Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current shell feed devices for artillery guns face challenges in adapting to changing elevation and bearing angles, requiring skilled operators and limiting firing rates due to manual operation, which increases operator exposure and reduces efficiency.
Innovation Solution
A shell feed device with a movable pillar and tilting arm mechanism, secured to the artillery piece, allows for adaptation to different angles through circular slides and racks, enabling automated shell handling and positioning, reducing the need for skilled operators and enhancing safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual operation by skilled operators is used, then shell positioning accuracy is maintained, but firing rate is reduced and operator exposure to danger increases
Solution Approach 1:
The system uses sensors to detect shell characteristics and automatically adjusts positioning parameters without human intervention. The control unit processes sensor data and autonomously controls the positioning mechanism, enabling the system to serve itself and eliminating the need for skilled operators to manually position shells.
Solution Approach 2:
The patent replaces manual mechanical positioning by operators with an automated control system that uses sensors, processors, and automated positioning mechanisms. This substitution of mechanical human operation with an automated control system maintains positioning accuracy while dramatically increasing firing rate and reducing operator exposure to danger.
2Productivity
If automated loading is implemented, then operator safety is improved and firing rate increases, but adaptability to changing angles is reduced
Solution Approach 1:
The system incorporates sensors that dynamically detect the current elevation and bearing angles of the artillery piece. The control unit processes this real-time data and automatically adjusts the positioning mechanism to adapt to changing angles, enabling the automated system to maintain adaptability while increasing firing rate.
Solution Approach 2:
The patent implements a feedback mechanism where sensors continuously monitor the artillery piece's angle changes and feed this information back to the control unit. The control unit then adjusts the shell positioning accordingly, ensuring the automated system adapts to varying angles just as manually operated systems would.
3Ease of operation
If complex crane control systems are used, then shell handling capability is improved, but device complexity and space requirements increase
Solution Approach 1:
The patent extracts the complex control functions from a separate crane control station and integrates them directly into the shell positioning system. By taking out the control functions and embedding them in the positioning mechanism itself, the system maintains excellent shell handling capability while reducing overall device complexity and eliminating the need for a separate control station.
