Three-Part Lens Fixation Fixture for Uniform Liquid Crystal Thickness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional heating equipment fails to effectively fix liquid crystals and solid-state lenses during the manufacturing of liquid crystal lenses, leading to uneven thickness and improper arrangement of liquid crystals, which affects the quality and performance of the lenses.
Innovation Solution
A fixation fixture comprising a lower, middle, and upper fixture is used to securely hold transparent curved substrates and a liquid crystal layer, ensuring precise alignment and stable positioning during the manufacturing process, utilizing thermal conductivity and heat resistance materials like metal for high-temperature processing.

Engineering Contradiction Analysis
1Manufacturing precision
If conventional heating equipment is used to process liquid crystal lenses, then the manufacturing process can be completed, but the liquid crystal cannot be neatly arranged in specific positions and the thickness becomes uneven
Solution Approach 1:
The fixation fixture is divided into three separate components: lower fixture, middle fixture, and upper fixture. This segmentation allows each component to perform specific functions - the lower and upper fixtures provide stable support while the middle fixture applies targeted pressure to the liquid crystal layer, enabling precise positioning and uniform thickness without compromising fixation reliability.
Solution Approach 2:
The middle fixture acts as an intermediary component between the lower and upper fixtures. It transmits and distributes pressure uniformly across the liquid crystal layer, ensuring neat arrangement and consistent thickness while maintaining the overall fixation structure's reliability.
2Adaptability or versatility
If conventional heating equipment is used, then heating can be applied, but concave and convex lenses cannot be fixed properly
Solution Approach 1:
The fixation fixture is designed with universal applicability to accommodate different lens types including concave, convex, and flat lenses. The three-component structure with adjustable positioning features allows the same fixture to adapt to various lens curvatures and sizes, providing both versatility and precise fixation for all lens types.
Solution Approach 2:
The fixture incorporates dynamic adjustment capabilities that allow it to adapt to different lens geometries. The middle fixture can be positioned and adjusted to apply appropriate pressure distribution for each lens type, maintaining fixation precision across diverse lens configurations.

AI summary
A fixation fixture includes a lower fixture, a middle fixture, and an upper fixture. The lower fixture includes a loading stage for carrying an object. The middle fixture is removably installed on the lower fixture and defines a through hole to expose the loading stage. A retaining edge extends from wall of the through hole. The upper fixture is removably installed on the middle fixture and extends in the through hole. A processing device and a method for making a liquid crystal lens are also provided.
