Solution Overview
Problem
Traditional door locks are insecure, requiring users to carry keys or key cards and remember PINs, and are vulnerable to unauthorized access, with individual configuration being time-consuming and laborious in hotels and resorts.
Innovation Solution
A digital biometric door lock system incorporating a fingerprint scanner and key card slot, with central software for configuring and authenticating registered fingerprint and access code samples, eliminating the need for physical keys and PINs, and allowing central network integration for secure access management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional key or key card-based locks are used, then access can be granted to individuals possessing the key or key card, but security is compromised because anyone in possession of the instrumentality of access can gain unauthorized entry
Solution Approach 1:
The patent replaces mechanical key-based locking systems with a digital biometric authentication system. The mechanical key is substituted with a fingerprint scanner that uses optical or capacitive sensing to capture and verify fingerprint patterns. This substitution eliminates the ability of unauthorized individuals to gain access through physical duplication of keys or key cards, as biometric fingerprints are unique to each individual.
Solution Approach 2:
The patent creates a digital copy of the fingerprint pattern and stores it in a database for comparison. Instead of relying on physical keys that can be copied, the system creates a digital representation of the biometric data and compares it during authentication. This digital copying approach ensures that even if the physical fingerprint scanner is accessed, the unique biometric template cannot be replicated to gain unauthorized access.
2Ease of operation
If keypad-based locks with PIN codes are used, then access control is implemented, but individuals must remember the access code which increases cognitive load and security risks when using multiple services
Solution Approach 1:
The fingerprint authentication system performs self-service verification without requiring the user to remember or input any codes. The system automatically captures the fingerprint, compares it against stored templates, and grants or denies access based on the match. This eliminates the cognitive burden of remembering PIN codes across multiple services while maintaining secure access control.
3Reliability
If standard door locks are used, then access restriction is achieved, but the locks can be easily picked or broken, leading to intrusion and potential injury or theft
Solution Approach 1:
The patent replaces traditional mechanical locks with a digital biometric authentication system. The mechanical locking mechanism is substituted with an electronic system that uses a fingerprint scanner, microcontroller, and motor-driven latch. This substitution provides superior security as the system can detect and respond to unauthorized access attempts, and the biometric verification cannot be bypassed by picking or breaking the physical lock mechanism.
4Adaptability or versatility
If individual lock configuration is performed in hotels and resorts, then access control is customized, but the process is time-consuming and laborious
Solution Approach 1:
The patent implements a universal access control system that can serve multiple functions across different locations. The same fingerprint authentication module can be deployed in hotels, resorts, and other facilities, eliminating the need for separate configuration processes for each location. The system can be centrally managed and configured, allowing administrators to set up access controls remotely without visiting each location, thus reducing time and labor requirements.
