Shimano Patent Filing Raises Electric Questions

Feb 13, 2018

Shimano Patent

Shimano recently filed an application with the United States Patent Office that's raising eyebrows and all sorts of questions.

The patent appears to outline a completely interconnected, electronic component system—as in, you hit a button that drops the seatpost and the suspension travel and damping automatically change as well. Pure conjecture here, but if I were a betting man, I'd guess that lowering the seatpost as you begin to drop into a steep descent might automatically increase your travel and reduce the compression damping on your fork and rear shock. Think of it as an e-version of BMC's Trailsync dropper.

Bombs away.

That's what it looks like from here, at least. Patents are a strange beast to wrestle with; they are at once incredibly detailed and obscure. Companies need to set precedent and protect their emerging technologies without exactly giving up the goods. It's a weird, linguistic dance. You can pore through the patent application here, but the bit about suspension travel, damping and seatpost interconnectivity is evident in the patent filing.

Shimano has never been a company bent on courting controversy, so I wasn't surprised by their response when I requested an official company statement on the patent.

"Shimano is constantly in development of new products, but does not comment on rumors, innuendo or speculation about products whether they are in development or not.”

Well, okay then. The company doesn't want to deal in speculation, but I will...it's in my job description.


An Electric World...It's Coming

It's not like Shimano has been hiding their electric intentions. They debuted Di2 for road bikes in 2009 and rolled out e-XTR in 2014. We've tested the stuff extensively. But as we noted in this double header XT Di2 review, while novel and accurate, electronic shifting hasn't been a game changer in the dirt world. It seems like a fair bit of wires and hassle to accomplish a task that a $3 steel cable already does pretty damn well. It kind of makes you think that maybe the end game was always something much bigger than moving a rear derailleur left and right.
Shimano Patent

Likewise, electronically-activated suspension has been around for a good long while now. K2 had its "Smart Shock" back in 1997. Fox rolled out its electronic iCD suspension waaay back in 2012. Magura has had acceleromator-equipped suspension for years as well. But getting those suspension components to "talk" to non-suspension components? That's a new trick, if not a logical progression. That patent suggests it may soon also be a reality.

But the patent indirectly raises another question: Will Shimano's electronic dropper seatpost communicate with Shimano-branded suspension? Will Shimano become a major player in forks and rear shocks? When you consider that their biggest rival, SRAM, has its fingers stuck deep into the suspension pie, it seems odd that Shimano would continue to steer clear of the squishy-bits business. Might Shimano's moment arrive in the form of electronically-activated suspension that "talks" to their e-dropper post? Who knows. Shimano isn't in the business of conjecture and innuendo, but you're free to go whole hog.

Conjecture away.

what a patent covers is defined in the "claims". Unfortunately, sometimes those are not unambiguous, and that is when lawyers get involved.

 @Dangerous-Dan: exactly what I was getting at
  • - 1
 @Moe2344:
The main point I am getting at is that the drawing is really of no consequence. What matters is the "claims". The drawing is there to attempt to clarify what the claims are. It is not the drawing which creates the ambiguity. Shimano's drawing with wheels and suspension out of scale is of no consequence.

Also, if I could point to a product which was on the market which used one of the claims, then some or all of the patent would be invalidated. One unfortunate thing is that if a patent dispute goes to trial you can be sure that one or both sides will exclude anyone who they believe has a background that allows them to understand what the argument is.

 To be fair I would have thought Magura would have been working on something like this. After all they already have wireless operation of damping and saddle height adjustment. It shouldn't take much more than some lines in the software to trigger it all simultaneously. That said, the suspension travel is a different beast. It usually takes some rider weight adjustment to operate these on the fly (like their older Flight Control travel adjust). If you also need to put your weight on the saddle simultaneously to drop that one, it isn't going to make things any easier. Not sure how Shimano is planning to implement this.
  • + 21
 These developments I can actually get more on board with vs changing already set standards every two years just because.
  • + 13
 Did anyone read the patent if you get far enough it really sounds like it's for dropping a post that has adjustable angle, suspension adjustment, and everything described in the article but it also sounds like it's designed to work with an ebike motor someone elts smarter than me should read the patent but it sounds like there talking about an ebike that senses your speed adjusts the motor and suspension similarly to autos. The wording is kind of misleading and you can notice that they refer to adjusting when talking about suspension and seat post but assisting the bike in other portions. I can't be the only one who got that vibe after reading it maybe I'm crazy o thought the comment section would be on fire about it. It's a little long the first section doesn't tell you much but the longer descriptions are more useful.

