Description:FIELD OF THE INVENTION
This invention relates to design and implementation of a secure automated garage system.
BACKGROUND OF THE INVENTION
Manually operated garage systems are inconvenient, less secure, and lack modern accessibility and smart features. They require physical effort, making them difficult for certain users, especially in bad weather conditions. The disadvantages of traditionally manual operated garage systems require:
Physical Effort
• Manually opening and closing a garage door requires users to step out of their vehicle, which can be especially troublesome in extreme weather conditions (rain, snow, or heat).
• If the garage door is heavy, it may require significant effort to lift and close, causing inconvenience for elderly users or individuals with physical limitations.
• In situations where a user is in a hurry, stopping to open or close the garage door manually can be frustrating and time-consuming.
Prone to Security Vulnerabilities
• Traditional garage doors often rely on mechanical locks, which can be easily picked or forced open by burglars.
• If the key to a manual garage door is lost or stolen, the security risk increases, as an intruder can potentially gain easy entry.
• Manual doors may not provide alert systems or monitoring capabilities, preventing real-time security updates.
Limited Accessibility and User-Friendliness
• Individuals with mobility issues, elderly users, or people carrying heavy items may struggle to operate a manual garage door.
Increased Wear and Tear
• The mechanical components of a manually operated garage system, such as hinges, locks, and springs, experience more physical stress due to frequent direct handling.
• Improper usage, such as slamming the door shut or excessive force while lifting, can damage the system, requiring frequent maintenance.
• Regular service is needed to ensure smooth operation, leading to additional maintenance costs over time.
Traditional locks are more vulnerable to break-ins, increasing security risks. Frequent use leads to faster wear and tear of mechanical components, requiring more maintenance. Additionally, the absence of remote control and smart technology limits convenience and efficiency. So, there is a dire need to develop an automated garage system.
EXISTING SOLUTIONS / PRIOR ART/RELATED APPLICATIONS & PATENTS
A. Password-Based Door Lock System
Password-based door lock system is an electronic security system that uses a predefined password or PIN code to control access. It is implemented using a microcontroller, a keypad, and an electronic lock. When a user enters the correct password, the system unlocks the door; otherwise, access is denied.
Drawbacks of this system are:
1. Risk of Password Theft – If someone sees or overhears the password, unauthorized access becomes easy.
2. Lack of Multi-Factor Authentication (MFA) – Unlike biometric or smart card-based systems, this method relies solely on a single authentication factor.
3. Limited Security Against Hacking – If connected to a digital system, it may be vulnerable to hacking or electronic tampering.
4. Physical Damage to Keypad – If the keypad is damaged due to wear and tear or vandalism, the system may fail.
B. Password Enabled Door Locking System Using Arduino and IoT:
Password Enabled Door Locking System using Arduino and IoT is security system integrating password-based authentication with Internet of Things (IoT). This system enhances traditional password-based locks by allowing remote monitoring and control through a web interface or a mobile app.
Drawback of this system are:
1. Hacking Risks – IoT-based systems can be vulnerable to cyber-attacks if not properly secured.
2. Password Vulnerability – If the password is weak or shared, unauthorized access becomes a risk.
3. Hardware Failures – Components like Wi-Fi modules, keypads, or servo motors can malfunction over time.
4. Complexity in Setup and Maintenance – Compared to a simple password-based lock, IoT integration requires technical knowledge for setup and troubleshooting.
Password-Based Door Lock Systems and Password-Enabled Door Locking Systems Using Arduino and IoT provide basic security and access control but fall short in achieving a fully automated garage system due to several limitations like:
1. Lack of Automatic Vehicle Detection
• These systems rely on a user entering a password manually via a keypad or an app. They do not detect an approaching vehicle automatically.
2. No Hands-Free Access
• Users must physically enter a password on a keypad or mobile app, which is inconvenient while driving.
3. Security Risks (Hacking & Password Theft)
• Passwords can be stolen, shared, or hacked (especially in IoT-based solutions). If an attacker gains access to the Wi-Fi network, they could potentially control the door.
4. No Real-Time Obstacle Detection & Safety Measures
• These systems do not have safety mechanisms to detect obstacles (people, pets, or vehicles) in the garage door’s path.
There requires a fully automated garage system which does vehicle detection, hands-free authentication, security enhancements, smart automation, real-time obstacle detection, and offline capabilities.
