Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional dispensing or spraying method is used for waterproofing LEDs, then waterproofing function is achieved, but coating time and coating solution consumption increase significantly
Solution Approach 1:
The patent applies preliminary action by pre-forming a molding part with a shape corresponding to the LEDs before the coating process. This molding part serves as a template or mask that guides the coating solution application, enabling precise and efficient waterproofing without requiring time-consuming conventional dispensing or spraying methods across the entire surface.
2Reliability
If conventional dispensing or spraying method is used for waterproofing LEDs, then waterproofing function is achieved, but coating solution consumption increases
Solution Approach 1:
The patent applies local quality by creating a molding part with a shape corresponding to the LEDs, which enables localized application of the coating solution only where needed (around the LEDs). This prevents waste of coating solution on areas that do not require waterproofing, thereby reducing overall coating solution consumption while maintaining effective waterproofing protection.
3Illumination intensity
If molding part with varying thickness is used, then light transmittance and contrast ratio are improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent applies local quality by designing the molding part with varying thickness - a first thickness in a first region and a second thickness in a second region. This variation in thickness creates different light transmittance properties in different areas, which improves contrast ratio and illumination characteristics. The localized thickness adjustment allows optimization of optical performance without requiring uniform precision across the entire molding part.
