  1. Custom Ergonomic Workstation Group 3 Jim Herbst Jr. BME 272/273 2001-2002 2nd Oral Presentation 2/27/02 Dr. Paul King Dr. Ed Glaser

  2. Objectives • Design and prototype the first complete one-piece fully customized ergonomic workstation • Invent a casting process which can be administered in a doctor’s office • Reduce office injuries related to a sedentary lifestyle

  3. Market Potential • Growing amount of computer-based jobs • Growing amount of posture-related injuries • Growing awareness of ergonomics

  4. Revised Target Market • Those who spend 4 hours of more at a computer each workday • Individuals who have serious back problems • Individuals who frequent chiropractor

  5. Thoughts From 1st Oral • List problems of current chairs • Insurance issues • Biomechanics goal • S-Curve

  6. Problems of Current Chairs • Most users are not educated to take advantage of adjustments • Generic seat designs do not suite the individual

  7. Insurance Regulations • Resident chiropractor noted that there should not be a problem with coverage • Those who are interested in chair will be willing to pay since they have invested much money into their back already

  8. Habitual Posture • Influences kinesthetic awareness • Sitting posture • Stretches shoulder blades and back • Shortens chest, hips, and shoulders • “Normal” posture places low back in a lordosis

  9. Biomechanical Goal • Provide therapeutic benefit • Reduce muscle energy expenditure • Place back in a neutral alignment

  10. Anatomy of the Back • Normal curvature is S-shaped • Curvature can deviate due to muscular imbalance • 80% Americans have faced low back pain • Ages 25-60 have highest probability to complain

  11. Posture and Muscle Imbalance • Muscular imbalances manifest themselves in a person’s posture and alignment • Neutral alignment is best equipped to deal with external stress and strain • Neutral alignment results in the least amount of muscle energy

  12. Postural Deviations

  13. Classic Postural Deviations • Kyphosis-lordosis • Increase in inward curvature of low back • Outward curvature of thoracic spine • Flat back • Decrease in normal inward curve of low back • Pelvis in a posterior tilt • Sway-back • Long, outward curvature of thoracic spine • Scoliosis • Lateral curve of spine

  14. Lordosis: A Closer Look

  15. What We’ve Done So Far • Patent search • Internet search • Brainstorming casting techniques • Creation of primary casting prototype • Creation of secondary casting prototype • 1st seat prototype

  16. Creation of Secondary Casting Prototype • Fix mistakes of first prototype • More comfort • Better posture

  17. First Prototype of Chair Back

  18. Chair Back Cont.

  19. Future Work • Pad chair • Attach Legs • Attach Arms • Comfort Test • Revise • Create Compatible Workstation
