Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing XR technologies face issues with poor maintainability and user experience due to reliance on a single server for managing virtual characters across multiple terminals, leading to crashes that disrupt communication and collaboration.
Innovation Solution
A method and system for multi-terminal communication where any terminal device can broadcast its own communication address, allowing other devices to connect and share virtual reality models, enabling peer-to-peer communication and synchronization, and updating models independently or through a failed device, thus avoiding reliance on a single server.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single server is used to manage virtual characters across multiple terminals, then centralized control and coordination are achieved, but system reliability deteriorates because the entire system fails when the server crashes
Solution Approach 1:
The patent segments the centralized server architecture into distributed terminal devices, where each terminal can independently function as a server. This segmentation eliminates the single point of failure and improves system reliability while maintaining the necessary coordination capabilities through peer-to-peer communication.
Solution Approach 2:
The patent inverts the traditional client-server model by enabling terminal devices to serve dual roles as both clients and servers. Instead of terminals relying on a central server, any terminal can become the server, fundamentally reversing the dependency relationship and eliminating the reliability bottleneck.
2Ease of repair
If a single server manages all virtual reality models, then model consistency is maintained, but maintainability worsens because any terminal crash disrupts communication for all other terminals
Solution Approach 1:
The patent implements dynamic server selection where the server role can transition between different terminal devices based on operational status. This dynamic architecture ensures that if one terminal fails, another can immediately take over the server function, maintaining communication stability while improving maintainability.
Solution Approach 2:
The patent introduces a peer-to-peer communication mechanism as an intermediary layer between terminals, allowing direct communication that bypasses the need for a always-available central server. This intermediary communication channel ensures maintainability is not compromised by server failures.
3Adaptability or versatility
If all terminals communicate through a central server, then coordination is simplified, but adaptability deteriorates because the system cannot function without the server
Solution Approach 1:
The patent makes terminal devices universal by enabling them to perform multiple functions: acting as clients, servers, or both simultaneously. This multi-functionality greatly enhances system adaptability, allowing the network to reconfigure dynamically based on which terminals are available, while the standardized communication protocols keep complexity manageable.

AI summary
Provided is a method for multi-terminal communication based on a virtual reality model, and the method relates to the field of expanded reality technologies. According to the method, a terminal device searches for a first communication address in a local area network, broadcasts a second communication address through the local area network when the first communication address is not searched out, receives a plurality of requests from a plurality of terminal devices, and sends a plurality of virtual reality models to the plurality of terminal devices based on the plurality of requests. The plurality of terminal devices have one-to-one correspondence with the plurality of virtual reality models. The technical solution according to the present disclosure can avoid the problem of poor maintainability caused by all terminal devices in the local area being bound to a single server, thereby improving the usage experience.
