Bow Sight Eye Alignment Assembly Using Optical Fiber Indicia
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mechanisms for aligning a user's body with tools, such as bows or golf clubs, are crude and inaccurate, leading to inconsistent performance due to the difficulty in converging the user's line of sight with the tool's operating axis, affecting accuracy and repeatability in operations like archery and golfing.
Innovation Solution
A bow sight with an eye alignment assembly featuring optical fibers and a lens with alignment indicia, allowing users to align their body with the tool in multiple degrees of freedom without directly aligning their line of sight with the tool's operating axis, using adjustable mechanisms for precise orientation indication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the user attempts to align their line of sight with the tool's operating axis, then measurement precision of body orientation is improved, but device complexity and ease of operation deteriorate due to the difficulty of converging line of sight with operating axis
Solution Approach 1:
The patent introduces an intermediary optical assembly with alignment indicia that mediates between the user's line of sight and the tool's operating axis. Instead of directly aligning line of sight with the operating axis, the user aligns their line of sight with the alignment indicia, which indirectly indicates alignment with the operating axis. This intermediary system simplifies the alignment operation while maintaining measurement precision.
Solution Approach 2:
The alignment system is segmented into distinct components: the optical assembly with alignment indicia, the sight pin, and the reference markings. This segmentation allows the alignment function to be separated from the operating axis, enabling independent optimization of each component and simplifying the overall alignment operation.
2Measurement precision
If an eye alignment apparatus is introduced to improve body positioning accuracy, then measurement precision of eye position is improved, but device complexity increases
Solution Approach 1:
The optical assembly serves multiple functions: it provides alignment indicia for eye positioning, acts as a reference frame for body orientation, and integrates with the existing sight pin structure. By making the alignment assembly multi-functional, the patent reduces the need for separate components, thereby limiting the increase in device complexity while maintaining measurement precision.
Solution Approach 2:
The patent merges the eye alignment function with the existing sight structure by integrating the optical assembly with the sight pin. This combination allows the alignment indicia to be presented within the existing operational context, reducing the need for additional separate alignment devices and limiting overall device complexity.

Function Achieved in This Case
The solution provides a precise indication of the user's body orientation relative to the tool, enabling consistent and accurate operation by decoupling the line of sight from the tool's axis, and optional phosphorescent fibers enhance usability in low light conditions.
Implementation Method 1
The optical fiber is exposed to gather ambient light and to transmit light to a sight point located within the frame assembly

AI summary
A bow sight with at least one sight pin mounted to a frame assembly. At least one optical fiber is attached to the sight pin. The optical fiber is exposed to gather ambient light and to transmit light to a sight point located within the frame assembly. The eye alignment assembly includes an optical structure mounted to the frame assembly including a sight point of an optical fiber located near a proximal end of the optical structure and a lens with alignment indicia located at a distal end of the optical structure. An adjustment system permits the optical structure to be reoriented relative to the frame assembly. The eye alignment assembly provides an indication of orientation of the shooter relative to the bow in at least two degrees of freedom.
