Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the spacing distance between zoom units is adjusted to change the three-dimensional effect, then the stereoscopic image quality is improved, but the beam path length changes causing focusing errors
Solution Approach 1:
The third prism is positioned at a movable distance from the second prism to compensate for changes in beam path length. When the spacing between zoom units changes, the system automatically adjusts the position of the third prism to maintain constant optical path length, ensuring focusing accuracy is preserved while allowing three-dimensional effect adjustment.
Solution Approach 2:
The invention changes the physical parameter of beam path length by adjusting the distance between the second and third prisms. This parameter change compensates for the beam path length variations caused by zoom unit spacing adjustments, thereby maintaining focusing precision while enabling three-dimensional effect modification.
2Measurement precision
If the spacing distance between zoom units is fixed, then the focusing accuracy is maintained, but the three-dimensional effect cannot be adjusted according to user preference
Solution Approach 1:
The invention introduces dynamic adjustability to the optical system by making the distance between the second and third prisms variable. This dynamic parameter allows the system to adapt to different three-dimensional effect requirements while automatically maintaining focusing accuracy through compensatory movement of the third prism.
Solution Approach 2:
The third prism acts as an intermediary element that mediates between the zoom units and the final image formation. By adjusting its position, it compensates for beam path length changes and enables three-dimensional effect adjustment without compromising focusing accuracy.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables users to adjust the three-dimensional effect according to personal preference and ensures clear observation of objects with depth, such as holes, by maintaining beam path integrity during focusing adjustments.
Implementation Method 1
a pair of first prisms disposed on each of the zoom units, respectively, configured such that the pair of first prisms move in accordance with the pair of zoom units
Implementation Method 2
a pair of second prisms receiving a beam from the first prism to change a direction of the beam
Implementation Method 3
a third prism receiving the beam from the second prisms to change a direction of the beam, a spacing distance between the third prism and the second prism being adjusted by amount of changed beam path length

AI summary
A stereo microscope capable of not only adjusting the three dimensional effect of stereoscopic image but also focusing exactly even when the three dimensional effect of stereoscopic image is adjusted, is provided. A spacing distance of a pair of zoom unit can be adjusted so that a user can adjust three dimensional effect of image seen through an ocular lens according to personal tendency to improve convenience. Additionally, an object with a depth such as a hole can be exactly observed without interference of a boundary. Further, even though the three dimensional effect of an image is adjusted by adjusting the spacing distance of the pair of zoom units, the focus of optical system can be exactly adjusted.
