Archery Bow Sight Adjustment Mechanism for Pin Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional archery bow sights are difficult to tune accurately due to cumbersome adjustment mechanisms, particularly for individuals with large fingers or arthritic conditions, and require multiple tedious steps, leading to imprecision in aligning sight pins with the vertical axis.
Innovation Solution
A bow sight mechanism that includes a guide with a curvilinear and linear portion to maintain alignment of sight indicia with a vertical axis, allowing for simple and rapid adjustment of sight elements, using a rotatable adjustment screw to move the sight indicia along the axis while rotating the sight element, ensuring precise alignment and spacing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a threaded fastener mechanism is used to adjust sight pins in a linear slot, then the sight indicia can be positioned along the vertical axis, but the adjustment process becomes tedious and imprecise requiring multiple steps
Solution Approach 1:
The patent replaces the manual threaded fastener mechanism with a micrometer screw mechanism. The micrometer screw provides precise linear movement through rotational motion, eliminating the need for multiple manual adjustment steps. The micrometer's thimble and sleeve interface allows for fine, controlled movement of the sight pin along the vertical axis, achieving both precision and ease of operation.
Solution Approach 2:
The patent introduces dynamic adjustment capability through the micrometer mechanism, allowing the sight pin to be precisely positioned and locked at any point along the vertical axis. The micrometer enables continuous, controlled movement rather than discrete adjustments, providing smooth and predictable positioning behavior that improves both precision and operational ease.
2Volume of moving object
If the sight pin is made miniscule for compactness, then the device size is reduced, but it becomes difficult for individuals with large fingers or arthritic conditions to grasp and move the pin
Solution Approach 1:
The patent introduces the micrometer mechanism as an intermediary tool that the user operates with their fingers, while the micrometer itself performs the precise movement of the sight pin. The user interacts with the micrometer's larger, easier-to-grasp thimble and sleeve, while the micrometer's internal mechanism translates this input into precise, controlled movement of the small sight pin, eliminating the need for the user to directly manipulate the miniscule pin.
Solution Approach 2:
The patent separates the user interface (micrometer mechanism) from the adjusted component (sight pin). The micrometer mechanism serves as a separate, user-friendly interface that operates independently from the small sight pin, allowing users with larger fingers to control the positioning of the miniscule pin without directly grasping it.
3Adaptability or versatility
If multiple sight pins are positioned along a common vertical axis, then the bow sight can accommodate multiple shooting distances, but the adjustment mechanism becomes more complex
Solution Approach 1:
The patent designs the micrometer mechanism to serve multiple functions: it can adjust any of the multiple sight pins along the common vertical axis using the same adjustment procedure. The micrometer mechanism is universal and can be applied to each sight pin independently, eliminating the need for different adjustment mechanisms for each pin and reducing overall device complexity despite the multi-distance capability.

AI summary
A bow sight including a mechanism that moves a sight element, while maintaining the alignment of an associated sight indicia with a substantially linear axis, by way of a simple adjustment of the mechanism. The adjustment mechanism can include a substantially curvilinear portion and an optional substantially linear portion, and associated projections guided by the curvilinear and linear portions, that move the sight indicia along a substantially linear, vertical axis. The curvilinear and linear portions can be slots, and the projections can be guided by the slots to move the indicia along the axis. Where there are multiple sight elements, multiple, unique adjustment mechanisms maintain each associated sight indicia in alignment with the axis while providing adjustment of the spacing between sight indicia. A method for tuning the bow sight is also provided, including, moving the sight indicia along a substantially linear axis and simultaneously rotating the sight element about the sight indicia.
