Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If hardware components from different manufacturers are used, then hardware diversity and adaptability are improved, but interoperability deteriorates and communication complexity increases
Solution Approach 1:
The patent introduces a digital identity container as an intermediary component that mediates communication between hardware components from different manufacturers. This container standardizes the interaction interface, allowing diverse hardware to interoperate through a unified digital identity framework without requiring manufacturer-specific integration protocols, thereby reducing communication complexity while maintaining hardware diversity.
Solution Approach 2:
The digital identity container serves as a universal component that can be applied across different hardware manufacturers and communication scenarios. It provides multi-functional capabilities including identity authentication, permission management, and standardized communication protocols, enabling a single solution to handle diverse hardware interoperability requirements without requiring multiple specialized integration methods.
2Speed
If complex communication systems are used, then transmission capability is improved, but security management complexity increases
Solution Approach 1:
The patent segments security management into discrete functions within the digital identity container, including separate modules for identity authentication, permission verification, and communication security. This segmentation allows complex security operations to be divided into manageable, standardized steps that can be executed independently, reducing overall security management complexity while maintaining robust security for high-speed communication.
Solution Approach 2:
The digital identity container implements self-service security mechanisms where the system automatically performs identity verification, permission checks, and security protocol selection without requiring manual security configuration or complex security management interventions. This automated approach simplifies security management while ensuring secure data transmission across the network.
3Adaptability or versatility
If multiple integration methods are used for different entities, then adaptability is improved, but connection process complexity increases
Solution Approach 1:
The patent standardizes connection parameters through the digital identity container, which defines uniform fields and formats for identity information, permission data, and communication protocols. By changing the parameter representation to a standardized format, the system achieves compatibility across different entities while simplifying the connection process to a single standardized procedure rather than multiple entity-specific integration methods.
Data Source
AI summary
This application provides a communication method, apparatus, and system, and a mobile carrier. The method may include: receiving a first request message from a first node, where the first request message includes a requested node type and a first digital identity of the first node; determining, based on the first digital identity, a first digital identity container associated with the first digital identity, where the first digital identity container stores attribute information of the first node; determining, based on the first digital identity container, at least one candidate node corresponding to the requested node type; and sending a first feedback message to the first node, where the first feedback message includes a digital identity list corresponding to the at least one candidate node, and the digital identity list includes a second digital identity corresponding to a second node to which the first node is to connect.
