Bow Sight Eye Alignment Assembly with Phosphorescent Fiber
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, especially in low light conditions.
Innovation Solution
A bow sight and eye alignment assembly using phosphorescent optical fibers as sight points, which provide an indication of orientation in multiple degrees of freedom, allowing the user to position their body correctly relative to the tool without aligning their line of sight with the tool's operating axis, and can be adjusted for individual shooting styles or techniques.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional alignment mechanisms are used, then the device structure is simple, but the alignment precision and measurement accuracy are insufficient
Solution Approach 1:
The alignment system is divided into separate functional modules: phosphorescent optical fibers for light transmission, alignment indicia for visual reference, and degree of freedom indicators for measurement. This segmentation allows each component to be optimized independently while maintaining overall system precision without excessive complexity.
Solution Approach 2:
Phosphorescent optical fibers serve as intermediaries between ambient light sources and the alignment indicia. These fibers transmit and concentrate light to create bright, visible alignment markers that improve measurement precision without requiring complex illumination systems or power sources.
2Illumination intensity
If phosphorescent optical fibers are used for sight points, then visibility in low light conditions is improved, but the device complexity increases
Solution Approach 1:
The phosphorescent optical fibers are self-illuminating through phosphorescence, absorbing and re-emitting ambient light without requiring external power sources, batteries, or complex illumination systems. This self-service mechanism provides consistent visibility across varying light conditions while maintaining simple device architecture.
Solution Approach 2:
The phosphorescent material exhibits light emission properties that enhance visibility of the sight points. The optical fibers convert absorbed light into visible phosphorescent emission, creating high-contrast alignment markers that remain visible in low light conditions without adding device complexity.
3Adaptability or versatility
If the eye alignment assembly is made adjustable for individual shooting styles, then the adaptability improves, but the ease of operation decreases
Solution Approach 1:
The eye alignment assembly incorporates adjustable components that can be dynamically repositioned to accommodate different shooting styles and user preferences. The adjustable sight points and alignment indicia allow customization while maintaining operational simplicity through intuitive adjustment mechanisms.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system enables precise alignment of the user's body with the tool, improving accuracy and consistency in tool operation by decoupling the line of sight from the operating axis, and functions effectively in both bright and low light conditions.
Implementation Method 1
At least a portion of the phosphorescent optical fiber is exposed to ambient light that is transmitted to a sight point on the sight pin
