Solution Overview

Problem

Existing LED filament bulbs cannot have a full glass design due to the need for a transition connector for the power source, limiting their ability to provide high-quality illumination in areas requiring omnidirectional light emission.

Innovation Solution

A wick lamp design featuring a lamp rail that can be bent into different shapes, enclosed by an insulating layer with parallel conducting wires and welded LED light emitters, allowing for omnidirectional light emission by diffusing light over 360°.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If LED bulbs use a transition connector for power source, then electrical connection is achieved, but full glass design cannot be implemented

Engineering Contradiction:
Improvefull glass designVSAvoidconnector structure
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent combines the electrical connection function directly into the glass structure by forming conducting wires within the glass body itself, eliminating the need for separate transition connectors. The glass is transformed from a simple enclosure to an integrated electrical component, merging structural and electrical functions into a single element.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent extracts the transition connector from the overall structure and eliminates it entirely by integrating the electrical connection function directly into the glass bulb through embedded conducting wires, simplifying the device structure while maintaining functionality.

Inventive Principle:
Principle #2Taking out (Extraction)

2Illumination intensity

If LED light emitters are arranged on lamp rail, then light emission is achieved, but omnidirectional light distribution is limited

Engineering Contradiction:
Improvelight distributionVSAvoidlight emission efficiency
Core Design Contradiction:
Illumination intensityVSProductivity

Solution Approach 1:

The patent transitions from traditional unidirectional or bidirectional LED arrangement to a three-dimensional omnidirectional configuration. LED light emitters are positioned on the lamp rail to emit light in multiple directions simultaneously, utilizing spatial dimensionality to achieve 360-degree illumination coverage rather than linear light distribution.

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

Solution Approach 2:

The patent employs a colloid layer that undergoes optical phase transition to diffuse and redirect light from the LED emitters, transforming the directional light output into omnidirectional distribution. The colloid material modifies the light propagation path through scattering and refraction, achieving uniform light distribution in all directions.

Inventive Principle:
Principle #36Phase transitions

3Reliability

If conducting wires are exposed for electrical connection, then power transmission is achieved, but safety and insulation are compromised

Engineering Contradiction:
Improveelectrical connectionVSAvoidelectrical shock risk
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent embeds the conducting wires within the glass structure, creating a nested configuration where the glass enclosure contains and protects the electrical conductors. The insulating layer is integrated within the glass wall structure, forming a nested insulation system that protects exposed electrical components while maintaining compact design.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The patent creates a composite structure combining glass, conducting wires, and insulating materials into an integrated system. The glass serves both structural and insulation functions, while the insulating layer provides additional electrical protection. This composite approach achieves reliable electrical connection while eliminating shock hazards through material integration.

Inventive Principle:
Principle #40Composite materials
