Solution Overview

Problem

Existing string light installations face issues with uneven light distribution due to limitations in connecting light bodies whose length exceeds the length of the lampshade, leading to suboptimal lighting effects.

Innovation Solution

A light body connecting structure is introduced, featuring a wiring terminal with a terminal body, wiring plugs, and a connecting piece that allows for alignment and docking with the lampshade, enabling longer light body lengths and improved light uniformity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If terminals are inserted into lampshade openings for connection, then assembly is simplified, but the light body length is limited to the lampshade length

Engineering Contradiction:
Improveassembly simplicityVSAvoidlight body length
Core Design Contradiction:
Ease of manufactureVSLength of moving object

Solution Approach 1:

The connecting structure is divided into a terminal body and a connecting piece as separate functional segments. The terminal body remains outside the lampshade while the connecting piece interfaces with the opening, allowing the light body to extend beyond the lampshade length while maintaining simple assembly through the threaded connection mechanism.

Inventive Principle:
Principle #1Segmentation

2Reliability

If terminals are screwed into lampshade openings, then connection stability is improved, but light uniformity deteriorates due to limited light body length

Engineering Contradiction:
Improveconnection stabilityVSAvoidlight uniformity
Core Design Contradiction:
ReliabilityVSIllumination intensity

Solution Approach 1:

The connecting structure extends the light body in the longitudinal dimension beyond the lampshade boundaries. By positioning the terminal body outside the lampshade while maintaining threaded connection stability, the light body length is increased to enable more uniform light distribution across the illumination area.

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

3Measurement precision

If the terminal body size is larger than the lampshade opening, then alignment precision is improved, but the terminal cannot be inserted into the opening

Engineering Contradiction:
Improvealignment precisionVSAvoidinsertability
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The terminal is segmented into a terminal body (larger size for alignment) and a connecting piece (smaller size for insertion). The connecting piece with reduced dimensions can pass through the lampshade opening while the larger terminal body remains outside, achieving both precise alignment and easy insertability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The connecting piece is nested within or attached to the terminal body, forming a composite structure where the smaller inserting portion is contained within or connected to the larger alignment portion. This nested arrangement allows the structure to function both as a precise alignment element and an insertable component.

Inventive Principle:
Principle #7Nested doll (Nesting)

AI summary

A light body connecting structure, a light body and a string light are provided. The light body connecting structure includes a wiring terminal (1) and a wire (2). The wiring terminal (1) includes a terminal body (11) and at least one wiring plug (12). At least one mounting groove (111) is defined on the terminal body (11) for accommodating the at least one wiring plug (12). The terminal body (11) is detachably connected to the lampshade (4). When the terminal body (11) is connected to the lampshade (4), the at least one wiring plug (12) is aligned with the opening (412) of the lampshade (4). When the light body connecting structure is connected to the lampshade (4), the at least one wiring plug (12) is disposed outside the opening (412) and aligns with the opening (412), so a length of the light body (3) is allowed to be long and light emitted by the light body (3) is bright and uniform.
