Innovation Solution
A driver IC with a signal generation module that adjusts current intensities of driving signals based on the lengths of transmission wires, providing different driving capabilities to match specific requirements rather than maximum capabilities, thereby reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the driver IC provides maximum driving capability to all signal transmission lines, then all transmission lines can be driven reliably, but the power consumption increases
Solution Approach 1:
The patent applies local quality by providing different current intensities to different signal transmission lines based on their specific characteristics. The driver IC includes multiple current intensity adjustment circuits that can independently adjust the driving current for each transmission line, ensuring that lines with longer lengths or higher load requirements receive higher current while shorter lines receive lower current, thus optimizing power consumption while maintaining reliable driving for all lines
Solution Approach 2:
The patent implements dynamics by making the current intensity adjustable and adaptable. The driver IC includes control circuits that can dynamically adjust the current intensity for each transmission line based on real-time requirements, allowing the system to adapt to different operating conditions and minimize power consumption while ensuring reliable signal transmission
2Adaptability or versatility
If multiple driver ICs are arranged to drive different signal transmission lines, then comprehensive coverage is achieved, but the device complexity and power consumption increase
Solution Approach 1:
The patent applies universality by designing a driver IC that can drive multiple signal transmission lines with different characteristics using a single integrated circuit. The driver IC includes multiple output channels, each with independent current intensity adjustment capabilities, allowing one driver IC to replace multiple separate driver ICs while maintaining the ability to provide customized driving parameters for each transmission line
Solution Approach 2:
The patent implements merging by combining multiple driver functions into a single driver IC. The integrated circuit includes multiple current intensity adjustment circuits and control logic that work together to manage multiple transmission lines, reducing the overall number of components and simplifying the device structure while maintaining comprehensive signal transmission coverage
