Adjustable Projectile Launcher Sight for Long-Range Trajectory Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing projectile launchers, such as bows, face challenges in achieving accurate long-range aiming due to the curvature of the projectile's trajectory, which conventional sights cannot adequately account for, especially at varying distances.
Innovation Solution
A sight system with an adjustable housing and multiple sight pins, including a level and mirror, allows for precise alignment and adjustment to compensate for trajectory curvature by altering the line of departure and elevation based on target distance, featuring an open bottom design for arrow clearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional sights are used, then the structure is simple, but the accuracy at long range is insufficient due to inability to compensate for trajectory curvature
Solution Approach 1:
The sight system employs adjustable components including a movable sight pin and adjustable housing orientation that allow dynamic adaptation to different target distances. The housing can be rotated to different angular positions, and the sight pin can be repositioned, enabling the system to compensate for trajectory curvature at various ranges while maintaining a relatively simple overall structure.
Solution Approach 2:
The invention changes geometric parameters of the sight system by allowing the housing to be oriented at multiple angular positions and the sight pin to be positioned at different locations. These parameter adjustments enable the sight to account for trajectory curvature without requiring complex mechanical or optical systems, resolving the contradiction between accuracy and complexity.
2Strength
If the housing is fully enclosed, then the structural integrity is improved, but the arrow clearance is reduced
Solution Approach 1:
The housing design extracts or removes material from the bottom portion to create an open area. This extraction maintains the structural integrity of the housing through the remaining walls while providing sufficient clearance space for the arrow to pass through without interference, resolving the contradiction between enclosure and clearance.
Solution Approach 2:
The housing has different structural characteristics at different locations: the sides and top portions maintain full enclosure for structural strength, while the bottom portion has an open configuration to provide arrow clearance. This local differentiation allows simultaneous satisfaction of both structural integrity and clearance requirements.
3Adaptability or versatility
If the sight is fixed in position, then the manufacturing precision is improved, but the adaptability to different distances is reduced
Solution Approach 1:
The sight system incorporates adjustable components that allow the sight pin position and housing orientation to be dynamically changed according to the target distance. This dynamic adjustability provides versatility across different ranges while maintaining precise positioning capability through controlled adjustment mechanisms, resolving the contradiction between adaptability and manufacturing precision.
