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, multi-spark ignition, integrated multi-motor drivetrains and vehicle auxiliary drives are disruptive technologies that are in the early stages of 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 the maturing innovation areas are auto-transmission lubrication circuits and electroluminscent vehicle displays, which are now well established in the industry.

Key players in electric drive capacitance management – 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’.

Hyliion is one of the leading patent filers in electric drive capacitance management. It has developed a new capacitor bank that is more energy-dense and has a longer lifespan than previous capacitor banks. This allows the electric drive capacitance management system to store more energy and release it to the electric motor more quickly. Hyliion has also developed a new power electronics system that can handle more power than previous power electronics systems, allowing more efficient transfer of energy between the battery pack, capacitor bank, and the electric motor. Some other key patent filers in this space include Truma Geratetechnik, Zeppelin-Stiftung, and Porsche Automobil.
In terms of application diversity, CJ leads the pack, while General Motors and Deere stood in the second and third positions, respectively. By means of geographic reach, K-Ryole held the top position, followed by Randon Implementos and Shandong Heavy Industry Group.
