Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If frequent changes of light sources are made to meet different pre-tilt angle requirements, then different light source intensities can be achieved, but productivity decreases due to time waste from adjustments
Solution Approach 1:
The patent changes the parameter of light transmittance by introducing a lighting baffle with adjustable transmittance properties. Instead of changing light sources, the system maintains a fixed light source and adjusts the baffle's light transmittance parameter to achieve different exposure intensities for different pre-tilt angle requirements
Solution Approach 2:
The lighting baffle acts as an intermediary component between the light source and the main substrate. It mediates the light transmission by controlling light transmittance, allowing flexible adjustment of exposure intensity without requiring changes to the light source itself
2Adaptability or versatility
If light sources are frequently changed and equipment is adjusted, then different exposure intensities can be achieved, but material waste increases
Solution Approach 1:
The system adjusts the light transmittance parameter of the lighting baffle to achieve different exposure intensities, eliminating the need for frequent light source changes and reducing material waste from failed production runs
Solution Approach 2:
The lighting baffle is pre-configured with specific transmittance properties to match required exposure intensities. This preliminary preparation allows direct use without frequent adjustments, reducing material waste from trial-and-error production
3Device complexity
If the same light source is used for multiple display panels, then equipment complexity is reduced, but manufacturing precision decreases due to inability to optimize exposure intensity for each panel
Solution Approach 1:
The lighting baffle serves as an intermediary that enables precise control of exposure intensity for each display panel type while using a single light source. It allows the system to maintain both equipment simplicity and manufacturing precision
Solution Approach 2:
Different lighting baffles with specific transmittance parameters are selected or configured for different display panel types, enabling precise optimization of exposure intensity for each panel while keeping the light source configuration simple
