Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional reticles with hatches are used for hold over compensation, then the device structure remains simple, but the aiming accuracy deteriorates because the hatches are not labeled and require manual determination
Solution Approach 1:
The patent replaces the mechanical/optical reticle system with an electronic display system. Instead of using physical hatches on a reticle that require manual interpretation, the system uses an electronic display (such as an LCD or LED display) to show digitally calculated hold over values. This substitution of mechanical elements with electronic components enables precise, labeled numerical displays of aiming corrections without the complexity of graduated reticle markings.
Solution Approach 2:
The patent introduces a computer or processing unit as an intermediary between the shooter and the target. This intermediary device receives inputs about environmental conditions (temperature, humidity, wind speed, wind direction, altitude) and bullet characteristics, then calculates the appropriate hold over compensation and presents it through the electronic display. This intermediary performs the complex calculations and presentations the results in a clear, labeled format that eliminates the need for manual reticle interpretation.
2Ease of operation
If manual determination of hold over using unlabeled hatches is required, then the device complexity remains low, but the ease of operation deteriorates as riflemen must understand and calculate the correct hatch usage
Solution Approach 1:
The system performs self-service by automatically calculating and displaying the hold over compensation without requiring the shooter to perform manual calculations or interpretations. The electronic display system takes environmental inputs and bullet data, then autonomously computes and presents the correct aiming adjustment. This self-service capability eliminates the need for the rifleman to understand complex reticle markings or perform ballistics calculations, significantly improving ease of operation.
Solution Approach 2:
The system performs preliminary calculations of hold over compensation based on pre-input environmental conditions and bullet characteristics. Before the shooter even aims, the computer has already processed the environmental data (temperature, humidity, wind, altitude) and bullet information to determine the appropriate compensation values. These pre-calculated values are then displayed on the electronic display, allowing the shooter to simply read and apply the corrections without any mental calculation or interpretation during the critical aiming moment.
3Measurement precision
If environmental factors and bullet characteristics are considered for accurate trajectory, then shot accuracy improves, but the ease of operation deteriorates as riflemen must adjust for multiple variables
Solution Approach 1:
The system is designed with multi-functionality to handle multiple environmental factors and bullet characteristics simultaneously. The computer or processing unit is configured to accept and process various inputs including temperature, humidity, wind speed, wind direction, altitude, and bullet properties (ballistic coefficient, muzzle velocity, weight). This universal system consolidates multiple adjustment functions into a single integrated device that automatically considers all these variables and computes the combined effect on bullet trajectory, eliminating the need for the shooter to manually adjust for each factor separately.
Solution Approach 2:
The computer acts as an intermediary that manages the complexity of multiple environmental variables and bullet characteristics. Instead of requiring the shooter to understand and adjust for each factor individually, the intermediary device receives all the relevant data inputs, performs the complex ballistics calculations considering all variables simultaneously, and presents a single integrated hold over compensation value. This intermediary absorbs the complexity of multiple variables while providing a simplified output that is easy to apply.

AI summary
A sighting system for visually acquiring a target includes an optic device having a transmissive LED array affixed thereon. The transmissive LED array includes two or more LED elements that are separately addressable to provide an aiming point. In embodiments, the sighting system receives information from an input system, such as ammunition information or environmental information, executes a ballistics program to determine ballistics information using the received information, and determines a range to the target. A controller calculates an aiming point using the ballistics information and the target range. The controller then addresses or energizes one of the LED elements to provide the aiming point.
