i wonder if it was chinese's brand or chinese design to cause such a unsafe & life threatenin OR it ...
Well, since you ask, I bought them from HK.
Funny thing was, there were a few different sellers, selling stuff from different makers.
Being el scungy at the time, I got the el cheapo ones. I saved a massive 5 cents each.
About half a Yuan or 5 Jiao.
How could they make and insert and extra component (the spring) for less money than the other ones?
I don't know?
I think the way for all electrical connector manufacturers to go, is to never, ever intentionally design something that can be a dead short into any electrical connector. It's a fire waiting to happen.
You know, if it can go wrong, it will, because people are also involved.
Regardless of where it was made.
I reckon it was a new manufacturer with a just out of uni design team and it was their first go at re-inveting the wheel.
Now, about just out of uni design teams.
Years ago, in Australia, a just out of uni, lets re-invent the wheel team went to Western Australia to help make the railways much better than they were.
They re-designed the system of spikes and retainers for the track to the sleepers.
After they had tested them? They were fitted and of course, soon failed, and all need to be put back the way they were before.
Shit like this happens in every country.
These are they failed attempts at advancement.
If we didn't keep trying, we would still be throwing rocks at each other instead of talking nicely on an internet forum.
What went wrong at the connector factory.
I wasn't there to tell them what would happen if they put a spring into it.
Impossible to actually know, not being in touch with that design team and their assumptions about specifications.
Very bad that people got hurt with this stuff.
There is however missing information from the story.
Were the people that hurt themselves,
hurt by the chair, or themselves.
Were the chairs designed for a medium to light max body weight and did they end up with a 200kg crusher sitting on them. (We all know what a non-thinking person is capable of)
This forum has a million posts about them.
