Power Assisted Fishing Cart

hopworks's Avatar
Greets Everyone! I am not an engineer. I have no college at all. Everything I have learned in the last 52 years of my life have been from.... life. I have one heck of an imagination, but frequently fail at creating anything, at least hardware related, because of my educational limitations. I wanted to throw that out there before I get started, and probably limited my dialog options with present company as a result, but I had to because if I had all that education, I probably would not be posting here from the perspective I am doing it from. And I want the engineering Gods to understand that I swim in layman depths. My wife and I fish a lot. Some from a boat, mostly from a bank on the shore of some beautiful lake in northern Arizona. We haul a great deal of gear to the bank as a result. My wife had suggested that I create and build a fishing cart of some kind. Maybe two wheeled like a hand truck, or maybe four wheeled like a wagon. I went to work using 3D Studio Max and came up with a variety of designs. Some made of PVC, some wood, some aluminum. I came up with some pretty neat designs that would accommodate our needs for a base of fishing operations from the bank of a lake. Needs like pole holders, a large umbrella holder, solar panels for recharging all the USB devices we bring, a small cooler, even battery backup. All the time taking weight into consideration. I think I found a decent balance. But I have never been satisfied with just a basic design, so I decided it might be viable to look at a power assist feature for pulling this thing back up the hill. That is when I was presented with a very large potpourri of technical and mechanical options. And I discovered a wealth of new technology I never knew existed! The closest I could find to what I want is in a bike assist wheel, the "Electro-Wheel" that allows bicyclists the option of getting a powered assist going up hills or just a boost for their commute. It's a fine design and very appealing! But it's $800 per wheel, and the wheels are not exactly what I am looking for. So I am looking for a chain driven solution, which means I need parts for a much smaller wheel, a gear or spoke that drives both wheels on the axle (static on the axle I would imagine), a motor capable of doing the job, and a battery able to sustain at least the brief task of climbing a hill. It doesn't end there though. I will need the motor to stay offline until I pull the cart, then kick in the "assist" but only until no more pull is needed. I am considering many ways to realize the pull, like pulling the cart and have the motor turn without power, generating a signal for an embedded system to realize that it is moving and to apply power until a balance is reached. Maybe, and most likely certainly, with hysteresis in the programming to avoid oscillation. I know, there are many questions to be answered here. I guess the first priority would be to find a solid reliable drive that will power the cart, then deal with the embedded system second. Mechanically, I can envision it but not good enough to build it. Electrically, I am great with embedded systems and code. That part I am sure I can solve easily. The analog electrical I will have to trial and error with. I am so much better at digital. When it comes to analog, and remember, I am not an electrical engineer either, well... ME+ANALOG=FIRE! I study what I have to, to make it work, but I am better at code than wires. The cart can be a simple thing. Lightweight, even made of PVC (for a prototype, I considered it), and not too big. The size of a garden wagon, maybe even a red-rider type lol. If you got to this sentence, you are at least intrigued! THANK YOU! I guess my most needy part of this project would be the wheels, motor, chain drive, sprockets, axle, mounts, etc. Maybe you know of a good simple basic design to build on. Anyway, it's a neat idea and dream my wife and I have. To go along with my PVC-pontoon RC boat I am building with a sonar transducer that feeds fish-finder data to my laptop as it traces along a set GPS path out in the lake in front of where we are fishing off the bank. To offer topographical data about the bottom and possible fish echos. Solar powered, autonomous. Fun to watch while fishing and drinking beer, listening to a baseball game, etc. etc. Let me know your thoughts, tips on where to look for my mechanical needs, ideas, and probably criticism. I appreciate your time! Thank you! Hop - Gary HopWorks - Embedded Imagination

I found some parts that might help my "mechanical" portion of the project. Can't post a link but it is electricscooterparts(dot)com

Hi Gary!

A quick note - we always warn of sharing any details about innovations within these forums as they are public. 

If you're interested in sharing your idea with us to be evaluated for potential licensing opportunities, you're welcome to do so by submitting to one of our innovation searches.

To learn more about our process before submitting your idea, please visit the Edison Nation Help Page.

Best of luck!

As a fisherwoman, this sounds really cool. Schlepping stuff gets old LOL.  Hopefully I will see your product one day in cabellas or REI or another sporting good store In the meantime you might want to check out Edison Nations sister company if you want to pursue this on your own, Enventys.  You can also contact design schools in your area regarding finding a student to assist you (Hopefully under NDA) Please be careful about who and how you disclose your 'invention' publicly.  There are SO Many little innocent things that we can do to trip our own selves up - please get a copy of Roger Browns Book -Common Sense Inventing - its well worth the small investment and will provide worthwhile guidance of 'how to' approach these opportunities.  Best to you.

Hi Gary .. that sounds like quite a project. Most of what you are looking for isn't anything I can be of assistance with. I'll leave that to those who have knowledge in those fields. You may already know this but hunters have some powered as well as manual carts they use to get equipment in and out in rough terrain You might want to check out Honey badger wheel dot com and Little mule electric drive cart to get some ideas for what your wanting to accomplish with the cart portion. Good luck in moving forward.

Gary, all I can say is I hope you can make this happen! As a avid but pysically limited fisherman/woman (lol) I think this idea ROCKS.  Best of luck to you!

Thank you everyone for the advice and support! I figured it was already out there somewhere, but I am a DIY person big time. I am only interested in doing this for us at the moment, but maybe I will find it viable to offer something custom on a small scale if successful. I will post back if and when I am successful, and after reading the suggested materials and taken the proper steps.

THANK YOU EVERYONE! I sincerely appreciate your time!
