Specification

Description:TECHNICAL FIELD
[0001] The present disclosure relates to a field of a personal safety device. More precisely, the present disclosure relates to a smart safety device and method for facilitating real-time protection to users in emergency events or threatening situations.

BACKGROUND
[0002] The following description of the related art is intended to provide background information pertaining to the field of the present disclosure. This section may include certain aspects of the art that may be related to various features of the present disclosure. However, it should be appreciated that this section is used only to enhance the understanding of the reader with respect to the present disclosure, and not as admissions of the prior art.
[0003] In recent years, concerns over personal safety, particularly for women, have heightened globally. Women face unique safety challenges in various environments, from urban settings to isolated areas, making personal security a critical issue that demands innovative solutions. Despite advances in technology, there remains a pressing need for effective and convenient safety devices that address both prevention and post-incident requirements. Traditional personal safety devices such as pepper sprays, standalone tasers, and basic alarms have served as the primary tools for immediate self-defence. These devices are effective in deterring immediate threats but present several limitations. For instance, pepper spray and standalone tasers are largely single-use or short-range tools that lack advanced features for incident documentation or broader situational awareness. Additionally, they provide no means of collecting evidence, which is essential for legal accountability and follow-up in the aftermath of an incident. Furthermore, these conventional devices offer no way to alert emergency contacts or authorities automatically, leaving users to rely solely on immediate deterrence without comprehensive support systems. To address varied safety needs, many users find themselves carrying multiple devices, such as a combination of pepper spray, a separate audio or video recorder, and even a personal alarm. This reliance on multiple devices not only creates inconvenience but can also reduce response efficiency in a high-stress situation, where quick action and ease of use are paramount. Existing technologies also often fall short in ergonomic design, making them cumbersome or impractical for daily use. Consequently, traditional safety devices do not provide an integrated, user-friendly solution for personal safety, evidence collection, and emergency alerting. To overcome the aforementioned challenges, there is a growing demand for a comprehensive personal safety device that combines self-defence mechanisms with advanced evidence collection and automated alert functionalities.
[0004] There is, therefore, a need in the art to provide a smart safety device and method that can overcome the shortcomings of the existing prior arts.

[00021] An aspect of the present disclosure relates to a smart safety device is designed for quick response in emergencies, with multiple integrated features for protection and evidence collection. Fingerprint Authentication on a capacitive biometric sensor verifies the authorized user's identity against pre-stored profiles via a mobile app or internal memory. Upon successful authentication, a servo motor rotates to unlock the pepper spray nozzle; if authentication fails, the motor remains locked, blocking spray access. When activated, the device's nozzle dispenses a potent Oleoresin Capsicum (OC), and CS (2-Chlorobenzalmalononitrile) mix to incapacitate attackers.

LED Indicators display battery and spray levels, and a USB-C Port enables convenient recharging. Further, in critical situations, a loud alarm alerts bystanders, and the device automatically sends the user's location to the nearest police station upon pepper spray activation, ensuring prompt assistance. The device ergonomic design provides a secure grip, making it a robust tool for personal safety, self-defence, and evidence collection.
