Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple links are used for wireless communication, then throughput and reliability are improved, but device complexity and management difficulty increase
Solution Approach 1:
The patent segments the wireless communication system into multiple independent links, each with its own station (STA) operating on different frequency bands (2.4 GHz, 5 GHz, 6 GHz). Each link can be managed and configured separately through per-STA profile subelements, allowing the system to achieve high throughput through parallel communication while maintaining manageable complexity by dividing the overall system into separatable components.
Solution Approach 2:
The multi-link device (MLD) implements a universal management framework that can handle multiple types of links (2.4 GHz, 5 GHz, 6 GHz bands) through a common architecture. The inheritance rule mechanism provides a universal method for configuring and managing diverse link types, enabling the system to adapt to different frequency bands and communication requirements without requiring separate management systems for each link type.
2Adaptability or versatility
If link reconfiguration is implemented for adding/removing stations, then adaptability is improved, but communication overhead and processing time increase
Solution Approach 1:
The patent implements preliminary action by establishing inheritance rules in advance that automatically determine how configuration parameters are propagated when stations are added or removed from links. The per-STA profile subelements are pre-configured with inheritance relationships, so that when reconfiguration is needed, the system can quickly apply pre-defined rules rather than calculating configurations from scratch, reducing processing time while maintaining adaptability.
Solution Approach 2:
The link reconfiguration mechanism uses feedback through the inheritance rule system, where configuration changes in one link automatically propagate to other linked stations through predefined inheritance relationships. This feedback mechanism allows the system to adapt to changing conditions (adding/removing stations) while minimizing manual intervention and processing time, as the inheritance rules automatically handle the propagation of configuration changes across the multi-link system.
