Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional fixed light sources are used, then the structure is simple, but the adaptability to various lighting needs is limited
Solution Approach 1:
The illumination system is divided into multiple independent luminaire modules, each capable of being positioned and oriented separately. This segmentation allows each module to be independently adjusted to meet different lighting needs while maintaining overall system simplicity through modular design.
Solution Approach 2:
The luminaire modules are equipped with adjustable mounting mechanisms that enable dynamic repositioning and reorientation. This dynamic capability allows the system to adapt to various lighting configurations without requiring a completely different fixed structure for each application.
2Adaptability or versatility
If fixed positioning options are used, then the device complexity is reduced, but the ability to direct light into specific angular ranges is restricted
Solution Approach 1:
Adjustable mounting mechanisms with multiple degrees of freedom enable each luminaire module to be positioned and oriented at various angles. This dynamic positioning capability allows precise control over light direction into specific angular ranges while maintaining a relatively simple mounting structure.
Solution Approach 2:
The mounting mechanisms are designed to provide universal positioning capabilities that can direct light into multiple angular ranges using the same hardware platform. This multi-functionality achieves versatile light direction control without requiring complex specialized mechanisms for each angle.
3Use of energy by moving object
If traditional light sources are used, then the illumination intensity is sufficient, but the energy efficiency is poor
Solution Approach 1:
The patent transitions from traditional incandescent light sources to LED light sources, representing a fundamental parameter change in the illumination technology. This change dramatically improves energy efficiency while maintaining or enhancing illumination intensity, as LEDs convert electrical energy to light more efficiently than incandescent bulbs.
Solution Approach 2:
The patent replaces the thermal radiation mechanism of incandescent bulbs with the electroluminescence mechanism of LEDs. This substitution eliminates the inefficient heating process and directly converts electrical energy to light, achieving superior energy efficiency while preserving illumination intensity.
