Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional color filtering materials are used in contact lenses, then color vision deficiency management is achieved, but optical transmission is reduced and effectiveness is limited
Solution Approach 1:
The patent combines MXene nanomaterials with contact lens materials to create a composite structure that filters specific wavelengths while maintaining high optical transmission. The MXene material is dispersed within the lens matrix at controlled concentrations to achieve selective wavelength filtration without compromising overall transparency
Solution Approach 2:
The invention applies wavelength-selective filtering at specific regions of the spectrum rather than uniformly across all wavelengths. The MXene material is engineered to target specific wavelength ranges (e.g., 540-580 nm for red-green CVD) while allowing other wavelengths to pass through, creating localized optical properties
2Reliability
If existing CVD contact lens designs are implemented, then some color filtration is achieved, but cost and scalability are limited
Solution Approach 1:
The patent utilizes the tunable optical properties of MXene materials by adjusting composition ratios, particle size, and concentration levels to achieve different filtration profiles. This allows customization for various types of color vision deficiencies while maintaining a scalable manufacturing approach through material parameter optimization
Solution Approach 2:
The MXene-based contact lenses are designed as disposable medical devices that can be manufactured at low cost using scalable techniques. The contact lens material matrix with embedded MXene particles enables cost-effective production while ensuring hygiene and performance consistency across batches
3Reliability
If wavelength filtering is enhanced to treat CVD, then color perception improves, but protection from harmful radiation is insufficient
Solution Approach 1:
The MXene-based contact lens serves multiple functions simultaneously: it filters visible wavelengths to improve color vision and blocks ultraviolet radiation to protect the eye. This multi-functional design integrates CVD management with UV protection in a single device, eliminating the need for separate protective measures
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The MXene-based lenses effectively filter wavelengths relevant to color vision deficiencies, enhancing color perception and providing protection from harmful radiation, with a cost-effective and scalable solution that can be tailored for individual needs.
Implementation Method 1
MXenes' tunable, optical, electrochemical and electronic properties can depend not only on the MXene composition but also on flake size and atomic structure. These properties allow this family of 2D materials to be tailored to a broad range of applications.
Implementation Method 2
Additionally, due to MXenes' ability to absorb ultraviolet light, these materials can provide the added benefit of protection against potential harmful radiation.
