Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If separate curved mirrors are used for reflection imaging, then virtual image can be formed, but light loss occurs and assembly becomes complex
Solution Approach 1:
The patent merges the curved mirror function and refraction imaging function into a single integrated optical component. The inner surface of the optical apparatus serves as a curved mirror for reflection imaging, while the outer surface provides refraction imaging, eliminating the need for separate curved mirrors and reducing light loss at multiple interfaces.
Solution Approach 2:
The optical apparatus is designed with multi-functionality where the same component performs both reflection imaging (via the curved inner surface) and refraction imaging (via the outer surface). This universal design reduces the number of separate components needed while maintaining both imaging functions.
2Volume of moving object
If separate curved mirrors are used, then virtual image formation is achieved, but device size increases
Solution Approach 1:
By combining the curved mirror and refraction imaging functions into a single optical apparatus, the overall device volume is reduced. The integrated structure eliminates the need for separate curved mirrors and associated mounting mechanisms, leading to a more compact design.
3Reliability
If separate curved mirrors are used, then reflection imaging is possible, but image consistency between eyes deteriorates
Solution Approach 1:
The integrated optical apparatus ensures consistent image quality between eyes by using a single unified component for both reflection and refraction imaging. This eliminates the assembly variations and alignment issues that would occur with separate curved mirrors, providing more reliable and consistent visual output.
