Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual injection method is used to charge liquids into cavity, then complete charging without air bubbles can be achieved, but production time is increased and productivity is reduced
Solution Approach 1:
The patent replaces the manual mechanical injection process with an automated liquid charging apparatus that uses electrical control mechanisms. The apparatus includes a charging needle positioned through a seal member, controlled by a controller to automatically charge liquids into the cavity without manual intervention, thereby maintaining complete charging without air bubbles while significantly reducing production time and increasing productivity
Solution Approach 2:
The liquid charging apparatus is designed to automatically control the charging process without continuous manual operation. The controller manages the positioning of the charging needle, the injection of liquids, and the sealing process, allowing the system to perform the charging operation autonomously and efficiently, thus improving productivity while ensuring complete liquid charging without air bubbles
2Device complexity
If interface position adjustment is not optimized, then liquid lens structure is simple, but optical performance and functionality are compromised
Solution Approach 1:
The patent segments the liquid lens into distinct functional components: a first liquid (conductive or non-conductive), a second liquid (with different refractive index), a seal member, and an interface position adjustment mechanism. This segmentation allows independent optimization of each component, enabling precise control over the interface between liquids to achieve desired optical performance while maintaining a manageable overall structure
Solution Approach 2:
The patent incorporates an interface position adjustment mechanism that enables dynamic control of the interface between the first and second liquids. This dynamic adjustment capability allows the liquid lens to adapt its optical properties by changing the interface position, thereby achieving variable focal length or other optical functions while maintaining a relatively simple base structure, thus balancing device complexity with optical performance and functionality
