Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traditional simple ratio method is used for capacity planning, then the planning process is simple and fast, but the accuracy of capacity estimation is insufficient

Engineering Contradiction:
Improveplanning process efficiencyVSAvoidcapacity estimation accuracy
Core Design Contradiction:
ProductivityVSMeasurement precision

Solution Approach 1:

The patent transforms the static, one-time ratio calculation into a dynamic iterative process. The system continuously adjusts the number of users and recalculates system capacity through multiple iterations, incorporating feedback from each iteration to improve the accuracy of capacity estimation while maintaining planning efficiency.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements a feedback mechanism where the results of each iteration are used to adjust parameters for the next iteration. The system evaluates whether the estimated capacity meets requirements and feeds this information back into the planning process, allowing continuous refinement of capacity estimates until convergence is achieved.

Inventive Principle:
Principle #23Feedback

2Ease of manufacture

If static simple estimation is used without network operation features, then the planning method is easy to implement, but it does not reflect actual network operation characteristics

Engineering Contradiction:
Improveimplementation simplicityVSAvoidnetwork operation reflection accuracy
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The patent changes the parameters used in capacity planning from static, generic values to dynamic parameters that reflect actual network operation features. The system incorporates service types, user behaviors, and network conditions as variable parameters that are updated throughout the iterative process, making the planning more reliable while remaining implementable.

Inventive Principle:
Principle #35Parameter changes

3Device complexity

If rough capacity superposition is used for multi-service estimation, then the calculation is simple, but it does not consider actual service characteristics

Engineering Contradiction:
Improvecalculation complexityVSAvoidmulti-service capacity estimation accuracy
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The patent segments the multi-service capacity estimation process into distinct components, analyzing each service type separately with its own characteristics and requirements. The system divides the overall capacity planning into service-specific sub-plans, then aggregates them through iteration, achieving accurate multi-service estimation without excessive calculation complexity.

Inventive Principle:
Principle #1Segmentation

4Ease of operation

If no iterative estimation is performed, then the planning process is straightforward, but it cannot adapt to different network scenes

Engineering Contradiction:
Improveplanning process straightforwardnessVSAvoidscene adaptability
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent introduces dynamics into the planning process through iterative estimation that adapts to different network scenes. The system automatically adjusts its behavior based on the specific scene being planned, modifying parameters and evaluation criteria according to the network conditions, service types, and requirements of each particular scenario.

Inventive Principle:
Principle #15Dynamics
