Solution Overview

Problem

Existing electric vehicle batteries, particularly in pedal-assisted electric bikes, are vulnerable to theft and unauthorized use due to lack of effective security measures.

Innovation Solution

A battery system with integrated electronic processing means, including a microprocessor-based management and control unit, identification code storage, and radio-frequency communication, which allows for secure activation and deactivation, theft detection, and remote monitoring, using a single container design that can be easily integrated into the bike frame.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional battery designs are used without integrated security systems, then the battery structure remains simple and cost-effective, but the battery becomes vulnerable to theft and unauthorized use

Engineering Contradiction:
Improvesecurity against theft and unauthorized useVSAvoidbattery structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the battery, electronic processing means, and security system into a single integrated battery unit. The control unit and communication interface are housed within the same container as the battery cells, eliminating the need for separate security devices and reducing overall system complexity while maintaining security functionality.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The battery control unit serves multiple functions: it manages battery charging/discharging operations, implements security authentication through the communication interface, and enables theft prevention. This multi-functional approach eliminates the need for separate dedicated security devices, resolving the contradiction between security reliability and device complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If advanced security systems with multiple components are implemented, then theft detection and prevention capabilities improve, but the cost and complexity of the battery system increase

Engineering Contradiction:
Improvetheft detection and prevention capabilityVSAvoidmanufacturing simplicity and cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The security system components (control unit, communication interface, authentication logic) are integrated into the existing battery management infrastructure rather than being implemented as separate add-on components. This reduces the total component count and simplifies manufacturing processes while maintaining advanced theft detection and prevention capabilities.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The battery system performs security authentication and theft detection functions autonomously through its integrated control unit and communication interface, eliminating the need for external security devices or complex installation procedures. This self-service approach reduces manufacturing complexity and cost while providing reliable security functionality.

Inventive Principle:
Principle #25Self-service
