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

Interlocking type brake lining is a key innovation area in automotive

Interlocking type brake linings apply frictional forces to a cylindrical drum attached to the wheel during braking operations to decrease its speed and provide better control of the vehicle.

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 45+ companies, spanning technology vendors, established automotive companies, and up-and-coming start-ups engaged in the development and application of interlocking type brake lining.

Key players in interlocking type brake lining – 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’.

Patent volumes related to interlocking type brake lining

Nippon Steel is a key player in the interlocking type brake lining innovation area. The company’s interlocking-type brake lining helps in reducing emissions, running resistance, and engine displacement for better fuel efficiency. Nippon’s interlocking-type brake lining requires little maintenance, is more reliable, and offers protection. Stella Vermogensverwaltungs, Westinghouse Air Brake Technologies, RTX, and Akebono Brake Industry are some of the other key players.

In terms of application diversity, Nippon Steel held the top position, while Stella Vermogensverwaltungs and RTX stood in second and third positions, respectively. By means of geographic reach, ITT leads the pack, followed by Nuova FourB and Nippon Steel.
