The automotive industry continues to be a hotbed of innovation, with activity driven by the need for enhanced driving experience, fuel efficiency, and engine performance, and growing importance of technologies such as electrification, and connected and autonomous vehicles. In the last three years alone, there have been over 1.2 million patents filed and granted in the automotive industry, according to GlobalData’s report on Innovation in Automotive: Power window tensioners. Buy the report here.

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 stabilising 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.

290+ 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 619,000 patents, there are 290+ power window tensioners s that will shape the future of the industry.

Within the emerging innovation stage, resilient spoke wheels, auto-transmission lubrication circuits, and ignition switching engines are disruptive technologies that are in the early stages of application and should be tracked closely. Engine purge actuators, electro-dynamic braking, and adsorptive vapour recovery system estimation are some of the accelerating innovation areas, where adoption has been steadily increasing. Among maturing innovation areas are collision avoidance braking control system and direct injection type engines, which are now well established in the industry.

Innovation S-curve for the automotive industry

Power window tensioners is a key innovation area in automotive

Power window tensioners are hidden inside the door panel, where they remain until they malfunction. When power is applied to an electric motor or in the case of manual windows, when the window crank is turned, the power window tensioner is the mechanical assembly that raises and lowers a window.

GlobalData’s analysis also uncovers the companies at the forefront of each power window tensioners and assesses the potential reach and impact of their patenting activity across different applications and geographies. According to GlobalData, there are 30+ companies, spanning technology vendors, established automotive companies, and up-and-coming start-ups engaged in the development and application of power window tensioners.

Key players in power window tensioners – a disruptive innovation in the automotive industry

‘Application diversity’ measures the number of different applications identified for each relevant patent and broadly splits companies into either ‘niche’ or ‘diversified’ innovators.

‘Geographic reach’ refers to the number of different countries each relevant patent is registered in and reflects the breadth of geographic application intended, ranging from ‘global’ to ‘local’.

Aisin is one of the leading innovators in power window tensioners with 179 patents. Aisin’s power window tensioners integrate an anti-pitch device that stops the window, as soon as it recognises an object on its edge while it is being pulled up for closing. The window tensioners have a power backup, which is supplied to the window circuit even after the engine is turned off. In case someone forgets to roll up the windows, this feature saves from the hassle of turning the ignition on again, just to pull up the windows. It also allows the driver to control the windows with just the touch of his fingers. Other companies innovating in this technology domain are Kia, Honda, and Denso.
