Configurable BDC Reticle for Dynamic Ammunition Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ballistic drop compensation (BDC) reticles in optical aiming devices have static patterns that do not accurately represent ranges for specific weapon and ammunition pairings, requiring calibration and experience to predict bullet drop, and are not easily adaptable to changes in gun or ammunition.
Innovation Solution
A configurable BDC reticle system that uses a processor and display device to project customizable BDC patterns based on user-selected ranges and ballistic trajectory data for specific weapon and ammunition pairings, allowing for dynamic adjustment and multiple pattern configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a static BDC reticle pattern is used, then the device structure is simple, but the reticle cannot accurately represent ranges for specific weapon and ammunition pairings
Solution Approach 1:
The patent applies the dynamics principle by making the reticle pattern configurable and adjustable based on specific weapon and ammunition pairings. Instead of a fixed static pattern, the reticle can be dynamically adjusted to match different ballistic trajectories, allowing accurate range indications for various gun and cartridge combinations while maintaining a relatively simple overall device structure.
Solution Approach 2:
The patent implements parameter changes by allowing modification of reticle pattern parameters such as holdover mark positions and spacing based on ballistic data for different weapon-ammunition pairings. This enables the reticle to accurately represent ranges for specific combinations by changing its display parameters without fundamentally altering the device structure.
2Measurement precision
If a custom BDC reticle is designed for a specific weapon and ammunition pairing, then the range indication accuracy is improved, but the adaptability to different pairings is reduced
Solution Approach 1:
The patent applies the universality principle by creating a configurable reticle system that can serve multiple weapon and ammunition pairings. The reticle can be adjusted and reconfigured to work with different gun and cartridge combinations, making a single reticle design universally applicable to various pairings rather than requiring separate custom reticles for each combination.
Solution Approach 2:
The patent makes the reticle dynamic and adaptable by allowing users to configure and adjust the reticle pattern based on the specific weapon and ammunition pairing being used. This dynamic configurability enables the same reticle to accurately serve multiple different pairings by changing its display characteristics to match the ballistic properties of each specific combination.
3Measurement precision
If the gun or ammunition changes, then the ballistic trajectory changes, but the static BDC pattern requires reticle replacement to maintain accuracy
Solution Approach 1:
The patent applies the dynamics principle by making the reticle pattern adjustable and reconfigurable when gun or ammunition changes occur. Instead of requiring physical reticle replacement, the system allows dynamic adjustment of the reticle display to match the new ballistic trajectory, maintaining accuracy while simplifying the adaptation process.
Solution Approach 2:
The patent implements parameter changes by allowing modification of reticle display parameters such as holdover mark positions and spacing based on the new weapon or ammunition pairing. This enables quick adaptation to changes in ballistic characteristics by changing the reticle's display parameters rather than replacing the entire reticle component.

AI summary
A system, method, and device for configuring an optical aiming device for ballistic drop compensation (BDC). The optical aiming device can include a housing with a reticle pane defining a reticle display field viewable by a user and indicating a zero point, the housing further including a plurality of axially spaced lenses and defining an optical path therethrough. In various embodiments the system includes a display device configured to project an image generated from a display, a processor, and a non-transitory computer readable storage medium. The computer readable data storage medium can include instructions executable by the processor to receive a first set of ballistics input data indicating a first type of ammunition, determine a BDC pattern including at least two holdover marks corresponding to at least two ranges for the first type of ammunition, and project the BDC pattern onto the reticle display field.
