EXTENDABLE BLIND STICK WITH SOS FUNCTIONALITY

Abstract

The present invention relates to an extendable walking stick designed for visually impaired individuals, equipped with an emergency SOS feature. The stick consists of a retractable body that can extend from a compact form to a longer, more suitable length upon pressing a designated button. It includes a handgrip with an embedded SOS button that, when pressed three times, sends a distress signal to a caretaker or emergency contact. The system utilizes a microcontroller to process the input and activate a communication module, which can connect via GSM, Bluetooth, or Wi-Fi. The distress signal, containing the user’s GPS location, is transmitted through either direct messaging or by linking with a smartphone. Upon successful signal transmission, the user receives vibration feedback. The walking stick provides both enhanced mobility through its extendable feature and critical emergency support, ensuring safety and independence for visually impaired individuals.

Specification

Description:The extendable blind stick consists of several key components that enhance its functionality.
The body of the stick (102) is made from lightweight materials such as aluminium or carbon
fiber, ensuring that it is both durable and easy to carry. The length of the stick can be adjusted
from a compact state of around 90 cm to an extended length of up to 150 cm, providing
versatility for various walking conditions. The hand grip (202) is designed using soft, non-slip
materials like rubber or silicone, ensuring that it is both comfortable and easy to hold for
extended periods. This grip houses two critical buttons: the extension mechanism button
(101,201) and the SOS button (104,203). , Claims:1. A walking stick (100) for visually impaired individuals, comprising: (i) A mechanism to
extend the body (101,201), (ii) An SOS button (104,203);
2. A walking stick (100) of claim 1, comprising a retractable body capable of extending from
a compact state (200) to an extended state (100) upon activation of a button (101,201);
3. A walking stick (100) of claim 1, wherein the body (102) is constructed from lightweight,
durable materials such as aluminium or carbon fiber, with an extendable range between 90
cm and 150 cm;
4. A walking stick (100) of claim 1, further comprising an SOS feature, wherein an SOS button
(104, 203) is located on the hand grip (202), which, when pressed three times, activates a
wireless communication module to send a distress signal to a designated contact such as a
caretaker or doctor;
5. A walking stick (100) of claim 1, wherein the extension mechanism is powered by a spring-
loaded system, allowing smooth and automatic transition between compact (200) and
extended (100) states; and
6. A walking stick (100) of claim 1 and claim 4, further comprising a vibration-based feedback
system to confirm successful activation of the SOS function.
