I was walking down the street the other day, saw a semi truck, and bam, I had this idea. I scurried home and sketched this. I was immediately sure it would work and that there was a need for it. I had never seen this system before on a semi truck or trailer.. perhaps the need is not overwhelming, but in certain cases, it is an excellent solution. To apply the tracks, you lay out the tracks, back over them, wrap around the dual wheels, and bolt/pin them. (and tighten)

I knew that I had a reference after watching a few episodes of "Licence To Drill" which details the mayhem of drilling for oil in the Canadian north, and especially watching tractor-trailers with heavy loads, hauling in the mud. I thought the idea had been cooking in my subconscious.. and poof. you know how it goes.
I did some searching around on the web, but didn't find any specific references... so I took some time to model it up. (very happy with the results. I used someone else's truck model and just added the tracks.

but after it was all done, I started looking around more.. only to discover that it has been done.. and very similar as I had imagined.. serving the oil industry in the muddy and snow bound northern Canada.

so I'm wondering how do I get to some really original ideas. I know there is a saying "There is nothing new under the sun" but that clearly has some fallacy to it. otherwise we would not be continuously evolving our technologies.
Has this sort of thing ever happened to you? I give thanks for Google and other search engines that I am able to let go of this one quickly, without investing more than a couple of hours in it.
