Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the circuit system of the computer part is integrated with the circuit system of the display panel part, then the display panel becomes light and portable as a whole, but the whole intelligent display panel needs to be detected and repaired no matter the panel or the computer part fails, increasing maintenance cost and difficulty
Solution Approach 1:
The display system is divided into two independent subsystems: a host subsystem containing the computer circuit system and a panel subsystem containing the display panel circuit system. These subsystems are connected through pluggable board connectors, allowing physical separation while maintaining functional integration during operation. This segmentation enables independent maintenance of each subsystem without affecting the other.
2Ease of repair
If the display system allows plugging operations during maintenance, then ease of repair is improved, but electrical damage may occur during plugging operations
Solution Approach 1:
The plugging detection circuit activates automatically when connectors are plugged in, detecting the connection status before any power-on operations. The master control module receives this detection signal and only enables power supply after confirming proper connection, preventing electrical damage from premature power application during maintenance operations.
Solution Approach 2:
The system implements a feedback mechanism where the plugging detection circuit continuously monitors connector status and communicates with the master control module. This feedback loop ensures that power supply is dynamically controlled based on real-time connection status, preventing electrical damage while enabling maintenance operations.
3Speed
If the master control module sends power enable signal immediately upon receiving standby signal, then power-on speed is improved, but electrical safety is compromised during plugging operations
Solution Approach 1:
The plugging detection circuit performs connection verification in advance before the master control module enables power supply. This preliminary detection action ensures that the connectors are properly connected before any power is applied, maintaining both fast power-on response and electrical safety.
Solution Approach 2:
The system implements preliminary anti-action by detecting plugging status before power enablement, preventing the harmful effect of electrical damage. The master control module withholds power supply until the plugging detection circuit confirms proper connection, thereby counteracting potential electrical hazards before they can occur.
