Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a lamp is used as an extra light source in poor-lit environments, then illumination is improved, but glare and color distortion occur
Solution Approach 1:
The system uses optical sensors to detect ambient light parameters and feeds this information back to the controller, which automatically adjusts the lamp brightness and screen display parameters to prevent glare while maintaining adequate illumination
Solution Approach 2:
The system dynamically changes the brightness and color temperature parameters of both the lamp and screen based on detected ambient light conditions, optimizing illumination while avoiding harmful glare effects
2Manufacturing precision
If manual adjustment of brightness and color is required, then display quality can be optimized, but user convenience deteriorates
Solution Approach 1:
The system performs self-adjustment of display parameters and lamp brightness automatically based on sensor input, eliminating the need for manual user intervention while maintaining optimal display quality
Solution Approach 2:
The controller continuously monitors ambient light conditions through optical sensors and automatically adjusts display parameters accordingly, creating a closed-loop system that maintains optimal quality without user effort
3Measurement precision
If luminometer and colorimeter are used to monitor adjustments, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The system combines the functions of luminometer and colorimeter into a single integrated optical sensor module that simultaneously measures both brightness and color temperature, reducing device complexity while maintaining measurement precision
Solution Approach 2:
The optical sensor serves multiple functions by detecting both ambient light intensity and color temperature parameters, eliminating the need for separate dedicated measurement devices
