Sighting System With Digitized Feedback And Variable Adjustment Fineness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sighting systems have a fixed fineness of adjustment in their compensating mechanisms, making it inconvenient for users to correct bullet impact points for both near and far targets, as the fixed click increments are either too small or too large, and redesigning the mechanism to change this is complex and costly.
Innovation Solution
A sighting system with a compensating mechanism that includes a base, an adjusting unit, and a converting unit, which provides digitized feedback through a processing and output unit, allowing users to change the fineness of adjustment and input target values for precise and rapid correction of bullet impact points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the ring gear is designed to have more teeth to increase adjustment fineness, then the adjustment precision is improved, but the manufacturing complexity and cost increase
Solution Approach 1:
The patent applies dynamics by making the transmission ratio variable rather than fixed. The switching mechanism allows the system to dynamically change between different transmission ratios (first ratio for fine adjustment, second ratio for coarse adjustment), enabling the compensating mechanism to adapt its fineness of adjustment based on operational needs without requiring a ring gear with an excessive number of teeth for all scenarios
Solution Approach 2:
The patent segments the adjustment process into two distinct modes: fine adjustment mode and coarse adjustment mode. This is achieved by dividing the transmission path into different gear engagement configurations, where the first gear engages with teeth having a first pitch for fine adjustment, and the second gear engages with teeth having a second pitch for coarse adjustment, allowing each segment to be optimized independently
2Ease of manufacture
If the fineness of adjustment is fixed, then the manufacturing cost is reduced, but the adaptability to different target distances is worsened
Solution Approach 1:
The patent makes the adjustment fineness dynamic by incorporating a switching mechanism that allows users to change between different transmission ratios based on target distance. For near targets, the system can switch to a higher transmission ratio for finer control, while for far targets, it can use a lower transmission ratio for coarser adjustments, thereby maintaining versatility without increasing manufacturing complexity
Solution Approach 2:
The patent implements multi-functionality by designing a single compensating mechanism that can perform both fine adjustment and coarse adjustment functions. The switching mechanism enables the same base structure to operate in different modes, making the device universal for various shooting scenarios (different target distances) without requiring multiple specialized mechanisms
3Adaptability or versatility
If the ring gear is redesigned to change fineness of adjustment, then the adaptability is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent achieves changeable fineness of adjustment through a dynamic switching mechanism rather than redesigning the entire ring gear. The switching mechanism selectively engages different gears with the worm gear, allowing the system to change its transmission ratio and thus its adjustment fineness, while maintaining the same fundamental ring gear structure
Solution Approach 2:
The patent introduces a switching mechanism as an intermediary component that mediates between the worm gear and the different output gears. This intermediary allows the system to transition between different adjustment fineness levels without requiring direct redesign of the core ring gear, thereby adding minimal complexity while achieving the desired adaptability
