The construction industry continues to be a hotbed of innovation, with activity driven by an increased focus on environmental sustainability and workplace safety, and the growing importance of technologies such as the Internet of Things (IoT) and robotics. In the last three years alone, there have been over 248,000 patents filed and granted in the construction industry, according to GlobalData’s report on Innovation in Construction: Pneumatic door closers.

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.

80+ innovations will shape the construction industry

According to GlobalData’s Technology Foresights, which plots the S-curve for the construction industry using innovation intensity models built on over 179,000 patents, there are 80+ innovation areas that will shape the future of the industry.

Within the emerging innovation stage, mullion-transom curtain walls are a disruptive technology that is in the early stages of application and should be tracked closely. Heat-insulated glazing panels, drainage gully grating, and acoustic ceiling panels are some of the accelerating innovation areas, where adoption has been steadily increasing. Among maturing innovation areas are abrasion-resistant decorative flooring and road construction milling tool, which are now well established in the industry.

Innovation S-curve for the construction industry

Pneumatic door closers are a key innovation area in construction

Pneumatic door closers enable the control of heavy door opening and closing, avoiding the risk of doors slamming. Pneumatic door closer systems are powered by gas drawn in from the air and the compressed. They are generally cheaper and less complex to install and maintain when compared to hydraulic systems.

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 10+ companies, spanning technology vendors, established construction companies, and up-and-coming start-ups engaged in the development and application of pneumatic door closers.

Key players in pneumatic door closers – a disruptive innovation in the construction 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’.
