I don't know how hard the author was hit, or how he was hit, but it's interesting to note that minivans (such as the Odyssey) didn't have large sliding doors on the driver's side for many years because they couldn't provide sufficient torsional stiffness when they had big door openings on both sides (remember how minivans only had one sliding door a few years back?). Sounds like all that FEA work on the Odyssey's space frame did its job.
Appliance repair men work in modules. They will generally only replace defective FRUs. We had a problem with one a while ago. It was in a double oven. The repair guy told us that the module was no longer manufactured, so he could not fix it. He suggested replacing the oven. Oh, by the way, the new ones were slightly different in size (same manufacturer, mind you).
Well, I isolated the problem to a component, which would need to be replaced. I decided to have the module repaired when we found that there were places that did that. One of them was near by, so I took it in rather than shipping it. It works fine now. For about $150 I avoided a purchase of over $2,000. It pays to fix, rather than to replace.
Come to think of it, your opening line was, ",,,hit in the driver-side door". I would speculate that the body shop may have opted for a non-factory-authorized replacement module after the factory window module was destroyed.
Like Mr. Goodwrench always used to say, "Insist on Genuine {GM} Parts". Third –party component manufactures have no responsibility for the overall quality of an electrical system, because they have "no skin in the game", so to speak. They are trying only to peddle after-market modules.
I've spent half a lifetime examining mother boards and solder joints under a microscope and have often found things that make me wonder where the QA process is at many world-class companies.Your example of solder bridging is likely root caused as too much solder on the connector joints, and further root caused to poor stencil & pad design at the PCB layout stage.
If you're familiar with high volume manufacturing of electronics, you know that each electrical component, (in this case, switches) comes from it's manufacture with a recommended PCB hole pattern, or a recommended solder-pad layout if an SMD device. Its up to the PCB designer to follow the recommendation, or the "fault" can be pointed to the switch manufacture for bad solder joint design. In the case of Honda, its surprising that solder bridging is occurring on a world class car like an Odyssey.
I'm curious, too, about the origin of the solder bridge. It sounds like something that either was there to start with in the factory--but then shouldn't it have caused this problem a lot sooner?--or that it occurred at the body shop during the door's post-accident repair.
Was the solder bridge a result of the impact or was it a glitch that occurred unrelated to the accident? I have to applaud your detective work. I wish the larger pool of appliance repair men/women and mechanics had similar tenacity to stay on a problem!
For 3D printing to make the jump from rapid prototyping to manufacturing, engineers will need to find easier ways to move products from their CAD screens to their printers.
Gigabit and PoE are two networking technologies moving ahead in tandem as industrial users power remote Ethernet devices such as IP security cameras at 1,000 Mbps over existing CAT5 cable.
New versions of BASF's Ecovio line are both compostable and designed for either injection molding or thermoforming. These combinations are becoming more common for the single-use bioplastics used in food service and food packaging applications, but are still not widely available.

For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This radio show will show what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
