Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electrically powered vehicles, such as electric bicycles and motorcycles, face high theft rates due to the vulnerability of their energy storage devices, despite mechanical security measures, which can be easily overcome with sufficient knowledge and tools.
Innovation Solution
An electronic energy storage security module is integrated into the vehicle, storing an energy storage security key that can be read by the vehicle, allowing it to be registered as stolen and triggering an alarm mode if unauthorized use is detected, with additional features like restricted operation and tracking signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mechanical security measures (locks, locks) are used to secure energy storage devices in vehicles, then the devices can be physically protected, but they can still be overcome with sufficient knowledge, skill and tools within a reasonable time
Solution Approach 1:
The patent replaces mechanical security measures with an electronic identification and verification system. The energy storage device contains an electronic identification code that must be verified by the vehicle's control unit, substituting physical locks with an electronic authentication mechanism that prevents unauthorized use without relying on mechanical barriers.
Solution Approach 2:
The patent introduces an intermediary verification process between the energy storage device and the vehicle's power supply system. The control unit acts as an intermediary that checks the identification code before enabling power transfer, creating a security barrier that cannot be bypassed by mechanical means alone.
2Reliability
If electronic identification codes are used in vehicles and batteries to prevent unauthorized use, then security is improved, but the system requires reading and verifying codes which adds operational steps
Solution Approach 1:
The system performs automatic identification and verification without requiring user intervention. When the energy storage device is connected to the vehicle, the control unit automatically reads the identification code and verifies it against stored codes, enabling or disabling power supply without the user needing to manually enter codes or perform verification steps.
Solution Approach 2:
The valid identification codes are pre-stored in the vehicle's control unit memory before operation. This preliminary preparation allows for instant verification during connection, eliminating the need for real-time code entry or complex verification procedures by the user.
3Ease of manufacture
If accumulators are made replaceable or removably attached for maintenance and charging, then maintenance convenience is improved, but the risk of theft increases due to easy removal
Solution Approach 1:
The patent replaces mechanical security (physical attachment strength) with electronic security (identification verification). The connector provides sufficient mechanical retention for normal use and maintenance, while the electronic verification system prevents unauthorized removal and use, allowing easy legitimate access while blocking theft.
Solution Approach 2:
The security function is localized to the electronic identification and verification system within the connector and control unit, while the mechanical connector maintains its primary function of electrical and mechanical connection. This separation allows the mechanical design to focus on ease of attachment while the electronic system handles security.
