Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If LED filament arrangements use uniform sections emitting identical light characteristics, then manufacturing is simple and reliable, but decorative lighting patterns cannot be achieved

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoiddecorative lighting capability
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The LED filament is divided into multiple discrete sections, each capable of independent light emission with controllable characteristics. This segmentation allows different sections to emit different color temperatures and intensities, enabling decorative lighting patterns while maintaining standardized manufacturing processes for each section

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different sections of the LED filament are configured with distinct light emission properties (color temperature, intensity) to create varied decorative effects in different spatial locations. This local differentiation enables the filament to produce complex lighting patterns without requiring completely custom manufacturing for the entire device

Inventive Principle:
Principle #3Local quality

2Device complexity

If LED filament sections are arranged in traditional linear configurations, then structural simplicity is maintained, but decorative light patterns are limited

Engineering Contradiction:
Improvestructural simplicityVSAvoidlight pattern variety
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent introduces spatial arrangement dimensions beyond simple linear sequences by positioning sections in three-dimensional space with specific orientations. Sections are arranged adjacently and partially parallel to each other, creating multi-dimensional light emission patterns that enhance decorative capability while maintaining relatively simple structural implementation

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

3Use of energy by moving object

If all LED sections emit identical color temperature and intensity, then energy consumption is optimized for uniform illumination, but aesthetic appeal and decorative effects are reduced

Engineering Contradiction:
Improveenergy efficiencyVSAvoidaesthetic lighting quality
Core Design Contradiction:
Use of energy by moving objectVSIllumination intensity

Solution Approach 1:

The LED filament system enables dynamic control of light emission characteristics across different sections, allowing adjustment of color temperature and intensity independently for each section. This dynamic capability permits energy-efficient operation in uniform illumination mode while also enabling aesthetically pleasing decorative patterns when visual appeal is the priority

Inventive Principle:
Principle #15Dynamics
