Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a collaboration cell is determined based on initial transmission delay and bandwidth requirements, then the collaboration function can be established, but if transmission conditions change the collaboration function gain is reduced or the function fails

Engineering Contradiction:
Improvecollaboration function reliabilityVSAvoidadaptability to transmission condition changes
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamic re-evaluation of transmission scenarios by periodically acquiring updated transmission delays and bandwidths of collaboration cells. The network device dynamically adjusts the selection of collaboration cells based on current transmission conditions, transforming the static cell determination into a dynamic adaptation process that responds to changing network states.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent establishes a feedback mechanism where the network device continuously monitors transmission delays and bandwidths of collaboration cells, compares them against the preset collaboration function requirements, and triggers re-selection when deviations are detected. This closed-loop feedback ensures the collaboration function maintains optimal performance despite transmission condition variations.

Inventive Principle:
Principle #23Feedback

2Productivity

If transmission delay or bandwidth of a collaboration cell changes after determination, then the cell can continue to be used for collaboration, but the collaboration function gain is reduced

Engineering Contradiction:
Improvecollaboration function gainVSAvoidcell selection and monitoring complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent performs preliminary acquisition of transmission delays and bandwidths for candidate collaboration cells before final selection. By pre-evaluating transmission scenarios and identifying cells that meet requirements in advance, the system avoids complex real-time adjustments when conditions change, simplifying the overall selection process while maintaining high collaboration function gain.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent monitors changes in transmission parameters (delay and bandwidth) of collaboration cells and triggers re-selection when parameter deviations exceed thresholds. This parameter-based adaptation mechanism balances productivity maintenance with complexity control by only initiating re-selection when necessary, rather than continuously adjusting the collaboration configuration.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If a fixed collaboration cell is selected, then the system configuration is simple, but the system cannot adapt to changing transmission conditions

Engineering Contradiction:
Improveadaptability to transmission condition changesVSAvoidtransmission scenario acquisition and cell re-selection complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the collaboration cell selection process into distinct phases: initial transmission scenario acquisition, transmission condition monitoring, requirement comparison, and conditional re-selection. This segmentation allows the system to maintain simple configuration during stable periods while enabling complex adaptation only when transmission conditions change, balancing adaptability with complexity management.

Inventive Principle:
Principle #1Segmentation
