Solution Overview

Problem

Conventional lamp sockets are restricted by limited internal space, making it difficult to install light bulbs that occupy a large space, especially in narrow or special installation environments.

Innovation Solution

An extension lamp socket comprising a first and second half shell, electrode plates, and an electrode holding ring, with snapping and jointing structures, threaded convex bodies, and clamping slots, allowing for secure and conductive connections to accommodate large light bulbs in tight spaces.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a conventional lamp socket is used, then the structure is simple and easy to manufacture, but it cannot accommodate light bulbs that occupy a large space in narrow installation spaces

Engineering Contradiction:
Improveaccommodation of large light bulbsVSAvoidsocket structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The lamp socket is divided into multiple segments including a first half shell, a second half shell, an extension segment, and a clamping segment. Each segment serves a specific function: the half shells form the basic socket structure, the extension segment provides additional space for large bulbs, and the clamping segment secures the bulb. This segmentation allows the socket to accommodate various bulb sizes while maintaining a manageable structural complexity through modular assembly.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If the lamp socket is located at a narrow or special installation space, then the installation location is fixed, but it becomes difficult for hands to reach in for installing or removing light bulbs

Engineering Contradiction:
Improveease of bulb installationVSAvoidsocket extension length
Core Design Contradiction:
Ease of operationVSLength of stationary object

Solution Approach 1:

The lamp socket utilizes a multi-dimensional configuration with the extension segment extending outward from the main socket body in a direction perpendicular to the installation surface. This dimensional extension allows the bulb installation area to be accessible from outside narrow or special spaces, transforming a one-dimensional constraint into a multi-dimensional solution where bulbs can be installed without reaching into the confined space.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Volume of moving object

If the internal space of the lampshade is limited, then the overall size is compact, but it restricts the installation of special and novel style light bulbs that occupy large space

Engineering Contradiction:
Improvelight bulb space requirementVSAvoidlampshade internal space
Core Design Contradiction:
Volume of moving objectVSVolume of stationary object

Solution Approach 1:

The extension lamp socket employs a nested structure where the extension segment is positioned within or alongside the lampshade structure. The clamping segment can be nested within the extension segment, and the electrode holding ring is nested within the clamping segment. This nested arrangement allows the socket to provide extended volume for large bulbs while maintaining a compact overall form factor that fits within the lampshade's limited internal space.

Inventive Principle:
Principle #7Nested doll (Nesting)

AI summary

An extension lamp socket is disclosed and the extension lamp socket can be screwed into the screw connecting part of the conventional lamp socket for combination. The screw connector of a light bulb can be screwed in from the bottom end of the shell wall of the extension lamp socket and be fixed with the internal threaded convex body. In this way, the power source of the conventional lamp socket can be connected with the light bulb via the extension lamp socket. When installing a light bulb that occupies a large space, the extension lamp socket can be used to lower the screw connecting position. When installing a light bulb in a narrow or special space, the extension lamp socket can be used to extend the screw connecting position outward to facilitate installation of the light bulb.
