Solution Overview

Problem

Existing receptacle socket assemblies for lighting equipment are not easily connectable to components, requiring complex and error-prone processes for both the receptacle and wire connections.

Innovation Solution

A receptacle socket assembly comprising a receptacle with multiple contact types for different signal types and a wire connector with corresponding contacts, designed for easy plugging and secure connection, featuring snap-fit mechanisms and ducts/channels for precise alignment and secure locking.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a traditional receptacle socket assembly is used for lighting equipment, then the connection process becomes complex and error-prone, but the connection security and reliability are maintained

Engineering Contradiction:
Improveease of connectionVSAvoidconnection process complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The invention divides the connection system into two separate modules: a receptacle socket assembly fixed to the housing and a wire connector assembly that receives wires and plugs into the receptacle. This segmentation allows each module to be independently prepared and connected, simplifying the overall connection process and reducing errors while maintaining connection security through the standardized plug-receptacle interface.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If the receptacle and wire connections are integrated into a single assembly, then the connection process is simplified, but the installation flexibility and error correction capability are reduced

Engineering Contradiction:
Improveconnection simplicityVSAvoidinstallation flexibility
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The invention enables preliminary preparation of both the receptacle socket assembly (fixed to housing) and the wire connector assembly (wires terminated and organized) before final connection. This preliminary action allows installers to prepare components separately, verify connections, and make corrections if needed before plugging the wire connector into the receptacle, combining simplicity with flexibility.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If multiple contact types are provided in the receptacle for different signal types, then the functionality and adaptability are improved, but the device complexity increases

Engineering Contradiction:
Improvesignal type compatibilityVSAvoidreceptacle structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The receptacle socket assembly incorporates multiple contact types (power contacts, data contacts, control contacts) within a single standardized interface design. This universal receptacle can accommodate different signal types through a unified plug-receptacle mechanism, providing multi-functionality without requiring separate connection systems for each signal type, thus balancing adaptability with manageable complexity.

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