Engineering Contradiction Analysis
1Adaptability or versatility
If wireless communication technology is adopted for FEMS networking, then networking establishment cost and process flexibility are reduced, but communication reliability and stability may be affected due to industrial environment factors
Solution Approach 1:
The patent applies parameter changes by evaluating multiple communication schemes across different parameters (data rate, latency, power consumption, cost) and selecting the optimal scheme based on normalized metric matrices. This allows the system to adapt communication parameters to match specific FEMS networking requirements while maintaining reliability through systematic comparison.
Solution Approach 2:
The patent creates a universal evaluation framework that can assess different communication schemes (wired, wireless, various wireless standards) using a common set of metrics and normalization methods. This multi-functional approach enables objective comparison across diverse communication technologies to determine suitability for FEMS applications.
2Measurement precision
If communication schemes are selected based on multiple parameters (OPEX, CAPEX, flexibility, data rate, reliability, latency, power, cost), then comprehensive suitability determination is achieved, but system complexity increases
Solution Approach 1:
The patent segments the complex evaluation process into distinct components: defining communication parameters, creating characteristic matrices, normalizing metrics, and calculating suitability scores. This segmentation breaks down the complex multi-parameter evaluation into manageable steps, improving measurement precision while organizing system complexity into structured modules.
Solution Approach 2:
The patent transforms multiple communication parameters into normalized metric matrices with consistent scales, enabling precise comparison across different parameters (OPEX, CAPEX, flexibility, data rate, reliability, latency, power, cost). This parameter transformation approach achieves comprehensive suitability determination through systematic normalization and metric calculation.
3Reliability
If wired communication is used for monitoring and controlling resources, then communication reliability is maintained in industrial environments, but networking establishment cost and process flexibility are reduced
Solution Approach 1:
The patent applies dynamics by enabling the FEMS to dynamically select communication schemes based on varying requirements across different energy management levels. The system can adapt between wired and wireless communications, and between different wireless standards, depending on the specific needs of each FEMS level, thus achieving both reliability and flexibility.
Solution Approach 2:
The patent creates a universal evaluation framework that assesses multiple communication schemes (wired, wireless, various wireless standards) using common metrics, enabling the system to select the most appropriate communication method for each FEMS level. This multi-functional approach maintains reliability while enabling process flexibility through objective comparison of different communication technologies.
