Solution Overview

Problem

Personal transportation devices such as bicycles are prone to theft due to inadequate locking mechanisms, often using low-quality locks that are easily compromised, necessitating the need for high-security, user-specific, and easy-to-use locking solutions.

Innovation Solution

A locking device featuring a biometric reader, securing ring, and wireless communication capabilities that allows secure attachment to external structures, utilizing a clamping head and hinge mechanism for versatile mounting, with a control unit to activate or deactivate the lock based on user authentication and proximity detection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If high-quality locking mechanisms are used to prevent theft, then security is improved, but device complexity and cost increase

Engineering Contradiction:
Improvetheft preventionVSAvoidlocking mechanism complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces traditional mechanical locking systems with an electromechanical system that uses an electric motor to rotate a spool, which winds or unwinds a cable to clamp or release the personal transportation device. This substitution allows for more reliable and controllable locking while enabling integration with electronic authentication mechanisms.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces a control unit as an intermediary between the biometric authentication system and the locking mechanism. The control unit receives biometric data from the sensor, processes it to determine authentication success, and accordingly activates or deactivates the motor to engage or disengage the lock, providing a coordinated response that integrates multiple functions.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If biometric authentication is implemented, then user-specific security is improved, but device complexity increases

Engineering Contradiction:
Improveuser authenticationVSAvoidauthentication system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces traditional mechanical key-based authentication with a biometric authentication system using fingerprint or other biological identifiers. This provides more reliable user-specific security while eliminating the need for physical keys that can be lost or duplicated.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The biometric authentication system enables users to authenticate themselves automatically without requiring manual key handling or complex procedures. The sensor captures biometric data and the control unit processes it autonomously to determine whether to engage the locking mechanism, making the authentication process seamless and user-friendly.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If automated locking mechanisms are used, then ease of operation is improved, but device complexity increases

Engineering Contradiction:
Improvelocking operationVSAvoidautomation system complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The automated locking mechanism performs the locking and unlocking actions autonomously based on biometric authentication results. When a user successfully authenticates, the control unit automatically activates the motor to release the cable clamp, and when authentication fails or the device is stolen, it automatically engages the lock without requiring manual intervention.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system incorporates feedback through the biometric sensor that continuously monitors for the presence of authorized users and detects authentication status. This feedback loop allows the control unit to automatically adjust the locking state based on real-time biometric data, enabling hands-free operation and improving ease of use while maintaining security.

Inventive Principle:
Principle #23Feedback
