Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If LED modules are used for illumination, then energy efficiency and lifetime are improved, but light quality and pattern generation flexibility are insufficient
Solution Approach 1:
A light passing cover is introduced as an intermediary component between the LED modules and the external environment. This cover includes a curved surface that refracts and diffuses the light emitted by LED modules, transforming the harsh direct light into softer, more versatile light patterns while maintaining the energy efficiency benefits of LED technology
Solution Approach 2:
The curvature radius of the light passing cover is optimized to be between 0.25 to 0.75 times the diameter of the cover. This parameter optimization changes the light transmission characteristics, enabling the system to produce diverse light patterns and improve light quality while maintaining the low energy consumption of LED sources
2Illumination intensity
If a curved light passing cover is used to improve light distribution, then light quality is improved, but manufacturing precision requirements increase
Solution Approach 1:
Instead of requiring complex free-form curved surfaces, the patent specifies a circular curved surface with a controlled curvature radius ratio (0.25 to 0.75 times the diameter). This parameterization simplifies the manufacturing process while still achieving the desired light diffusion and quality improvement, making the curved cover more manufacturable
3Object-affected harmful factors
If transparent insulation layer with micro particles is added for electrical safety, then safety from electrical shocks is improved, but device complexity increases
Solution Approach 1:
The transparent insulation layer is created by incorporating micro particles into a transparent material matrix. This composite structure provides electrical insulation and safety from electrical shocks while maintaining transparency for light transmission. The micro particles dispersed in the transparent material create the insulation properties without requiring separate complex insulation components
Solution Approach 2:
The transparent insulation layer combines multiple functions into a single component: electrical insulation for safety, transparency for light transmission, and structural integration with the light passing cover. This merging reduces the overall device complexity by eliminating the need for separate insulation layers and safety components
4Ease of operation
If detachable design is implemented for easy installation, then ease of operation is improved, but reliability of electrical connection may worsen
Solution Approach 1:
The lighting apparatus is divided into detachable modules including the light passing cover, transparent insulation layer, and LED module assembly. This segmentation allows for easy installation and maintenance while standardized connection interfaces ensure reliable electrical connections are maintained despite the detachable nature of the components
