Round Up: 5 Interesting New Patents - A Voice Controlled Bike, Electronic Braking, & More

Mar 26, 2020
by Dan Roberts  



Every month there are a bewildering number of patents filed and granted that relate to the bike world. Lots would be seen as somewhat wacky and useless to most of us, but hiding away in the mass of paperwork lie some interesting inventions that can often give light to which direction a brand is moving in. Sometimes they're put in place after the launch of a product, more to protect that particular product and any future ones that would share the same technology.

Not absolutely everything can be patented though. They are available in all fields of technology but must be new, involve an inventive step and are capable of industrial application. Although looking through some patents they do meet through those criteria by the skin of their teeth.

Patents do have many benefits. They can provide incentives for research and development departments or firm and they put all these new inventions out into the public domain, providing more information and perhaps inspiration for future inventions. They also enable small companies or individuals, who can afford to patent and defend their patents, the ability to become licensors, accruing capital from their inventions while they might not necessarily be able to implement them in a product themselves.

They do, however, receive a hell of a lot of flak. Some people see them as blocking innovation and waste resources. There are rules, regulations and criteria in place for patents, but some companies and individuals do scrape very close with low quality and broad patents that have the potential to do more harm than good. Like most things in life, it's a balancing act and also requires doing things for the right reasons.

Patents usually stand for 20 years from the date of filing.

Here's the start of a regular round-up looking at the more interesting patents we've come across in the past few months.





Specialized Suspension System
Patent Number US 2019300096


Specialized's patent on their recognisable Demo and Enduro suspension layout is a perfect example of a brand patenting a layout to protect their bike design for the years to come, and possibly hints at more bikes following a similar design than just the Enduro and Demo.

The patent must describe the invention, and so layout, so there’s lots of talk of frames, subframes, pivots and articulation. In addition to this there are quite a few drawings accompanying the patent to illustrate embodiments, some of which we can recognise as bikes in production, and others with possible variations on the layout, some showing less amounts of concentricity between pivots which could up the amount of adjustability for the designers, and some with different shock placements increasing the amount of concentricity with pivots.

Specialized's layout isn’t a million miles away from the Canyon Sender, both employing a four-bar layout to connect the rear wheel to the main frame and so dictate the axle path and responses to acceleration and braking, then a second set of links to drive the shock. Specialized differed from Canyon in making the links that drive the shock share the same pivots as the links connecting the rear wheel to the mainframe, in theory, reducing the amount of adjustability in the design to somewhat separate the anti-squat and anti-rise from the leverage ratio. Now some of their embodiments in the patent show the ability to have more freedom in pivot placement.

The patent also describes how it came about due to wanting a low center of gravity by having the shock placed as low in the frame as possible, citing other more conventional designs with the shock placed higher as being detrimental to the bike's handling.

There is also reference to longer travel suspension designs often having great amounts of forwards axle path, especially at the end of travel. It seems Specialized sought to combat these two points, although the amount of rearward axle path in the new Demo 29 is only around 3mm before travelling about 23mm further forward from the sag point to the end of travel. The shock is, however, positioned incredibly low in the frame, and with the length of the shocks on the Demo 29 and Enduro it puts that weight lower down.

The patent is valid in the US and Germany, covering the two most important areas in the bike selling world for companies as big as Specialized.





Spring Rate Adjuster
Patent Number EP 3594526A1


Öhlins design and manufacture suspension equipment for a whole host of applications. Their parts show up on all manner of motorcycles, high performance road and race cars and, in recent years, mountain bikes too.

They have recently had a small flurry in patents ranging from spring and damper designs with ease of service features, position dependant systems and even a fully electronically controlled system that uses a series of consecutive events to control the suspension and reduce system power usage, rather than monitoring what is happening at every single millisecond.

The patent here focuses on a system for adjusting the spring rate characteristics in a shock, or fork, without having to take the shock apart. Something similar to what a few smaller, mainly suspension tuning companies have released. But if someone like Öhlins is patenting it then it could well find its way into production suspension parts without the need to purchase aftermarket kits to modify your current suspension.

