  Challenges of enhancing productivity by amplifying efficiency and man-machine
compatibility of equipment can be achieved by adopting advanced technologies.
This study aims to present and exemplify methodology for incorporating
ergonomics pro-actively into the design using computer-aided design and digital
human modeling-based analysis. The cleaning equipment is parametrized to detect
the critical variables. The relations are then constrained through the 3DSSPP
software-based biomechanical and experimental analysis using a prototype.
MATLAB and Minitab software is used for optimizing efficiency while satisfying
the established constraints. The experiment showed nearly 67%, 120%, and 241%
successive improvement in the mechanical advantage in comparison to their
immediate predecessors. A significant (6 point) reduction in rapid entire body
assessment score has been observed in the final posture while working with the
manipulator. 3DSSPP suggested that the joint forces during the actuation of the
manipulator were acceptable to 99% of the working population. The study
demonstrated the potential of the methodology in revamping the equipment for
improved ergonomic design.
