Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If terminal profiles are determined using existing methods, then some level of network management is achieved, but the accuracy and adaptability to terminal categories is insufficient

Engineering Contradiction:
Improveterminal profile determination accuracyVSAvoidadaptation to terminal category
Core Design Contradiction:
Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The patent segments terminals into different categories based on their profiles, and applies different detection strategies and parameters for each category. The network device determines terminal categories first, then selects appropriate detection methods and parameters tailored to each category, enabling both high accuracy and adaptability simultaneously.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent dynamically adjusts detection parameters such as detection probability, detection interval, and detection frequency based on terminal category and network conditions. By changing these parameters adaptively, the system achieves high measurement precision while maintaining versatility across different terminal types and network scenarios.

Inventive Principle:
Principle #35Parameter changes

2Measurement precision

If terminals are detected multiple times to improve profile accuracy, then determination precision is improved, but network overhead increases

Engineering Contradiction:
Improveprofile determination accuracyVSAvoidnetwork overhead
Core Design Contradiction:
Measurement precisionVSLoss of energy

Solution Approach 1:

The patent dynamically adjusts detection parameters including detection probability, detection interval, and detection frequency based on terminal category, network load, and current conditions. This enables multiple detections when needed for high accuracy while reducing detection frequency to minimize overhead, achieving both precision and energy efficiency.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent applies partial detection strategies where not all terminals are detected with the same frequency. Instead, detections are performed selectively based on terminal category and network conditions, performing enough detections to achieve required accuracy while avoiding excessive actions that would increase overhead unnecessarily.

Inventive Principle:
Principle #16Partial or excessive action

3Measurement precision

If detailed terminal detection is performed to accurately determine profiles, then measurement precision improves, but device complexity increases

Engineering Contradiction:
Improveterminal profile accuracyVSAvoiddetection system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent divides the detection process into stages: first determining terminal category, then selecting appropriate detection parameters and methods for that category. This segmentation allows detailed detection when needed while using simplified methods for other cases, maintaining precision without unnecessary complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies different detection qualities and levels of detail to different terminal categories and network conditions. Rather than using uniformly high-detail detection for all terminals, the system applies locally optimized detection strategies tailored to each terminal's category and current network state, achieving accuracy while managing complexity.

Inventive Principle:
Principle #3Local quality
