Telescopic Tube Focusing Assembly With Angled Push Rod
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional telescopes are bulky and awkward to use due to their design, and the push rods are subjected to significant mechanical stress from long levers when focusing, making operation cumbersome.
Innovation Solution
The telescope design features a push rod with one end in a tube and another end in the articulated bridge, forming an acute angle with the joint axis, and includes a focusing knob accessible from both top and bottom, with ergonomically designed holding recesses and a Schmidt-Pechan prism system for compactness and reduced mechanical stress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the push rod is located far from the articulated bridge, then the focusing device can be positioned in a conventional manner, but the push rod is subjected to considerable mechanical stress due to long levers
Solution Approach 1:
The push rod is arranged at an angle of 45 degrees to the joint axis, changing the spatial orientation from the conventional parallel arrangement. This angular arrangement in a different dimensional configuration reduces the lever arm length, thereby minimizing mechanical stress on the push rod while maintaining focusing functionality
2Device complexity
If conventional telescope design is used, then the optical system is straightforward, but the telescope is bulky and awkward to use in the holding area
Solution Approach 1:
The focusing lens is integrated into the articulated bridge structure, with the push rod and focusing gear nested within the bridge assembly. This nesting arrangement eliminates the need for separate focusing mechanisms in the tube housing, reducing overall bulkiness while maintaining optical functionality
Solution Approach 2:
The joint axis and optical axes are arranged in specific angular relationships (45 degrees to the push rod, acute angles between planes), creating a compact three-dimensional configuration that reduces the telescope's footprint in the holding area while preserving the optical path
