Engineering Contradictions & Design Principles
Engineering 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
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
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
2Device complexity
If LED filament sections are arranged in traditional linear configurations, then structural simplicity is maintained, but decorative light patterns are limited
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
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
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
