Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical systems face issues with optical elements becoming off-center during adjustments, leading to variations in light beam characteristics and detection results due to tolerance deviations between the optical element and threaded structures.
Innovation Solution
A device for mounting optical elements that uses a frame with a non-rotatable mount and a rotatable adjusting nut, where the mount translates relative to the frame, preventing off-center issues and ensuring stable light beam characteristics by engaging a threaded portion with a screw, and includes features like V-shaped slots and locking devices for precise positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If thread structures are used to adjust optical elements, then the distance between optical elements can be changed, but the optical element center will deviate due to tolerance between the optical element center and thread center
Solution Approach 1:
The adjustment mechanism is segmented into two independent functions: the threaded structure provides linear translation for distance adjustment, while a separate V-shaped guide structure provides rotational constraint for centering accuracy. This segmentation allows each component to specialize in one function, eliminating the coupling between translation and rotation that causes centering deviation in conventional single-threaded systems.
Solution Approach 2:
The V-shaped guide structure acts as an intermediary between the threaded adjustment mechanism and the optical element. It mediates the motion by allowing linear translation while blocking rotational movement, thus converting the single-degree-of-freedom threaded motion into a constrained two-degree-of-freedom motion (translation only, rotation prevented) that maintains optical element centering accuracy.

This segmentation allows each component to specialize in one function, eliminating the coupling between translation and rotation that causes centering deviation in conventional single-threaded systems.
