Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If blue light is reduced through hardware filters or anti-blue-light coatings, then blue light radiation is reduced, but device cost increases
Solution Approach 1:
The patent adjusts the color temperature parameter of the display screen through software control to shift the spectral distribution of emitted light. By dynamically changing color temperature parameters (e.g., from 6504K to lower values), the system reduces blue light content without requiring physical filters or coatings, thereby avoiding additional manufacturing costs while achieving eye protection functionality.
2Object-affected harmful factors
If blue light is reduced through hardware filters or coatings, then blue light radiation is reduced, but device complexity increases
Solution Approach 1:
The patent replaces physical hardware solutions (filters, coatings, or additional optical components) with a software-based color temperature adjustment mechanism. By using image processing algorithms to modify pixel output values and adjust color temperature parameters, the system achieves blue light reduction without adding mechanical or optical components, thus maintaining device structural simplicity.
3Object-affected harmful factors
If color temperature is adjusted to reduce blue light, then blue light radiation is reduced, but image quality may deteriorate
Solution Approach 1:
The patent implements dynamic color temperature adjustment that adapts to different usage scenarios, times of day, and content types. The system can switch between different color temperature modes (e.g., warm mode for nighttime, standard mode for daytime) and dynamically balance between blue light reduction and image quality preservation, allowing users to select appropriate modes based on their needs while maintaining overall image fidelity.
