1 What is CAD quality and reliability analysis?

CAD quality and reliability analysis is the application of various methods and techniques to evaluate and improve the quality and reliability of a medical device using CAD software. This software allows designers and engineers to create, modify, and test digital models of the device, as well as simulate its behavior and performance under different conditions. CAD quality and reliability analysis can involve activities such as design for reliability (DFR), which involves meeting reliability requirements and specifications, as well as preventing or mitigating potential failures and risks. Additionally, failure mode and effects analysis (FMEA) is used to identify and assess possible failure modes of the device, their causes and effects, severity, and occurrence rates. Reliability testing and verification is conducted to verify the reliability of the device and its components, while reliability modeling and prediction uses mathematical models to estimate and predict the reliability of the device. Lastly, reliability improvement and optimization involves implementing corrective actions to enhance the device's reliability while reducing time and cost.
