Which of the following best explains the benefit of using ergonomics in product design?

Using ergonomics in product design primarily focuses on enhancing user satisfaction and comfort. This approach ensures that products are tailored to fit the physical and cognitive abilities of the end-users, making interactions more intuitive and less strenuous. When products are designed with ergonomic principles, they often reduce the risk of discomfort or injury associated with prolonged use, thereby improving user experience.

Additionally, ergonomic design can lead to increased effectiveness in how users interact with products, making tasks more efficient and enjoyable. This can contribute to higher user satisfaction, as the product feels more natural and is easier to use over time. Thus, the emphasis on human-centered design through ergonomics directly correlates with improved comfort and overall satisfaction in daily usage.

In contrast, the other options, while potentially relevant to product design, do not capture the primary goal of ergonomics, which is to prioritize the user experience. For instance, ergonomics may not directly influence production speed, material costs, or manufacturing complexity, as these factors are more often associated with overall production efficiency and management rather than user interaction and comfort.
