Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional LED lighting devices use color filters or filters with light permeable holes to express desired shapes and colors, then the atmosphere expression capability is improved, but the device complexity increases and design freedom is limited
Solution Approach 1:
The patent replaces mechanical filter systems with an optical member that uses refraction and reflection to achieve the same atmosphere expression effect. The optical member with specific refractive index and patterned surface replaces the need for physical color filters and light permeable hole filters, thereby reducing device complexity while maintaining adaptability.
Solution Approach 2:
The patent changes the optical parameters of the base substrate by controlling its refractive index within a specific range (1.3 to 1.8) and designing specific surface patterns. This parameter optimization allows the optical member to directly generate desired light shapes and colors without additional mechanical filters, resolving the contradiction between versatility and complexity.
2Manufacturing precision
If conventional LED lighting devices use intricate configurations to achieve desired shapes and colors, then the optical image quality is improved, but the ease of manufacture and installation deteriorates
Solution Approach 1:
The patent merges the functions of light shaping, color filtering, and atmosphere expression into a single integrated optical member. This consolidation eliminates the need for multiple separate components and intricate configurations, thereby improving ease of manufacture while maintaining high optical image quality through the optimized refractive index and surface patterns.
Solution Approach 2:
The optical member is designed to perform multiple functions simultaneously: it shapes light into desired patterns, filters colors through its material properties, and creates atmospheric effects through refraction and reflection. This multi-functionality in a single component simplifies manufacturing while achieving superior optical image quality.
3Measurement precision
If conventional LED lighting devices use multiple components to achieve desired light shapes, then the light control precision is improved, but the ease of operation and maintenance deteriorates
Solution Approach 1:
The patent extracts and eliminates unnecessary intermediate components from the lighting system, retaining only the essential optical member that directly achieves light control. This extraction maintains precise light control capability while significantly improving ease of operation and maintenance by reducing the number of components that require handling and servicing.
