Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional reflex sights offer fixed aim point sizes, limiting user flexibility and requiring multiple purchases for different minute of angle (MOA) needs, which is cost-prohibitive.
Innovation Solution
A reflex sight design with an adjustable aim point size, utilizing a light source and control unit to vary the image size projected onto a lens without changing the shape or outer contour, allowing users to switch between different MOA settings through different lighting modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a small-sized dot (1 MOA) is used for precise aiming, then aiming precision is improved, but the dot becomes difficult for human eyes to find
Solution Approach 1:
The patent implements a dynamic aim point size adjustment system that allows the dot size to be changed between multiple MOA settings (e.g., 1 MOA, 3 MOA, 6 MOA, 9 MOA, 12 MOA) based on shooting distance and target conditions. This dynamic adjustment resolves the contradiction by enabling the user to switch between small dots for precision and large dots for visibility as needed.
Solution Approach 2:
The patent changes the parameter of dot size (MOA) to resolve the contradiction between precision and visibility. By providing multiple discrete size options and allowing continuous adjustment, the system enables optimal parameter selection for different shooting scenarios, thereby resolving the trade-off between small dot precision and large dot visibility.
2Difficulty of detecting and measuring
If a large-sized dot (6 MOA) is used for easy visibility, then the dot can be easily picked up by human eyes, but it cannot provide pin-point precision in aiming
Solution Approach 1:
The patent implements a dynamic aim point size adjustment system that allows the dot size to be changed between multiple MOA settings (e.g., 1 MOA, 3 MOA, 6 MOA, 9 MOA, 12 MOA) based on shooting distance and target conditions. This dynamic adjustment resolves the contradiction by enabling the user to switch between large dots for visibility and small dots for precision as needed.
Solution Approach 2:
The patent changes the parameter of dot size (MOA) to resolve the contradiction between visibility and precision. By providing multiple discrete size options and allowing continuous adjustment, the system enables optimal parameter selection for different shooting scenarios, thereby resolving the trade-off between large dot visibility and small dot precision.
3Adaptability or versatility
If multiple reflex sights with different aim point sizes are purchased to suit different needs, then flexibility in varying aim point size is achieved, but cost increases significantly
Solution Approach 1:
The patent creates a universal reflex sight that can perform multiple functions by adjusting the dot size to different MOA settings. Instead of requiring separate sights for different shooting scenarios, this single device provides all necessary dot sizes through electronic control, thereby reducing the quantity of equipment needed while maintaining full versatility.
Solution Approach 2:
The patent merges multiple aim point size options into a single reflex sight device. By integrating multiple LED elements that can be selectively activated to create different dot sizes, the system combines what would traditionally require multiple separate sights into one unified device, reducing both quantity and overall cost.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Provides cost-effective flexibility for users to adjust aim point size according to specific needs without needing multiple reflex sights, maintaining precision and accuracy across various usage scenarios.
Implementation Method 1
reflex sight, or reflector sights, are widely used in the defense industries, shooting sports, as well as personal defense to assist target aiming. In principle, a reflex sight is an optical sight that allows the user to look through a partially reflecting lens and see an illuminated projection of an aim point

AI summary
An apparatus implementable on a firearm includes a lens, a light source, and a control unit coupled to control the light source. The light source is configured to project an image of an aim point onto the lens. In operation, the control unit is configured to vary a size of the image projected onto the lens by the light source without changing a shape or an outer contour of the image.
