Fool-safe, also sometimes spelled "failsafe," describes a design or system engineered to prevent accidents, errors, or malfunctions caused by human error. It implies an intuitive, user-friendly approach that minimizes the potential for incorrect operation. The intention is to be easily and safely used by anyone, regardless of experience or skill, with minimal risk of causing damage, harm, or unintended consequences. The core principle emphasizes minimizing the likelihood of mistakes through robust design and inherent protection mechanisms. It's a design philosophy where potential human failings are anticipated and accommodated, making the system or device exceptionally reliable and secure in its operation.
Fool-safe meaning with examples
- The new software's user interface was designed to be fool-safe, with clear instructions and prominent warnings to prevent accidental data deletion. Even a novice user could navigate the system without fear of causing a major error. The developers prioritized simplicity and clarity, ensuring that even careless inputs would be processed without catastrophic results.
- The car manufacturer equipped their vehicles with a fool-safe braking system that would automatically engage if a collision was imminent, even if the driver failed to react quickly enough. This added layer of safety reduced accident risk by compensating for human error. Numerous sensors and fail-safes helped ensure a smooth and controlled stop.
- The laboratory adopted fool-safe protocols for handling hazardous chemicals, including color-coded containers, spill containment measures, and automatic shutdown systems in the event of a leak or fire. These measures greatly minimized the risk of exposure and reduced the potential for accidental harm. Strict regulations ensure complete safety.
- The design of the ATM included fool-safe features such as automatic card retrieval if the user forgot to take it and multiple attempts to enter a correct pin. The system was protected from external attacks and internal errors. This protects the customer by reducing potential losses and the chance of getting locked out.
