Electronic Key System Unique Registrant Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic key systems face interference and authentication failures due to the registration of identical information in multiple mobile devices, leading to issues when new devices are integrated without pre-registered vehicle identification information and response timing.
Innovation Solution
An electronic key system that generates new main identification information each time registration is performed, ensuring unique registrant identification information for each mobile device, preventing simultaneous transmission of mobile device codes during authentication and reducing interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the same vehicle identification information and response timing are registered in multiple mobile devices, then multiple devices can function as electronic keys, but authentication interference occurs and authentication processing fails
Solution Approach 1:
The patent segments the identification information by creating device-specific response timing values for each mobile device. Instead of using identical vehicle identification information across all devices, the system divides the authentication parameters into vehicle-specific identifiers and device-specific timing parameters, allowing multiple devices to coexist without interference
Solution Approach 2:
The patent applies local quality by assigning unique response timing characteristics to each mobile device while maintaining the common vehicle identification information. Each mobile device receives customized response timing values that are specific to that device, creating local differentiation within the global system
2Device complexity
If fixed-value identification information is used for authentication, then authentication processing is simple, but new mobile devices cannot be registered without causing interference with existing devices
Solution Approach 1:
The patent introduces dynamics by making response timing information variable and device-specific rather than fixed. The system dynamically assigns different response timing values to different mobile devices, allowing the authentication parameters to adapt to each device while maintaining a relatively simple authentication process
Solution Approach 2:
The patent changes the authentication parameters by introducing device-specific response timing values that differ from the fixed vehicle identification information. This parameter differentiation allows multiple devices to be registered with the same vehicle identifier while maintaining unique authentication characteristics for each device

AI summary
An electronic key system includes a mobile device and a control device. Main identification information identifying the control device is registered in the control device as registrant identification information. When the mobile device receives a response request including the registrant identification information and response timing, the mobile device compares the registrant identification information and the response timing which included in the response request with registrant identification information and response timing registered in the mobile device. When a result of the comparing is a match, the mobile device transmits the mobile device code to the control device. The control device includes a registration unit that newly generates the main identification information with different content each time a registration command is inputted, and registers the newly generated main identification information in a storage device of the control device as registrant identification information.
