Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If traditional Tungsten filament bulbs are replaced with LED technology, then luminous efficacy is improved, but decorative features are lost
Solution Approach 1:
The patent uses an optical light guide to create enlightened patterns that copy the visual appearance of traditional Tungsten filament bulbs. The light guide transforms LED light into patterns resembling filament structures, allowing LED bulbs to replicate the decorative aesthetic of traditional bulbs while maintaining LED energy efficiency
Solution Approach 2:
The patent employs multiple LED modules with different color temperatures (warm white, cool white, yellow, blue, green, red) to create various light effects and patterns. This allows the bulb to provide diverse decorative appearances while maintaining high luminous efficacy, resolving the contradiction between energy efficiency and decorative versatility
2Use of energy by moving object
If advanced LED technology is used to replace traditional bulbs, then luminous efficacy is improved, but cost increases
Solution Approach 1:
The optical light guide serves multiple functions: it guides light from LED modules, creates decorative enlightened patterns, and acts as a heat dissipation structure. This multi-functionality reduces the need for separate components, simplifying manufacturing and reducing costs while maintaining advanced LED technology benefits
Solution Approach 2:
The patent combines multiple LED modules and optical light guide structures into an integrated assembly. The connector integrates the LED plate and optical light guide, reducing assembly steps and manufacturing complexity, thereby lowering production costs while preserving high luminous efficacy
3Adaptability or versatility
If multiple LED modules with independent control are added, then decorative versatility is improved, but device complexity increases
Solution Approach 1:
The optical light guide acts as an intermediary that simplifies the system by consolidating light guidance and pattern formation functions. Instead of requiring complex individual control mechanisms for each LED module, the light guide uniformly distributes and shapes light from multiple modules, reducing control complexity while maintaining decorative versatility
Solution Approach 2:
The patent divides the lighting system into independent LED modules that can be controlled separately, yet they work together through the unified optical light guide structure. This segmentation allows for versatile light effects while the modular design simplifies manufacturing and maintenance, offsetting the increased device complexity
