String Lamp with Spike Terminals for RGB Color Variability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing string lamps lack the ability to emit variable colors of light, resulting in a poor decorative effect during festive seasons like Christmas.
Innovation Solution
The new string lamp design includes a power line with sequence-arranged string lamp bodies, each comprising a lamp cap part and a lamp bulb part, where the lamp cap part has metal terminals with spike-shaped penetrating parts for electrical conductivity, allowing for plug-in or screw-type lamp bulbs with RGB light sources that can emit variable colors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional single-color lamp bulbs are used, then the structure is simple and easy to manufacture, but the decorative effect is poor and cannot emit variable colors of light
Solution Approach 1:
The lamp bulb is divided into separate components: a lamp cap part containing metal terminals and a lamp bulb part containing the light-emitting source. This segmentation allows the light source to be replaced with different color configurations (single-color or RGB) while keeping the lamp cap structure simple and easy to manufacture.
Solution Approach 2:
The lamp cap part with metal terminals is designed as a universal component that can accommodate both traditional single-color lamp bulbs and modern RGB lamp bulbs. The metal terminals provide electrical connection for both types, enabling the same lamp structure to achieve both simplicity and color variability.
2Adaptability or versatility
If RGB light-emitting sources are used, then variable colors of light can be emitted for better decorative effect, but the structural complexity increases
Solution Approach 1:
The lamp is segmented into a lamp cap part and a lamp bulb part. The complex RGB light-emitting source is contained within the lamp bulb part, while the lamp cap part maintains a simple structure with only metal terminals and a plastic sheath, thus distributing complexity to a replaceable component.
Solution Approach 2:
The metal terminals act as an intermediary between the power line and the light-emitting source. They provide a simple electrical connection interface that works with both simple and complex light sources, reducing the overall structural complexity while enabling color variability.
3Reliability
If the power line penetrates through the lamp cap part with metal terminals, then electrical connection is achieved, but the plastic sheath of the power line may compromise electrical insulation
Solution Approach 1:
The metal terminals serve as an intermediary that bridges the power line and the light-emitting source. The terminals are electrically conductive and penetrate the plastic sheath to contact the line core, providing reliable electrical connection while the plastic sheath itself maintains its insulation function by not directly contacting the conductive elements.
Solution Approach 2:
The plastic sheath is designed with localized penetration points where metal terminals pass through to reach the line core. The majority of the plastic sheath retains its insulating properties, while only specific localized areas are modified for electrical connection, thus maintaining overall insulation reliability while achieving conductivity where needed.

The design enables the string lamp to emit variable colors of light, enhancing decorative effects while being novel in structural design and convenient for demounting and repair.
Implementation Method 1
The light-emitting source is provided with a plurality of light source pins. The lamp cap part is provided with an insertion part. The plastic core is inserted into the insertion part of the lamp cap part, and each light source pin of the light-emitting source contacts and is electrically conductive to a corresponding metal terminal.
