Solution Overview

Problem

Existing smart locking systems and bicycle-sharing systems lack flexibility and security, with rented bicycles often in poor condition and requiring modifications to infrastructure for installation, and users face risks using shared bicycles.

Innovation Solution

A retrofittable smart lock that attaches to existing bicycle racks, using a smartphone for operation, with no internet connection required, featuring a hardened steel body, rechargeable batteries, and unique cryptographic keys, ensuring security and durability without external keyholes or interfaces.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If smart locks are integrated into existing bicycle racks, then adaptability and ease of installation are improved, but device complexity increases

Engineering Contradiction:

Improveadaptability to existing bicycle racksVSAvoidcomplexity of smart lock system

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The smart lock system is divided into separate functional modules: the locking mechanism, the control unit, the power supply (rechargeable battery), and the communication interface. This segmentation allows each component to be optimized independently and facilitates installation on existing bicycle racks without requiring complete system replacement.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The smart lock is designed with universal mounting capabilities that accommodate various bicycle rack types and configurations. The device can function as both a traditional lock and a smart-controlled lock, providing multiple locking modes and compatibility with different authentication methods (cryptographic keys, mobile applications).

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If cryptographic keys are used for authentication, then security is improved, but ease of operation deteriorates

Engineering Contradiction:

Improvesecurity of locking mechanismVSAvoidease of unlocking operation

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The traditional mechanical key system is replaced with cryptographic keys implemented through mobile applications and wireless communication protocols. This substitution provides enhanced security through cryptographic authentication while maintaining ease of operation via touchscreen interfaces and automatic authentication processes.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

A mobile application serves as an intermediary between the user and the smart lock system. The application handles cryptographic key generation, storage, and authentication processes, thereby securing the locking mechanism while simplifying user interaction through an intuitive graphical interface that abstracts away the cryptographic complexity.

Inventive Principle:

Principle #24Intermediary (Mediator)
