Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If radiation devices are operated for prolonged periods or undergo manufacturing processes, then the device functions, but mobile ions are generated causing interference to operation
Solution Approach 1:
The patent extracts and removes mobile ions from the liquid crystal layer by introducing an ion attraction unit with electrodes that generate electric fields to draw ions out of the liquid crystal material, thereby eliminating the harmful factor while preserving the radiation device's operational function
Solution Approach 2:
The patent introduces an ion attraction unit as an intermediary component between the liquid crystal layer and the external environment. This unit acts as a mediator that selectively attracts and removes ions without interfering with the primary radiation function of the device
2Reliability
If ion attraction units are added to reduce mobile ions, then interference is reduced, but device complexity increases
Solution Approach 1:
The patent merges the ion attraction function with the existing liquid crystal display structure by integrating electrodes and alignment layers into the existing substrate architecture. The ion attraction unit is combined with the liquid crystal layer formation process, allowing dual functionality without proportionally increasing complexity
Solution Approach 2:
The electrodes and alignment layers in the ion attraction unit serve multiple functions: they both control liquid crystal orientation for radiation phase adjustment and simultaneously attract mobile ions for removal. This multi-functionality reduces the need for separate dedicated ion removal components
