Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sight devices for firearms are prone to malfunction due to lens deviation or breakage, and the etched aiming lines and points on the reticle obstruct the user's view, making aiming difficult and inconvenient, especially when considering wind-speed parameters.
Innovation Solution
A trajectory prediction system comprising an objective lens, image sensor, processor, and display, which calculates and displays the trajectory and predictive points of impact, eliminating the need for complex lens groups and providing clear aiming symbols on a screen, including an optical module, distance-measuring module, and anemometer for accurate wind-speed adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex upright group with multiple lenses is used in the sight device, then the optical performance is improved, but the reliability deteriorates due to lens deviation or breakage
Solution Approach 1:
The patent removes the complex upright group (multiple lenses) from the optical path and replaces it with a single reticle and direct imaging path. This extraction of unnecessary components eliminates the reliability issues associated with multiple lenses while maintaining the essential function of the sight device.
Solution Approach 2:
Instead of using multiple lenses to achieve the desired optical effect, the patent inverts the approach by using a single reticle with aiming markings and allowing direct light transmission. This inversion simplifies the structure while achieving the same functional outcome.
2Ease of operation
If aiming lines and points are etched on the glass reticle, then the aiming function is improved, but the sight obstruction increases making observation harder
Solution Approach 1:
The patent applies local quality by making the reticle translucent rather than opaque, allowing light to pass through while maintaining aiming markings. This localized change in material property resolves the contradiction between having visible aiming lines and maintaining clear observation.
Solution Approach 2:
The patent utilizes color or contrast changes in the reticle markings to ensure they are visible against the translucent background. The aiming lines and points are designed with specific optical properties that make them stand out while allowing the overall reticle to remain transparent for clear observation.

AI summary
A trajectory prediction system for predicting a point of impact of an object shot from a ballistic device is provided. The trajectory prediction system includes an objective lens, an eyepiece lens optically coupled with the objective lens, an image sensor, a processor, and a display electrically connected to the processor and the image sensor. The image sensor, the processor, and the display are disposed between the objective lens and the eyepiece lens. When an external light reaches the image sensor through the objective lens, the image sensor transmits a first signal to the display, and the display shows an image according to the first signal. The processor calculates the trajectory of the object and transmits a second signal to the display, and the display simultaneously shows the image and at least one predictive point of impact according to the first and second signals.
