Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote support systems for vehicles lack flexibility in communication configuration and scalability, particularly in managing resources and relay devices, leading to potential communication delays and system instability.
Innovation Solution
A remote support system comprising a management device and relay devices that dynamically select and manage support resources and relay data communication, allowing for adaptable scaling and redundancy to maintain system functionality even when some devices fail.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single integrated device performs both management and relay functions, then device complexity is reduced, but adaptability to scale changes deteriorates
Solution Approach 1:
The system divides the remote support functionality into two separate functional units: a management device that handles support requests and resource allocation, and relay devices that handle data communication relaying. This segmentation allows independent scaling of each component, improving adaptability while maintaining manageable complexity through clear functional separation.
Solution Approach 2:
The management device is designed to universally manage multiple relay devices and support resources, coordinating their functions centrally. This multi-functionality allows the system to adapt to different scales by dynamically allocating resources through the management device without requiring structural changes to individual components.
2Stability of the object's composition
If relay devices are fixed in number and configuration, then system stability is improved, but adaptability to scale changes deteriorates
Solution Approach 1:
The system employs dynamic relay device selection where the management device can choose from multiple candidate relay devices based on current system conditions, load requirements, and communication quality. This dynamic allocation maintains stability through consistent performance while enabling scale adaptation by adjusting the number and configuration of active relay devices as needed.
3Reliability
If relay devices are selected from multiple candidates, then function sustainability is improved, but device complexity deteriorates
Solution Approach 1:
The management device serves as an intermediary that handles the complexity of selecting and managing multiple relay device candidates. It implements selection criteria and coordination logic centrally, ensuring function sustainability through redundancy while shielding individual relay devices from complex management tasks, thus distributing complexity appropriately.
4Stability of the object's composition
If communication configuration is fixed, then system stability is improved, but adaptability deteriorates
Solution Approach 1:
The system pre-establishes multiple relay device candidates with defined communication capabilities and selection criteria. This preliminary preparation enables rapid adaptation to scale changes by activating appropriate relay devices from the pre-configured pool, while maintaining communication stability through established protocols and predefined communication paths.

AI summary
A remote support system for remote support of a moving body includes a management device and one or more relay devices different from the management device. The management device is configured to receive a support request transmitted from the moving body and select a support resource required for the remote support. The one or more relay devices are configured to relay data communication performed during the remote support between the moving body and a remote support terminal.
