Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing blue light blocking compounds are used in ophthalmic devices, then blue light blocking function is provided, but reactivity and miscibility with ophthalmic device material are poor
Solution Approach 1:
The patent modifies the chemical structure of blue light blocking compounds by introducing specific functional groups (carboxyl, hydroxyl, amino groups) and adjusting molecular weight parameters. These parameter changes improve both the reactivity with ophthalmic device materials and the miscibility within the material matrix, while maintaining the blue light blocking function through preserved chromophore structures.
Solution Approach 2:
The invention creates composite material systems by combining blue light blocking compounds with ophthalmic device materials through chemical reactions enabled by functional groups. The compound integrates into the ophthalmic device material matrix as a composite structure, improving compatibility and performance rather than remaining as a separate additive.
2Reliability
If blue light blocking compound is incorporated into ophthalmic device material, then blue light blocking function is achieved, but dispersion and reaction performance are insufficient
Solution Approach 1:
The patent optimizes molecular weight parameters of the blue light blocking compound to balance dispersion capability and reaction performance. By controlling molecular weight within specific ranges and introducing appropriate functional groups, the compound achieves optimal dispersion uniformity and reaction efficiency within the ophthalmic device material during manufacturing.
Solution Approach 2:
The functional groups (carboxyl, hydroxyl, amino) act as intermediaries that facilitate interaction between the blue light blocking compound and the ophthalmic device material. These intermediary groups enable chemical bonding and improve interfacial compatibility, enhancing both dispersion uniformity and reaction performance without compromising the primary blue light blocking function.
