Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If separate systems are used for communication, data processing, and voltage/current measurement, then adaptability to different terminal configurations is improved, but device complexity and installation cost increase

Engineering Contradiction:

Improveadaptability to terminal configurationsVSAvoidsystem complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The measurement system is divided into two independent modules: a main module containing power supply, current measurement, data processing, and communication means, and an auxiliary module containing voltage tapping means and electrical connection means. This segmentation allows each module to be optimized independently while maintaining overall system adaptability to different terminal configurations.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The main module is designed with universal functionality to work with different auxiliary modules through standardized electrical connection means. The main module can adapt to various terminal configurations by pairing with appropriately configured auxiliary modules, making the overall system universal without requiring each component to be complex.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Ease of operation

If a fully integrated module is used, then installation simplicity and compactness are improved, but adaptability to different terminal configurations deteriorates

Engineering Contradiction:

Improveinstallation simplicityVSAvoidadaptability to terminal configurations

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

Rather than using a single integrated module, the system segments functionality into a main module and auxiliary module that can be easily assembled together. This segmentation maintains installation simplicity through modular assembly while enabling adaptability by allowing different auxiliary modules to be paired with the main module for different terminal configurations.

Inventive Principle:

Principle #1Segmentation

3Productivity

If a compact integrated product is used, then measurement efficiency is improved, but adaptability to different terminal configurations without modifications deteriorates

Engineering Contradiction:

Improvemeasurement efficiencyVSAvoidadaptability without modifications

Core Design Contradiction:

ProductivityVSAdaptability or versatility

Solution Approach 1:

The main module is designed with universal electrical connection means that can interface with different auxiliary modules without requiring modifications to the main module itself. This universality allows the compact main module to maintain high measurement efficiency while adapting to various terminal configurations through the auxiliary module.

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Adaptability or versatility

If separate systems are used for each measurement function, then adaptability is improved, but installation cost and bulk increase

Engineering Contradiction:

Improveadaptability to configurationsVSAvoidinstallation bulk

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The system merges the power supply, current measurement, data processing, and communication means into a single main module, while combining voltage tapping and electrical connection functions in an auxiliary module. This merging reduces the overall quantity of components and installation bulk compared to completely separate systems, while maintaining adaptability through the modular interface between modules.

Inventive Principle:

Principle #5Merging (Combining)
