Bicycle Brake Lever Biometric Locking and Auto-Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bicycle anti-theft methods are cumbersome and inconvenient, often requiring manual adjustments for riders of different sizes, which can lead to sports injuries due to improper riding posture.
Innovation Solution
An apparatus and method integrating a biometric feature identification device, a brake lever, and a control device that locks the bicycle using biometric authentication and adjusts bicycle components based on user-specific parameters, ensuring secure locking and personalized fit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional locks (chains, steel locks, mechanical locks) are used for bicycle anti-theft, then the bicycle can be secured, but the locks become bulky, dirty, and inconvenient to carry
Solution Approach 1:
The patent combines the anti-theft locking function with the brake lever, which is a necessary component for bicycle operation. By integrating the locking mechanism into the existing brake lever structure, the system eliminates the need for separate external locks, thereby improving convenience while maintaining security functionality
Solution Approach 2:
The brake lever is designed to serve multiple functions: normal braking operation and anti-theft locking. When the brake lever is pressed to the preset position, it simultaneously engages the braking mechanism and activates the locking function through the fixing device, making the component universal and eliminating the need for dedicated locking tools
2Adaptability or versatility
If manual adjustment of bicycle parts is performed for riders of different body sizes, then the riding posture can be corrected, but the process requires experience and must be repeated back and forth several times
Solution Approach 1:
The system enables self-service adjustment by automatically identifying the rider through biometric recognition and autonomously adjusting the saddle and handlebar positions according to pre-stored parameters. This eliminates the need for manual intervention and repeated trial-and-error adjustments, allowing the bicycle to adapt to different riders independently
Solution Approach 2:
The biometric identification device provides feedback about which rider has mounted the bicycle, triggering the control device to retrieve and execute the corresponding adjustment parameters. This feedback mechanism ensures accurate and automatic customization for each rider without requiring manual input or experience
3Ease of operation
If biometric feature identification and automatic locking system is implemented, then convenience is improved, but device complexity increases
Solution Approach 1:
The control device leverages the existing brake lever mechanism to perform both braking and locking functions. By reusing the mechanical structure and integration points already present in the bicycle, the system minimizes the addition of complex external components while achieving multi-functionality
Solution Approach 2:
The fixing device is integrated into the brake lever assembly, combining the locking mechanism with the existing structural elements. This merging approach reduces the need for separate locking components and simplifies the overall system architecture despite the added biometric and control functionalities

AI summary
An apparatus and a method for bicycle anti-theft and personalized adjustment are provided. When a biometric feature of a user matches a preset biological feature, a brake lever is fixed at a preset position to lock the bicycle, and a variable structure is driven to make personalized adjustments according to bicycle adjustment parameters corresponding to the biometric feature of the user.
