    August 19th 2021

    Long-running engagement with the world-leading medical technology specialist Stryker highlights Erdmann Design’s key strengths in Human-Centered Design (HCD) and Innovation Strategy.

    Erdmann’s work with Stryker Germany on several key projects, the NAV3i Operating Room Navigation cart and Mako Knee Robotic System, made demands on the HCD fundamental disciplines of Design Thinking for Marketability, Industrial Design, Usability Engineering and User Testing.

    Also tested in the Stryker projects was Erdmann’s Innovation Strategy approach based on market analysis-led Strategy Planning, UX Experience Mapping with stakeholders, and research-led Marketing.

    Stryker Operating Room Navigation Cart

    The highly innovative Stryker NAV3i Navigation System provides surgeons In modern operating rooms with screen-controlled navigation that has become an indispensable aid for highly complex and ultra-precise surgical interventions to the throat, nose and ears, hips, knees and back.

    Each operation plan can now be coordinated individually, taking the patient’s and the medical team’s needs in the OR into consideration.

    The overall design of the cart allows maximum flexibility in the OR when positioning the navigation elements in the room: a camera, two monitors, mobile computers and various interfaces.

    The consistent modular design of the Stryker Cart improves the whole user experience, including setup of operations, while standardization around use of available off-the-shelf components optimizes production, maintenance, and cost efficiencies, all enhancing market appeal.

    Erdmann Design contributed concepts and design services to the project, whose success has raised the international profile of Stryker Germany and emphasized its distinctly European heritage.

    Fruits of Erdmann Design’s inputs to the project can be seen in the design of the NAV3i Navigation System and Stryker Navigation Camera, along with the aesthetically sophisticated visual language and precise user guidance of the Stryker screen design and overall system ergonomics. These were key factors in the system winning design awards, including the German RedDot Design Award.

    Stryker Mako SmartRobotics

    Mako SmartRobotics combines three key components: 3D CT-based planning, AccuStop haptic technology, and insightful data analytics, into a single platform that has produced better medical  outcomes for total knee, total hip and partial knee replacement patients.

    The surgeon’s work with the Mako system, using the screen as a tool, requires clear language for user guidance and perfect connection between screen and user. Erdmann Design brought its experience in industrial design and graphic user interface (GUI) to bear on the project to form the Corporate Style Guide that defines the total user interface in the area of knee navigation.

    The distinctive user guidance, the visual appearance and the acoustic quality of the sound design were all successful, setting new standards for the medical design field.

    Together with the Stryker engineers and programmers, it was possible to develop a Style Guide which is used as a precise basis and example for developments in other areas.

    Engagement with Stryker

    Erdmann Design has partnered with Stryker since 1999 and over that time has contributed a range of specialized services to a wide range of sub-projects.

    These have involved disciplines that include Human Centered Design, Experience Mapping, workshops, industrial design, production documents, marketing seminars, market introduction, GUI design, audio design, pictograms, interactions, design workflow, UX standardization style guides, testing, and certification.
