Abstract: This study explores the impact of cognitive psychology and human factor engineering on mechanical engineering, focusing on user ratings and expert evaluations to determine product sustainability. Utilizing a mixed-methods approach, by collecting data on 30 products from user surveys assessing mental effort, ergonomics, user satisfaction, user interface, and aesthetics. Additionally, expert ratings on the sustainability potential of these products were gathered. Correlation and regression analyses were performed using IBM SPSS to identify significant predictors of sustainability. The results indicate that ergonomic design is a significant positive predictor of sustainability potential, aligning with the literature that emphasizes the role of ergonomics in enhancing user comfort and reducing physical strain. User satisfaction and aesthetic appeal also showed strong positive correlations with sustainability. Although cognitive load (mental effort) did not directly predict sustainability, it significantly impacted ergonomic design and user satisfaction, which in turn correlated strongly with sustainability. These findings underscore the importance of integrating ergonomic principles, enhancing user satisfaction, and incorporating aesthetic appeal in product design to ensure market success. The study highlights the indirect influence of cognitive load on sustainability through its impact on ergonomic design and user satisfaction. Future research should address the study’s limitations, such as the sample size and the limited pool of expert ratings and explore additional factors influencing product sustainability. This research provides valuable insights for designers and engineers, emphasizing the critical role of human factors and ergonomic principles in creating sustainable products that meet user needs and preferences.
