Heavy-duty industrial carts use polymer-covered wheels to reduce noise and
limit damage to floors. The Omega Wheel line of heavy-duty casters goes further,
with a patented cast-spoke design that permits it to deform locally when
encountering irregularities or debris on floors then return to its regular shape
once the obstacle has been cleared. In combination with a proprietary blend of
low-thermal-conductivity polyurethane, the open-spoke design runs cooler than
solid wheels, lessening the chance of debonding of wheel and hub.
Polyurethane's resilience results in a quieter wheel less apt to tear or pick up debris. In many cases, this unit allows users to switch from a spring-mounted caster to a simply supported design. Supplied as complete casters with patented kingpin-less construction or as easily retrofitted wheels, Omega Wheels are available in a range of capacities and sizes.
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.
