Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bow hunters face difficulties in quickly and accurately determining distances to targets from elevated positions, as existing bow sights require cumbersome processes and extra time, potentially spooking animals before a shot can be taken.
Innovation Solution
A fluid-filled tubular device mounted to a bow sight with an indicating mechanism that accounts for the operator's height, allowing for quick distance determination by correlating fluid levels with known distances, integrated with adjustable sight pins and a pin guard for protection and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a traditional bow sight with pins is used, then the shooter can determine distance by aligning with pins, but the process is cumbersome and time-consuming when at elevated positions
Solution Approach 1:
The patent replaces the mechanical pin-alignment system with a fluid-filled tube indicating mechanism. The fluid level in the tube naturally indicates the correct pin alignment for the current elevation angle, eliminating the need for the shooter to manually align pins or use external distance finding devices. This substitution of mechanical alignment with passive fluid indication dramatically reduces the time required to determine target distance.
Solution Approach 2:
The fluid-filled tube system is self-aligning and self-indicating. As the shooter changes elevation angle, the fluid automatically levels out to indicate the correct pin position without requiring active manipulation or external reference. The system serves itself by using the shooter's own elevation angle change to drive the indication mechanism, eliminating the need for separate measurement operations.
2Measurement precision
If the shooter uses a distance finder device, then accurate distance can be determined, but extra movement and time are required which may spook the animal
Solution Approach 1:
The patent merges the distance indication function directly into the bow sight assembly by integrating the fluid-filled tube with the pin alignment mechanism. This combination allows the shooter to determine both the correct elevation angle (via pin alignment) and the corresponding distance (via fluid level indication) simultaneously in a single operation, eliminating the need for separate distance finder devices and reducing overall operational complexity.
Solution Approach 2:
The fluid-filled tube acts as an intermediary between the shooter's elevation angle and the distance indication. Instead of requiring direct measurement or complex calculations, the fluid level in the tube serves as a visual mediator that translates the shooter's physical positioning into an intuitive distance reading, making the system easier to operate while maintaining accuracy.
3Adaptability or versatility
If the bow sight is designed for ground-level use, then it provides sufficient aid for known distances, but it cannot quickly determine distances when the bow hunter is at an elevated position
Solution Approach 1:
The patent introduces dynamic adaptability to the bow sight through the fluid-filled tube system. The fluid level continuously adjusts and re-indicates as the shooter changes elevation angle, allowing the same sight mechanism to accurately serve multiple distance ranges and shooting scenarios. This dynamic response enables the sight to adapt automatically to elevated positions without requiring manual reconfiguration or separate measurement operations.

AI summary
A distance indicating mechanism can be used in combination with a bow sight to quickly determine distances to targets from an elevated position. The distance indicating mechanism has a generally circular, fluid-filled tubular device with one or more adjustable indicators located thereon. The indicators are positionable to correspond with the fluid level in the tubular device to indicate the orientation of the mechanism when aiming at a known distance. Each indicator generally corresponds to a sight pin of a bow site that indicates a corresponding linear distance for which an arrow will be at a desired vertical position when shot by a bow operator.
