Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If reflex sights are used for accurate shooting with flat-trajectory ammunition, then shooting precision is improved, but they become unsuitable for elevated-trajectory ammunition like grenades due to limited field of view and lack of ballistic correction capability
Solution Approach 1:
The sighting device is designed to handle both flat-trajectory and elevated-trajectory ammunition through electronic ballistic correction. The system includes a ballistic correction unit that calculates and adjusts the aiming point based on ammunition type, distance, and trajectory characteristics, allowing a single device to serve multiple functions that previously required different sighting systems.
Solution Approach 2:
The sight dynamically changes the displayed aiming point position based on ballistic parameters such as distance, ammunition type, and trajectory angle. The electronic display adjusts the virtual aiming point coordinates in real-time, allowing the same optical hardware to accurately aim for both flat and elevated trajectories through parameter modification rather than mechanical reconfiguration.
2Adaptability or versatility
If the field of view is increased to accommodate elevated trajectory aiming, then adaptability for different ammunition is improved, but the device size and complexity increase
Solution Approach 1:
The patent replaces complex mechanical adjustment mechanisms with an electronic display system. Instead of physically rotating or tilting the sight to change the field of view and aiming angle, the system uses a micro-display to present multiple aiming points and ballistic information electronically, eliminating the need for mechanical moving parts while maintaining full adaptability.
Solution Approach 2:
The invention transitions from a two-dimensional optical view to a multi-dimensional information display. The micro-display presents aiming points, ballistic trajectories, and correction data in multiple virtual dimensions, allowing the shooter to access elevated trajectory information without physically expanding the optical field of view or adding mechanical complexity.
3Measurement precision
If mechanical adjustment mechanisms are added to achieve ballistic correction, then accuracy for elevated trajectory is improved, but device simplicity and cost-effectiveness deteriorate
Solution Approach 1:
The patent replaces all mechanical adjustment mechanisms with an electronic ballistic correction system. A processor calculates the required aiming point adjustment based on input parameters (distance, ammunition type, environmental conditions), and a micro-display presents the corrected aiming point visually. This eliminates mirrors, beam splitters, and mechanical adjustment components while maintaining or improving aiming accuracy.
Solution Approach 2:
The sighting device automatically performs ballistic correction calculations and displays the correct aiming point without requiring manual mechanical adjustment by the shooter. The system self-adjusts based on programmed ballistic data and sensor inputs, eliminating the need for complex user-operated mechanical mechanisms while maintaining high precision.
4Speed
If magnifying optics are combined with the sight, then range extension is improved, but the field of view is reduced and mounting becomes more complex
Solution Approach 1:
The electronic display system provides multiple virtual aiming points that correspond to different distances and trajectories, effectively giving the shooter multiple ranges without requiring physical magnifying optics. The ballistic correction unit calculates and displays appropriate aiming points for various distances, eliminating the need for separate magnification settings or additional optical components.

AI summary
The invention relates to a small, light, and economical sighting apparatus (10) for hand firearms in particular for shooting shells with a highly exaggerated trajectory. The sighting apparatus (10) is based on a reflector sight (50) having a micro-display (16), such that text information and image information can also be displayed in addition to the reticle (21). For shells having a highly exaggerated trajectory, a virtual sighting occurs, which displays the desired position and the actual position of the point of aim of the weapon by means of symbols (22, 23). The symbols are caused to coincide by directing the weapon. The desired point of aim is calculated for the ballistic parameters of the ammunition and the input target distance. In order to calculate the deviation of the point of aim from the desired position, measurements for the gravity of Earth and for the surrounding magnetic field are additionally used. The sighting apparatus (10) can be used for different ammunition. Shooting can be performed both in the lower angle group and in the upper angle group, which enables the possibility of steep-angle fire. The sighting apparatus (10) can also be used with night vision goggles without the focus of the goggles having to be adapted to near objects. Furthermore, an IR laser illuminator (17) supports night combat. The sighting apparatus (10) can also be used together with a magnifying target optical unit (3).
