Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If continuous measurement by user equipment is performed, then measurement precision is improved, but energy consumption increases

Engineering Contradiction:
Improvemeasurement precisionVSAvoidenergy consumption
Core Design Contradiction:
Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The patent implements periodic measurement activation where user equipment alternates between measuring and non-measuring states. The network entity controls this by sending activation indications to specific user equipment at specific times, allowing measurements to be performed periodically rather than continuously, thus reducing energy consumption while maintaining measurement precision when needed.

Inventive Principle:
Principle #19Periodic action

2Measurement precision

If all user equipment performs measurements continuously, then measurement precision is improved, but network resource usage increases

Engineering Contradiction:
Improvemeasurement precisionVSAvoidnetwork resource usage
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

The patent extracts the measurement function from all user equipment and concentrates it on specifically selected measuring user equipment. The network entity identifies and designates particular user equipment as measuring entities based on their capabilities and current network conditions, allowing only these selected devices to perform measurements and report data, thereby reducing overall network resource usage while maintaining measurement precision.

Inventive Principle:
Principle #2Taking out (Extraction)

3Measurement precision

If data collection is increased, then measurement precision is improved, but data analysis complexity increases

Engineering Contradiction:
Improvemeasurement precisionVSAvoiddata analysis complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent extracts and filters measurement data at the source by having the network entity selectively request and collect data only from measuring user equipment that are specifically designated for certain measurement tasks. This selective data collection approach reduces the overall volume of data requiring analysis while maintaining measurement precision through targeted measurements from capable devices.

Inventive Principle:
Principle #2Taking out (Extraction)
