Engineering Contradictions & Design Principles

VSEngineering 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

Engineering Contradiction:
Improveoperation stabilityVSAvoidmobile ions
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

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

Inventive Principle:
Principle #2Taking out (Extraction)

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

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If ion attraction units are added to reduce mobile ions, then interference is reduced, but device complexity increases

Engineering Contradiction:
Improveoperation stabilityVSAvoidstructure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

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

Inventive Principle:
Principle #5Merging (Combining)

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

Inventive Principle:
Principle #6Universality (Multi-functionality)
