Archery Scope Magnetic Light Pack Fluorescent Dot
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current optical sighting devices for archery scopes face challenges in providing sufficient visual contrast in low light conditions without obstructing the sight line, and existing solutions like spooled fiber optic cables or battery-powered LEDs are either expensive, cumbersome, or not compliant with competitive archery rules.
Innovation Solution
An optical sighting assembly with a magnetic scope body, detachable accessories, and a light pack that includes a battery-powered LED integrated into the scope housing, allowing for quick attachment and detachment, and a fluorescent aiming point that is visible without illumination, eliminating the need for optical fibers and providing obstruction-free sight lines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If spooled fiber optic cable is used to collect ambient light, then visual contrast in low light conditions is improved, but the up pin obstructs the sight line reducing aiming accuracy
Solution Approach 1:
The patent removes the obstructive up pin structure entirely and replaces it with a fluorescent dot applied directly to the lens surface. This extracts the harmful obstruction element while preserving the light-collecting function through the fluorescent material that glows when illuminated by ambient light or LED, maintaining visual contrast without blocking the sight line.
Solution Approach 2:
The patent employs fluorescent material that changes from a non-visible or low-visibility state to a high-visibility glowing state when illuminated. The fluorescent dot on the lens absorbs ambient light or LED illumination and re-emits it at a different wavelength (typically UV to visible), creating high contrast against the target background without requiring an opaque up pin structure.
2Illumination intensity
If battery powered LED is used to illuminate the aiming point, then visual contrast in very low light conditions is improved, but the battery pack and wires become cumbersome and may get tangled
Solution Approach 1:
The patent extracts and eliminates the cumbersome battery pack and wire assembly by using a compact LED that can be integrated directly into the scope housing or mounted on the lens holder. This removes the external power supply components that cause tangling and mechanical interference, while the LED provides sufficient illumination when activated.
Solution Approach 2:
The patent merges the LED light source with the scope housing structure or lens holder, integrating the illumination function into the existing scope components. This consolidation eliminates separate battery packs and wiring harnesses, reducing complexity and improving ease of operation while maintaining the ability to provide illumination when needed.
3Device complexity
If directly installed LED is used on scope housing, then wires and ad-hoc attachment solutions are eliminated, but the device becomes difficult to remove and modify
Solution Approach 1:
The patent segments the illumination system into a separate, removable LED component that can be independently attached to or removed from the scope housing. This modular approach allows the LED to be easily installed and removed without affecting the scope housing structure, maintaining both attachment simplicity and modifiability. The LED can be mounted on the lens holder or housing surface using simple mounting mechanisms.
4Strength
If threaded or screwed accessories are used for lens retainer, then secure attachment is achieved, but attaching and detaching takes time and rotational alignment cannot be ensured
Solution Approach 1:
The patent replaces the threaded mechanical fastening system with a friction-fit or snap-fit mechanism for the lens retainer. This substitution eliminates the need for screwing and unscrewing operations, reducing attachment and detachment time significantly. The new mechanism provides sufficient holding strength through friction and geometric interlocking while allowing quick release, and the symmetrical design ensures rotational alignment is not critical.

AI summary
An optical sighting assembly including an improved scope body and detachable accessories is presented. The accessories can be magnetically attachable to the scope body and can include a lens cartridge, a light pack, power pack and/or an alignment ring. The lens cartridge can be keyed to be installed at a predetermined rotational orientation, and the lens cartridge can hold a small diameter lens. Lenses can include a fluorescent aiming point that can fluoresce due to ambient light and/or when illuminated by an LED. The light pack can include the LED, a power source, and a control interface for adjusting light output. Alternatively, the LED can be integrated into the scope body, and a battery pack can include a power source and a control interface for the LED.
