I think you can see that this is an area where there is lots of prior art and products in the market place. We now need to narrow our area of focus. Let's go back to mackgadget's earlier post:

I am thinking of ideas for feeding, watering, bathing, grooming, litter boxes, pooper scoopers etc. Also ways to keep pets off furniture etc. as well as the doggie door.


Let's go with the doggie door for a while but expand it a bit to include cats. Try a search argument like: pet door cat dog and let's just stick with:

for now. Have you tried that? Google Patents does not allow us to select the patent Abstract or Specification only. So let's go to:
and enter the search argument to search the Abstract of the patent database only. The search argument (just copy and paste) will be:
    ABST/pet and ABST/door and ABST/cat and ABST/dog
Now while you are there, change the search argument to search only the Specification:
    SPEC/pet and SPEC/door and SPEC/cat and SPEC/dog

The Title and the Abstract are where you want to search first, and then the Specification. Play with that for a while and see if ideas are forthcoming.

There is also a Quick search interface at the USPTO database if you prefer to use it:

Keep in mind while you are searching, the objective is to achieve the fewest number of hits while not artificially eliminating hits.

As you generate ideas, go and try them at the other places (ThomasNet and Google).

Are you having any luck?

I see many solutions that selectively let certain pets exit and enter, but none, thus far, that solves the problem of a cat TAILGATING behind the dog as mackgadget stated:
    if the dog stops outside the door after going thorugh, the cat can go through


I think this has potential! Just not sure how to accomplish it. I'm gonna go search some more and think about it!

OK, I have an idea! It has its drawbacks, but at leasts it has the juices flowing.

Both the dog and the cat have Radio-frequency identification (RFID) tags on their collar. There is a vestibule (a rectangular box) with an entry and exit flap/door on each end. It the dog enters the vestibule (from the inside or outside) and the cat is not in the vestibule, the door closes behind the dog and the opposite flap/door opens so the dog can exit. If both the cat and the dog are in the vestibule, the entry flap/door remains open and the exit flap/door remains closed until only the dog is in the vestibule.

Expensive? Yes!

Your thoughts?

I don't know what you are doing offline, but that is OK. Are you coming up with ideas? Does anyone have an idea they would like for us to take forward in How to Finance Your Invention?

If so, and you want to produce and sell it, you are pretty much on your own. You need to write a Business Plan and find investors, unless you can handle the financing on your own.

If you want to license your idea/invention, we can help you a little more here before you are left on your own. We will need to know the area of your idea/invention and just enough more to help you locate a manufacturer.

Trickss

I keep thinking that there must be a mechanical way. Dogs are easier trained than cats. I think most of us would agree on that. A dog can be taught to lift something or pull something that might lock behind him until he comes back and does it again. It can't be too complicated since not everyone has the patience to teach a dog to do tricks. I have noticed that my dogs go through the door nose first and actually push the door with their nose. The cats do not. They first hit the door with their paw and when it bounces open a tad, then they go through. Mack :arrow:

I am struggling with ways to make this mechanical. I have the following questions:
    How would you know whether it is the dog or cat at the door?

    Are all breeds of dogs easily trained to perform whatever is required?

    How would you prevent the cat from tailgating behind the dog?

I, obviously, do not know dogs and cats like you do. So, be patient and help me along here.

First off there are some breeds that are smarter than others. That being said I have trained many breeds and mix breeds to sit, stay, heel, lay, roll over, play dead, jump up or down, jump over, and catch. Things like that. Problem is this can't be too difficult or people would not all be interested in doing the training. As for the question of how to know whether it is the dog or cat at the door is not important. A dog could pull a rope with his mouth or be taught rather quickly to step on something but a cat would not catch on to that.
The cat would never tailgate the dog out. They are by nature skittish and when the door closes it makes them flinch and sometimes run. However later they will come back and push at the door with their foot out of curiosity and sneak out. I have trained our cats to stay off the table and counters by proping up a couple of plastic plates with pencils on the table and counter when they jump up and jar or touch the plate it falls over and scares them. A couple of times of that and they avoid that area. A banging or snaping noise when the door starts to open might work. Most dogs can be easily taught to ignore that. It would even be a nice thing for the people because they would know that the dog went out or in. This is not the perfect answer because there are some timid dogs. :arrow: Mack

As bad as it seems MARIJUANA! yes. ive had a few great idea while i was high. ive also had some horrible ideas that made no sense the next day when i woke up. But i honestly think smoking weed can put a new idea into your mind that you would have never imagined.
