Designing an Ergonomic Workstation: A Comprehensive Approach to Comfort and Health

This presentation explores the development of a fully customized ergonomic workstation aimed at reducing office injuries associated with sedentary lifestyles. The design integrates innovative casting processes suitable for doctor’s office implementation, ensuring personalization for individuals spending extensive hours at their computers. It addresses prevalent issues with current seating solutions, emphasizing the importance of biomechanics and proper posture. Key findings from research, including market potential and the impact of muscular imbalance on health, are discussed to demonstrate the increasing necessity for ergonomic solutions.

  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
