The flexibility to regulate tire strain on the fly is probably game-changing, and we’ve seen just a few totally different Tire Stress Administration Methods (TPMS) previously few years. From the UCI-approved Scope Atmoz to the Gravaa KAPS system, these purposeful pressure-adjusting hub techniques have proven extra than simply promise. However even just a few high-profile race-winning performances utilizing the Gravaa system weren’t sufficient to maintain the model from going underneath. Evidently value has been a hurdle stopping TPMS from wider acceptance and industrial success (in addition to tubeless compatibility).
Which is why I used to be intrigued when a Swiss inventor named Bernhard Buergler reached out the opposite day with info concerning his new TPMS patent. Within the press launch shared by Breugler, he states that his not too long ago patented design (WO2025/261588) represents the following technology of TPMS, which can assist preserve these techniques alive whereas making them extra inexpensive, and due to this fact, extra commercially viable.
From the Patent Summary: The current invention pertains to a tool for adjusting strain in tires (19) of a car throughout operation, comprising a supply of strain (10a, 10b, 10c); an influx valve (12) for regulating the stream of gasoline from the supply of strain (10a, 10b, 10c) to the tire (19) and thus rising the strain within the tire (19); an exhaust valve (13) for regulating the stream of gasoline from the tire (19) and thus decreasing the strain within the tire (19); a wheel hub unit (30) capable of management the stream of gasoline to and/or from the tire (19); and an digital management sys- tem (21) in communication with and capable of management the supply of strain (10a, 10b, 10c), the influx valve (12), the exhaust valve (13) and the wheel hub unit (30) in an effort to improve and/or to scale back the strain in tires (19).
He believes that his system addresses the 2 main weaknesses of earlier techniques — value and complexity. Within the press launch, Buergler claims his TPMS is radically simplified in comparison with earlier designs, and that “through the use of off-the-shelf industrial elements, Buergler has drastically decreased the projected retail value to only 20-30% of earlier techniques.”
Not like the Gravaa system, which basically generated vitality to energy a small air compressor, in Buergler’s patented design, “the hub-mounted system incorporates a refillable tank for liquid CO2 and an array of micro-nozzles and orifices, which permit for the speedy inflation and deflation of a bicycle tire throughout operation.” On condition that CO2 can be used for inflation, it could finally be restricted in its inflationary capability, but it surely may additionally inflate extra quickly than a tiny hub-based air compressor (and maybe be lighter weight).
Buergler claims the “huge value discount is pushed by a radical design simplification and a extremely complicated, but cheap, 3D-printed manifold.” Like different techniques, a tube would nonetheless want to increase between the hub and the rim/tire for inflation and deflation. Moreover, a handlebar-mounted management unit can be used to manage the system, ideally “speaking with the system by way of Bluetooth or one other acceptable protocol.”
The patent description goes on to say, “In accordance with one other embodiment of the invention, a battery-operated micro air compressor is used as a strain supply. For this embodiment, sure downstream elements, particularly the strain orifice, may be omitted or simplified in its specs.” So, maybe a mini-air compressor and a compact, rechargeable battery might be used as a substitute of CO2, like a hub-based model of a conveyable electrical tire inflator.
It’s essential to notice that up to now, this newly patented TPMS design is simply that, a design. There are nonetheless loads of questions associated to inflation capabilities, charges, the burden of the system, and the controls. However these are questions that may’t actually be answered till the prototypes have been made. However, assuming it’s purposeful and fairly priced, it might probably lower one of many main boundaries to higher market acceptance of tire strain administration techniques.
Buergler is providing his patent on the market and is at present in search of a longtime business companion to assist carry it to market. ? The printed patent is well searchable should you’re excited about studying by it in higher element.
