Problem

Existing discharging connector systems struggle to output multiple types of AC power with different voltages without requiring significant design changes, limiting their versatility in powering various electrical devices with distinct voltage requirements.

Innovation Solution

A discharging assembly with a three-line structure comprising a first voltage line, a second voltage line, and a neutral line, allowing for the output of AC power with different voltages through a single discharging connector, which includes multiple electrical outlets that can supply AC power with specific voltage configurations, enabling the connection of devices with varying voltage needs without substantial design modifications.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If two or more discharging ports are provided to output different voltages, then multiple types of AC power with different voltages can be output, but design change becomes significant

Engineering Contradiction:

Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The single discharging port is designed to serve multiple functions by incorporating a three-line structure (first voltage line, second voltage line, and neutral line) that can provide different voltage levels (first voltage and second voltage) through different terminal combinations, eliminating the need for multiple separate discharging ports

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

2Device complexity

If a single discharging port is used, then design change is suppressed, but it is difficult to drive multiple types of electrical devices with different driving voltages

Engineering Contradiction:
Improvedesign changeVSAvoidability to drive multiple types of electrical devices with different driving voltages
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The voltage output is segmented into multiple levels by utilizing different terminal combinations within the single discharging port - the first voltage line and second voltage line can be combined with the neutral line to provide different voltage levels, allowing multiple electrical devices with different voltage requirements to be driven simultaneously

Inventive Principle:
Principle #1Segmentation

AI summary

A discharging assembly includes: a first end to which electric power is input from a connected discharging port; a first voltage line, a second voltage line and a neutral line; and a second end that outputs first AC power and second AC power. The first AC power applies a first voltage between the first voltage line and the neutral line. The second AC power applies a second voltage between the second voltage line and the neutral line. The second end includes a first electrical outlet and a second electrical outlet. The first electrical outlet includes a first voltage terminal connected to the first voltage line, a second voltage terminal connected to the second voltage line, and a ground terminal connected to the neutral line. The second electrical outlet includes a voltage terminal connected to the first voltage line, and a ground terminal connected to the neutral line.
