Solution Overview

Problem

Existing electrical fixtures lack a safe and tool-less connection mechanism that securely attaches to electrical power sources while protecting exposed wires from accidental contact.

Innovation Solution

A plug and socket combination with a wire cover that includes a spindle and retaining balls for secure mechanical attachment, along with a removable cover to conceal electrical terminals and wires, ensuring safe and tool-less installation and disconnection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a plug and socket combination is used for quick connection, then ease of operation is improved, but wire exposure safety deteriorates

Engineering Contradiction:

Improvequick connectionVSAvoidwire exposure

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The wire cover is nested within the plug body, forming a layered protective structure. The wire cover is received by a recess in the plug body, creating a nested configuration where the wire cover is protected within the plug assembly while still providing external protection for exposed wires.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The wire cover acts as a flexible protective shell that covers and protects exposed electrical wires. This thin film or shell structure provides safety by concealing hazardous wire elements while maintaining the quick connect functionality of the plug and socket system.

Inventive Principle:

Principle #30Flexible shells and thin films

2Ease of operation

If electrical terminals are exposed for connection, then ease of operation is improved, but safety deteriorates due to accidental contact

Engineering Contradiction:

Improveterminal accessibilityVSAvoidaccidental contact

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The wire cover is nested within the plug body structure, creating a protective enclosure. The recess in the plug body receives the wire cover, forming a nested arrangement that protects terminals while allowing controlled access for connection operations.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The wire cover serves as a protective shell that conceals electrical terminals and wires. This shell structure provides safety by preventing accidental contact with exposed electrical components while maintaining the ability to perform connections when needed.

Inventive Principle:

Principle #30Flexible shells and thin films

AI summary

A quick-connect plug and socket for mechanically and electrically attaching an electrical fixture. The plug has a spindle insertable into a bore of the socket to mechanically engage the plug and socket. An electrical connection forms between ring-shaped conductors on the plug that insert into ring-shaped openings in the socket to engage contacts within the socket. The plug body includes an extension extending from a side of the body to the spindle. The extension has a channel and slot, through which an electrical cord with wires inserts without threading the cord through the extension. The cord turns away from the extension to lie in a channel in the body and extend to a periphery of the body, to then connect to electrical terminals of the body. A removable cover covers the cord in the channel, the terminals, and the portion of wire that passes from the periphery to the terminals.
