Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If automatic control of communication parameters is used, then the wireless communication system can adapt to changing conditions, but measurement precision deteriorates due to parameter variations during testing

Engineering Contradiction:

Improveautomatic adaptation of communication parametersVSAvoidprecision of radiation behavior measurements

Core Design Contradiction:

Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The system provides dynamic control over the automatic parameter control mechanism. The beam pattern and communication parameters can be locked in specific states during measurement to ensure precision, while remaining dynamically adjustable during normal operation to maintain adaptability. This resolves the contradiction by making the system's behavior configurable based on operational context.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The invention introduces a locking mechanism that changes the state of communication parameters from dynamically varying to fixed. By allowing parameters to be locked at specific values during measurement, the system achieves precise measurements while maintaining the capability to change parameters when needed for adaptability during normal operation.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If beam pattern is locked to ensure measurement precision, then measurement reliability improves, but device complexity increases due to additional locking control mechanisms

Engineering Contradiction:

Improvereliability of measurementsVSAvoidcomplexity of beam pattern control

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The locking mechanism is integrated into the existing beam pattern control system, allowing the apparatus to lock and unlock beam patterns autonomously based on operational requirements. The controller automatically manages the locking state without requiring external intervention, which reduces operational complexity while maintaining measurement reliability.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The locking mechanism serves multiple functions: it ensures measurement precision during testing, maintains consistent beam patterns during calibration, and can be used to reproduce specific radiation characteristics for various measurement scenarios. This multi-functionality reduces the need for separate control mechanisms, thereby limiting the increase in device complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Measurement precision

If communication parameters are locked during measurement, then measurement precision improves, but adaptability to changing operational conditions deteriorates

Engineering Contradiction:

Improveprecision of communication parameter measurementsVSAvoidadaptability to changing operational conditions

Core Design Contradiction:

Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The system allows dynamic switching between locked and unlocked states of communication parameters. During measurement, parameters are locked to ensure precision. During normal operation or when adaptability is needed, the locking is released and parameters can automatically adjust to changing conditions. This dynamic state change resolves the contradiction between precision and adaptability.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system can lock parameters in advance before measurement to ensure consistent starting conditions, and then unlock them when needed for adaptability. This preliminary locking action ensures measurement precision without permanently sacrificing adaptability, as the system can transition between states as operational requirements change.

Inventive Principle:

Principle #10Preliminary action
