The automotive industry continues to be a hotbed of patent innovation. Activity is driven by the need for enhanced driving experience, environmental concerns, and electrification, and growing importance of technologies such as battery technologies, electric vehicles, and connected vehicles. In the last three years alone, there have been over 720,000 patents filed and granted in the automotive industry, according to GlobalData’s report on Innovation in automotive: armature core manufacturing.

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 Foresight, 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, multi-spark ignition, integrated multi-motor drivetrains and vehicle auxiliary drives are useful technologies that are in the early stages of wider application and should be tracked closely. Solar range extenders, turbocharger shaft bearings, and multi-lamellar clutches are some of the accelerating innovation areas, where adoption has been steadily increasing. Among maturing innovation areas are auto-transmission lubrication circuits and electroluminscent vehicle displays, which are now well-established in the industry.
Innovation S-curve for the automotive industry
Armature core manufacturing is a key innovation area in automotive
The silicon steel laminations that make up the core of the armature are separated from one another by an insulating varnish coating. These laminations help in reducing eddy current losses. The armature core might have air ducts for the axial air flow needed for cooling.
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 60+ companies, spanning technology vendors, established automotive companies, and up-and-coming start-ups engaged in the development and application of armature core manufacturing.
Key players in armature core manufacturing – 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’.

Robert Bosch Stiftung is the leading patent filer in armature core manufacturing. It recently developed a new device that can be installed on the shaft and contains an internal protrusion. The protrusion engages a knurled feature on the shaft, and the initial stresses can eventually be reduced, at least in part. Other key patent filers in the innovation area include Denso, Eto Magnetic, Continental, KYB, BorgWarner, and Kendrion (Villingen).
In terms of application diversity, Denso held the top position, while BorgWarner, and Kendrion (Villingen) stood in second and third positions, respectively. By means of geographic reach, Dubai World leads the pack, followed by Eaton and NOK.
