Tracking Device With Adjustable Rotation Shaft Angles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tracking devices for celestial bodies face challenges in omnidirectional observation due to blind spots caused by intersecting main and sub-rotation shafts, limiting their ability to adapt to different tracking methods and object characteristics.
Innovation Solution
A tracking device with a modular design that allows for switching between altitude-azimuth, equatorial, and altitude-altitude control methods by adjusting the installation angle of the main rotation shaft, using a first and second rotation unit and a posture change unit with adjustable fixtures and an auxiliary angle controller to prevent shaft intersection and enhance observational stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the main rotation shaft and sub-rotation shaft are positioned to enable omnidirectional observation, then observation coverage is improved, but the shafts may intersect and block the view
Solution Approach 1:
The patent positions the main rotation shaft and sub-rotation shaft at different vertical heights, transforming a two-dimensional planar arrangement into a three-dimensional spatial configuration. This dimensional change allows both shafts to coexist without intersecting, eliminating mutual obstruction while maintaining omnidirectional observation capability.
2Stability of the object's composition
If a fixed mounting structure is used, then structural stability is improved, but adaptability to different tracking methods is reduced
Solution Approach 1:
The patent employs an adjustable mounting structure that allows the main rotation shaft to be positioned at different angles and orientations. This dynamic configuration enables the system to adapt to various tracking methods (equatorial, altitude-azimuth, horizontal) while maintaining structural stability through secure fixation at each configured position.
Solution Approach 2:
The adjustable mounting structure serves multiple functions: it provides stable support for the rotation shaft, enables adaptation to different tracking methodologies, and allows reconfiguration for various observation scenarios. This multi-functionality resolves the contradiction between stability and adaptability.
3Speed
If the main rotation shaft rotates rapidly to cover large angular distances, then tracking speed is improved, but precision control becomes more difficult
Solution Approach 1:
The patent divides the tracking motion into two independent rotational segments: the main rotation shaft for rapid large-angle positioning and the sub-rotation shaft for fine-adjustment and precision control. This segmentation allows each axis to operate at its optimal speed and precision level, resolving the contradiction between fast tracking and precise control.
