Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bowfishermen face challenges in accurately targeting underwater fish due to light diffraction and refraction, leading to frequent misses as they need to estimate the correct aim point without precise guidance.
Innovation Solution
A bowfishing system equipped with a laser sight that includes a 5 milliwatt green laser, a switch for activation, and an adjustable attachment device to securely attach the laser to the bow, allowing for precise alignment of the laser beam with the arrow's trajectory to compensate for light refraction and improve aiming accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If bowfishermen use unassisted sighting or instinctive shooting technique, then the equipment complexity is low, but the measurement precision of target location is poor
Solution Approach 1:
The patent introduces a laser sight as an intermediary device between the bowfisherman and the underwater target. The laser projects a visible beam through the water surface refraction zone, creating a reference indicator that shows the apparent target location. This intermediary visual aid allows the bowfisherman to accurately compensate for light refraction without requiring complex optical instruments or sophisticated sighting mechanisms.
2Measurement precision
If bowfishermen use pin sight to assist targeting, then the measurement precision improves slightly, but the device complexity increases and accuracy is still insufficient due to light diffraction
Solution Approach 1:
The patent replaces traditional mechanical pin sights with an optical laser-based sighting system. Instead of using mechanical alignment pins that require complex adjustment mechanisms, the system uses a laser to project a visual beam through the water. This substitution of mechanical sighting with optical illumination provides a more直观 (intuitive) and accurate reference for compensating for light refraction, achieving superior accuracy with simpler mechanics.
3Reliability
If bowfishermen estimate the correct aim point to compensate for light diffraction, then no additional equipment is needed, but the reliability of target acquisition is low due to frequent misses
Solution Approach 1:
The laser sight provides real-time visual feedback to the bowfisherman by projecting a beam that indicates the apparent location of the underwater target. This feedback mechanism allows the archer to see exactly where the laser beam appears to originate from underwater, enabling accurate compensation for light refraction. The visual feedback loop significantly improves target acquisition reliability by eliminating the guesswork involved in estimating aim points.
