Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple access points operate within a geographic area to provide coverage, then network coverage is improved, but interference between access points increases
Solution Approach 1:
The patent merges the control of multiple access points into a unified system that models their interactions as a single optimization problem. By combining individual access point control into a joint optimization framework, the system can coordinate their operations to achieve overall performance improvement while managing interference between them.
Solution Approach 2:
The system changes operational parameters of access points (such as transmit power, channel selection, and timing) based on a modeled state-space representation. By dynamically adjusting these parameters according to the modeled interactions and performance predictions, the system optimizes the balance between coverage and interference management.
2Productivity
If access points operate independently without joint control, then device complexity is reduced, but overall network performance is suboptimal
Solution Approach 1:
The patent segments the complex network optimization problem into manageable components by modeling the system as a state-space with discrete states and transitions. This segmentation allows the complex interactions between multiple access points to be represented and optimized through a structured framework that breaks down the overall optimization into smaller, more manageable sub-problems.
Solution Approach 2:
The system introduces a centralized controller or coordinator that acts as an intermediary between access points. This intermediary manages the joint optimization by collecting information from individual access points, modeling their interactions, and coordinating their operations to achieve overall performance improvement without requiring each access point to independently manage complex interactions.
3Reliability
If operational characteristics of one access point are changed to improve its performance, then individual performance is improved, but performance of other access points may be negatively affected
Solution Approach 1:
The system implements feedback mechanisms where the performance changes of individual access points are monitored and fed back into the state-space model. This feedback allows the model to capture the actual impact of operational changes on the overall network, enabling subsequent optimization decisions to account for these effects and adjust parameters to balance individual and collective performance.