As stated, the removing, replacing and rearranging of volume spacers is time consuming and not all riders have the know-how or tools to do the work themselves. Having a system able to do this from the exterior of the shock is of huge benefit.

Where Öhlins differ in their approach, and giving them the availability to patent it, is that they change the volume inside the air chamber indirectly by adjusting the volume of the damping area housing the damping fluid. The two working areas, one gas-filled and one damping fluid-filled, are functionally connected to each other to allow this adjustment. One side effect of this method of adjustment means that the shock is less vulnerable to a performance drop due to varying amounts of oil inside, for example, after a service.

Their artwork, and the patent text, show a means of adjusting the volume via a worm drive and what almost looks like a standard Öhlins rebound adjuster shaped knob. This enables the adjuster knob to be placed at 90 degrees to the moving elements inside the shock. Mounting the system inline wouldn't be possible due to the shock eyelet needing space for the bushing.

As is the case when adjusting air spring volume with tokens, the pressure is reset to the new volume inside the shock. A side feature of this construction is the ability to adjust ride height - for a given gas pressure inside the shock, adjusting the volume would change gas pressure inside, adjusting the ride height of the shock and so the bike.

This Öhlins patent, along with all their other recent patents are valid for Europe.




DT Swiss Voice Controlled Bike
Patent Number EP 3552941


Lurking away behind a very plain title is a patent from DT Swiss that became very interesting. Not least because of the lengths that DT go to suggest ways in which the patent and invention could be used.

Many people now have systems in their homes from Amazon or Google to control or provide information based on voice commands. The DT Swiss patent essentially outlines a system to control and give feedback on the bike from voice commands.

It mentions monitoring and control of suspension systems, drivetrains, lights, seat posts, electric motors used for drive assistance, battery units, tire pressure monitors, bike behaviour sensors, rider performance sensors and GPS sensors. A whole connected system of a bike constantly monitoring the state of its sensors and allowing control to parts of the bike through voice command and providing acoustic, optical or vibrating feedback.

It even suggests vocal encouragement from the bike when it realises you’re in a challenging climb or descent as well as outputting information and feedback to displays in goggles or devices in your helmet. Based on the operating conditions the bike could also provide warning to the rider for them to make adjustments or be aware of things about to need a service or even incoming weather.

There’s mention of your personal system being trained to recognise your voice when in a group of people and with other noise disturbances. So, you’d have to do a really good impression of your friend to operate his bike for him. There’s even a mention of engine braking on ebikes and brake energy recuperation, hinting to an even larger system of a bike.

The patent description is fantastic for a read into perhaps the future of electronic integration in the bike world. DT’s patent is valid for Europe, Germany and the US, so essentially covers the major players in the bike world.





Shimano Electric Brake System
Patent Number US 2019359187


Shimano always do a good job of wording patents, as was shown when they cleverly disguised a potential gearbox transmission in their recent patent labelled sliding component and bicycle internal transmission device.

Shimano also files and is granted a barrage of patents monthly. Some of them less interesting than their gearbox, referring to chain and cassette technology.

This particular patent, however, refers to electronics in the braking system, and the disconnect of the “operating member”, or brake lever, from the rest of the system. For lack of a better description, a drive-by-wire brake.

The patent uses a detector to monitor the brake lever and turn its inputs into a signal that the detector picks up. A controller uses these inputs to control the electric actuator which operates the brake calliper. The patent drawing show examples with the whole system inside the brake lever of a road bike, but given that there would be a mechanical disconnect between the brake lever and the calliper, the system could be anywhere else and potentially remove the need for brake hoses around the handlebars.

With the removal of that mechanical connection it seems there are a lot of challenges in the way to accurately monitor what is happening at the brake lever and process and act on those inputs fast enough. Lots of fine processing of lever travel and pressure is done so quickly by the brain and fingers without us even noticing, and to some degree this needs to be replicated in the electronics and mechanical aspects of this system.

If there is a separate system used for actuating the brakes given the input from the brake lever, then this could also be one potential aspect in an ABS system. More sensors detecting bike and wheel speed would be needed but the operation of the brakes being controlled by an electric system could allow Shimano to vary the brake pressure for the given inputs and reduce brake locking and skidding.

