Engineering Simplicity or Complexity

Complicated, intensive engineering may result in an efficient, simple design. Blowing air to control flight instead of using mechanical linkages, and using shrinkage to form a complex shape instead of forceful coercion are elegant solutions. Modern products are typically made more complex, though, with more instrumentation potentially making operation or maintenance more efficient. We need to be careful not just to trade off that efficiency for less self-reliance. Data should increase our understanding, not decrease it. Happy reading.

New Aircraft Hopes to Boost Safety with Flapless Design

New Aircraft Hopes to Boost Safety with Flapless Design

"Whenever you are dealing with mechanical systems, the most frequent points of failure are in moving parts under stress." To increase reliability, BAE Systems has designed a new flight control system based on supersonically blown air. Taking a step back from the details to review the fundamentals has spurred innovation.

How Condition Monitoring Led the Way to Industry 4.0

How Condition Monitoring Led the Way to Industry 4.0

What were Industries 1, 2 and 3 again? Real-time vibration monitoring can make maintenance more efficient. However, even with machine learning, interpretation of data is needed to reveal root causes and prescribe appropriate actions. Engineers are still needed in the loop.

Who Has a Right to Repair Your Farm or Medical Tools?

Who Has a Right to Repair Your Farm or Medical Tools?

As software is more tightly integrated into machines such as tractors, it is possible for a manufacturer like John Deere to make its products perform worse over time, like Apple is alleged to have done. Requiring the manufacturer to make any repairs means waiting on its schedule. Should the owner have the right to read the machine's diagnostic data and make repairs instead?

Urbach Tower Pioneers

Urbach Tower Pioneers "Self-Shaping" Wood Construction Technique

This wood tower was designed to circumnavigate energy-intensive bending techniques. The complicated design calling for intentional shrinkage used computer simulations to predict the twist of components as they dried. In the end, the components were assembled in one day without scaffolding or framework.
