Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Remote weapon systems experience decreased shooting accuracy due to vibrations, and existing solutions complicate the control system structure and increase costs with closed-loop feedback systems.
Innovation Solution
A remote weapon system employing an open-loop control method with a controller that analyzes shaking patterns to determine firing times and corrects the firing arm's position using a motor driver, allowing for improved accuracy without redesigning the system when intrinsic properties change.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a closed-loop control system is used to detect and correct barrel vibrations, then shooting accuracy is improved, but the control system structure becomes complicated and costs increase
Solution Approach 1:
The patent extracts only the essential information needed for control - the shaking pattern of the firing arm - and uses this extracted pattern to determine firing timing, eliminating the need for complex continuous feedback control systems while maintaining shooting accuracy
Solution Approach 2:
The system performs preliminary detection of the shaking pattern before firing occurs, and uses this pre-acquired information to determine the optimal firing timing, thereby avoiding the need for complex real-time feedback control during the firing process
2Measurement precision
If the structure of the remote weapon is reinforced by increasing weight or installing connection members to reduce vibrations, then shooting accuracy is improved, but the device complexity and cost increase
Solution Approach 1:
The patent replaces mechanical reinforcement methods (increasing weight, adding connection members) with a control method that uses detected shaking patterns to determine optimal firing timing, thereby improving accuracy without complicating the weapon's mechanical structure
Solution Approach 2:
The system changes the control parameter from mechanical structural properties to temporal firing parameters, using the detected shaking pattern to identify the optimal moment for firing rather than relying on mechanical rigidity modifications
3Measurement precision
If intrinsic mechanical properties such as shape, material, or rigidity are changed to reduce vibrations, then shooting accuracy is improved, but adaptability decreases as design conditions must be changed accordingly
Solution Approach 1:
The patent introduces a dynamic detection and adaptation mechanism that identifies the shaking pattern for each specific weapon configuration, allowing the system to adapt to different intrinsic mechanical properties through software-based pattern recognition rather than requiring hardware redesign
Solution Approach 2:
The system changes from fixed mechanical design parameters to variable operational parameters by detecting and adapting to the specific shaking pattern of each weapon configuration, thereby maintaining shooting accuracy across different design conditions without requiring structural modifications
