TRANSPORTATION

Focus: to incorporate Digital Human Modeling (DHM) early stages of the vehicle development and to improve driver posture comfort (in terms of joint angles and vision) without sacrifjcing structural integrity. Methodology: consist of using my Human-in-The-Loop design framework for modeling and simulation, and utilize Virtual Reality (VR) tools to extend the advance visualization techniques during design process. Results: joint angle discomfort were improved while maintaining the aerodynamics and structural integrity of the vehicle. Center of gravity was further lowered. Future Work: includes a total-vehicle integration design study, which aims to form a high fjdelity digital vehicle design system that manages and monitors engine simulation, steering controls, suspensions with DHM. Posture Improvement Study Based on Joint Angles through DHM Assembly Simulation in Virtual Reality with CAVE Integrated CAD Model with DHM Integrated CFD with DHM

INITIAL POSTURE IMPROVED POSTURE

Y ellow indicates posture angles out of comfort range Green indicates posture angles are within comfort range

Industrial Engineering Form Concept Function Proof About: This study was held as an integrated concept vehicle development research project at European Ford Design Studios. I was asked to demonstrate an integration showcase of Digital Human Modeling (DHM) and Virtual Reality (VR) for a concept vehicle development.

Patent Pending Unique Features Biomechanical Simulation of Push-Pull Movement (Strain Forces & Vision)

Nominal Static Strenght results (average strain forces applied on body corresponding segments) Good Static Strenght results (low strain forces applied on body corresponding segments) Poor Static Strenght results (high strain forces applied on body corresponding segments)

IMPROVED PUSH POSTURE

(PROPOSED CART MODEL)

Current cart model creates cluttered vision Proposed cart model eleminates cluttering problem Bi-Drectional (Dual-Way) Drawers with T ranslucent Faces Adjustable Handles Rear Section Frontal Section

Engineering Function Proof About: This study was a collaboration between Purdue University and Franciscan St. Elizabeth. I was asked to design a user-friendly, safe, lightweight and versatile code cart, which replaces current cart models, and would accommodate nurses coming from different anthropometric backgrounds. Industrial Form Concept Focus: to create a user-friendly, light-weight, easy to use and a safe code cart to accommodate needs and limitations of nurses coming from different anthropometric backgrounds. Methodology: creating human-machine-interaction simulations for patent pending unique features (such as bi-directional drawers, adjustable handles...etc.) through my Human-in-The-Loop design framework. Results: percent capable summary of upper and lower limbs were improved and visual obscuration (cluttler) zones were cleared. Proposed cart model accomodates a wide range of nurses comparing to current models. Future Work: fjnalizing patent application, developing marketing/sales plans and creating manufacturing drafts for a possible large scale production opportunity.

USER-FRIENDLY WASH-MACHINE A STUDY OF DESIGNING FOR HUMAN VARIABILITY A.3

CONSUMER GOODS

Focus: to improve posture when loading-unloading of clothes of user groups coming from a wide-range of anthropometric population by utilizing Digital Human Modeling (DHM) during product development cycle. Methodology: to generate digital postures based on user study (data collection) and develop human- machine simulations by using Human-in-the-Loop design framework to fjnd optimized geometry. Results: door inlet size was increased for ease of access, pedestal height was optimized for different users, and

• verall dimensions of the wash-machine was fjnalized.

Future Work: to develop future wash-machines that accommodate different needs and offer comforting features for users. Digital Posture Construction from Usability Study Comparison between Design Alternatives Inlet Door Validation through DHM
