OVERVIEW





BRIEF



The objective was to use an existing vehicle and ergonomically evaluate its design. The essential aspects of choice of the product were that there must be sufficient ergonomics evaluation available and it must be possible to build a representative model in SAMMIE/NX11.



DELIVERABLES



  • Siemens NX11 Model
  • Renders of model
  • SAMMIE Model
  • 20 Page report


OUTCOME



The current design of the ambulance does fit most user needs when critically evaluating the ergonomics of the two main sections (cabin and driver area). The investigation found that the 5th percentile frequently couldn’t reach items in the ambulance while the 95th percentile was frequently having to bend their neck a lot in order to look at the patient.

ERGONOMICS ANALYSIS SUMMARY





The ergonomic analysis for this proejct consisted of comparisons of the 5th and 95th percentile male and female models and whether they could conduct a number of tasks realted to ambulance usage. The examples below show some of the analysis condeucted:



Reach analysis of various items in the cabin



Reach analysis in a standing position in the cabin



Patient handling the cabin



Driver reach capabilities



Driver vision out of front of vehicle



Driver vision in side mirrors of vehicle



Passanger reach capabilites



Design change of stretcher to make it adjustable
