COMPUTER AIDED MACHINE DESIGN: CASE STUDY ON THE DESIGN OF A MATERNITY DELIVERY BED

ABSTRACT

The high maternal mortality rate in Kenya is of a huge concern and it requires the attention of both the government and private sector in offering solutions. According to research, one of the main causes of the high maternal mortality rate is inadequate hospital equipment. Most hospitals either lack or have insufficient medical equipment that are necessary during labor and birth. The maternity delivery bed is one of the medical equipment that is needed during the delivery process. This means that investment in it would have a direct impact on the maternal mortality rate. In a move to salvage the situation, this project was meant to design a functional and affordable maternity bed for use locally.

The project started by collecting information from the affected parties to have a clear picture of what needed to be designed. Quality Function Deployment (QFD) was implemented to ensure a thorough understanding of customer requirements before commencement of the design phase. Computer aided machine design was then used to come up with a maternity delivery bed design that will ensure ease of fabrication and subsequent maintenance. The new design paid special attention to ease of use, customer satisfaction, and affordability. The completed design was then passed through rigorous testing involving tests such as fatigue test in a simulated environment. This project was undertaken in a move to ensure that maternity delivery beds can be fabricated and maintained locally at an affordable price. The final design proved to be competitive in many aspects when compared to existing beds in the hospitals and those available in the market. In the event that the new maternity delivery bed design is developed further, it is expected to have a major impact on maternal mortality by making the birthing process safer and more affordable for expectant mothers.