Shimano’s patent is valid for Japan, China, the US and Germany, covering all the major countries important to bikes and providing enough patent cover for effectively the world of bikes.





Tektro Brake Wear Monitor and Warning System
Patent Number US 2019376572


Tektr'os patent is a little easier to decipher from the title, but hints at some useful technology to help riders out in the safety department.Their patent embodies a device to monitor the wear of your brake pads and give out a warning when the pads hit a point when they need changing. Most of us wear pads down until the backplates are hitting the rotor, and Tektro's patent sees the pads giving out a warning far before this point to ensure proper braking performance.

The system works by way of a small pressure switch in between the two sides of the pad spring. When the pads are new, or above the wear limit, the switch isn’t pressed into activation. Once the pads wear below the pre-defined limit the switch is activated and a warning signal is produced. The patent describes how this warning signal could be transmitted to the brake lever where a warning light comes on once the wear limit is reached.

Tektro also go on to describe a system with two switches. The first handles the wear of the pads, and a second switch is used to monitor whether the brakes are in use or not. There’s not much further on possible uses for this, but it could easily be used as the sensor in a brake light system. With Tektro's claims of improving the safety aspect of road, mountain and other bikes it could be put into place on commuter and road bike to warn surrounding traffic when the bike is braking.

Tektro's patent is valid for the US, Taiwan and China.

 @WAKIdesigns: Only after ShitmaNO got thousands from some of their dedicated "partners" for "licensing". I dunno, I have not seen a single XD seize where I am (nor have I heard of it, at least not like the shit show that is SRAM stoppers).

That said, I have some road wheels that say Campagnolo 9 Speed on them....well, they are running 12 (and are going on 15 years old). Odd how a certain design in the road world can go on and on. Then again, a road groupset (that I opt to ride) is 300% more costly than XTR Di2or XX1 AXS.

 @RoadStain: I guess we both know that both XD and Microspline are a result of whiny wendies who think they need largest possible range. Had we stayed with 11t smallest cog we'd still all be fine. I don't know who uses 10t in which conditions, it's a piece of crap of a cog, very inefficient, wears out very quickly and good luck spinning that on a downhill course with your rear mech being fully contracted. i tried that on fresh cassette and chain, no thank you, never again trying to pedal to big ass jump using even 11t cog. Just like roadies would be way better off with cassettes like Miche 14-30 instead of running 11-25, I can't wrap my head around it. It's an obvious disadvantage to anyone who is not going to do a sprint on a steep descent in Alps and with 14t in the rear would need a gigantic chainring.

 @Zimbaboi: not to mention how bloody shitty Sram cassette is with ghost shifting at the bottom. AXS - no ghost shifts, hell yeah - Another great way for Sram to build space industry around an issue they could have solved with ardous, time consuming, yet simple testing over and over again until they get it right. Especially since they machine the whole thing anyways, they can get the tolerances perfect. Just like they did with DUB. Instead of using good bearings with good tolerances on GXP and fixing the crank preload, they reinvented the whole thing all over introducing lots of confusion and it's still shit! Big Grin Now Shimano caught up n every front and beats them senslessly in the drive train department - better quality, lower price.

 The good news is that you never need to worry about the dangers of your electronic brake dying because your bike will have already ceased to shift, pedal assist, produce light, charge your phone, tell you what gear you're in, respond to your commands, or shout uncanny phrases of encouragement.

 The whole idea of putting the shock low down in the frame to lower the center of gravity is a bit silly if you also run a water bottle on the frame, which then usually has to be placed much higher. Water bottles weigh a lot more than rear shocks! Seems better to have the water bottle mounted as low as possible and the shock higher, if lowering the center of gravity is your aim. Not to mention that generally the higher up the shock is the better it is out the way of dirt and debris.
  • 11 3
 This is actually a good reason to have water bottles under the down tube

 I would think low shock positioning matters most on dh bikes, which have the heaviest shocks, no water bottles, and a need for the best handling possible

 Depends if you use a coil shock or not. I would bet the old enduro has a better CG with a 3/4 full bottle and air shock than the current one.

