That seems like a compelling case for a different design - doing something so that the existing motors can be used. Hopefully when all this blows over we'll have some interesting books and articles to read!
Well, both require lots of high grade flexible plastic tubing and benefit from things like HEPA filters. The only difference is the motor -- but Dyson also manufacture low-power fans en masse, so they've got many different breeds of motors in stock.
Agreed. As I understand it, Dyson’s ventilators are ready for scaled production. Maybe they can begin to collaborate with others down the road, but time was essential, and they were clearly able to get these out without a lot of unnecessary phone tag.
I know what you're saying, but in this instance there's a fairly good technology & manufacturing fit between ventilators and Dyson's other products. More so than some car manufacturers.
Dyson's core business and knowledge involves small devices which move and filter air, often on battery power (yes, I'm simplifying!). So designing something that reuses their existing technology with minimal retooling of the factory might well be easier and quicker than adapting their factory to an existing design.
From what I understand, Dyson is not trying to "design a perfect ventilator." He's trying to design a cheaper, easier-to-produce ventilator that will be good enough for many situations, vastly improving the availability of ventilators for all who need it.
Everyone else seems to be just working on producing the existing, hard-to-produce ventilator.
One thing I particularly fell in love about the Dyson vacuum (DC29) we bought about 5 years ago was how easily serviced it was. We burned out a motor and everything about the machine was designed for simple manufacture and serviceability. There weren't random cables and screws going every which way. Following a servicemans YouTube, everything clicked apart and back together again. The plastic tooling was very precise. I imagine using those principles for medical apparatus will help in manufacturing consistency, ability to clean and service. They might even find themselves a whole new business path after this. (I'm expecting Elon's similar foray will have equal opportunity for innovation - though I have never been in the position to pull apart a Tesla!)
There is a separate, co-operative effort by a consortium of manufacturers to improve and mass produce an existing ventilator design.
But with a project of this importance, while it makes sense to pool resources, you can't realistically have every company and every engineer co-operating on the same project. So it also makes sense to have several, independent efforts running in parallel.
This does make sense. Every company that normally doesn't produce ventilators but wants to make lots of them fast must repurpose as much of its existing tech (production lines, parts etc.) as possible. This requires intimate knowledge of private tech, which only internal teams have.
The government turned down an offer from the EU because Europe which is a bit worrying.
There are plenty of medical equipment manufacturers in the UK who've made these exact products before, or very similar products, and who know the rules and regulations well. They've offered to help, but not heard anything back from the government.

You're extrapolating a lot here. That's one guy showing up on TV, presumably running a small medical equipment company, who got into contact with someone at the DTI, who told him to fill out a form on a website. He did, but there was no followup. The end.
Note that he also says he can't actually ramp up production that quickly, that he relies on subcontractors that aren't available, and so on. I don't see what the government can actually do for him, besides ordering something that he can't produce at bigger capacity anyway.
A company like Dyson could presumably produce the whole thing in-house. A zoo of interdependent companies may be more efficient at small scales, but at large scales, logistics becomes the bottleneck.
Yes, but those 8000 orders are piecemeal from any supplier that has any kind of stock, a few hundred here, a few dozen there. There's not a coordinated drive to support those manfs to increase their production.
As you say, the Dyson effort was a separate programme. Existing medical equipment manufacturers -companies that make medical equipment but not necessarily these ventilators at the moment- tried to apply to that separate scheme and they were ignored. The money went to Dyson or car makers. It's probably better to spend the money on companies that already make medical products and help them increase their capacity than it is to spend it on car makers and Dyson who'll need to re-tool their factories and re-train their staff.
Whatever his views on Brexit (and I am Remainer), I think credit should be given to Dyson and his team - they are going to be manufactured in the UK and he is paying with his own money for 4000 of these ventilators to be donated to other countries:
He moved his head office to Singapore around the time he was pushing the UK to leave the EU. Manufacturing had already been moved offshore years before that - Malaysia as I recall, though probably elsewhere too.
Here is the very high level specification that the government has provided. It refers to various further specifications and regulations that the device must comply with in order to be accepted by medics.
So are ventilators actually complicated and frequently modernized equipment or medical TI83s. I was reading one the largest expenditures of PPEs in China after they resolved the supply issue was adjusting ventilator settings. Seems like a wired or wireless interface would go a long way.
