Car Key Credential Transfer During Device Setup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques for managing car key credentials on electronic devices are cumbersome and inefficient, requiring complex user interfaces with multiple key presses and consuming excessive time and device energy, particularly in battery-operated devices.
Innovation Solution
A method and interface for efficiently managing car key credentials through a streamlined process involving a computer system that receives credential information from a second system, reducing the need for redundant user inputs and optimizing power usage.

Engineering Contradiction Analysis
1Ease of operation
If existing techniques are used to manage car key credentials, then the credential provisioning process can be completed, but the process becomes complex and time-consuming requiring multiple key presses
Solution Approach 1:
The system performs preliminary actions by automatically initiating the credential provisioning process when a second computer system is detected near the vehicle. The second system's credentials are pre-validated and ready for transfer, eliminating the need for users to manually navigate through multiple setup steps and key presses during the actual provisioning moment.
Solution Approach 2:
The second computer system acts as an intermediary that bridges the credential transfer between the user and the vehicle. Instead of direct complex interaction between the user and vehicle systems, the second system mediates by providing its authenticated credentials to the vehicle, which then provisions the first computer system with authorized access.
2Reliability
If existing techniques are used to manage car key credentials, then the credential provisioning process can be completed, but excessive device energy is consumed
Solution Approach 1:
The system implements self-service by automatically detecting the presence of the second computer system and initiating the credential provisioning process without requiring the first computer system to actively search or request credentials. The second system automatically offers its credentials, and the vehicle system automatically processes the provisioning, minimizing active processing and energy consumption.
Solution Approach 2:
The system uses periodic action by implementing event-driven triggers that activate credential provisioning only when specific conditions are met (such as detection of a second system with valid credentials). This prevents continuous scanning or polling operations that would consume excessive battery power while ensuring reliable provisioning when needed.
3Productivity
If a streamlined process is implemented for credential management, then user time and device energy are conserved, but the process requires coordination between multiple systems
Solution Approach 1:
The system applies universality by designing the credential provisioning mechanism to work across multiple computer systems and vehicle platforms through standardized protocols. The same core logic handles credential validation, transfer, and provisioning regardless of which specific second system initiates the process or which vehicle model receives the credentials, reducing the need for system-specific complex coordination logic.
