Bicycle Smart Lock With Fingerprint Access and Backup Power
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cycle locking systems, such as mechanical, combination, and smart locks, face issues with reliability, ease of use, and response time, particularly in shared bicycle systems, where mechanical locks are prone to loss and combination locks are slow and unreliable, and smart locks may fail due to network issues.
Innovation Solution
A smart lock system with a fingerprint recognition system, integrated timer, and a cascading power supply using solar, internal, and external power sources, enabling secure, fast user identification and authorization, with encrypted fingerprint data storage and location tracking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mechanical lock with key is used, then the locking function is simple and reliable, but keys can be lost or forgotten and mechanical locks can be opened without a key relatively easily
Solution Approach 1:
The patent replaces the mechanical key-based locking system with a biometric fingerprint recognition system. The fingerprint reader captures fingerprint images, extracts features, and compares them against stored templates to authenticate users, eliminating the need for physical keys and their associated problems of loss, forgetting, or easy duplication.
Solution Approach 2:
The system creates digital copies of fingerprint patterns as biometric templates stored in a database. These fingerprint templates serve as unique identifiers for authentication, replacing physical keys with digital biometric data that cannot be lost or forgotten.
2Ease of operation
If a combination lock is used, then the lock can be opened without a key, but the number combination needs to be altered to keep the lock closed and the code can be forgotten
Solution Approach 1:
The patent replaces the combination-based mechanical locking system with a biometric fingerprint recognition system. Instead of relying on user-remembered numerical codes that can be forgotten or compromised, the system uses automated fingerprint capture, feature extraction, and template matching to provide reliable and convenient access.
3Ease of operation
If a smart password lock with mobile device is used, then the lock can be unlocked electronically, but it may malfunction if the mobile device has a malfunction or network signal is insufficient, and unlocking can take 10 seconds and longer
Solution Approach 1:
The patent replaces mobile device-based authentication with direct fingerprint capture at the lock. The fingerprint reader is integrated into the locking mechanism, eliminating dependence on external mobile devices, network connectivity, and power management of separate devices, thereby providing faster and more reliable access.
Solution Approach 2:
The system introduces a local biometric authentication intermediary (the fingerprint reader and recognition system) that operates independently of external network infrastructure. This intermediary enables direct local verification of user identity without requiring communication with remote servers, ensuring access reliability even when network signals are insufficient.
4Adaptability or versatility
If a smart lock system with network communication is used, then remote access control is enabled, but network traffic can cause delays of 10 seconds and longer in unlocking
Solution Approach 1:
The system performs preliminary actions by capturing and storing fingerprint templates in advance during the enrollment process. During authentication, the system compares the captured fingerprint against pre-stored templates locally, eliminating the need for real-time network communication during the actual unlocking process and thus reducing waiting time.
Solution Approach 2:
The patent introduces a local biometric authentication intermediary that operates independently of external network infrastructure. This intermediary enables direct local verification of user identity without requiring communication with remote servers, ensuring fast access while maintaining the capability for remote management through periodic synchronization.
