Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If power voltage is reduced to decrease power consumption, then energy efficiency improves, but image quality deteriorates
Solution Approach 1:
The patent implements dynamic power voltage adjustment by analyzing image content characteristics (such as brightness distribution and gray scale levels) and adapting the power voltage in real-time. The controller modifies the power voltage based on the actual image being displayed, using higher voltages for bright images and lower voltages for dark images, thus resolving the contradiction between power consumption and image quality maintenance
Solution Approach 2:
The system changes the power voltage parameter dynamically based on image content analysis. By converting digital image data to analog power voltage through a digital-to-analog converter, the system adjusts the voltage level proportionally to the image brightness requirements, enabling power consumption reduction without compromising image quality when appropriate
2Use of energy by moving object
If power voltage is adjusted in real-time based on image content, then power consumption is reduced, but device complexity increases
Solution Approach 1:
The controller performs multiple functions: it analyzes image content characteristics, determines appropriate power voltage levels, converts digital signals to analog voltage, and regulates power output. By consolidating these functions into a single control circuit board, the patent reduces overall system complexity despite adding real-time adjustment capabilities
Solution Approach 2:
The digital-to-analog converter serves as an intermediary component that bridges the digital image processing domain and the analog power regulation domain. This intermediary enables efficient communication and control between the controller and power generator, simplifying the overall control architecture while enabling real-time power adjustment
