AN INTEGRATED OCCUPANT PACKAGING STUDY FOR A RACE CAR A.1 INTEGRATED COCKPIT DESIGN TRANSPORTATION Focus: to incorporate Digital Human Modeling (DHM) early stages of the vehicle development and to improve About: This study was held as an integrated concept vehicle development driver posture comfort (in terms of joint angles and vision) without sacrifjcing structural integrity. research project at European Ford Design Studios. I was asked to demonstrate an integration showcase of Digital Human Modeling (DHM) and Virtual Methodology: consist of using my Human-in-The-Loop design framework for modeling and simulation, and Reality (VR) for a concept vehicle development. utilize Virtual Reality (VR) tools to extend the advance visualization techniques during design process. Engineering Industrial Results: joint angle discomfort were improved while maintaining the aerodynamics and structural integrity of the vehicle. Center of gravity was further lowered. Form Function Future Work: includes a total-vehicle integration design study, which aims to form a high fjdelity digital Concept Proof vehicle design system that manages and monitors engine simulation, steering controls, suspensions with DHM.

A REVERSE ENGINEERING OF AN EMERGENCY CODE CART A.2 VERSATILE CODE CART HEALTHCARE Focus: to create a user-friendly, light-weight, easy to use and a safe code cart to accommodate needs and About: This study was a collaboration between Purdue University and limitations of nurses coming from different anthropometric backgrounds. Franciscan St. Elizabeth. I was asked to design a user-friendly, safe, lightweight and versatile code cart, which replaces current cart models, and would Methodology: creating human-machine-interaction simulations for patent pending unique features (such as accommodate nurses coming from different anthropometric backgrounds. bi-directional drawers, adjustable handles...etc.) through my Human-in-The-Loop design framework. Engineering Industrial 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. Form Function Future Work: fjnalizing patent application, developing marketing/sales plans and creating manufacturing Concept Proof drafts for a possible large scale production opportunity. Biomechanical Simulation of Push-Pull Movement (Strain Forces & Vision) INITIAL PUSH POSTURE IMPROVED PUSH POSTURE (CURRENT CART MODEL) (PROPOSED CART MODEL) Patent Pending Unique Features Adjustable Handles Poor Static Strenght results (high strain forces applied on body corresponding segments) Nominal Static Strenght results (average strain forces applied on body corresponding segments) Good Static Strenght results (low strain forces applied on body corresponding segments) Rear Section Frontal Section Bi-Drectional (Dual-Way) Drawers with T ranslucent Faces Current cart model creates cluttered vision Proposed cart model eleminates cluttering problem .5 pg.6
USER-FRIENDLY WASH-MACHINE A STUDY OF DESIGNING FOR HUMAN VARIABILITY CONSUMER GOODS A.3 Focus: to improve posture when loading-unloading of clothes of user groups coming from a wide-range of About: This consumer product design study was a collaboration between anthropometric population by utilizing Digital Human Modeling (DHM) during product development cycle. Whirlpool Corporation and Purdue University. I was asked to design a “wash-machine for all” around the requirements generated from consumer Methodology: to generate digital postures based on user study (data collection) and develop human- studies and technology integration. machine simulations by using Human-in-the-Loop design framework to fjnd optimized geometry. Engineering Industrial Results: door inlet size was increased for ease of access, pedestal height was optimized for different users, and overall dimensions of the wash-machine was fjnalized. Form Function Future Work: to develop future wash-machines that accommodate different needs and offer comforting Concept Proof features for users.
