Digital Key Personalization for Temporary Vehicle Drivers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle systems struggle to accommodate temporary drivers by storing personal setting information in the vehicle, leading to inconvenience and increased risk of accidents when substitute drivers or valet drivers adjust settings without owner consent.
Innovation Solution
A vehicle system that stores personal preference settings in a digital key, allowing temporary drivers to access personalized vehicle functions via the key, and automatically reverts to owner settings upon temporary driving termination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If personal setting information is stored in the vehicle, then the vehicle owner can access personalized settings, but temporary drivers cannot access their own personalized settings and the owner's settings may be accidentally modified
Solution Approach 1:
The patent segments the settings storage and access control by separating owner settings and temporary driver settings into different storage locations within the digital key system. Each digital key contains its own personalized settings, allowing the owner and temporary drivers to access their respective settings independently without interfering with each other, thus resolving the contradiction between personalized access and settings security
Solution Approach 2:
The digital key acts as an intermediary that carries personalized settings from the user to the vehicle. Instead of storing settings directly in the vehicle, the digital key mediates the transfer of settings information, enabling temporary drivers to access their own settings while preventing unauthorized modification of the owner's settings stored in their separate digital key
2Adaptability or versatility
If the vehicle stores multiple users' settings, then temporary drivers can access personalized settings, but the system complexity increases
Solution Approach 1:
The patent extracts the settings storage function from the vehicle's central system and relocates it to individual digital keys. Each digital key independently stores its own personalized settings, eliminating the need for a complex vehicle-side multi-user settings management system while still enabling temporary drivers to access their personalized settings
Solution Approach 2:
The settings are copied into each user's digital key rather than being centrally stored in the vehicle. This allows multiple users to have identical copies of their personalized settings in their respective digital keys, simplifying the vehicle's system architecture while maintaining multi-user functionality
3Ease of operation
If temporary drivers use the vehicle with modified settings, then they can drive comfortably, but the owner experiences inconvenience when retrieving the vehicle
Solution Approach 1:
The patent applies preliminary action by automatically restoring the owner's settings before the owner retrieves the vehicle. The system detects when the digital key is removed or when the vehicle is locked, and automatically reverts all settings to the owner's original configuration, ensuring the owner always finds the vehicle in their preferred state without manual intervention