 @loganflores

The first claim in the patent says it all:

1. A bicycle control device comprising: an electronic controller that controls an operational state of a bicycle component based on at least an operational state of a bicycle electric assist unit, the bicycle component including at least one of an electric suspension and an electric adjustable seatpost.

As far as I can see, all the other claims are rooted in claim 1.

I am an engineer not a patent attorney, but I have been involved in the patent process up to my wallet. After a very quick read it looks to me like this patent covers an integrated suspension control module for a bicycle with an "electrical assist unit", so all the hardcore technophobes can go find something else to worry about.

As an aside, I have just installed an electronic shift group (Campagnolo EPS) on my road bike. It is still too snowy to ride it on the road, but on the test stand I really like what I am seeing. Uniform force to actuate the shifts, multiple shifts by holding the lever in the actuate position, the front derailleur trimming automatically.

And if it fails I can shift manually at a stop. I had to do that last fall when my SRAM shifter on the tandem failed on tour in the middle of nowhere in Scotland. I just don't see what there is to hate about electronic shifters. They will be as good or bad as the design, craftsmanship (stow it JustinTrudeau), and materials allow.

 @Dangerous-Dan: Well I was referring to sections towards the bottom I think 0076. It refers to a part 40 on the pic it's in the center of the bb maybe it's the power meter though. The way they refer to part 40 throughout seems to reference some sort of motor.
  • + 2
 @loganflores:
part 40 does indeed reference an electric assist unit.

I copied this from a patent attorney's web page. Not sure if it makes the whole thing more clear, or less:

The claims are the heart of a patent, in that they define the limits of exactly what the patent does, and does not, cover. That is, the patentee has the right to exclude others from making, using or selling, only those things which are described by the claims.

Since the claims all refer to an electric assist unit, it seems to me that this patent is about e-bikes only.

 @Dangerous-Dan: that was the point I was making nobody had mentioned it. I didn't bring it up to cause a scare in the ebike hate crowd I'm not sure how I feel about them yet my first inclination is usually the freedom of choice I.e it's not for me but who am I to tell you what to do. On the other hand it does effect me in a way so whose rights are more important. the guy wanting a little cheat on the way up at the possible cost of our trail rights I don't know. Time will tell.

 A blocking patent by Shimano... something they have deemed to be beyond a current trade secret. The patent has to be novel and with no prior art available.

 Good thing no gearbox and a motor! Dropping your seat post means going through some rough stuff and adjusting your front and rear suspension all at the same time! That's forward thinking, innovative and with Shimano, it will work! They got to work on that head angle though, not Enduro enough!

 This thread pains me. For one I welcome a electronic dropper post especially if it works. 2 shimano isn't a dying company and as said above clearly make a lot of money still. If they made a whole system that was electric that controlled it all we'd have some pretty cool stuff come up in the future. They really do make the best stuff. Yes they may not be at the top of the mountain game with "innovation" but there stuff works. Ever try finding anything eagle anywhere in stock?

 @freeridejerk888: that's valid. it's probably just because i'm more used to it. i also havent gotten around to getting a dropper yet, though i do want one eventually i think. i'm not familiar with the power the system uses but it would be cool if it could charge from riding. i understand that could cause rolling/pedaling resistance but realistically it wouldnt have to be creating resistance all the time. dont get me wrong, i love how precise and quick the shifting is and that all you have to do is press a button. i'll probably end up getting it and have a cable backup that i keep in my car. i just like the idea of not having to think about it and all i need is a shock pump and to mess with the barrel knob.

