Weapon Movement Compensation via Sensor Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current optical stabilization systems do not effectively address the movement-related inaccuracies in small arms, as they fail to compensate for the barrel's movement relative to the target, leading to missed shots due to involuntary shooter movements and environmental factors.
Innovation Solution
A method that combines image stabilization with a trigger release mechanism, using sensors to detect weapon movement and generate a release signal when the barrel will intersect the target at the end of its flight time, ensuring accurate firing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If optical stabilization is used to stabilize the image, then image stability is improved, but the barrel continues to move relative to the stabilized image due to unsteadiness in the position
Solution Approach 1:
The system uses sensors to continuously detect the position and movement of the barrel, feeding this information back to a computer that calculates the optimal moment to release the trigger. This closed-loop feedback ensures that the barrel's actual position is accounted for in real-time, resolving the contradiction between image stability and barrel alignment precision.
Solution Approach 2:
The patent replaces mechanical alignment methods with an electronic sensor-based system. Instead of relying on mechanical stability or manual alignment, the system uses sensors to detect barrel position and electronically calculates the optimal firing moment, achieving precision without mechanical stability.
2Ease of operation
If the barrel is allowed to move freely during firing, then the shooter can maintain a relaxed posture, but the bullet will miss the target due to barrel movement during flight
Solution Approach 1:
The system performs preliminary detection of barrel position and movement characteristics before the actual firing occurs. By analyzing the barrel's motion patterns in advance and calculating the optimal release moment, the system allows the shooter to maintain a relaxed posture while ensuring the bullet will hit the target accurately.
Solution Approach 2:
The sensor system continuously monitors barrel position and provides feedback to the control system, which calculates the optimal moment to release the trigger. This feedback mechanism ensures that even though the barrel moves freely during the shot, the timing is precise enough to compensate for the movement and achieve accurate hits.
3Speed
If the trigger is released immediately when the barrel is aligned with the target, then the shot can be fired quickly, but the bullet will miss the target because the barrel imparts movement to the bullet during flight
Solution Approach 1:
The system performs preliminary analysis of barrel position, velocity, and movement patterns before releasing the trigger. By calculating the optimal release moment in advance based on the barrel's current state and predicted movement, the system achieves both quick firing and precise point of impact.
Solution Approach 2:
The sensor system provides continuous feedback on barrel position and movement, allowing the control system to calculate the precise moment to release the trigger. This feedback mechanism enables the system to fire quickly while maintaining precision by timing the release based on real-time barrel characteristics.
4Manufacturing precision
If a sensor system is added to detect barrel movement and control trigger release, then shooting accuracy is improved, but the device complexity increases
Solution Approach 1:
The sensor system serves multiple functions: it detects barrel position, measures movement velocity, and provides data for optimal trigger release calculation. By making the sensor system multi-functional, the patent reduces the need for separate components and minimizes overall system complexity while achieving improved shooting accuracy.
Solution Approach 2:
The patent replaces complex mechanical alignment and timing mechanisms with a sensor-based electronic system. This substitution simplifies the overall device architecture by using electronic sensing and calculation rather than complex mechanical linkages, reducing device complexity while improving accuracy.
