Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple distributers or couplers are connected in multiple stages to switch between antennas and measurement apparatus, then the number of antennas and frequency bands can be increased, but the signal loss is significantly increased

Engineering Contradiction:

Improvenumber of antennas and frequency bandsVSAvoidsignal loss

Core Design Contradiction:

Adaptability or versatilityVSLoss of energy

Solution Approach 1:

The system pre-calculates and stores optimal wiring diagrams in the memory unit before actual measurements are taken. When a measurement test is initiated, the appropriate pre-configured wiring diagram is automatically selected and applied, eliminating the need for real-time multi-stage switching and reducing signal loss through direct connection paths.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The control unit acts as an intermediary that manages the connection between the measurement apparatus and mobile terminal by selecting appropriate wiring diagrams from memory. This intermediary function coordinates the measurement device, cable, and antenna terminals to establish optimal connections without requiring multiple distributers or couplers in series.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If multiple distributers or couplers are connected in multiple stages to support multiple frequency bands, then the adaptability increases, but the cost increases

Engineering Contradiction:

Improvesupport for multiple frequency bandsVSAvoidcost

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The measurement apparatus is designed with a universal connection interface that can support multiple frequency bands through software-controlled wiring diagram selection rather than hardware multi-functionality. The single measurement device can be configured to measure different frequency bands by selecting appropriate pre-stored wiring diagrams, eliminating the need for multiple specialized devices or expensive multi-stage distributer systems.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

Instead of using expensive physical multi-stage distributer or coupler systems, the patent creates virtual copies of connection configurations through stored wiring diagrams in memory. These digital representations allow the system to simulate and switch between different connection topologies for various frequency bands without requiring corresponding physical hardware for each configuration.

Inventive Principle:

Principle #26Copying

3Adaptability or versatility

If the connection configuration between mobile terminal and measurement apparatus is changed to accommodate multiple antennas and frequency bands, then the adaptability increases, but the time and effort required for user configuration increases

Engineering Contradiction:

Improveconnection configuration flexibilityVSAvoidtime and effort for user configuration

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The measurement apparatus automatically selects and applies the appropriate wiring diagram based on the measurement test requirements without requiring user configuration. The system serves itself by automatically determining the optimal connection configuration between the measurement device, cable, and antenna terminals, eliminating the time and effort that would otherwise be required for manual user setup and reconfiguration.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system performs preliminary configuration by pre-calculating and storing optimal wiring diagrams in memory before actual measurements are taken. When a measurement test is initiated, the appropriate pre-configured wiring diagram is automatically selected and applied, eliminating the need for real-time user configuration and reducing setup time.

Inventive Principle:

Principle #10Preliminary action
