Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If spherical optical lenses are directly connected to toric lenses, then the combination of different curvature profiles is achieved, but the curvature profiles are not parallel resulting in deterioration of image quality
Solution Approach 1:
The patent introduces an intermediate adapter component with a first bearing surface matching the spherical optical lens and a second bearing surface matching the toric lens. This intermediary element mediates between the two incompatible curvature profiles, allowing both lenses to be firmly connected while maintaining their respective curvature characteristics and preserving image quality.
Solution Approach 2:
The connection system is divided into three separate components: the spherical optical lens, the adapter with non-parallel bearing surfaces, and the toric lens. This segmentation allows each component to maintain its optimal curvature profile while the adapter handles the curvature transition, preventing direct contact between incompatible surfaces.
2Adaptability or versatility
If spherical optical lenses are directly connected to toric lenses, then the combination of different curvature profiles is achieved, but rapid fogging occurs due to non-uniform contact
Solution Approach 1:
The adapter serves as an intermediary that ensures uniform contact distribution between the spherical optical lens and the toric lens. By providing bearing surfaces with appropriate curvature profiles, the adapter prevents point-contact stress concentrations that would otherwise cause rapid fogging, thereby improving reliability while maintaining curvature profile compatibility.
3Adaptability or versatility
If spherical optical lenses are directly connected to toric lenses, then the combination of different curvature profiles is achieved, but high mechanical stress develops at connection points causing connection to tear
Solution Approach 1:
The adapter with non-parallel bearing surfaces acts as a stress-distributing intermediary between the spherical optical lens and the toric lens. It transforms concentrated point stresses into distributed contact stresses across the bearing surfaces, preventing mechanical failure and enhancing connection durability while accommodating different curvature profiles.
Solution Approach 2:
The adapter changes the geometric parameters of the connection interfaces by providing bearing surfaces with specific curvature profiles that match both the spherical and toric lenses. This parameter transformation allows for uniform stress distribution and prevents mechanical stress concentrations that would lead to connection failure.
4Adaptability or versatility
If viewing discs with different curvature profiles are combined, then the versatility of lens combination is improved, but the curvature profiles are not parallel resulting in connection problems
Solution Approach 1:
The adapter serves as a universal intermediary component that simplifies the connection structure between viewing discs with different curvature profiles. Rather than requiring complex custom-designed connections for each curvature combination, the adapter provides a standardized interface that accommodates various curvature profiles, thereby reducing overall device complexity while maintaining versatility.
