  1. Ergonomics: Design Principles or Axioms • General Guiding Principles or Thought Processes • Simple But Powerful Concepts • All Detailed Design Goals and Objectives Derive From Basic Design Axioms • Basic Design Axioms are More Important to Remember Than More Specific Solutions

  2. Ergonomics: Design Principles for Workstations • Do Not Lower That Which Must Be Lifted • Do Not Lift That Which Must Be Lowered • Use Gravity - Do Not Oppose It

  3. Design Principles and Rules of Thumb • Provide Adequate Space to Turn the Whole Body • Do Not Reach Behind • Avoid Extremes of Joint Movement • Avoid Postural Extremes

  4. Design Principles • Allow Natural, But Changing Postures • Avoid Static Loading of Muscles • Preserve the Natural Curves of the Spine

  5. Design Principles • Apply Force Dynamically, Conserve Momentum • The Lower the Reach Target, The Better the Shoulder Posture • Work Should Be 2 - 4 Inches Below Elbow Height, In General • Do Not Lift the Elbow • If Workers Must Reach Up and Out, Keep the Reach Below Heart Level • Pivot Movement About the Elbow • Keep Arm Motions Within the “Normal” Working Area

  6. Design Principles • Give Support To the Body • Avoid Contact Stresses • Reduce Repetition (enlarge jobs, rotate, mechanize) • Reduce Force • Power With Motors - Not With Muscles • Avoid Vibration - Especially Resonate Frequency Ranges

  7. Design Principles • Provide Adjustability • Fit a Range - Not the Average • Accommodate As Wide A Range as Possible

  8. Design Principles • Match the Tool to the Task • Handles Should be Smooth, Non-Conductive, and Compressive • Design For the Person With the Least Strength • Match the Grip to the Worker Population • Spread Contact Over Several Fingers - Not Just One

  9. General Approaches to Solving Ergonomics Problems • Eliminate the Need for the Task • Convert the Task to a Less Stressful Task • Mechanize the Task • Automate the Task - Assign the Task to a Machine

  10. Solving Ergonomics Problems: Lifting • Convert the Lift/Lower to a Push/Pull • Convert the Lift and Carry to a Push/Pull • Mechanize the Lift/Lower (Operator Guided, Machine Lifted) • Automate the Handling Task
