Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If only short-circuit detection is provided, then the device complexity is reduced, but the measurement precision and fault detection capability are insufficient

Engineering Contradiction:
Improvefault detection capabilityVSAvoiddetection system complexity
Core Design Contradiction:

Solution Approach 1:

The detection system is segmented into multiple independent detection modules: short-circuit detection module, open-circuit detection module, and overload detection module. Each module independently detects specific fault types, enabling comprehensive fault detection while keeping individual modules simple and manageable.

Inventive Principle:

Solution Approach 2:

The detection circuit is designed with multi-functionality to perform multiple detection tasks (short-circuit, open-circuit, overload detection) using a unified detection architecture. This allows the system to achieve comprehensive fault detection capability without proportionally increasing device complexity.

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

Solution Approach 1:

The detection circuit continuously monitors electrical parameters and pre-judges potential faults before they develop into serious problems. By performing preliminary detection and early warning, the system reduces the time required for actual fault determination and troubleshooting.
