Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a physical carrier plate positioning apparatus is used to adjust the light emitter position, then the shooter can compensate for targets at various distances and misalignment, but the device becomes complex, requires tight manufacturing tolerances, and is subject to wear and breakage
Solution Approach 1:
The patent replaces the mechanical carrier plate positioning system with an electronic control system that uses a microprocessor to selectively activate different LEDs in an array. This substitution eliminates mechanical moving parts, threaded adjusters, and physical carrier plates while achieving the same functional goal of positioning the aiming point for targets at various distances.
Solution Approach 2:
The patent divides the light emitter into multiple discrete LEDs arranged in an array pattern. Instead of moving a single light source physically, the system segments the emitter into multiple stationary points that can be selectively activated. This segmentation allows the aiming point to be electronically repositioned across different locations in the field of view without mechanical movement.
2Ease of operation
If a physical carrier plate positioning apparatus is used, then the shooter can adjust the position, but the system is subject to wear and breakage and can lose accuracy due to shocks
Solution Approach 1:
The patent replaces the mechanical carrier plate positioning system with an electronic control system that uses a microprocessor to selectively activate different LEDs in an array. This substitution eliminates mechanical moving parts, threaded adjusters, and physical carrier plates while achieving the same functional goal of positioning the aiming point for targets at various distances.
Solution Approach 2:
The patent transitions from a static mechanical positioning system to a dynamic electronic control system. The microprocessor can rapidly and precisely switch between different LED configurations based on input signals, providing adjustable positioning without mechanical movement. This dynamic electronic approach eliminates wear and shock sensitivity inherent in mechanical systems.
3Manufacturing precision
If a physical carrier plate is used for positioning, then the light position can be adjusted, but the adjustment mechanism exhibits non-linear travel, dead positioning clicks, and inconsistency in resolution per revolution
Solution Approach 1:
The patent replaces the mechanical carrier plate positioning system with an electronic control system that uses a microprocessor to selectively activate different LEDs in an array. This substitution eliminates mechanical moving parts, threaded adjusters, and physical carrier plates while achieving the same functional goal of positioning the aiming point for targets at various distances.
Solution Approach 2:
The patent transitions from one-dimensional mechanical adjustment (threaded adjusters rotating along a single axis) to a two-dimensional electronic control space. The microprocessor can independently control multiple LEDs arranged in rows and columns, allowing precise positioning in both horizontal and vertical dimensions through electronic switching rather than mechanical rotation.
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 accurate and reliable aiming without mechanical wear, eliminates the need for physical carrier plate adjustments, and enhances precision through programmable aiming patterns and bullet drop compensation.
Implementation Method 1
An LED or other light emitter is commonly used as the light source. When the emitter generates its light signal, the projected light reflects from the reflecting element
Implementation Method 2
the projected light reflects from the reflecting element, such as a lens or other optic, and the reflection is seen by the shooter as being superimposed on the target

AI summary
A reflex sight for a firearm includes an emitter array including a plurality of light emitters, each of the plurality of light emitters capable of being independently operated to produce light, a surface structured to reflect light from the emitter array to a user of the firearm, and a controller configured to receive input from the user and individually control the operation of the plurality of light emitters in the emitter array.