 Do we want to be reliant on Batteries to MTB? Yeah i have a road bike (dotn start) with DI2 and in the cold I ran out of power and got stuck in big ring. I dont want that on my MTB, suspension that dont work when it runs out of battery or seat post stuck in high position. More stuff to go wrong, mechanical analog all the way. It would have to have spectacular capabilities like terrain prediction for suspension. But it would end up like driver aid on f12 car. the skill is in the human feeling and driving the thing. We need manufactures to solve actual problems like DH tires that dont stop greg minnaar winning a race. It like the car industry with reverse parking cameras, they reduce the visibility in the back so they can sell you a screen you look in the car at to reverse... so you are not looking at the direction you are going and have no idea of scale or peripheral vision. So not sure if its going to actually solve any of my MTB problems?

 I love the idea that the rear mech is better because it doesnt have a cable, but... there is a cable going to the battery.

The benefit of electronic shifting is... mmmm.. there is a battery to worry about, environmental impact of battery and battery disposal, additional supply chain constraints (probably sea freight compared to air freight for no batteries), additional change control, more parts to fail (lower reliability), more expensive... looks like marketing v engineering. (I work in R&D so know the battle all too well).
  • + 1
 @betsie:
There doesn't need to be a cable between the shifter and the derailleur. RF for short distances can work well with a fairly low power consumption. With an RF system, the shifter is 2 buttons in a case with a small RF circuit.

It is much simpler than the abomination I currently have on my bars. My SRAM shifter failed on Skye last fall, and since it was not Shimano I couldn't find a replacement since the one bike shop that might have had one was closed.

Using a removable cell adds some complication, like sealing against water intrusion, but allows the components to be shipped and locally sourced cells added. Li Ion cells can be safely disposed of, and much of the material can be reclaimed.

And on a long travel suspension frame, an RF based shifter eliminates possible issues with cable flex and pinch. The cost is higher, and reliability will depend on the design and workmanship of the manufacturer.
  • + 1
 @Dangerous-Dan: BLE can communicate over significantly longer distances than from the mech to the shifter. I could guess which IC they use for their BLE. Between 2 companies but based on their developmemt time I would be pretty confident who they use. The BLE will have a separate registration for every country they sell in which costs money and conforming to Red will have just cost Shimano a few dollars for a low volume niche part which the consumer will be paying for. As for rechargeable batterie's, there is lots that goes on in the background that consumer's don't realise. I failed 5 supplier who wanted to supply us a battery for a medium volume medical device. Max 1 million units per year currently. As for sealing. It looks like they might have an external battery for capacity, sealing is not an issue and makes the design more simple in some respects as it frees up valuable real estate for the motor and controller which will be a basic motor and drive I would guess.

 I like the idea of improvement so I think it's nice to have the option for an electronicly activated drivetrain. I've read so many articles about Di2 that I think if I had the money I would buy one to give it a try... but still would have the wire "monkey adjustable" drivetrain just in case.. now.. here's a question to one of the points of the video: how come no one worried about still having an option when 27.5 hit the market?.. if 27.5 is an improvement great... but the 26" option is gone. I hope it doesn't go down the same road when electronic shifting becomes the benchmark... I would still like to have the OPTION of the three-buck wire activated drivetrain...

Solid, crisp shifting. And the extra super low gear/ability to run a larger front ring is very welcome while climbing out here way above sea level and the long descents. My home is over a mile high. My regular trails are 6000-8000 feet (1800-2400 meters). Is it needed at everyone's trails? No, but it sure is nice here.
I am eagerly awaiting Shimano's answer since it will not doubt be solid, and most likely cheaper than SRAM alternatives.

 @bman33: I guess my point is that you're right, they probably will announce it within the next few years. It will be a couple years until it's actually available for purchase though and it'll only be at the XTR level. It'll be another year or more until they announce XT then tack on one or two until that becomes available so...
Best case: 4-5 years
Worst case: a decade

 @kwapik:
I ride my SLX 1x10 for 4 years now with 80€ spent in cassettes and chains- still works flawless.
Currently with sunrace 11-42 and the oneup upgrade for the der.

