Tool_maker, I agree. If we accept garbage products then that's what they will sell. The cheaper they can make them the better for them. A 2 cent part might make the difference in a good or bad product, but they don't care. My mom does it all the time....she sees something for cheap...buys it, then wonders why it breaks days later. I doubt there is a solution to this.
It quit working a few days later so you set it aside until you could work on it. Did you write a letter to the manufacturer? Probably not. So the bean counter who chose profit over quality has won. If everyone who bought one of these inferior products took them back to the retailer soon they would disappear from inventory and would end up in Big Lots or Dollar Tree store until the supply was exhausted.
I keep repeating the same mantra: If we accept garbage any CEO who is doing right by the stockholders will maximize profits by producing and selling the cheapest product he can. When the item was bought and kept, even though it was of poor quality. you confirmed that attitude. In the future, I hope you take deffective items back and demand a refund.
We use a pepper grinder that we inherited from my mother in law. It has been used regularly for at least four decades. It works great. If I tried to take it apart to analyze its superior performance, my wife would kill me.
Last year, we received as a gift a very nice looking pepper grinder that did not work out of the box. It looked good, had the screw top adjustment for grind, and either gave out nothing or locked up on the first few tries. On the next turn, the mechanism kind of just fell out of the top of the grinder. It went in the trash. We went back to old reliable and use it daily.
I suspect we might have picked it up at Sur La Table in Walnut Creek...
It's plastic, and it's a combo Salt Grinder/Pepper Grinder. It has two levers at the top that you squeeze to dispense. It has a little S in the window on the side when it's grinding Salt, and a P in the window when grinding pepper. You just rotate the levers around to change it.
My wife has Rheumatoid Arthritis, and she has very little hand strength. Most rotary grinders are too difficult for her to use. She has trouble unscrewing the cap off a bottled water.
The levers are very easy to use, and it dispenses from the bottom. We've had the thing for years, and it's still working like new... I've refilled it several times now, and it's been a really great little addition. The wife has been having me put Sea Salt in it... She thinks it tastes better, although the only real difference that I can see is it doesn't have iodide added to it... (We get plenty of salt with iodide, in any case...)
The pepper bottles with their own grinders I've seen have a pressed on cap in order to discourage re-filling. For a "throw away" item, they supply a fairly good grinder. Now any one clever enough should be able to pull the cap off in order to refill. Just be careful you don't break the glass bottle, gash a finger severing a tendon, and end up with a $ 10K hospital bill. Risk versus reward study anyone?
Good engineers make wrong assumptions all the time. Your last three posts in quick succession, 4 sentences total, certainly suggests an impulsiveness on your part, (No edit buttons?) not to mention a willingness to make an assumption about the author, and anyone else.
The author wasn't really concerned about the grinding surfaces, nor did he say anything that suggested he even looked closely at them. No brand name even, so I couldn't look it up. If he's wrong, no big. If I'm wrong, no big. If you're wrong, well, probably someone elses fault, right?
A new service lets engineers and orthopedic surgeons design and 3D print highly accurate, patient-specific, orthopedic medical implants made of metal -- without owning a 3D printer. Using free, downloadable software, users can import ASCII and binary .STL files, design the implant, and send an encrypted design file to a third-party manufacturer.
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.
