Wire Harness Design

Because of the growing functionality in the vehicle the wire harness design is becoming more complex

The number of wires routed in the vehicle makes the bundle more stiff and isn’t the wire harness that flexible anymore and we should count with that in the packaging claim. Electrical vehicles are entering the market, which requires a renewed strategy in vehicle wire harness design because of the high voltages present during fast charging.  In the high-tech industry the required accuracy and increasing throughput demand is making the machines more complex. The number of electronic-boards is growing exponential and connectivity is becoming more and more complex. The number of variants to manage as well as maintenance documentation is  another challenge in wire harness design.
 

Segula Technologies as international group recognize these trends and offers their customers a professional way of working regarding wire harness design. The resident engineer as a single contact person will be present frequently at the customer location in order to discuss functions and features that will be supported by the wire harness, design rules, environmental requirements, etc. The resident engineer is responsible for defining and releasing the work package that will be designed at the Segula office according to the standards of the customer. The complete development life cycle of the wiring harness design will involve function/feature definition, physical architecture, schematic entry, 3D modelling, 2D drawings, form board design, service and maintenance documentation. However Segula can also support in the cases of only a need for 2D drawings, BOM and cut sheet.

To be able to manage complex wire harness designs Segula will select the appropriate tools and techniques along the development axis as D-FMEA, DFA, DFM, change management and variant management. Critical design parameters will be discussed and simulations on critical issues will be carried out to support the development in progress.
