Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple color light sources are used for detection, then detection accuracy is improved, but device complexity and cost increase
Solution Approach 1:
The patent changes the parameter of light color from being determined by multiple separate light sources to being determined by the voltage applied to LCD lenses. By varying the voltage, the LCD lenses display different colors (red, green, blue, yellow, white, etc.), allowing a single white light source to effectively become multiple color light sources through parameter modulation.
Solution Approach 2:
The patent introduces LCD lenses as an intermediary component between the white light source and the display panel being tested. The LCD lenses act as a mediator that modulates the color of light by displaying different colors based on applied voltage, thereby enabling color-specific detection without requiring multiple physical light sources.
2Measurement precision
If multiple color light sources are used for detection, then detection accuracy is improved, but detection efficiency decreases
Solution Approach 1:
The patent makes the light color dynamic by using LCD lenses that can rapidly switch between different colors based on applied voltage. This dynamic color switching allows the system to quickly change detection wavelengths without the mechanical complexity of switching between multiple light sources, thereby improving detection efficiency while maintaining accuracy.
Solution Approach 2:
The patent uses voltage parameter changes to control the color displayed by LCD lenses, enabling rapid and efficient switching between different detection colors. This parameter-based control method is more efficient than physical switching of multiple light sources, as it eliminates mechanical switching delays and complex control mechanisms.
3Measurement precision
If multiple color light sources are used for detection, then detection accuracy is improved, but apparatus cost increases
Solution Approach 1:
The patent makes the LCD lenses multi-functional by enabling them to display multiple colors (red, green, blue, yellow, white, and various grayscales) with a single component. This universal color-display capability replaces the need for multiple specialized light sources, significantly reducing apparatus cost while maintaining the ability to perform accurate color-specific detection.
Solution Approach 2:
The patent merges the functions of multiple color light sources into a single white light source combined with LCD lenses. By combining these elements, the system achieves the functional equivalence of multiple light sources while reducing the total number of components, simplifying manufacturing, and lowering overall apparatus cost.
