The automotive industry continues to be a hotbed of patent innovation. Activity in telescopic drive shafts is driven by smart manufacturing and production techniques, regulatory requirements and emissions standards, weight reduction and fuel efficiency, and growing importance of technologies such as lubrication and sealing technologies, forging and machining techniques, and smart sensing technologies. In the last three years alone, there have been over 1.7 million patents filed and granted in the automotive industry, according to GlobalData’s report on Innovation in automotive: telescopic drive shafts.

However, not all innovations are equal and nor do they follow a constant upward trend. Instead, their evolution takes the form of an S-shaped curve that reflects their typical lifecycle from early emergence to accelerating adoption, before finally stabilizing and reaching maturity.
Identifying where a particular innovation is on this journey, especially those that are in the emerging and accelerating stages, is essential for understanding their current level of adoption and the likely future trajectory and impact they will have.
300+ innovations will shape the automotive industry
According to GlobalData’s Technology Foresights, which plots the S-curve for the automotive industry using innovation intensity models built on over one million patents, there are 300+ innovation areas that will shape the future of the industry.
Within the emerging innovation stage, integrated multi-motor drivetrains, electric power steering (EPS), and post-collision handling are disruptive technologies that are in the early stages of application and should be tracked closely. Variable compression engines, V2V distance monitoring, and turbocharger shaft bearings are some of the accelerating innovation areas, where adoption has been steadily increasing. Among the maturing innovation areas are kinetic energy recovery system (KERS) and plasma-jet ignition, which are now well established in the industry.
Innovation S-curve for the automotive industry
Telescopic drive shafts is a key innovation area in automotive
A telescopic drive shaft is a type of mechanical device that allows an axle to move in and out, therefore, adjusting the length of the drive shaft. It consists of two or more tubular shafts that can slide in and out of one another, allowing for changes in length of the shaft. Telescopic drive shafts are commonly used in vehicles with a long wheelbase and agricultural implements to transfer rotation from a power source.
GlobalData’s analysis also uncovers the companies at the forefront of each innovation area and assesses the potential reach and impact of their patenting activity across different applications and geographies. According to GlobalData, there are 20+ companies, spanning technology vendors, established automotive companies, and up-and-coming start-ups engaged in the development and application of telescopic drive shafts.
Key players in telescopic drive shafts – a disruptive innovation in the automotive industry
‘Application diversity’ measures the number of applications identified for each patent. It broadly splits companies into either ‘niche’ or ‘diversified’ innovators.
‘Geographic reach’ refers to the number of countries each patent is registered in. It reflects the breadth of geographic application intended, ranging from ‘global’ to ‘local’.
