Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If the auxiliary receiver is used to receive signals, then power consumption is reduced, but coverage is poor and signal reception reliability deteriorates

Engineering Contradiction:

Improvepower consumptionVSAvoidsignal reception reliability

Core Design Contradiction:

Use of energy by moving objectVSReliability

Solution Approach 1:

The patent introduces a receiver selection mechanism that acts as an intermediary between the auxiliary receiver and main receiver. Based on coverage measurements, the system dynamically selects which receiver should be used, ensuring that the auxiliary receiver is only used when coverage conditions are sufficient, thus maintaining reliability while achieving power savings.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system dynamically adjusts receiver selection based on real-time coverage measurements. The terminal device measures coverage of first-type signals and dynamically determines whether to use the auxiliary receiver or switch to the main receiver, making the system adaptable to changing signal conditions rather than being static.

Inventive Principle:

Principle #15Dynamics

2Device complexity

If the auxiliary receiver is used to receive signals, then demodulation complexity is reduced, but coverage is poor and communication reliability deteriorates

Engineering Contradiction:

Improvedemodulation complexityVSAvoidcommunication reliability

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The receiver selection mechanism serves as an intermediary that prevents the auxiliary receiver from being used in poor coverage conditions. By measuring coverage first and selecting the appropriate receiver based on measurements, the system ensures that low-complexity reception is only used when it won't compromise communication reliability.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Reliability

If the main receiver is always used to receive signals, then signal reception reliability is maintained, but power consumption increases

Engineering Contradiction:

Improvesignal reception reliabilityVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system dynamically switches between receiver modes based on coverage measurements. When coverage is sufficient, the low-power auxiliary receiver is used; when coverage is poor, the high-reliability main receiver is activated. This dynamic adaptation maintains reliability while minimizing power consumption compared to always using the main receiver.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes the operational parameter of which receiver is active based on measured coverage conditions. By adjusting this parameter dynamically, the system optimizes the trade-off between power consumption and reception reliability, using the auxiliary receiver when possible and the main receiver only when necessary.
