It is increasingly necessary to develop products that are oriented toward not only economic sustainability but also social and environmental sustainability. In this article we illustrate application of the Ergonomics Quality in Design (EQUID 4.0) model in the design and development of a personal protection item for improving working conditions in one of the most common and harmful activities in Latin America: kneeling work in agriculture, construction, and mining. We conclude that the model reinforces the possibilities for ergonomics to support product design and development beyond physical and cognitive dimensions, and we reflect on the experience.
Lange-Morales et al. (2026) studied this question.