 It would be more than just the shock. You would also factor in the linkage and bearings and such. And a water bottle isn't always used and isn't always full. I would encourage you to drink all of your water at the very beginning of your ride......The more you drink the better your bike handles. The faster you drink the faster your bike gets faster!!

 Does anyone else want to see that design on a stumpjumper? 140r/150-160f.

and while you're at it steepen the damn sta already, slacken and lengthen (don't go crazy), and fix the lack of both antisquat and support.

Yeah that design may be overkill for the everyman's trail bike, but the stumpy has fallen way behind the ripmo, switchblade, sb130 (all of which i've tried against the stumpy and evo) and many more of its competitors.

looks like a sick design and with rave reviews including decent pedaling against it's peers (the Enduro). fix your shit specialized! go all in with the next stumpy instead of doing another boring bike that's back of the pack. you're welcome.

 Engine braking for recharging batteries sounds handy. Perhaps with this setup, one could ride an e-bike perpetually up and down hills if a small enough percentage of the power on the way up is from the electric motor and if there is a sufficient amount of braking on the way down (in other words, if the hills are sufficient gnarly and steep).

@dan-roberts There is no such thing as a worldwide patent.

 I'm a little bit sceptical to voice operating systems, as one specific phrase from "Altered Carbon" episode activates my iPhone's Siri protocols. And wireless brakes? Mechanical is reliable and, of course, it is still possible to have a catastrophic failure with any brake type, but forgetting to charge your derailleur system is one thing, losing your braking power abruptly is another. However, I believe they already figure it out. Maybe some redundancy?

 It will be interesting to see if the bike world can really go where the car world has gone with EVERYTHING being electronic. A standard 4-door sedan is 300-500lbs heavier on average than it was 20 years ago and that's with improving technology and lighter weight parts. If we start having electronic seatposts, drivetrain, brakes, voice control, etc. will every bike eventually be 35+lbs?

 I see another major problem with the electronic braking. Current systems use oil through a long hose which in mtb especially can still overheat and cause brake fade/failure. Loose the hose and the tiny bit of oil in the caliper will overheat so much quicker. I understand wanting to get rid of cables on the road side (aero) but unless they've come up with some wonder way of cooling the caliper then.... Well.... Say bye bye brakes
  • 3 1
 It's a problem that currently exists with TRP hy/rd. Since there aren't a ton of high performance user utilizing them it's doesn't get much acknowledgment, but I've seen several of those systems come into our shop with scorched oil, which is something I'm familiar with from my time with larger hydraulic systems and automatic transmissions. They have a huge compensation bladder and master cylinder reservoir, I'm assuming to deal with large volume changes due to thermal expansion. They also have poor airflow around the pads, which has to compound the situation.
Shimano really preaches about brake heat in road systems being typically higher than in *most* mountain systems, due to longer sustained braking from high speeds and smaller rotors. I'd assume they'd be ahead of thermal management. And since its Shimano they'll refine the technology for a decade before releasing it.
SRAM however will have their AXS wireless brakes out this fall, which will suffer from massive teething pains, and kill dozens of cyclists, there will be a recall, and you'll be able to get some new improved ones under warranty. Those units will only kill tens of cyclists.

 Older Magura disc brakes had small knobs on the ears of the disc brake pad backing plate. When the pads were due for replacement, the backing plates had moved so close to the disc (as the pad material got so thin) that the knobs would hit the spokes of the rotor so you got this rattling sound. That was enough information. They quit doing that with Louise 2007 (which shares pads with Julie FR, Louise 2008 and Marta 2009). But yeah, it worked quite well.
  • 2 1
 If this could be integrated into a value brake it would be a game changer. Trying to explain to an owner that their brakes are completely hosed and require new rotors as well is extremely frustrating. On a high-end bike most owners will accept it, but grumble. But telling a person with a $400 bike that they require $40 in pads, $50 in rotors and $60 in labor because they have ground their backing plates into the rotors is downright painful.
I've even had to replace calipers a few times because the backing plates are gone and the pistons are ruined.
Of course I've had to replace wheels because the brake pads studs have cut the rim sides nearly through on rim brakes. So it's not unique to discs.
