3D wire harness topology exploration and optimization


  With easy-to-use cost and weight evaluation and modification capabilities, Zuken’s E³.WiringSystemLab enables a substantial reduction of ramp-up and optimization cycles for wiring harness engineers.
  E³.WiringSystemLab provides optimization capabilities of imported wire harness designs: add/delete bundles and route pathways (1), change position of components, splices and ground bolts (2), modify partitioning of harnesses (3)

Optimizing wire harness designs to meet targeted weight and cost objectives is a complex and challenging task. One of the most time consuming aspects is the consolidation of different data sources and inputs into one consistent representation. Topology data, in particular, have been known to require an intense effort for consolidation, as different segments have to be combined to a single representation and then routed manually in a 3D environment (e.g. CATIA® or Siemens NX®). Zuken’s innovative E3.WiringSystemLab simplifies this complex task with direct 3D data modelling capabilities and automated wire harness assembly functionality supporting the compilation of comprehensive harness designs from heterogeneous fragments. The result is a substantial reduction of ramp-up and optimization cycles.

Areas of application

E3.WiringSystemLab enables the optimization of wire harnesses with an unprecedented degree of speed and accuracy. With these capabilities, it generates substantial benefits across a wide spectrum of applications in the automotive and transportation industry.

E3.WiringSystemLab integrates seamlessly into existing E3.series environments, reading in schematics data directly from the E3.cable data model. In addition, standard interfaces such as KBL, VEC, PLMXML, as well as generic Excel files, are supported. With these capabilities, E3.WiringSystemLab also lends itself to system optimization tasks that are embedded into third party environments.

Supported Formats

E3.WiringSystemLab is committed to supporting all relevant industry standard formats.

With its support of the VEC format, E3.WiringSystemLab leads the industry by anticipating the next generation industry standard for wire harness designs. For the customer this means substantial benefits in terms of easy integration into existing environments as well as a protection of investments in legacy data.

E3.WiringSystemLab seamlessly integrates into E3.cable. Information between the toolsets is provided by a process-to-process coupling. No file transfer is required to read in schematic information into E3.WiringSystemLab. A highlighting functionality enables cross-probing between E3.WiringSystemLab and E3.cable. This cross reference is also maintained through the technology repartitioning process and ultimately becomes available in E3.HarnessAnalyzer in combination with the related 3D structure.

Direct modification of 3D data

Topology structures can be accessed and manipulated directly in a 3D environment. An intuitive user interface enables casual users to access and modify 3D structures without requiring specialist training.

Powerful, yet easy-to-use functionality is also available to support typical topology modification tasks, such as inserting connectors, packaging components by drag and drop or 3D mirroring.

Concept Compare

E3.WiringSystemLab provides powerful concept evaluation capabilities to compare different implementation approaches.

An online-indicator is available directly in the user interface, with which trends for key values can be indicated. Details can be accessed with just one additional click. In addition a dedicated comparison tool is available that visualizes differences between versions on a detailed level down to single wires or connectors.
