Bathtub Curve Explained: Why Engineering Products Fail (Real Industry Examples)
Why do products fail — and why does it happen in predictable stages?
In this video, we explain the Bathtub Hazard Rate Curve using real engineering failures and industry examples.
In 2013, Samsung recalled over two million washing machines due to catastrophic failures. These failures weren’t random — they followed a well-known reliability pattern every engineer must understand: the Bathtub Curve.
This video breaks down the Bathtub Hazard Rate Curve in simple, practical terms:
• Burn-In Region (Infant Mortality)
• Useful Life Region (Random Failures)
• Wear-Out Region (Aging & Degradation)
You’ll learn:
✔ Why new products fail more often than expected
✔ How engineers predict failures using hazard rates
✔ How Boeing, automakers, and data centers plan maintenance
✔ Why ignoring wear-out leads to recalls, downtime, and safety risks
This is essential knowledge for:
• Mechanical Engineers
• Electrical & Electronics Engineers
• Reliability Engineers
• Maintenance & Operations Engineers
• Engineering Students
If you want to design products that last — this concept is non-negotiable.
