Even when an owner can open a smoke/CO detector, getting to it can pose a problem. I have vaulted ceilings, so to change batteries I must bring in an extension ladder and move it from room to room to get to the battery compartment. It beats me why some company hasn't figured out how to create a battery cartridge that could go into a detector and latch in place. Pushing on the cartridge would eject it. A long pole similar to the one I use to replace light bulbs would do the trick. Think how a retractable ball-point pen works and you'll get the idea. It sure would save time and energy.
Naperlou, I agree. We have seen that happen as well – for multiple reasons, often cost or availability related. There may also be engineers at the other end who simply disagree with the initial design...or perhaps they have an overstock on one type of connector when the initial design calls for another...
"What ever happened to design for manufacturing where the engineering team was colocated with manufacturing???"
While that would be ideal, I believe it is simply a matter of driving down the cost by manufacturing in other countries, but companies still want to maintain control of the design inhouse. One company I worked for, I worked in R&D where we developed the test sets that would be used to test the products manufactured in our plant in another country. A LOT of money and time was devoted to our test engineering staff travelling back and forth to initially set up the test sets and then to maintain them. Finally, our department was transferred to that country which made better sense and was more cost effective for our company. Unfortunately, it also eliminated the need for my job...
There are no easy answers, what works well for one company may not work well at all for another, depending on cost, staffing and industry contacts just as much as anything else. Yet another challenge of our global economy that continues to be a mixed blessing.
Larry, I know that customer returns mean lost revenue. But then, lots of practices mean lost revenue and I see lots of companies keep doing the same things that lose them revenue, many of which we've covered here at DN. What I meant was that most big-box stores I've complained to about crummy product quality--like this one--don't care and keep selling the same crummy products. And I've had the same experience with the manufacturers of the same crummy products, even when they get lots of returns. I'm glad your experience seems to be different. But I wouldn't hold my breath assuming that the monitor manufacturer will even notice that the covers are stuck on. In my experience, if the product can be sold at a big-box store and costs less than $100, there's little motivation to change much.
Nancy, you post bring to mind a disturbing trend I have run into consulting over the last few years. Many of the products made off-shore are not made to the design. Changes are made in manufacturing without telling the "customer". My experience was with small companies so I assumed that the problem was that these small companies just didn't have the resources to do the proper quality control. I was telling a friend of mine who worked for a large company about a particular example in the industry he was in. He related that his competitor, another very large company ran into exactly the same problem. The only difference is that the large company had the resources to correct the problem. The small company I was consulting with did not.

Mr. Muren is partially wrong about the California requirement. All homes are not required to have working carbon monoxide detectors. A detector is not required if there is no natural gas, propane, butane etc., service. We have a rented-out condominium in San Diego that is "all electric". I had a hard time convincing the property manager, to not spend several hundred dollars & have a c-m detector installed.
I agree TJ - and it is definitely a valid point. Poor design is poor design, wherever it takes place. My husband and I designed a product for the company he works for and they manufactured it in China. Any design flaws if they exist are our responsibility - not China's. I was simply suggesting another possibility as to why what happened could have happened...it is almost more plausible to me that a designer was given a project that he did not understand properly because he had no prior experience with the product, then for such a blatant design flaw to occur in the U.S. where these products are common. I could certainly be wrong, it was just a thought...

In a bid to boost the viability of lithium-based electric car batteries, a team at Lawrence Berkeley National Laboratory has developed a chemistry that could possibly double an EV’s driving range while cutting its battery cost in half.
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 discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
