Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current focusing devices for telescopes face challenges such as the inability to easily switch between automatic and manual focusing modes, the inconvenience of disconnecting electric focusers for manual focusing, and the lack of wireless control, which limits user comfort and safety during astrophotography.
Innovation Solution
A focusing apparatus and method that allows easy switching between automatic and manual focusing modes by using a rear sleeve that rotates between two positions to mesh or separate gears, enabling electric or manual focusing. The apparatus also includes a wireless Bluetooth function for remote control and an elastic damping member for improved focusing precision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the electric focusing apparatus is mounted on the telescope, then automatic focusing is achieved, but the manual focusing function is lost and the structure becomes more complex
Solution Approach 1:
The patent implements a dynamic switching mechanism where the electric focusing apparatus can be selectively connected or disconnected from the telescope's focusing mechanism. A switching component allows the user to dynamically change between electric and manual focusing modes by moving between engaged and disengaged positions, thereby resolving the contradiction between automation and manual operation flexibility.
Solution Approach 2:
The focusing system is segmented into independent electric and manual focusing pathways. The electric focusing apparatus operates independently when engaged, while the manual focusing mechanism remains available but inactive when the electric system is disengaged. This segmentation allows both functions to coexist without interference, enabling users to switch between modes as needed.
2Extent of automation
If the electric focusing apparatus is permanently connected, then automatic focusing is maintained, but the apparatus cannot be disconnected for manual focusing or storage
Solution Approach 1:
The connection between the electric focusing apparatus and the telescope is made dynamic rather than fixed. The switching component enables the electric focusing apparatus to be connected during automatic focusing operations and disconnected when manual focusing is needed or for storage purposes, providing adaptability to different operational requirements.
Solution Approach 2:
The switching component is pre-configured with specific positions (engaged and disengaged) that allow users to prepare the system in advance for different modes of operation. This preliminary positioning enables smooth transitions between electric and manual focusing modes without requiring complex disassembly or reassembly procedures.
3Adaptability or versatility
If the manual focusing knob is used with electric focusing mounted, then focusing can be performed without electricity, but the electric focusing may be damaged by forced manual rotation
Solution Approach 1:
The focusing mechanism is divided into separate manual and electric pathways with a switching component that isolates them. When in manual mode, the electric focusing apparatus is disconnected and cannot be damaged by manual rotation. When in electric mode, the manual pathway is isolated, preventing accidental damage to the electric components while allowing electric focusing to operate normally.
Solution Approach 2:
The switching component acts as an intermediary between the manual focusing knob and the electric focusing apparatus. It allows manual operation to proceed independently when needed while preventing direct mechanical connection that could damage the electric focusing system. The intermediary isolates the two systems, enabling safe operation in either mode.
4Ease of operation
If the focusing structure is made symmetrical with manual focusing on both sides, then manual focusing is available, but the structure becomes more complex and larger
Solution Approach 1:
The manual focusing mechanism is designed with multi-functionality, serving both as a standalone manual focusing system and as a complementary system that works with the electric focusing apparatus when disconnected. This universal design allows the same mechanical structure to fulfill multiple roles without requiring separate dedicated components for each function, thereby reducing overall structural complexity.

AI summary
A focusing apparatus for telescope focusing includes a to-be-focused member, an on-off limiting member and a drive fixation apparatus, where the to-be-focused member includes a first gear for focusing, the drive fixation apparatus includes a rear sleeve, a drive structure and a second gear, the rear sleeve is connected with the on-off limiting member through a limiting assembly, the drive structure is connected with the second gear, the second gear and the first gear are eccentrically arranged, and under a limiting action of the limiting assembly, the rear sleeve rotates, in relative to the on-off limiting member, between a first position and a second position on the on-off limiting member, to drive the second gear to mesh with and separate from the first gear in respective, thus the to-be-focused member is switched for electric focusing and manual focusing. The focusing apparatus is additionally provided with an on-off structure.
