Exact length of Cable & Bundle data Mechatronics PLM XML / NX4 „ Interference checks „ Design Rule Validation File based: NX4, „ Lack of integrated workflow resulting „ Duplication of design data „ Modification of data is error prone and time consuming. „ Lack of change control „ Point to point integration between multiple design tools 10 UGS Corp. 2007.
