Merging Navigation Changes from Multiple User Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current navigation systems in vehicles pose safety hazards and operational challenges when drivers attempt to make on-the-fly changes while driving, such as adjusting routes or inputting points of interest, due to the complexity and distraction involved in using these systems during vehicle operation.
Innovation Solution
A system that allows navigation changes to be made on both the vehicle's onboard navigation system and a user device, with communication between the two to merge changes, enabling passengers to input changes without distracting the driver, and allowing for session state saving and resuming in case of connection loss, supporting multiple users and devices, and integrating with cloud networks for data storage and retrieval.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If drivers make on-the-fly navigation changes while operating the vehicle, then navigation adaptability is improved, but driver safety deteriorates due to distraction
Solution Approach 1:
The system divides navigation change operations into two separate segments: (1) drivers can make basic navigation changes through simplified interfaces, and (2) passengers can make navigation changes through their own user devices. This segmentation allows the navigation system to remain adaptable while reducing the distraction burden on drivers by enabling passengers to handle complex navigation tasks.
2Object-affected harmful factors
If navigation system functionality is partially disabled while the vehicle is in operation, then driver safety is improved, but navigation adaptability deteriorates
Solution Approach 1:
The system implements multi-functionality by allowing multiple user devices (driver's device and passenger's device) to interact with the navigation system. The driver retains safety by not needing to manually operate complex navigation features, while the passenger's device provides an additional channel for making navigation changes, thus maintaining navigation adaptability without compromising driver safety.
Solution Approach 2:
The passenger's user device acts as an intermediary between the driver's navigation needs and the navigation system. The passenger can make navigation changes on their device, which then communicate with the vehicle's navigation system, indirectly fulfilling navigation adaptability requirements while keeping the driver focused on driving.
3Adaptability or versatility
If multiple user devices communicate with the navigation system, then navigation adaptability is improved, but device complexity increases
Solution Approach 1:
The system merges multiple navigation change inputs from different user devices into a unified navigation session. Instead of creating separate complex processing paths for each device, the system combines all navigation changes into a single session that is processed by the navigation system, reducing overall system complexity while supporting multiple devices.
Solution Approach 2:
The system creates a virtual copy of the navigation interface on the passenger's user device, allowing the passenger to interact with a replicated version of the navigation system. This copying approach allows multiple devices to access navigation functionality without requiring the physical navigation hardware to be replicated, thus managing complexity effectively.

AI summary
In accordance with some embodiments, multiple navigation changes to a navigation system may be managed. The navigation system may receive and first set of navigation changes. Then, the navigation system may establish communication with a user device. The navigation system may then receive a second set of navigation changes associated with the user device. As a result, the navigation system may merge the first set of navigation changes with the second set of navigation changes.
