Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional progressive lenses are used, then visual needs for various distances can be met, but it takes time for the wearer to get used to it
Solution Approach 1:
The patent applies dynamics by making the lens power adjustable and changeable based on real-time needs. The electronic device controls liquid crystal molecules to dynamically change the focal distance and lens power, allowing the wearer to switch between different viewing distances instantly without the gradual adaptation required by traditional progressive lenses.
Solution Approach 2:
The patent changes the parameter of lens power dynamically. By controlling the voltage applied to the liquid crystal molecules, the focal distance and diopter values can be adjusted in real-time. This allows the lens to adapt to different visual needs instantly, eliminating the adjustment time problem of traditional progressive lenses.
2Adaptability or versatility
If Fresnel lens structure is used for focal distance adjustment, then focal distance can be changed, but the Fresnel lens structure becomes visibly apparent
Solution Approach 1:
The patent replaces the mechanical Fresnel lens structure with an electronic control system. Instead of using physical lens structures to change focal distance, the invention uses voltage-controlled liquid crystal molecules to achieve the same function. This substitution eliminates the visible mechanical structure while maintaining the focal distance adjustment capability.
Solution Approach 2:
The patent changes from a fixed mechanical lens structure to a dynamically controllable electronic system. By adjusting the voltage parameter, the focal distance can be changed without any visible structural changes. The liquid crystal molecules respond to voltage changes, allowing smooth, invisible transitions between focal distances.
3Ease of manufacture
If fixed lens power is used, then manufacturing is simple, but the lens power cannot be adjusted according to actual situation
Solution Approach 1:
The patent transforms the fixed lens power into a dynamic, adjustable system. The electronic device enables real-time control of lens power through voltage application to liquid crystal molecules. This allows the same lens to adapt to different viewing conditions and personal needs without requiring multiple fixed lenses or complex manufacturing processes.
Solution Approach 2:
The patent creates a universal lens system that can serve multiple functions. A single lens with adjustable electronic control can replace multiple fixed lenses for different focal distances and power requirements. The liquid crystal-based control system allows one lens to perform the function of several specialized lenses.
