Two years ago, I was warned by a friend that if I went with a Delta faucet, it would fall apart. I did not heed that advice because I liked Delta pull-out faucet model 474 NN (NN designates brushed nickel). Indeed, two years later, threads in the soft plastic that holds the aerator in the spout stripped. To its credit, Delta customer service shipped a new spout free of charge the day after I filled out a simple e-mail form describing the problem. In checking on the order , a cheery and competent customer service rep came on the line and confirmed the shipment. I was impressed.
But it made me wonder what type of plastic was used in the spout. What were engineering and cost tradeoffs made in deciding what plastic to use? I'm mechancial enough to screw in an aerator without mauling the threads, but I thought this plastic was unusually soft. After all, anyone is going to clean the aerator from time to time and that means removing it. So I my call is into Delta. Stay tuned for explanation or offer your if you have one.
During a teardown of the iPad Air and Microsoft Surface Pro 3 at the Medical Design & Manufacturing Show in Schaumburg, Ill., an engineer showed this "inflammatory" video about the dangers of maliciously mishandling lithium-ion batteries.
Science fiction author Isaac Asimov may have the best rules for effective brainstorming and creativity. His never-before-published essay, "On Creativity," recently made it to the Web pages of MIT Technology Review.
Much has been made over the potentially dangerous flammability of lithium-ion batteries after major companies like Boeing, Sony, and Tesla have grappled with well-publicized battery fires. Researchers at Stanford University may have come up with a solution to this problem with a smart sensor for lithium-ion batteries that provides a warning if the battery is about to overheat or catch fire.
In this new Design News feature, "How it Works," we’re starting off by examining the inner workings of the electronic cigarette. While e-cigarettes seemed like a gimmick just two or three years ago, they’re catching fire -- so to speak. Sales topped $1 billion last year and are set to hit $10 billion by 2017. Cigarette companies are fighting back by buying up e-cigarette manufacturers.
