Before you get started
What will I get from Navigator?
Explore technical paths and candidates related to an engineering problem. Compare intended uses, applicability and sources, identify missing information and key questions, and download an assessment preparation summary. These outputs help you prepare your next technical assessment. Applicability still requires samples, measurements and supplier confirmation.

You can browse engineering problems, suppliers and solutions, and compare solutions without signing in. Sign in to save cloud copies of cases, view account-linked inquiry history, claim a supplier company, propose updates or reply with supplier authorization. Supplier permissions also require a reviewed claim or an owner invitation.

The supplier catalog is compiled from public sources. Problem-specific candidates include context for the problem, structure and stage. A listing or candidate does not establish verified applicability, supplier endorsement or a purchasing recommendation. Read the sources and limitations together, then confirm your conditions with the supplier.
