Fail-safe design

Definition

Fail-safe design is an engineering approach that ensures systems remain safe and functional even when a failure occurs. This concept is crucial in applications where safety is paramount, as it focuses on minimizing risks by allowing systems to default to a safe state during malfunctions or unexpected failures. The goal of fail-safe design is to protect both the system and its environment, which is especially important in high-stakes fields such as underwater robotics where battery technologies play a vital role in reliability and safety.
