Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a fixed wide-angle stereoscopic imaging optical system is used, then the optical system structure is simplified, but the imaging range is limited and image quality is degraded when expanding the imaging range
Solution Approach 1:
The patent applies the dynamics principle by making the imaging lens interchangeable, allowing the optical system to adapt to different imaging requirements. Users can replace the imaging lens to change the imaging range from wide-angle to telephoto, thereby resolving the contradiction between simplified structure and limited adaptability.
2Adaptability or versatility
If a relay optical system with interchangeable back unit is used, then the imaging range can be changed, but the base length becomes too long for natural stereoscopic vision
Solution Approach 1:
The patent applies segmentation by dividing the optical system into separate functional modules: an interchangeable imaging lens and a fixed attachment optical system. This allows the base length to be controlled and kept at a natural width while still enabling change of imaging range through lens replacement, resolving the contradiction between adaptability and base length control.
3Device complexity
If existing stereoscopic optical systems are used, then the optical structure is determined, but the base length cannot be adjusted to match human eye width for natural stereoscopic vision
Solution Approach 1:
The patent applies universality by designing the attachment optical system to work with multiple types of interchangeable imaging lenses. The fixed attachment system maintains a natural base length while the interchangeable lenses provide universal adaptability for different imaging ranges, resolving the contradiction between simple configuration and base length adjustability.

AI summary
An attachment optical system, to which an imaging lens is attachable on an object side of the attachment optical system includes two bending optical systems arranged in parallel. Each of the two bending optical systems includes a first reflective member and a second reflective member. Each of the two bending optical systems includes, in order from the object side to an image side, a front unit and a rear unit, which are separated by a maximum air gap on an optical axis in each bending optical system. At least one of the first reflective member and the second reflective member is disposed between a surface having refractive power and disposed closest to an object in the rear unit and a surface having refractive power and disposed closest to an image plane in the rear unit of each bending optical system.