Currently deciding between Zee 1x10 or SLX 1x11 for my new bike...
  • + 2
 @NotNamed: I personally didn't like Zee on 11-40 cassette, I felt it's pain when shifting to 40. Dunno how it shifts to 42. But maybe it was my setup. Personally I find my 1x11 XTR nowhere better than 10sp SramX0 shifter coped with X-9 type 2 rear mech. I am actually waiting with my cash in my teeth for a x-9 type 2 mid cage to pop up on classifieds. That is hands down best drive train I have ever owned. I would never buy XTR I got it. If you go for 10speed Shimano I would still recommend you to go for XT instead of SLX/Zee since it is a sturdier construction both for paralelogram and for the cage, then pulleys are also better - so you will actually save yourself some money in the end, and more probably than not, save yourself some hammering it back to relative true. I have bent 2 10sp SLX and only one could be saved. The cage on SLX, Zee is a pain in the arse to get right after it gets bent since the chain will keep on dropping between the pulley and the cage. Anyways If I was getting a 10sp drivetrain now, I'd go for Sram. My x-9 type 2 went strong for 4 years and 2012+ X9 shifters were great too.

 what happens when you aren't pedaling and try to e-shift? or even two or three shifts without pedaling, or if limit screws or b-tension screw aren't set up properly, does it explode? honest question. (i apologize for not reading through all the comments before asking)

 Same thing that happens when you aren't pedaling and try to normal shift. Di2 has no limit screws, it calibrates itself.

 @TheRaven: thats not true, Di2 has limit screws, and requires an initial setup/calibration.

 @TheRaven: so you are saying it's so advanced it installs itself on the bike and then sets itself up and then works flawlessly until it needs to read calibrate itself. This sounds like fake news to me

 I read the article, and also watched the vid at the end...

First on the article, it could lead to something big... or, it could be a matter of "patent it just in case someone else goes down this path", and they may have decided not to, possibly. Either way, really neat little blub, I love stuff like this.

Regarding the vid:

I just wanna say, I love what KS is and has been doing as a company. They started out making cheap parts en mass quantities as recently as 1991... look at them now, only 27 years! They've been a great alternative at a nice price point for a while now, and they're rolling out with new stuff year in and year out- keeping up with the "big dogs". I have a lot of respect for them as a company. I hope they're able to grow their market share so they can keep coming out with nice stuff.

 " But getting those suspension components to "talk" to non-suspension components? That's a new trick, if not a logical progression. That patent suggests it may soon also be a reality."

... and ideas for connecting suspension with dropper adjustment with the possibility to link it to gear selection/cadence/...based on a logic have been pointed out in the public domain for at least the same time as electronic adjusted suspension, gearing and droppers exist.

 Shimano plays the long game. You can bet there will be some cross tech with mix and match mechanical and electronic systems. There was a seatpost rumor a while back and that silent hub? I see the ebike world being all over this. Big S will also have amazing stuff without a battery.

I don't have the money for an electronic shifting system, but my trip in the ambulance and 7 hours in the ICU when a ghost shift at full sprint sent me OTB into a concrete curb tells me I might be tempted by one, if only to avoid the pain of a shoulder blade broken in 3 places and face like Frankenstein's panda.

 I have tried di2 at the shimano booth before. It was nice, but not really nicer than a mechanical system. The price and ergonomics put me off. You can't get the FIREBOLT (!) shifters in ispec. That's a big no no for me. Plus Santos guys say, if you run full length housing you just need to change the inner like once every two years or something.

 @stumpymidget: MTB electric shifters are somewhat slow in this process, plus you need to look at the gear display to know what gear it shifted to as opposed to knowing "that was 4 gears."

I have spent a decent amount of time aboard a xt di2 set up and the technology is *almost* there, but I still like the standard cable actuated stuff better.

 Easy! Just raise your seat post 20mm (not 30, that will shift 5 cogs), move your weight forward on the bike, hold the shift lever, throw away your back pack in favor of frame mounted bottle, and then make sure Strava can report that you are at the bottom of a saved ascent. Then the computer will know how many gears you want to move up automatically and lock out your shocks!

When about to descend, put on the full face helmet, drop the seat by at least 40%, lean back, change to flat pedals, and push record on the Gopro so that the on board computer will give you more travel as needed!

Seriously, the future is simple.
