Bow Sight Integrating Visible and Infrared Lasers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bow sighting systems are inadequate for hunting in varying light conditions, as they require recalibration from day to night and often interfere with the archer's steadiness due to bulky night vision goggles, which hinder the use of pin settings and laser sights.
Innovation Solution
A bow sight system that integrates a visible laser, infrared laser, camera, and processor, allowing calibration during the day for use at night, with coordinated pin settings and automatic compensation for environmental factors, enabling seamless transition from daylight to dusk or night conditions without the need for recalibration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional bow sights use single light source (visible laser), then daytime targeting is accurate, but nighttime targeting fails due to lack of illumination
Solution Approach 1:
The bow sight integrates both visible laser (650nm) and infrared laser (808nm) sources into a single device, allowing it to function effectively in both daytime and nighttime conditions. The visible laser provides targeted illumination during daylight hours, while the infrared laser with integrated illuminator enables targeting in darkness, making the device universally applicable across all lighting conditions without requiring separate equipment.
2Illumination intensity
If night vision goggles are used for nighttime hunting, then nighttime target detection is improved, but the archer's steadiness deteriorates due to bulky equipment
Solution Approach 1:
The patent combines the infrared laser, infrared illuminator, and visible laser into a single integrated bow sight unit that mounts directly to the bow. This eliminates the need for separate night vision goggles and external illuminators, consolidating multiple functions into one compact device that does not interfere with the archer's steadiness or require additional bulky equipment.
Solution Approach 2:
The infrared illuminator acts as an intermediary device that provides active illumination for the infrared laser to reflect off the target and return to the sensor. This mediator enables nighttime targeting without requiring the archer to wear night vision goggles, as the system actively illuminates the target area rather than amplifying ambient light.
3Measurement precision
If visible laser is used for calibration during daytime, then daytime pin settings are accurate, but nighttime usage requires recalibration
Solution Approach 1:
The bow sight uses both visible and infrared lasers with identical optical paths and mounting geometry, ensuring that calibration performed during the day with the visible laser automatically applies to nighttime infrared operation. Since both lasers share the same mechanical mounting and optical alignment, a single calibration procedure validates the system for both daytime and nighttime use, eliminating the need for separate recalibration.
4Measurement precision
If conventional laser sights are used, then targeting accuracy is improved, but the system fails in dusk or nighttime conditions
Solution Approach 1:
The system integrates visible laser (650nm), infrared laser (808nm), and infrared illuminator capabilities into a single bow sight, enabling it to maintain high targeting accuracy across the full spectrum of environmental conditions from bright daylight through dusk to complete darkness. Each laser type addresses specific lighting conditions while sharing common calibration and mounting infrastructure.

AI summary
A multiple laser sight system for an archery bow or the like configured so that the multiple laser systems can be calibrated together and having features such that the user can use one laser system during the day and one laser system during the light. The laser sight is further configured to not interfere with the optional use of conventional sighting pins and the use of evening infrared systems, like the prior art use of night vision goggles.
