Bicycle On-board System Component Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bicycles with electric systems face theft issues due to the compatibility of electrical components, allowing stolen parts to be resold, and existing theft prevention methods are inadequate in preventing unauthorized use or resale.
Innovation Solution
An on-board system where electrical components are individually identified and authenticated, with functionality varying based on matching authentication information stored on the bicycle, restricting or augmenting functionality if the components do not match, thereby deterring theft without requiring network communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If electrical components are made compatible and detachable for user convenience, then ease of operation and adaptability improve, but theft risk increases because stolen components can be resold
Solution Approach 1:
The system performs preliminary authentication of electrical components before allowing them to function. Each component has a unique identification information that is verified against stored authentication information in the control unit before the component is permitted to operate, preventing theft without restricting legitimate use
Solution Approach 2:
The system continuously monitors and verifies component authentication status. The control unit receives feedback from authentication information storage and compares it with current component identification, providing real-time verification that prevents unauthorized components from functioning while maintaining system security
2Reliability
If existing theft prevention methods are used, then theft detection improves, but functionality is not effectively restricted for stolen components
Solution Approach 1:
The system takes preliminary anti-action by preventing stolen components from functioning in the first place. Instead of detecting theft after it occurs, the authentication mechanism blocks unauthorized components before they can be used, effectively restricting harmful factors at the source
Solution Approach 2:
The system extracts and stores unique authentication information for each electrical component in the control unit. This extracted authentication data is then used to verify component legitimacy, separating the authentication function from the component operation itself to enable effective theft prevention

AI summary
An on-board system includes electrical components mounted on a bicycle that have been individually identified. Each of the electrical components performs some functionality of the bicycle. At least one of the electrical components is detachable from the bicycle. The electrical components, when mounted on the bicycle, are electrically connected to each other. At least one of the electrical components includes a storage to store individual identification information about an authenticated electrical component. The functionality of the bicycle implementable by at least one of the electrical components mounted on the bicycle that have been individually identified varies depending on whether a combination of the individually identified electrical components matches the individual identification information about the authenticated electrical components stored in the storage.
