Solution Overview

Problem

Existing methods for connecting LED drive power supplies to three-phase power require complex line structures and lengthy mounting times, leading to inefficiencies and instability when adding new electrical devices.

Innovation Solution

A plug connector with a connecting assembly, phase shifting assembly, and terminal assembly that allows for flexible phase line selection by moving a phase shifting assembly to connect or disconnect from phase-line terminal members, simplifying the line structure and reducing mounting time.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a connector and phase shifter are mounted on the same line to achieve power phase shifting, then the phase shifting function is realized, but the line structure becomes complex and mounting time increases

Engineering Contradiction:
Improvepower phase shifting functionVSAvoidline structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines the connector and phase shifter into a single integrated plug connector assembly. The connector body houses the phase shifting mechanism internally, so that when the connector is mounted on the power line, the phase shifting function is automatically enabled without requiring separate components. This merging eliminates the need for complex line structures with multiple separate devices.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The plug connector is designed to perform multiple functions: electrical connection and power phase shifting. The connector body serves as both the mounting structure for electrical connection and the housing for the phase shifting mechanism. This multi-functionality allows a single device to replace what would traditionally require separate connector and phase shifter components.

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

2Adaptability or versatility

If a connector and phase shifter are mounted on the same line to achieve power phase shifting, then the phase shifting function is realized, but mounting time increases and efficiency decreases

Engineering Contradiction:
Improvepower phase shifting functionVSAvoidmounting efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

By integrating the phase shifting mechanism directly into the connector body, the patent reduces the number of separate mounting operations. The single integrated assembly can be installed in one operation rather than requiring separate mounting of a connector and phase shifter, thereby reducing mounting time and improving installation efficiency.

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If phase shifting assembly is moved to connect or disconnect from multiple phase-line terminal members, then flexibility and adaptability are enhanced, but device complexity increases

Engineering Contradiction:
Improvephase shifting capabilityVSAvoidconnector structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent incorporates a movable phase shifting assembly that can be positioned to connect to different phase-line terminal members. The movability is achieved through a guide slot mechanism that constrains the movement path, allowing the phase shifting assembly to selectively engage with different phases while maintaining a relatively simple overall structure. The dynamic positioning capability provides flexibility without requiring complex switching mechanisms.

Inventive Principle:
Principle #15Dynamics

AI summary

This application provides a plug connector for arbitrary phase shifting including a connecting assembly, a phase shifting assembly, and a terminal assembly. The connecting assembly is electrically connected to an electrical device; the terminal assembly includes a plurality of phase-line terminal members, and the phase-line terminal member is electrically connected to a phase line; and the phase shifting assembly is movably bridged between the connecting assembly and the plurality of phase-line terminal members. The phase shifting assembly is moved to enable two ends of the phase shifting assembly to be electrically connected to or disconnected from the connecting assembly and one of the phase-line terminal members, respectively. This application further provides a lamp. In this application, the phase shifting assembly is arranged and moved to enable one end thereof to be electrically connected to one of the phase-line terminal members, achieving that one of three phase lines is selected for connection. Any phase line can be selected based on the actual situation to provide electric energy, thus achieving power phase shifting. This is equivalent to integrating the power phase shifting function on a connector without the need to mount both the connector and a phase shifter on the same line. This simplifies the line structure, reduces the line connection difficulty, and improves the mounting efficiency.
