My Dad invented the filler cap for the coolant reservoir on the Ford Raptor.
Because the Raptor sees off road use Ford was having a problem keeping the coolant from ending up all over the engine bay. They came to Dad and within weeks he had a working prototype. Just today he was awarded the patents for his solution. Because he works for a corporation he gets his name on the actual patents but the company owns the rights. That’s just how it goes.
Below is his description of his solution:

The Raptor had a non pressurized overflow coolant bottle. When the coolant system expanded, the coolant goes thru the radiator cap, thru hose, to storage bottle. When the system cools down, it sucks the overflow coolant back into the system. Non- pressurized system reservoirs need vent holes to let the air out & in during the expansion / contraction process.

Normal street vehicles don’t see the bouncing & violent activities off road sees. During off road activity in the Raptor, the coolant in the overflow bottle sloshing around would squirt out of the vent holes ( 3 vent holes in this cap ).

This cone was inverted to snap into the existing cap. We just had to modify the cap for 2 holes that the cone could snap into. ( The slot was already in the cap )

There you have it. A little peek at part of the automotive industry. I will have more as my Dad also did the coolant bottle for the Wrangler and Dodge Nitro among many other vehicles. He is currently working on windshield washer bottles and has even made combination bottles and semi bottles.

I hope everyone enjoyed my first post. Thank you for reading.

  • Very cool! My dad works for a startup 3D printing company, and has been able to work closely with McLaren and SpaceX.

    • Wow!! You need to be careful what you say about that stuff. Speak with your father before you go any further than what you have. I am NOT kidding Will. But then post everything you CAN say. Just set off a legal shit storm.

  • Really cool to see all the thought that goes into engineering a car. Really weird to think that they have engineers who are dedicated to filler caps. Super cool though!

    • I have gotten see behind the scenes my Dad’s entire career so I will be sharing more.

      And yes each part on every single car is engineered. Stacks of legal red tape for each part. It is truly astounding. There is a reason cars cost so much and...

  • My grandfather did the same thing, working for a corporation- his name is listed as inventor but owned nothing. Coin operated mechanism, dollar bill changer, electric eye, big rotary dial they used to use to dispense greenstamps.

    • That’s the deal. But here’s the thing, it costs roughly $7k to get a patent. That does not include legal fees if anyone contests it. It does not include R&D. It does not include prototypes. It does include production or marketing. It is merely...

    • I made an invention. I prototyped it. I built it full scale. I then built it in steel, then aluminum. I did the technical drawings, I adjusted them, and my final working model, several times. I had everything ready for a patent attorney to...

  • Awesome write up! And a doubly awesome solution to an interesting problem. It’ll be useful in a whole range of high-performance situations. My dad once engineered a side mirror repair from duct tape but that’s the best we did. No patent for him or the “company,” but we kept him on as “father” nonetheless.
