Greg,

Thanks for the feedback.  Hopefully as you integrate DfD in your design process, you'll find that assembly and serviceability of your products are both positively impacted as well.

Design for Disassembly Guidelines

Thanks for the 8-Step DfD guidelines. In addition to designing for assembly, I need to keep these tips displayed in front of me to prompt me to consider design for disassembly also.

The problems with used electric vehicles, hybrid and others.

What will be the very most interesting is to see how the aftermarket plays out in 5the EV battery area. I can easily see a possiblity that the battery packs will have an electronic serial number and manufacturers code and that the vehicle could be easily set up to not run without an OEM battery. That would assure a captive market for replacement battery packs, no matter how much they cost. So it would be quite prudent for a law preventing that sort of thing to be put in place prior to the problem becoming a big issue. Already we have computers and cell phones that won't function with other than OEM batteries, which happen to cost a lot more. How vwery convenient.

So purchasing a used EV will be an interesting excersize, possibly in frustration. That is my guess.

Rob,

I'm not sure that the automotive industry itself was ahead of the curve.  Excluding the used car market which for the purposes of design for disassembly can be viewed as an extension of the primary life of the product (same product use, different owner), it was parties outside of the Big Three that saw the opportunity and value of the car corpses.  That vision took the form of reselling the used components, sub-assemblies or scrap metal and made that re-use/recycle stream a reality.  Having worked in product engineering for GM for 5 years, I know that product "afterlife" was rarely given any consideration even when it was cost-neutral to do so.

The auto industry has gotten better in recent years, but that improvement hasn't really originated within the automotive industry - it has mostly been driven by European governmental policy which emphasizes corporate responsibility for product afterlife. 

 If I had to pick one point in time that seemed to have catalyzed the current trend of design for disassembly, I'd probably pick the investigative reports and documentation of the dumping of PCs and electronic peripherals in Third World countries and the major environmental poisoning resulting from it.  For some reason, those stories had legs in both the media and around the "water coolers".

Good point, Rob. For some reason, the auto industry has yet to give much thought to the recyclability of lithium-ion EV batteries. The best guess I've heard is that we know it's about 80% recyclable. Beyond that, there's not much agreement on what to do with it.

Good point, Rob.  With a standard ICE car, you know what to do when it gets old.  You can replace the engine and transmission with a new or rebuilt one.  You can put in a new gas tank.  Upgrade the radio.  Rework the suspension.  You can add decades of life to a standard car.  But what do you do with an old hybrid?  We don't know, yet.  But it ain't that easy or straightforward, I bet.

Auto industry afterlife
Rob Spiegel   5/16/2013 11:30:14 AM

The automotive industry has long been head of the curve on the afterlife of its products. Even after a vehicle has been passed from owner to owner, the system of handling scrap cars is well developed. That is until electrical vehicles. The value of a used EV -- even a hybrid -- may be compromised by the cost of a replacement battery. Car buyers could long depend on the resale value of their existing car as they evaluated the worth of a vehicle. This is not clear with EVs and hybrids. It will be interesting to see how this plays out over coming years.

Sharon Glotzer and David Pine are hoping to create the first liquid hard drive with liquid nanoparticles that can store 1TB per teaspoon. They aren't the first to find potential data stores, as Harvard researchers have stored 700 TB inside a gram of DNA.
If you see a hitchhiker along the road in Canada this summer, it may not be human. That’s because a robot is thumbing its way across our neighbor to the north as part of a collaborative research project by several Canadian universities.
SpaceX has 3D printed and successfully hot-fired a SuperDraco engine chamber made of Inconel, a high-performance superalloy, using direct metal laser sintering (DMLS). The company's first 3D-printed rocket engine part, a main oxidizer valve body for the Falcon 9 rocket, launched in January and is now qualified on all Falcon 9 flights.
Stanford University researchers have found a way to realize what’s been called the “Holy Grail” of battery-design research -- designing a pure lithium anode for lithium-based batteries. The design has great potential to provide unprecedented efficiency and performance in lithium-based batteries that could substantially drive down the cost of electric vehicles and solve the charging problems associated with smartphones.
UK researchers have come up with a method for machining aerospace-grade, carbon fiber-reinforced composites, along with high-strength aerospace alloys, using an ultrasonically assisted machining device. It also works on high-strength aerospace alloys.
