Adjusting Hand Wheel Set Zero Position Limiting Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gun aiming systems lack a reliable method to consistently return to the zero position after correction, leading to misoperations and reduced accuracy due to the non-uniqueness of the zero position and difficulty in remembering or achieving the correct rotation.
Innovation Solution
An adjusting hand wheel set with a zero position limiting function, featuring a linkage ring, stop ring, and limit protrusions that align with a zero position mark on the lens barrel, ensuring precise return to zero by forming a mechanical limit when the hand wheel reaches the correct position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the adjusting hand wheel is rotated to return to zero position, then the shooting accuracy can be improved, but the user may rotate one more turn in wrong direction or forget the zero position, leading to misoperation
Solution Approach 1:
The patent introduces a feedback mechanism through the stop ring and limit protrusion that provides tactile and visual confirmation when the zero position is reached. The stop ring rotates with the adjusting hand wheel and its limit protrusion engages with the限位 groove on the lens barrel, creating a physical feedback signal that informs the user when zero position is achieved, eliminating the need to remember rotation amounts.
Solution Approach 2:
The stop ring serves as an intermediary component between the adjusting hand wheel and the lens barrel. It transfers the rotation motion and provides a mechanical interface through the limit protrusion and限位 groove that ensures accurate positioning without requiring the user to directly control the precise rotation angle.
2Device complexity
If the adjusting hand wheel set is designed without zero position limiting function, then the device complexity is reduced, but misoperations occur easily during the process of returning to zero
Solution Approach 1:
The patent segments the zeroing function into distinct components: the stop ring as a separate limiting mechanism, the limit protrusion as a positioning element, and the限位 groove as a constraint feature on the lens barrel. This segmentation allows each component to perform its specific function independently while working together to ensure accurate zero positioning.
Solution Approach 2:
The limit protrusion and限位 groove are pre-configured in specific positions before use. The stop ring is pre-positioned on the adjusting hand wheel, and the限位 groove is pre-machined on the lens barrel at the correct angular position. This preliminary configuration ensures that when the adjusting hand wheel is rotated, the zero position is automatically limited and confirmed without requiring complex real-time control.
3Adaptability or versatility
If multiple users share the same gun, then the gun can be used by different people, but each user may not know the specific zero position and may perform wrong rotation
Solution Approach 1:
The stop ring and limit protrusion mechanism enables the adjusting hand wheel to self-limit its rotation to the zero position regardless of who is operating it. Each user can independently return the hand wheel to zero by rotating until the stop ring engages with the限位 groove, without needing to know or remember the specific rotation amount or previous settings.
Solution Approach 2:
The patent uses visual indicators (such as markings or color codes on the stop ring or adjusting hand wheel) to indicate when the zero position is reached. This visual feedback allows any user to quickly identify the correct position without needing to understand the mechanical details or remember previous configurations.
