Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If default power control parameters are used for both serving and non-serving cells, then device complexity is reduced and ease of operation is improved, but transmission power control performance deteriorates and interference increases

Engineering Contradiction:

Improveease of operationVSAvoidtransmission power control performance

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent segments the power control parameters into two distinct sets: one for serving cells and another for non-serving cells. This segmentation allows each set to be optimized independently for its specific function, resolving the contradiction by maintaining simplicity through automated segmentation while improving reliability through specialized parameter optimization for each cell type.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent applies local quality by assigning different power control parameters tailored to specific cell types. Serving cells use parameters optimized for primary communication, while non-serving cells use parameters optimized for interference management and supplemental communication. This localized optimization improves overall system reliability without significantly increasing operational complexity.

Inventive Principle:

Principle #3Local quality

2Reliability

If different default power control parameters are used for serving and non-serving cells, then transmission power control is improved and interference is reduced, but device complexity increases

Engineering Contradiction:

Improvetransmission power control performanceVSAvoiddevice complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements self-service by enabling the wireless device to automatically select and apply the appropriate power control parameter set based on whether the cell is identified as serving or non-serving. This self-service mechanism resolves the contradiction by improving reliability through differentiated parameters while minimizing the increase in device complexity through automated parameter selection.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent introduces dynamics by making the power control parameter selection adaptive and dynamic rather than static. The device dynamically adjusts which parameter set to use based on real-time cell identification, allowing the system to optimize performance for each transmission while keeping the overall device architecture relatively simple through dynamic adaptation.

Inventive Principle:

Core Design Contradiction:

Ease of operationVSManufacturing precision

Solution Approach 1:

The patent segments power control into distinct parameter sets for serving and non-serving cells, which resolves the contradiction by maintaining ease of operation through automated segmentation while improving transmission precision. The segmentation allows each cell type to use parameters optimized for its specific role, reducing error rates without requiring manual configuration.

Inventive Principle:

Solution Approach 1:

The patent applies self-service by enabling the device to automatically manage the complexity of differentiated power control parameters. The device autonomously identifies cell types and selects appropriate parameter sets, which improves productivity through optimized data rates while minimizing the impact on device complexity through automated parameter management.
