Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If antenna transmission power is increased to maintain communication quality, then signal reliability is improved, but power consumption increases

Engineering Contradiction:
Improvesignal reliabilityVSAvoidpower consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system performs preliminary actions by creating a signal strength map in advance that predicts future signal conditions. This allows the device to proactively adjust transmission power before signal degradation occurs, rather than reactively increasing power after quality drops. The map is built using historical signal strength data and reliability coefficients, enabling predictive power optimization that maintains signal reliability while minimizing unnecessary power consumption increases.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system dynamically adjusts antenna transmission power based on real-time signal conditions and predictive map data. Instead of using a fixed or manually set power level, the transmission power adapts continuously to changing environmental conditions, device location, and signal characteristics. This dynamic adjustment ensures signal reliability is maintained only when necessary, reducing overall power consumption.

Principle #15Dynamics

2Use of energy by moving object

If transmission power is adjusted reactively based on current signal conditions, then power consumption is reduced, but signal quality deteriorates before adjustment occurs

Engineering Contradiction:
Improvepower consumptionVSAvoidsignal quality
Core Design Contradiction:
Use of energy by moving objectVSReliability

Solution Approach 1:

The system creates a predictive signal strength map in advance that anticipates future signal conditions based on historical data and reliability coefficients. This preliminary action allows the device to adjust transmission power proactively before signal quality actually deteriorates, eliminating the delay inherent in reactive adjustment systems. The map predicts where signal strength will drop, allowing pre-emptive power increases to maintain quality.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system uses feedback from historical signal strength measurements and reliability coefficients to continuously refine the predictive map. By monitoring actual signal conditions and comparing them with predictions, the system learns from past performance and improves its future predictions. This feedback loop ensures that power adjustments are both proactive and accurate, maintaining signal quality while optimizing power consumption.

3Measurement precision

If signal strength map is created using historical data, then prediction accuracy is improved, but system complexity increases

Engineering Contradiction:

Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system segments the signal prediction problem by creating a spatial map divided into discrete locations or grid cells. Each segment of the map stores signal strength data and reliability coefficients for specific geographic areas. This segmentation allows the complex prediction task to be broken down into manageable, location-specific calculations, improving prediction accuracy while keeping the computational complexity distributed and manageable.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system creates a simplified copy or model of the physical environment in the form of a signal strength map. Instead of performing complex real-time physics calculations to predict signal behavior, the system uses a pre-built map that copies essential signal characteristics from historical measurements. This model-based approach provides accurate predictions without requiring complex computational resources during operation.

Inventive Principle:
Principle #26Copying
