Multi-Color Hunting Spotlight Rotational LED Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current night hunting spotlights are bulky, reduce light output with color filters, and are not easily mountable on firearms, requiring inconvenient LED changes and adjustments for different animal targeting, especially since they often lack multiple color options and maintain beam focus.
Innovation Solution
A multi-color spotlight with a rotatable mechanism allowing quick selection between LED colors without altering the beam's focal point, featuring LED chips in the same vertical plane on a rotatable rod, enabling easy firearm mounting and intensity control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single white LED is used in handheld flashlights, then the device is simple and compact, but the user cannot target different animals with different colors without carrying multiple lights
Solution Approach 1:
The patent combines multiple LEDs of different colors (red, green, blue, yellow, orange, purple) into a single flashlight housing, allowing the user to select different colors without carrying multiple separate lights. This merging of multiple light sources into one device directly resolves the contradiction by providing color versatility while maintaining a single compact unit.
Solution Approach 2:
The flashlight is designed to perform multiple functions by incorporating LEDs that emit different colors, each suitable for targeting different types of animals. The single device can switch between red light for deer, green light for hogs, and other colors as needed, making it a universal tool for various hunting scenarios rather than requiring specialized single-color lights.
2Adaptability or versatility
If multiple LEDs are placed on the circuit board, then color options are provided, but the beam position changes with each LED activation requiring manual adjustment
Solution Approach 1:
The patent positions all LEDs asymmetrically at the same focal point relative to the lens, rather than distributing them uniformly across the circuit board. This asymmetric placement ensures that regardless of which LED is activated, the light beam emerges from the same centered position, eliminating the need for manual windage or elevation adjustments when switching colors.
Solution Approach 2:
The patent creates a standardized LED mounting configuration where each LED is positioned to replicate the same optical path and focal point. This copying of the focal position across different colored LEDs ensures consistent beam alignment, allowing the user to switch colors without needing to re-align the sight picture.
3Ease of manufacture
If traditional spotlight designs with vertical handle grips and white bulbs are used, then the structure is simple, but the devices are bulky and not easily mountable on firearms
Solution Approach 1:
The patent transitions from a static, fixed-handle design to a dynamic, adaptable mounting system. The flashlight incorporates a Picatinny rail mount that allows it to be quickly attached to and removed from firearms, as well as a wrist strap for handheld use. This dynamic adaptability enables the same simple structure to serve multiple purposes and mounting configurations.
Solution Approach 2:
The patent separates the handle grip from the mounting interface, allowing the flashlight to be configured for different usage modes. The modular design includes a removable battery compartment and interchangeable mounting options, enabling the same basic structure to function as both a handheld light and a firearm-mounted light without requiring complex integrated designs.
4Adaptability or versatility
If plastic colored filters are placed over white light, then color options are achieved, but light output is reduced by up to 70 percent
Solution Approach 1:
The patent extracts the color-filtering function from a separate plastic filter component and integrates it directly into the LED light source itself. By using LEDs that naturally emit different colors rather than filtering white light, the design eliminates the 70% light loss associated with plastic filters while maintaining full color versatility.
Solution Approach 2:
The patent changes the fundamental parameter of light generation from filtering white light to direct colored LED emission. This parameter change from a subtractive process (filtering) to an additive process (direct emission) preserves maximum light output while achieving the same color selection capability, directly resolving the contradiction between color options and illumination intensity.
