Samsung recently received a patent for a foldable phone that integrates an air quality sensor without compromising on the phone’s design. This innovative feature aims to help users monitor air quality in real time, addressing the growing concern about air pollution and the need for convenient, affordable air quality monitoring. @xleaks7 recently demonstrated a scrolling phone equipped with an air quality sensor based on Samsung’s approved patent. Growing concern for environmental health, coupled with the ubiquity of electronic devices, is driving the demand for devices that can monitor air quality.

Samsung designed this foldable phone to integrate an innovative air quality sensor without compromising on the device’s compactness, functionality or aesthetics. The goal is to provide more efficient, reliable and user-friendly air quality in portable electronic devices. The key features of this Samsung device are as follows

  • Sliding housing design: Adjust the display size and control the airflow to the sensor.
  • Movable Display: Flexible screen size to meet user needs while keeping the device compact.
  • Integrated Airflow Duct: Directs outside air to the air quality sensor to improve the accuracy and speed of air quality measurement.
  • Intelligent opening and closing mechanism: works according to the sliding movement of the case, ensuring optimal operation of the sensor by controlling the air flow.
  • Faster sensor response: This design helps the sensor respond more quickly to changes in air quality, providing users with timely information.
  • Prevents sensor contamination: Prevents internal components from sensor contamination, providing reliable air quality readings.
  • Space-saving design: No additional space-consuming components are required, maintaining the device’s elegant appearance.

Samsung’s new patent for a shrinkable smartphone

The new patent describes an electronic device that includes a proximity sensor, processor and memory. The proximity sensor, which includes a light source and a light sensor, emits light at dust particles in the air and measures the intensity of the reflected light. The processor then uses an air quality table to match the reflected light intensity values ​​to the air quality values.

Importance of patents

Patents are of great importance in various aspects, as highlighted by experts and sources:

  • Fostering Innovation: Patents are critical to fostering innovation by providing inventors with exclusive rights to their inventions, creating a financial incentive for further technological advancement.
  • Protection for Inventors: Obtaining a patent offers legal protection to inventors. It also prevents others from using or copying their inventions for a certain period. Normally, the period is 20 years from the date of filing the patent application.
  • Economic growth: By granting exclusive rights to inventors as well as companies, patents stimulate economic growth by encouraging innovation leading to the development of new technologies, products and industries.
  • Stimulating research: The exclusive rights granted by patents stimulate research and development activities because inventors can benefit from their inventions through licensing and commercialization opportunities.
  • Intellectual Property Protection: Patents protect intellectual property by allowing inventors to exclude others from using, manufacturing, or selling their products or methods of use for a specified period.
