Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional bicycle anti-theft methods are cumbersome, prone to locking issues due to lost keys or forgotten passwords, and require manual adjustments for different rider sizes, which are inconvenient and can lead to sports injuries.

Innovation Solution

An anti-theft apparatus for bicycles that incorporates a biometric feature identification device, a brake lever, a brake, and a control device, which uses biometric features like fingerprints or vocal prints to lock the bicycle when the brake lever is pressed, ensuring secure and convenient use by only allowing authorized users to operate and adjust the bike.

Engineering Contradictions & Design Principles

VSEngineering 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 are bulky, dirty, inconvenient to carry, and may become unusable if keys are lost or passwords are forgotten

Engineering Contradiction:

Improveanti-theft securityVSAvoidconvenience of use

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces conventional mechanical locking systems (chains, steel locks, mechanical locks) with an electronic control system that uses biometric identification (fingerprint sensors) and electronic actuators to lock and unlock the bicycle. The brake lever position sensor and control unit eliminate the need for physical keys or passwords, resolving the contradiction between security and convenience.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system enables the bicycle to automatically identify the user through fingerprint recognition and automatically lock/unlock based on authentication results. The bicycle serves itself by comparing stored biometric data with input data and executing locking actions without requiring manual intervention with keys or passwords.

Inventive Principle:

Principle #25Self-service

2Adaptability or versatility

If manual adjustment of bicycle parts (saddle height, stem/handlebar height) is performed, then the bicycle can be adapted to different riders, but the adjustments require experience, manual effort, and repeated back-and-forth adjustments to achieve desired results

Engineering Contradiction:

Improveadaptability to different ridersVSAvoidease of adjustment

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent replaces manual mechanical adjustment of bicycle parts with an automated electronic control system. The control unit receives input from the biometric identification device and automatically adjusts saddle height, stem/handlebar height, and other components using electric actuators, eliminating the need for experienced manual adjustment and repeated trial-and-error.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system performs preliminary actions by pre-storing biometric data and corresponding optimal adjustment parameters for different users. When a user authenticates, the system automatically retrieves and applies the pre-determined adjustment settings, eliminating the need for real-time manual adjustment and repeated modifications.

Inventive Principle:

Principle #10Preliminary action
