Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional physical characteristics are used for vision correction, then the lens structure is simple, but the lens cannot dynamically adjust to varying vision needs for different distances
Solution Approach 1:
The patent applies the dynamics principle by incorporating an arcuate shaped liquid meniscus lens that can dynamically change its shape between different states (first state for distance vision, second state for near vision) based on user needs. This dynamic shape change capability allows the lens to adapt to varying vision requirements, transforming a static optical system into a dynamic one that can adjust its optical properties in real-time.
Solution Approach 2:
The patent utilizes the pneumatics and hydraulics principle by employing a liquid meniscus lens that changes shape through fluid manipulation. The liquid meniscus can be reconfigured between different curvature states using pneumatic or hydraulic actuation mechanisms, enabling dynamic adjustment of the lens optical power without mechanical moving parts that would complicate the structure.
2Adaptability or versatility
If multi-focal vision correction is implemented, then vision correction for different distances is achieved, but the programming and control system becomes more complex
Solution Approach 1:
The patent applies the parameter changes principle by programmatically controlling the liquid meniscus lens to change its physical parameters (shape, curvature) between defined states. The microprocessor system stores and executes programming instructions that correspond to different vision correction needs, dynamically adjusting lens parameters such as optical power and focal length to provide multi-focal correction for both near and distance vision.
Solution Approach 2:
The patent implements the self-service principle through an automated control system that can independently manage the liquid meniscus lens configuration. The microprocessor and communication system work together to automatically adjust the lens state based on programmed instructions, reducing the need for manual intervention and enabling the lens to self-regulate its optical properties for different viewing distances.
3Adaptability or versatility
If variable liquid meniscus lenses are used, then on-demand vision correction is possible, but the lens geometry and manufacturing become more difficult
Solution Approach 1:
The patent applies the segmentation principle by dividing the lens into distinct functional components: a hydrogel contact lens portion and a separate arcuate shaped liquid meniscus lens layer. This segmentation allows each component to be manufactured using optimized processes for its specific function, with the liquid meniscus layer being applied or integrated onto the hydrogel base, simplifying the overall manufacturing complexity despite the variable geometry requirements.
