What Makes Design Successful?

What makes an engineering design successful? It isn’t just solving technical challenges. The device needs to serve the end user. Subaru designed a simple car that met the needs of a generation. A recently developed fire starter is high tech, but is more expensive than a match and requires infrastructure. There are inherent advantages to using ultrasound to dry clothes instead of hot air, but technical challenges remain. In the end, which design will be deemed most successful? Happy reading.

Ultra-efficient Ultrasound Takes the Heat Out of Clothes-drying

Fire Up Charcoal Starter Wand

So what would an engineer with an interest in low-tech, old-school charcoal barbecues create? How about a starter that, while technically superior to a match, costs several orders of magnitude more and requires you to have a source of 120V AC electricity?
