Study Notes

Ergonomics Design Relationship

The relationship between ergonomics and design is closely related to the scientific understanding of human interaction with different components of a workplace or system.
Ergonomic design focuses on optimizing workplaces, products, and businesses to suit the people who use them.

User-Centred Design (UCD)

This approach considers the user's perspective and accounts for their preferences and needs during the design process.
The stages of UCD include Understanding context, Establishing requirements, Designing solutions, and Testing and evaluating.

Human-Centred Design (HCD)

HCD focuses on making systems and products usable and useful by prioritizing user needs, requirements, and contextual knowledge.
The core steps involve Empathizing, Defining, Ideating, Prototyping, and Testing.

Benefits of Human-Centred Design

Better employee engagement as they feel ownership in the design.
Improved productivity due to easier understanding and use.
Enhanced user experience through increased worker involvement.

Ergonomic Design Models

Sociotechnical System Model: This model acknowledges the complexity of people, organizational structures, technology, and technical processes.
HWTH Model: Consists of inner and outer layers encompassing factors impacting ergonomic design in the workplace.
3C Design Framework: Aims for a balance between job demands, worker capabilities, and design demands to achieve desired outcomes like safety.
Human Factors and Ergonomics (HFE) Onion Model: Integrates all previous models, focusing on the interaction of factors within the workplace.
Conceptual Model of Ergonomic Practice: Examines the human-technology-workplace-environment factors in the workplace.
Work System Model: Emphasizes collaboration, creativity and connection through ergonomic design in the workplace.

Designing for Work Postures: The Standing Operator

Maintain a straight back posture while working.
Utilize adjustable desks to cater to worker height.
Avoid repetitive bending.
Minimize twisting positions as much as possible.
Keep tools and technology within the worker's reach.
Provide stools for frequent rests.
Ensure relaxed arms and shoulders.
Avoid twisting of hands and wrists.
Use footrests for enhanced comfort.
Maintain slip-resistant flooring.

Designing for Work Postures: The Seated Operator

Address the issue of sedentary behavior with seated operators.
Adjustable desks are crucial.
Encourage physical activity in the workday if adjustable desks are not available.
Account for individual differences in height and weight.

Designing for Work Postures: Seated Operator (Example)

What is right with this picture? The seated operator has good posture: back straight, legs at a 90 degree angle, feet flat on the floor, and arms at a comfortable working height.
What is wrong with this picture? The seated operator is hunched over, arms are not at a good working height, and there is no evidence of a footrest.
