Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manufacturing processes for liquid crystal antennas often result in regional differences in cell gaps due to variations in film thickness, leading to substrate deformation and inaccurate measurement of cell gaps, which can cause interpretation errors and failure to meet specifications.
Innovation Solution
An electromagnetic wave adjusting device with a working region and a non-working region, where the non-working region has the same film-layer stack structure as the working region, allowing for accurate measurement of cell gaps by minimizing the impact of different film-layer stack structures and ensuring consistent deformation measurement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the same amount of liquid crystal material is filled into the space for accommodating the liquid crystal material, then the manufacturing process is simplified, but the substrate deforms due to space reduction, resulting in regional differences in cell gap
Solution Approach 1:
The patent applies preliminary action by designing a compensation mechanism that pre-adjusts for the space reduction caused by film thickness variation. The compensation liquid crystal material quantity is calculated in advance based on the relationship between film thickness and accommodating space, allowing the cell gap to be maintained at the target value despite manufacturing variations.
Solution Approach 2:
The patent changes the parameter of liquid crystal material quantity based on film thickness measurements. By establishing a correspondence between film thickness values and required liquid crystal material quantities, the system dynamically adjusts the filling amount to compensate for space changes, thereby maintaining consistent cell gap across different regions.
2Measurement precision
If cell gaps are measured in different regions of the liquid crystal antenna, then the accuracy of quality assessment is improved, but the measurement time and complexity increase
Solution Approach 1:
The patent extracts the measurement function from multiple regions and consolidates it to a single measurement point. By demonstrating that measuring the cell gap at one location is sufficient to represent the entire antenna when the compensation mechanism is properly implemented, the system eliminates the need for multiple regional measurements while maintaining quality assessment accuracy.
Solution Approach 2:
The patent establishes a universal measurement approach where a single cell gap measurement can serve as the basis for assessing the entire antenna structure. The compensation mechanism ensures that the cell gap relationship remains consistent across regions, making one measurement point representative of the whole device.
3Measurement precision
If multiple measurement points are used to determine cell gap differences, then the detection accuracy is improved, but the device complexity and measurement difficulty increase
Solution Approach 1:
The patent extracts the essential measurement requirement from a multi-point measurement system and reduces it to a single-point measurement. By proving that the compensation mechanism maintains consistent cell gap relationships across regions, the system eliminates the complexity of multiple measurement points while retaining the ability to accurately detect cell gap characteristics.
