Design ergonomics, or product ergonomics, refers to the application of ergonomics principles from the initial stages of product development. The main goal of design ergonomics is to develop end products that are intuitive, safe, efficient, and comfortable for users— whether that end product is a cellphone, tv remote, machine control panel or equipment like lift tables.
Ideal Outcomes in Ergonomics Design
Usability in Design: The product should be easy to use and understand, even for users without specialized training. This involves the layout of controls, adequate visual and tactile feedback, and the logic of the product’s operation.
Safety in Design: The design should minimize the risk of injuries or damage to users during normal use. This includes postural ergonomics (avoiding awkward postures), the robustness and durability of the product, and the presence of appropriate warnings and protections. The Design Guidelines for Ergonomics were developed with the goal of reducing musculoskeletal disorder (MSD) risk factors during the design phase of products, tools, assembly lines and machines.
Efficiency in Design: The product should allow users to perform their tasks efficiently and without excessive fatigue. This involves optimizing workflows, minimizing unnecessary movements, and ensuring adequate response times to user commands. When using the Design Guidelines for Ergonomics to adjust postures and reduce the range of movement, it will positively impact efficiency for the task, considering that you may reduce the time to perform that movement.
Adaptability in Design: Variations in user abilities and physical characteristics are considered. The design should be adaptable to accommodate different types of users, such as people with varying heights, motor skills, or special needs.
Feedback and Control in Design: It is important that the product provides clear feedback on its actions and that the controls are intuitive and responsive.
Design ergonomics usually involves collaboration between industrial designers, engineers, ergonomists, and end users to ensure that the product meets ergonomics requirements from the beginning of the design process. This not only improves the user experience but can also reduce costs related to design failures, rework, and customer dissatisfaction.
