Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a simple electrical connector is used to transmit power, then the device complexity is low, but interference, hum, and noise are generated in the connector

Engineering Contradiction:

Core Design Contradiction:
Device complexityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a power isolation chip as an intermediary component between the power source and the electrical device. This chip includes isolated input and output circuits that prevent direct electrical connection, thereby blocking ground loops and reducing interference, hum, and noise while maintaining power transmission functionality.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The connector apparatus is segmented into distinct functional components: an input connector for receiving power, a power isolation chip with separate input and output circuits, and an output connector for delivering power to the device. This segmentation allows each component to perform its specific function while isolating potential sources of interference.

Inventive Principle:
Principle #1Segmentation

2Productivity

If power is transmitted directly from source to device, then the power transmission is efficient, but the correct voltage and polarity cannot be ensured for different devices

Engineering Contradiction:
