Planetary Telescopic Bicycle Kickstand

Concept design

For the past 14 years, I've been developing intermittently a unique design for a bicycle kickstand, known as the Planetary kickstand concept showing is the Telescopic model. This innovative design integrates telescopic functionality with planetary gear mechanics to provide a robust solution for bicycle stability. Grok gives a detailed overview of this new concept:

Enjoy.
Your design has a driveshaft, a planetary gear, and a bevel gear in it, I guess. It will cost over 50 USD to make that.

Note that today, common bicycle kick-stands can be manufactured for <10 USD (2020 currency) per unit, and have been made ever since the 1960's. There are only 5 or 6 parts in them and the design hasn't evolved much AFAIK in 50 years. To some that looks like an opportunity to build a better mousetrap. To others, like me, this mousetrap looks pretty hard to improve upon.
 
Definitely a neat idea, a kickstand that retracts some length when raised is definitely a "would be nice." However, in all my years riding bikes, the kickstand being too long and catching on something or accidentally deploying has only happened maybe 10 times, and could be fixed with a kick while riding. Unless this design is solving some other big problems I just don't see the point.

This thing looks way too complex to fix-on-the-go, which is one of the greatest aspects of the modern bicycle (even kids can fix a bike).

Plus, a "common" kickstand can be weighed in grams. How much would this thing weigh? Bikes should be light.

What happens when it rains or I drop the bike in mud? The deign looks pretty contained, but a telescope is never going to be a perfect seal. What if water enters there, or rock chips get embedded within the helix of the recoil spring?

This system features a windup mechanism using hollow tubes, so I don't believe weight will be an issue. However, a much simpler model will also be available, and future designs might include a ring gear mount, then motorcycles where weight is less of a concern.

I believe you're referring to a misfire. In the down position, the telescopic tube can be manually pulled into its locked position. Similarly, in the up position, the telescopic tube can be pushed into its loaded position, much like loading a dart gun.
 
Looks like a solution looking for a problem. The conventional solution has low cost and simplicity going for it, so this approach is a non-starter for me. Not to mention that you posted in a forum with no obvious connection to the problem, or solution
 
Wow, 14 years? I have been an avid cyclist for 55 years and as IRstuff says, looks like a solution looking for a problem.
I don't think any of my current bicycles even have kickstands although all of my motorcycles do.
Maybe there is a market there?
