Study Notes
Ergonomics
- Scientific field focused on understanding interactions between humans and their environment.
- Aims to design systems and products that are safe, comfortable, and efficient for users.
Scope of Ergonomics
- Designing man-made systems, including those involving computers.
- Designing consumer goods and services.
- Designing work environments.
Categories of Ergonomics
- Physical Ergonomics: Focuses on human anatomy, anthropometry, physiology, and biochemistry.
- Psychological Ergonomics: Studies mental processes, including perception, cognition, and workload.
- Organizational Ergonomics: Optimizes organizational structures and processes.
Ergonomics Risk Factors
- Posture: Awkward postures can lead to musculoskeletal disorders.
- Force: Exerting excessive force can strain muscles and joints.
- Frequency: Repetitive movements can contribute to musculoskeletal problems.
Importance of Ergonomics
- Increased Productivity: Ergonomic solutions enhance worker efficiency and productivity.
- Reduced Costs: Ergonomics investments can save money by decreasing employee absences and accidents.
- Improved Work Quality: Comfortable and safe workplaces lead to higher quality work.
- Reduced Absenteeism: Ergonomics helps reduce illness and absences due to musculoskeletal disorders (MSDs).
- Worker Assurance: Ensures worker safety and well-being.
Principles of Ergonomics
- Maintain Neutral Posture: Keep the body aligned and balanced, avoiding awkward positions.
- Work in the Power/Comfort Zone: Utilize the "handshake zone" for optimal reach and effort.
- Allow for Movement and Stretching: Regular stretching reduces fatigue and promotes blood flow.
- Keep Things Easy to Reach: Minimize unnecessary reaching and stretching.
- Reduce Excessive Force: Limit the amount of force required for tasks.
- Reduce Excessive Motion: Decrease unnecessary movements.
- Minimize Contact Stress: Avoid prolonged pressure on specific body parts.
- Provide Clearance: Ensure ample space for movement and activity.
- Reduce Excessive Vibration: Minimize vibration exposure to reduce discomfort and health risks.
- Provide Good Lighting Conditions: Adequate lighting improves visual clarity and reduces eye strain.
Ergonomic Process
- Assess Risk: Conduct ergonomic assessments to identify potential hazards.
- Plan Improvements: Develop solutions to address identified risks.
- Measure Progress: Track the effectiveness of implemented changes.
- Scale Solutions: Expand successful ergonomic practices to other areas.
Ergonomics Design Guidelines
- Flexible interior planning.
- Applying the kitchen work triangle principle for efficient workspace layout.
- Choosing appropriate equipment, ventilation, and lighting.
- Creating sufficient space for smooth workflow.
- Implementing effective tidying and storage systems.
Storage Area Design
- Food Storage: Designated area for storing perishable items.
- Dry Storage: Area for storing non-perishable items.
- Cold Storage: Area for storing refrigerated or frozen items.
Elements and Principles of Design
- Design: The translation of a concept, idea, or theory into a tangible form.
- Elements of Design: The basic components used to create a design (e.g., line, shape, color, texture).
- Principles of Design: The guidelines for combining elements to create a cohesive and effective composition (e.g., balance, rhythm, unity, emphasis).
