Solution for Wire Harness Design Cuts Cabling Weight, Size and Cost While Optimizing Performance

April 26, 2004 - By integrating the electronic and mechanical design environments, and enabling back- and forward- annotation between the two, Zuken's Wire Harness Design solution helps designers to cut the weight, size and cost of vehicle wiring looms. At the same time, it ensures optimized performance and delivers a significant reduction in overall design time by minimizing design iterations.

A mid-range car today has between 50 and 100 individual electronic systems that need to be linked by a wire harness, with around 2500 interconnects to be made. This design complexity results from the increased use of electronics in engine management, safety systems, in-car entertainment, and other peripheral systems in vehicles. Zuken's Wire Harness Design tool suite spans hierarchical schematic capture and definition of connector pin attributes, harness design and topology, 3D routing, and tight integration into the automotive industry's leading design and simulation solutions: CATIA V5 from Dassault Systemes and I-DEAS. The tools also provide design rule checking (DRC), variant management, and simulation and verification of the design.

Cabling Designer, the core tool within the solution, is used to design local wire harness connections between functional blocks and extends the capabilities of Zuken's advanced CR-5000 schematic and PCB design technology so that electrical and mechanical data are combined in a single 3D environment. Cabling Designer is complemented by a Variant Module to help define and manage variations in harness design between vehicle models, a Topology Designer to examine placement of functional units and routing in 2.5D, and a Harness Designer to generate manufacturing data. A CATIA V5 Interface Module facilitates high-level integration with 3D mechanical tools from Dassault Systemes. It realizes collaboration design between CATIA V5 Wire-harness routing design features and Cabling Designer. In addition, a Simulation and Verification Module can analyze the electronic characteristics of the schematic and harness design across the complete system. Finally, Wire Harness Desktop is the command center where a user-friendly interface allows switching between several views including specifications, variants, logical schematics and assembly.

Zuken's Wire Harness Design solution is intuitive and easy-to-use; it is proven and built upon established core technology, and offers a hierarchical data structure for effective design management. Furthermore, the solution is based on a constraints-based design methodology and design rule checking (DRC) that ensures right-first-time design and manufacturable-first-time outcomes.

Zuken's Wire Harness Design solution is available now and is priced from $20,000. CATIA® is a registered trademark of Dassault Systèmes. +++ends
