Telescope Focus Cover Segmentation for Simplified Focusing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional telescopes have a dust cover that only provides dustproof and protective functions, and the focus process is complicated, requiring removal of the dust cover and multiple steps.
Innovation Solution
A detachable focus cover with a tubular carrier, focus sheet, and covering body that simplifies the focus process by allowing the focus sheet to be positioned between the carrier and covering body, which are detachably fastened to the light-shielding tube, enabling precise focusing without altering the conventional cover's contour.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional one-piece dust cover is used, then the structure is simple and manufacturing is easy, but the focus process becomes complicated requiring removal of the cover and multiple steps
Solution Approach 1:
The cover is divided into multiple detachable segments: a dust cover portion for protection and a focus cover portion for focusing operations. This segmentation allows the focus cover to be detached during focusing and reattached afterward, simplifying the focus process while maintaining structural organization.
Solution Approach 2:
The focus cover structure serves multiple functions: it acts as a dust cover when attached, and as a focusing mechanism when detached. The connecting portion enables both protective and operational functions through a single integrated design, reducing the need for separate components.
2Ease of operation
If the dust cover is removed for focusing, then the focus process can proceed, but the telescope is exposed to dust and environmental factors
Solution Approach 1:
The focus cover is pre-positioned in a closed state that protects the telescope from dust. When focusing is needed, only the focus cover portion is detached rather than the entire cover, maintaining protection while enabling access. After focusing, the cover is reattached to restore protection.
Solution Approach 2:
The connecting portion acts as an intermediary mechanism that selectively connects or disconnects the focus cover from the telescope body. This mediator enables controlled access for focusing while maintaining the protective barrier against dust and environmental factors.
3Productivity
If a detachable focus cover is implemented, then the focus process is simplified, but the assembly and disassembly operations become more complex
Solution Approach 1:
The focus cover portion is nested within or integrated with the dust cover structure, allowing one component to be housed within another. This nesting arrangement enables the focus cover to be detached and reattached without requiring complete disassembly of the cover system, simplifying the operational complexity.
Solution Approach 2:
The dust cover and focus cover functions are merged into a single integrated cover assembly with a unified connecting portion. This combination reduces the number of separate components and simplifies the assembly structure while maintaining the ability to detach for focusing operations.

AI summary
A telescope includes a monocular assembly, an optical lens assembly, and a focus cover. The monocular assembly includes a monocular and a light-shielding tube movably sleeved at the monocular. The optical lens assembly is disposed in the light-shielding tube and is fixed on the monocular. The focus cover is detachably disposed on an end portion of the light-shielding tube and includes a tubular carrier, a focus sheet, and a covering body. The tubular carrier has a carrying portion formed on an inner side thereof, and includes a connecting portion and an accommodating portion respectively arranged at two opposite sides of the carrying portion. The connecting portion is detachably fastened to the end portion. The focus sheet is detachably positioned at the carrying portion and is arranged in the accommodating portion. The covering body is detachably fastened to the accommodating portion for shielding the focus sheet.
