Magnetic Returning Mechanism for Sight Zeroing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional impact-point regulating mechanisms for sights require significant space for springs to achieve desired returning force, necessitating changes in the layout of surrounding mechanisms, which is inefficient and inflexible.
Innovation Solution
The use of magnets, specifically a first magnet on the regulating cover and a second magnet on the regulating bolt, allows for a compact returning mechanism that maintains engagement without the need for spatial adjustments when changing the magnetic force, enabling quick and stable zeroing of the sight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a spring is used as the returning mechanism, then the regulating cover can return to its original position, but the spring occupies significant space and requires changes in the layout of surrounding mechanisms
Solution Approach 1:
The patent replaces the conventional spring-based mechanical returning mechanism with a magnetic returning mechanism. Magnets are disposed on the regulating cover and regulating bolt, using magnetic attraction force to return the regulating cover to its original position after zeroing operation, thereby eliminating the need for a large space-consuming spring and allowing flexible layout of surrounding mechanisms
2Force
If the spring force is increased to achieve desired returning force, then the returning mechanism becomes more effective, but the spring occupies more space and necessitates changes in the layout of adjacent mechanisms
Solution Approach 1:
The patent substitutes the spring-based force generation system with a magnetic force generation system. By adjusting the strength and positioning of magnets on the regulating cover and regulating bolt, the desired returning force is achieved without the space constraints imposed by spring design, allowing the layout of adjacent mechanisms to remain unchanged
3Force
If the layout of mechanisms near the spring is changed to accommodate larger spring, then the spring can provide sufficient returning force, but the overall device complexity increases and adjacent mechanisms must be redesigned
Solution Approach 1:
The patent replaces the spring-based system with a magnetic system that does not require changes to the layout of adjacent mechanisms. The magnets are integrated directly onto the regulating cover and regulating bolt, providing the necessary returning force without forcing redesign of surrounding components, thereby maintaining device simplicity and reducing overall complexity

Function Achieved in This Case
This solution provides a more space-efficient and flexible mechanism for zeroing the sight, allowing for smooth and reliable engagement without altering the design of adjacent components, enhancing the overall performance and usability of the impact-point regulating mechanism.
Implementation Method 1
a first magnet disposed on the regulating cover, and a second magnet disposed on the regulating bolt and corresponding to the first magnet... The regulating cover is maintained in the second position through attraction of the first magnet and the second magnet

AI summary
The sight includes a main body, a regulating bolt movably joined to the main body, a securing bolt fixed to the regulating bolt, a regulating cover covering the regulating bolt and movable between a first position and a second position with respect to the regulating bolt, a first magnet disposed on the regulating cover, and a second magnet disposed on the regulating bolt and corresponding to the first magnet. The regulating cover is movable with respect to the regulating bolt when the regulating cover moves away from the second position. The regulating cover abuts the securing bolt and is rotatable with respect to the regulating bolt when the regulating cover moves to the first position. The regulating cover engages the regulating bolt when the regulating cover moves to the second position. The regulating cover is maintained in the second position through attraction of the first magnet and the second magnet.
