Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If 3-D printing techniques are used to manufacture optical components, then manufacturing cost and productivity are improved, but the ability to generate aesthetically pleasing visual effects deteriorates
Solution Approach 1:
The patent employs core-shell filament structure where a transparent shell material surrounds a core material with different light transmissivity properties. This composite material approach enables the 3-D printed optical component to generate angularly-dependent light effects while maintaining cost-effective manufacturing. The shell portion (optically transparent) and core portion (different light transmissivity) work together to create the desired visual effects through their interaction with incident light.
Solution Approach 2:
The patent applies different material properties to different portions of the optical component - the shell portion is made optically transparent while the core portion has different light transmissivity. This local differentiation of material qualities enables the component to manipulate light in specific regions, creating angularly-dependent visual effects while maintaining overall manufacturing simplicity through the core-shell structure.
2Device complexity
If single-material optical components are used, then manufacturing simplicity is maintained, but the ability to create angularly-dependent light effects deteriorates
Solution Approach 1:
The patent uses a core-shell filament structure combining two different materials - an optically transparent shell material and a core material with different light transmissivity. This composite material structure enables the optical component to create angularly-dependent light effects by exploiting the different optical properties of the two materials, thereby increasing adaptability while maintaining reasonable manufacturing complexity.
Solution Approach 2:
The patent implements local quality differentiation by making the shell portion optically transparent while the core portion has different light transmissivity properties. This localized variation in material optical properties enables the component to interact with light differently at various locations and angles, creating versatile light effects.
