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.
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 240,000 patents, there are 80+ innovation areas that will shape the future of the industry.
Within the emerging innovation stage, self-cleaning toilets, and smart waterproofing are disruptive technologies that are in the early stages of application and should be tracked closely. Automated slurry-blast tools, sensor-integrated doors, and robotic excavators are some of the accelerating innovation areas, where adoption has been steadily increasing. Among maturing innovation areas is work vehicle cruise control, which is now well established in the industry.
Innovation S-curve for Internet of Things in the construction industry
Self-cleaning toilets is a key innovation area in Internet of Things
Self-cleaning toilets are toilets that have been designed with features and technologies to efficiently clean themselves after each use without the need for manual cleaning. They have various features such as automated cleaning systems, siphonic flush toilet systems, and jet holes strategically positioned for effective waste evacuation.
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 150+ companies, spanning technology vendors, established construction companies, and up-and-coming start-ups engaged in the development and application of self-cleaning toilets.
Key players in self-cleaning toilets – a disruptive innovation in the construction industry
