Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If high wireless transmission power is used to ensure through-wall performance, then signal coverage is improved, but resource wastage increases and health risks arise

Engineering Contradiction:
Improvesignal coverageVSAvoidresource wastage
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The patent implements dynamic transmission power adjustment by monitoring signal strength feedback from access devices and automatically modifying transmission power levels. The system transitions from static high power mode to adaptive dynamic control, adjusting power in real-time based on actual coverage needs and device locations.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes the transmission power parameter based on measured signal strength and coverage requirements. By monitoring RSSI (Received Signal Strength Indicator) feedback from access devices and adjusting the transmission power parameter accordingly, the system optimizes between coverage reliability and energy efficiency.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If high wireless transmission power is used to ensure through-wall performance, then signal coverage is improved, but health risks to humans increase

Engineering Contradiction:
Improvesignal coverageVSAvoidhealth risks
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The system dynamically adjusts transmission power based on actual coverage needs rather than maintaining constantly high power. By implementing real-time monitoring and adaptive control, the system reduces unnecessary high-power transmission that contributes to health risks while maintaining adequate signal coverage.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The transmission power parameter is adjusted based on signal strength measurements and coverage requirements. The system transitions from fixed high power settings to variable power levels that match actual operational needs, thereby reducing harmful radiation exposure while maintaining network reliability.

Inventive Principle:
Principle #35Parameter changes

3Loss of energy

If transmission power is reduced to save resources, then energy efficiency is improved, but signal coverage deteriorates

Engineering Contradiction:
Improveenergy efficiencyVSAvoidsignal coverage
Core Design Contradiction:
Loss of energyVSReliability

Solution Approach 1:

The patent implements a feedback mechanism where access devices report signal strength (RSSI) to the base station. The base station uses this feedback information to determine whether current transmission power levels are sufficient or need adjustment, enabling data-driven power optimization that balances energy efficiency with coverage requirements.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system employs dynamic power adjustment rather than static low-power operation. Transmission power is continuously adapted based on feedback from access devices, allowing the system to use low power when sufficient and increase power only when coverage gaps are detected, optimizing the trade-off between energy efficiency and signal coverage.

Inventive Principle:
Principle #15Dynamics
