Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If measurement is conducted using existing measurement tools and methods, then measurement capability is maintained, but measurement precision and comprehensiveness are insufficient for new wireless communication technologies

Engineering Contradiction:
Improvemeasurement precisionVSAvoidadaptability to new wireless technologies
Core Design Contradiction:
Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The measurement device is designed with multi-functionality to support various wireless communication technologies (5G, Wi-Fi, Bluetooth, etc.) through a unified architecture that can adapt to different measurement scenarios. The device incorporates multiple communication protocol layer measurement capabilities in a single platform, enabling it to perform comprehensive measurements across different wireless standards without requiring separate specialized tools for each technology.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The device dynamically adjusts measurement parameters and protocols based on the target wireless communication technology being measured. The control unit modifies measurement configuration information, selected communication protocols, and measurement objects according to the specific technology requirements, allowing the same hardware to achieve precise measurements across diverse wireless standards by changing operational parameters rather than physical structure.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If measurement results are processed at multiple communication protocol layers, then measurement comprehensiveness is improved, but device complexity increases

Engineering Contradiction:
Improvemeasurement comprehensivenessVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The measurement device segments the measurement function across multiple communication protocol layers (physical layer, data link layer, network layer, etc.), with each layer having dedicated measurement modules that operate independently but coordinate through the control unit. This segmentation allows comprehensive multi-layer measurement while maintaining modular architecture that reduces overall system complexity through standardized interfaces and independent functional blocks.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The control unit serves as an intermediary that coordinates and manages the measurement processes across different communication protocol layers. It receives measurement configuration information, selects appropriate protocols, coordinates data collection from various layers, and processes results centrally. This intermediary structure simplifies the interaction between multiple measurement modules and reduces complexity by centralizing control logic.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Device complexity

If existing measurement tools are used for new wireless technologies, then device simplicity is maintained, but measurement accuracy for new technologies deteriorates

Engineering Contradiction:

Solution Approach 1:

The measurement device incorporates dynamic adaptability to automatically adjust its measurement parameters, selected protocols, and processing methods based on the detected wireless communication technology. Rather than using fixed measurement configurations, the device dynamically configures itself to match the target technology requirements, maintaining simplicity in operation while achieving high accuracy for emerging wireless standards through automated adaptation.

Inventive Principle:
Principle #15Dynamics
