Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If relay power is allocated uniformly to all microgrids, then device complexity is reduced, but transmission reliability and data loss rate worsen for services with different importance levels
Solution Approach 1:
The patent applies local quality by allocating relay power differently to different microgrids based on their service importance. The control center calculates and assigns specific power levels to each relay according to the importance of services they transmit, ensuring that critical services receive sufficient power for reliable transmission while less critical services receive proportionally less power, thus resolving the contradiction between uniform allocation simplicity and transmission reliability.
2Reliability
If more relay power is allocated to ensure low data loss rate, then transmission reliability improves, but energy consumption increases
Solution Approach 1:
The patent changes the power allocation parameter from a uniform value to a differentiated value based on service importance. The control center calculates the importance of each service and adjusts the relay power allocation accordingly, ensuring that critical services receive enough power to maintain low data loss rates while non-critical services receive reduced power, thus optimizing the balance between transmission reliability and energy consumption.
3Reliability
If relay power is optimized for critical services, then transmission reliability of critical services improves, but the number of services that can be supported decreases
Solution Approach 1:
The patent applies local quality by differentiating power allocation across multiple services based on their importance levels. Instead of providing equal power to all services or concentrating all power on critical services, the system allocates power locally to each service according to its importance, enabling the system to support multiple services simultaneously while ensuring critical services receive sufficient power for reliable transmission.
