Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a TN display panel is used for light polarization, then high-definition images can be achieved, but image distortion and jittering occur due to sluggish twisting at low temperatures
Solution Approach 1:
The patent changes the temperature parameter of the display panel by controlling fluid flow through temperature regulator valves. The system adjusts the temperature of the TN display panel to maintain optimal twisting rates of liquid crystals, preventing image distortion and jittering while preserving high-definition image quality.
2Temperature
If the display apparatus operates in high temperature environments, then ambient temperature tolerance is improved, but overheating occurs causing damage to the display system
Solution Approach 1:
The patent implements a feedback control system where temperature sensors monitor the display panel temperature and send signals to the processor. The processor adjusts the temperature regulator valves accordingly to maintain temperature within safe operating ranges, preventing overheating damage while allowing operation in high ambient temperature environments.
Solution Approach 2:
The patent introduces fluid flow as an intermediary thermal management mechanism. Temperature regulator valves control the flow of cooling fluid through channels adjacent to the display panel, acting as a mediator to transfer heat away from the display system and prevent overheating.
3Object-affected harmful factors
If fluid flow is continuously supplied for cooling, then overheating is prevented, but energy consumption increases
Solution Approach 1:
The patent uses periodic action by only activating fluid flow cooling when temperature sensors detect elevated temperatures. The system alternates between cooling mode and normal operation mode, adjusting fluid flow through temperature regulator valves based on real-time temperature conditions, thereby preventing continuous energy consumption while maintaining effective overheating prevention.
