Archery Scope Brightness Control via Rotatable Shield
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing archery scopes and sights do not allow archers to adjust the brightness of the sight pins, limiting user preference and accuracy in varying light conditions.
Innovation Solution
An archery scope with a housing containing a light receiving region and optical fibers arranged in a serpentine pattern, featuring a shield that can be rotated to control the amount of ambient light exposed to the fibers, allowing adjustable brightness of the sight pins.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the optical fiber is arranged in a serpentine pattern within the light receiving region, then the exposure of the optical fiber to ambient light is maximized, but the device complexity increases
Solution Approach 1:
The optical fiber is arranged in a serpentine (snake-like) pattern within the light receiving region, utilizing curved and winding paths to maximize the fiber's exposure to ambient light. This curved arrangement increases the effective light-capturing path length compared to a straight configuration, thereby enhancing illumination intensity without requiring additional light sources.
2Adaptability or versatility
If the shield is rotated to control the amount of light exposed to the optical fiber, then the brightness of the sight pin is adjustable, but the ease of operation decreases
Solution Approach 1:
The shield is designed to be rotatable relative to the housing, allowing dynamic adjustment of the amount of ambient light exposed to the optical fiber. This rotational mechanism enables the archer to adapt the brightness of the sight pin to various lighting conditions. The shield can be rotated to different angular positions to control light exposure, providing versatility in brightness adjustment.
3Adaptability or versatility
If the shield is made slidable to control light exposure, then the adaptability increases, but the device complexity increases
Solution Approach 1:
The shield is designed with a sliding mechanism that allows it to move relative to the housing along a defined path. This slidable configuration enables continuous adjustment of the light exposure area, providing fine-grained control over the brightness of the sight pin. The dynamic positioning capability allows the archer to adapt to varying lighting conditions by simply sliding the shield to the desired position.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables archers to customize the brightness of the sight pins, enhancing accuracy and usability in different lighting conditions by maximizing exposure to ambient light through a sliding shield mechanism.
Implementation Method 1
A fiber optic filament is wound a number of times around the sight to collect ambient light and supply it via the filament to an end portion thereof which is attached to a pin or crosshair of the sight

AI summary
An archery scope includes a housing having a light receiving region arranged on an exterior surface of a cylindrical sight portion and at least one sight pin connected with the housing and arranged within the sight portion. At least one optical fiber extends through the sight pin and through the light receiving region to receive ambient light and deliver it to the end of the sight pin. The optical fiber is arranged on the exterior surface in a serpentine pattern to maximize the length of the fiber exposed to ambient light. A shield is rotatably connected with the housing sight portion for movement between open and closed positions to increase and decrease the amount of ambient light directed to the optical fiber, respectively, so that an archer can control the brightness of the sight pin.
