Digital Vehicle Key Duplication for Multi-Device Registration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The process of registering multiple friend devices as keys for a vehicle in a wireless digital key system is cumbersome and inefficient, particularly when using the Car Connectivity Consortium standard.
Innovation Solution
An information processing device that allows users to select and duplicate key information from an owner device to additional terminals, enabling them to function as vehicle keys, thereby simplifying the registration process by allowing batch addition of friend devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If friend devices are registered one at a time according to CCC standard, then each device can be properly authenticated and configured, but the registration process becomes effortful and time-consuming for users
Solution Approach 1:
The system performs preliminary actions by automatically detecting available friend devices and pre-configuring duplication settings before the user finalizes registration. The owner device proactively identifies connected devices and prepares duplication parameters, reducing the effort required during actual registration while maintaining security through user confirmation.
Solution Approach 2:
The system creates copies of key information from the owner device to friend devices through automated duplication processing. Instead of requiring separate configuration for each friend device, the system copies authentication data and vehicle access parameters, ensuring consistent reliability while dramatically simplifying the registration process.
2Productivity
If multiple friend devices are registered simultaneously, then the registration process becomes faster and less effortful, but the system complexity and potential for errors increase
Solution Approach 1:
The system segments the multi-device registration process into independent duplication tasks that can be executed simultaneously. Each friend device receives individual duplication processing with dedicated authentication sequences, allowing parallel registration while maintaining system manageability through modular task execution.
Solution Approach 2:
The registration system implements universal processing capabilities that handle multiple friend devices through a single integrated interface. The owner device performs multiple functions including device detection, user selection reception, and simultaneous duplication execution, reducing overall system complexity while enabling batch registration.
3Ease of operation
If automated duplication processing is implemented for multiple devices, then user effort is reduced, but the need for user selection and confirmation steps increases interface complexity
Solution Approach 1:
The system implements self-service capabilities by automatically detecting connected friend devices and preparing duplication configurations without requiring detailed user input. The owner device autonomously identifies available devices, retrieves their information, and presents pre-configured options for user confirmation, reducing user effort while maintaining necessary control.
Solution Approach 2:
The system incorporates feedback mechanisms that display detected friend devices and duplication status to the user in real-time. The interface provides visual confirmation of selected devices and processing progress, allowing users to monitor and control the automated process without being overwhelmed by complexity.

AI summary
An information processing device that is usable as a key of a vehicle, the information processing device including: a display section that is configured to display information of at least one other device that is connected to the information processing device; a memory; and a processor coupled to the memory and that is configured to: receive a user selection selecting, from the at least one other device displayed at the display section, at least one other device to be operated as a key of the vehicle; and execute duplication processing to each of the selected at least one other device to allow the selected at least one other device to be used as the key of the vehicle.
