Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gun sighting systems fail to accurately detect and indicate scope cant, leading to significant inaccuracies in projectile trajectory due to imperceptible firearm tilt, especially in adverse conditions, and current solutions are prone to errors from environmental exposure and recoil forces.
Innovation Solution
A direct, see-through optical system with an electronic inclinometer and indicators, such as LEDs, integrated into the scope to detect and indicate cant direction and amount, providing visual, haptic, or aural feedback without diverting the shooter's attention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional mechanical cant indicators are used, then the system structure is simple, but the measurement precision is low and reliability is poor due to environmental exposure and recoil forces
Solution Approach 1:
The patent replaces mechanical cant indication systems with electronic sensors (accelerometers, gyroscopes) and digital processing. The electronic system detects cant angle through electrical signals rather than mechanical components, eliminating the problems of mechanical wear and environmental sensitivity while providing higher measurement precision through digital readouts.
Solution Approach 2:
The patent changes the measurement parameter from mechanical position to electrical signal parameters. By using accelerometers and gyroscopes, the system measures cant angle through electrical parameters (voltage, frequency) that can be processed digitally, providing more precise and reliable measurements compared to mechanical indicators.
2Reliability
If mechanical cant indicators are used, then the device complexity is low, but the reliability is poor under adverse conditions
Solution Approach 1:
The patent replaces mechanical cant indication systems with electronic sensors (accelerometers, gyroscopes) and digital processing. The electronic system detects cant angle through electrical signals rather than mechanical components, eliminating the problems of mechanical wear and environmental sensitivity while providing higher measurement precision through digital readouts.
Solution Approach 2:
The patent changes the measurement parameter from mechanical position to electrical signal parameters. By using accelerometers and gyroscopes, the system measures cant angle through electrical parameters (voltage, frequency) that can be processed digitally, providing more precise and reliable measurements compared to mechanical indicators.
3Measurement precision
If electronic inclinometer and indicators are integrated into the scope, then the measurement precision and reliability are improved, but the device complexity increases
Solution Approach 1:
The patent merges the electronic inclinometer, indicators, and scope into a single integrated system. The electronic components are incorporated within the scope housing, sharing power sources and mounting structures, which reduces overall system complexity despite the addition of sophisticated measurement capabilities.
Solution Approach 2:
The scope serves multiple functions: optical magnification, reticle display, and electronic cant indication. By making the scope multi-functional, the patent eliminates the need for separate mechanical cant indicators, thereby integrating measurement precision improvements without proportionally increasing system complexity.
4Loss of information
If electronic indicators are used to indicate cant direction and amount, then the loss of information is reduced, but the use of energy increases
Solution Approach 1:
The patent employs periodic or pulsed illumination of the electronic indicators rather than continuous operation. The indicators are activated only when cant exceeds a threshold or at specific intervals, which significantly reduces power consumption while maintaining adequate information delivery to the shooter.
Solution Approach 2:
The patent uses different colors or light intensities to indicate different cant conditions (direction and magnitude). This allows rich information transmission through a single indicator system, reducing the need for multiple indicators and thereby limiting power consumption while minimizing information loss.

AI summary
An electronic indicator on a see-through optical scope indicates whether an optical system is canted. The visual indicator may include one or more LEDs coupled to a microprocessor that is also coupled to a solid-state electronic inclinometer incorporated into the internal structure of the optical system. The microprocessor is configured to selectively illuminate the visual indicator based on the output of the inclinometer, thereby indicating how the reticle is canted, if at all.
