Windage Mechanism With Segmented Macro And Micro Drives
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current windage mechanisms for sights, such as micro-drives and macro-drives, are inefficient for making either large or small, precise adjustments, as micro-drives are slow for larger adjustments and macro-drives lack precision for small adjustments.
Innovation Solution
A windage mechanism that combines a micro-knob with a worm gear and a boss system, allowing for both large and small adjustments through a rack-and-pinion mechanism, providing audible and tactile feedback for precise positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a micro-drive mechanism is used for windage adjustment, then small precise adjustments can be made, but large adjustments become slow and inefficient
Solution Approach 1:
The windage adjustment system is segmented into two independent mechanisms: a macro-drive for large adjustments and a micro-drive for precise adjustments. The macro-drive uses a clamp and bar system that allows rapid movement of the sight pin over large distances, while the micro-drive uses a threaded screw mechanism for fine-tuned precise adjustments. This segmentation resolves the contradiction by providing each mechanism with its optimal function range.
2Productivity
If a macro-drive mechanism is used for windage adjustment, then large adjustments can be made quickly, but small precise adjustments become difficult
Solution Approach 1:
The windage adjustment system is segmented into two independent mechanisms: a macro-drive for large adjustments and a micro-drive for precise adjustments. The macro-drive uses a clamp and bar system that allows rapid movement of the sight pin over large distances, while the micro-drive uses a threaded screw mechanism for fine-tuned precise adjustments. This segmentation resolves the contradiction by providing each mechanism with its optimal function range.
3Measurement precision
If a threaded screw micro-drive is used, then precise control is achieved, but the mechanism becomes complex and requires multiple turns for adjustment
Solution Approach 1:
The invention merges the macro-drive and micro-drive mechanisms into a single integrated windage adjustment system. The macro-drive provides the structural framework with its clamp and bar, while the micro-drive's threaded screw integrates with this framework to provide fine adjustment capability. This merging reduces overall system complexity compared to having two separate adjustment systems, while maintaining both rapid adjustment and precise control capabilities.
