Toyota is changing its engineering practices in an effort to halt a slide in vehicle quality. In one major shift, more engineering work will be done in house. The amount of engineering work contracted to outside firms will drop from about 30 percent to 10 percent, according to an article in this morning’s Wall Street Journal. Toyota will also reduce total engineering effort by eliminating engine options and other design variants. In another change, testing time will be stretched out, and possibly will include use of more physical prototypes.
At least some of Toyota’s recent quality problems have been caused by poor fundamental engineering execution. In a problem disclosed by Design News, Toyota says a poorly selected plastic used as friction levers in accelerator pedal assemblies caused the gas pedal to malfunction in certain weather conditions.
Some of the biggest self-assembled building blocks and structures made from engineered DNA have been developed by researchers at Harvard's Wyss Institute. The largest, a hexagonal prism, is one-tenth the size of an average bacterium.
Arevo Labs' end-production 3D printing technology for carbon composites includes a high-temperature, filament fusion printer head design and firmware for use with the company's new carbon fiber and nanotube reinforced high-temperature matrix polymers like PEEK.
Stratasys will buy Solid Concepts and Harvest Technologies and combine them with its RedEye service business. The plan takes aim at end-production manufacturing and will create one of the biggest commercial 3D printing and AM service bureaus.
The International Federation of Robotics reports that global sales of industrial robots decreased by 4% in 2012 over 2011. The biggest hit was electrical/electronics manufacturing, down by 13%; but by region, the Amerficas did well.
