Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the potential regulator operates within its fixed regulation range, then the device complexity is low and operation is simple, but it cannot effectively compensate when potential deviation exceeds the regulation range
Solution Approach 1:
The patent implements dynamic adjustment of the potential regulator's reference voltage range. The controller dynamically calculates a compensation value based on the detected potential deviation and adjusts the reference voltage accordingly, enabling the regulator to adapt to potential deviations beyond its original fixed range. This transforms the static regulation system into a dynamic one that can handle varying compensation needs.
Solution Approach 2:
The patent changes the parameter of reference voltage in the potential regulator. By adjusting the reference voltage parameter dynamically based on the detected potential deviation, the system expands its effective regulation range. The controller modifies the reference voltage parameter to ensure the compensation value falls within the regulator's adjustable range, thereby maintaining compensation effectiveness for larger deviations.
2Adaptability or versatility
If the potential regulator's range is expanded to cover larger potential deviations, then the adaptability improves, but the device complexity and control difficulty increase
Solution Approach 1:
The patent implements a feedback mechanism where the potential detecting IC continuously monitors the actual potential of the display panel and feeds this information back to the controller. The controller uses this feedback to calculate the deviation from the standard potential and dynamically adjusts the reference voltage accordingly. This closed-loop feedback system enables automatic adaptation without requiring complex manual intervention or additional hardware.
Solution Approach 2:
The system performs self-adjustment through automatic calculation and regulation. The controller automatically calculates the compensation value based on the detected deviation and adjusts the reference voltage without external intervention. This self-service capability reduces the need for complex external control mechanisms while achieving the desired expansion of regulation range.
3Adaptability or versatility
If the potential regulator's range is expanded to cover larger potential deviations, then the adaptability improves, but the difficulty of detecting and measuring increases
Solution Approach 1:
The patent introduces a potential detecting IC as an intermediary component that simplifies the detection process. This dedicated sensing component is specifically designed to measure the potential of the display panel and provide accurate feedback to the controller. By using this intermediary detection device, the system achieves reliable measurement of potential deviations without requiring complex measurement circuits or procedures.
