Bicycle Anti-theft Fork Locking System with Remote Actuation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anti-theft systems for bicycles, such as key-based and manual code locks, are not suitable for shared cycling systems as they lack personalized and simplified locking/unlocking mechanisms, and often require modifications to the bike frame and handlebars.
Innovation Solution
A bicycle with a fork lock system that includes a fork lock member and an anti-theft system with a locking member that can be remotely controlled, allowing for secure locking and unlocking using a secret code or RFID, ensuring only authorized users can access the bike.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a key-operated lock is used, then the anti-theft function is provided, but the key could be lost and it is not compatible with bike-sharing systems
Solution Approach 1:
The patent replaces the mechanical key-operated locking system with an electronic control system. The electronic control unit receives unlocking signals and automatically actuates the locking device via an actuator, eliminating the need for physical keys and enabling remote operation through communication interfaces.
Solution Approach 2:
The locking device is designed to automatically lock the fork when the bicycle is stolen or left unattended. The system self-activates without requiring user intervention, and the electronic control unit manages the locking/unlocking process automatically based on received signals.
2Reliability
If a manual code lock is used, then the locking function is provided, but the user must remember the code and it is not advantageous for cycle-sharing systems
Solution Approach 1:
The patent replaces the manual code-based mechanical locking system with an electronic control system that processes unlocking signals through a communication interface. This eliminates the need for users to remember codes while maintaining secure locking functionality through electronic authentication.
3Reliability
If existing anti-theft locks are installed, then the locking function is provided, but a hole must be made in the frame and handlebars
Solution Approach 1:
The patent separates the locking function from the frame structure by using a detachable locking device that engages with the fork rather than requiring permanent modifications to the frame. The locking device can be independently installed and removed without altering the bicycle's structural integrity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables secure, personalized, and simplified locking and unlocking of bicycles in shared systems, preventing unauthorized access while maintaining the integrity of the bike's structure.
Implementation Method 1
The locking element is elastically forced towards the first position
Implementation Method 2
a bellows controlled by the actuator, an elastically pivoting cam

AI summary
A bicycle (12) comprising an anti-theft lock (100) including a fork locking member (104) fixed to the fork (20) of the bicycle (12) having an opening (106), and an anti-theft system (102) mounted to the frame (18) of the bicycle (12). The anti-theft system (102) has a locking member (110) movable between a first position where the locking member (110) is separated from the opening (106) of the fork locking member (104) and the anti-theft lock (100) is in the unlocked position, and a second position where the locking member (110) cooperates with the opening (106) of the fork locking member (104) and the anti-theft lock (100) is in the locked position. When the anti-theft lock (100) is in the locked position, the fork (20) is locked in a rotated position of the front wheel (16).
