Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing angle adjustment mechanisms for optical instruments are complex and occupy too much space, making them unsuitable for smaller volume devices.
Innovation Solution
A compact angle adjustment mechanism featuring a hollow cylindrical fine adjustment seat with tapered fine adjustment screws and a mounting seat having a tapered surface with strip-shaped planes, allowing precise control over the angle of emitted light by advancing or retreating the screws along the strip-shaped planes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional horizontal and vertical adjustment screws are used, then angle adjustment function is achieved, but device complexity and space occupation increase
Solution Approach 1:
The patent combines horizontal and vertical adjustment functions into a single integrated adjustment mechanism. The adjustment screw (20) with its specific thread structure integrates both adjustment directions, eliminating the need for separate horizontal and vertical screws. This merging reduces the number of components and simplifies the overall adjustment structure while maintaining full angle adjustment capability.
Solution Approach 2:
The adjustment mechanism is segmented into functional zones: the adjustment screw (20) with first and second threaded portions, the first adjustment component (10) with first threaded hole, and the second adjustment component (30) with second threaded hole. This segmentation allows independent control of different adjustment functions while using a unified actuation mechanism, reducing complexity.
2Ease of operation
If traditional adjustment screws are used, then angle adjustment is achieved, but space occupation increases
Solution Approach 1:
The adjustment mechanism employs a nested structure where the adjustment screw (20) is positioned within the housing (40), and the first and second adjustment components (10, 30) are nested within the housing structure. The first adjustment component (10) contains the first threaded hole, and the second adjustment component (30) contains the second threaded hole, creating a compact nested arrangement that minimizes the overall volume of the adjustment mechanism.
Solution Approach 2:
The patent utilizes three-dimensional spatial arrangement to compact the adjustment mechanism. The adjustment screw (20) extends in one dimension while the threaded portions engage with adjustment components arranged in perpendicular dimensions. This dimensional arrangement allows multiple adjustment functions to coexist in a compact space, reducing the overall volume occupied by the adjustment mechanism.

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 precise adjustment of the optical instrument's angle with reduced space requirements, suitable for smaller volume optical instruments, facilitating horizontal and vertical adjustments of the emitted light.
Implementation Method 1
The tapered fine adjustment screws can move forward or backward in a cavity formed by an inner wall of the fine adjustment seat and the tapered surface of the mounting seat along a strip-shaped plane that coincides with the respective tapered fine adjustment screw

AI summary
An angle adjusting mechanism of an optical instrument, comprising a hollow cylindrical fine adjustment seat (1). Conical fine adjustment screws (3) which are oppositely disposed and a mounting seat (2) having a conical surface (201) are provided in the hollow cavity of the fine adjustment seat (1) along the axial direction; four elongate planes (202) are evenly disposed on the conical surface (201) of the mounting seat (2) at intervals in the circumferential direction, wherein every two adjacent elongate planes (202) are in lap joint with conical surfaces of the two conical fine adjustment screws (3) in a matched mode; the conical fine adjustment screws (3) can move forward or backward in a cavity defined by the inner wall of the fine adjustment seat (1) and the conical surface of the mounting seat (2) along the elongate planes (202) matching the conical fine adjustment screws (3). The structure is particularly suitable for adjustment of the optical axis direction of an optical instrument having a small size, fine adjustment of the optical instrument in the horizontal direction and the vertical direction is achieved by pushing the conical fine adjustment screws (3), and thus adjustment of an angle of emergent light is achieved.
