Vehicle Turret Controller Mode Switching for Safe Manual Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manual operation of vehicle turrets can pose a risk to operators due to high-speed spinning cranks during controlled turret rotation, as the crank attached to the motor spins along with the turret, potentially causing injury.
Innovation Solution
A controller system that automatically determines the operational mode and disables controlled operation when a manual mode is initiated, preventing the motor from spinning and allowing safe attachment of a hand-powered crank for manual rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If controlled operation mode is used to rotate the turret automatically, then turret rotation speed and productivity are improved, but the risk of injury to the operator from high-speed spinning crank increases
Solution Approach 1:
The controller disables the controlled operation mode when detecting that manual operation has been initiated, preventing the motor from spinning at high speed while the crank is attached. This preliminary preventive action eliminates the harmful effect before it can occur by ensuring the motor remains stationary or moves slowly during manual crank operation.
Solution Approach 2:
The controller continuously monitors the operational state of the turret and detects when manual operation is initiated. Based on this feedback, the controller automatically disables controlled operation mode, creating a closed-loop safety mechanism that responds to operational conditions in real-time to prevent operator injury.
2Object-affected harmful factors
If manual operation mode is used with hand-powered crank, then operator control and safety are improved, but turret rotation speed and productivity decrease
Solution Approach 1:
The system dynamically switches between controlled operation mode and manual operation mode based on the detected operational state. When manual operation is initiated, the controller disables controlled mode, allowing the operator to choose the appropriate mode for the current task, balancing safety and productivity needs.
Solution Approach 2:
The controller changes the operational parameters of the motor by disabling controlled operation when manual mode is detected. This parameter change ensures the motor does not spin at high speeds during manual crank operation, prioritizing operator safety while still allowing turret rotation through manual effort.
3Adaptability or versatility
If the crank is attached to the motor during controlled operation, then manual operation capability is preserved, but the crank spins at high velocity creating safety hazards
Solution Approach 1:
The controller detects when manual operation is initiated (indicating crank attachment) and preemptively disables controlled operation mode, preventing the motor from spinning at high velocity. This eliminates the hazard of high-speed crank rotation while preserving the ability to operate the crank manually when needed.
Data Source
AI summary
An apparatus for controlling rotational movement of a turret of a vehicle is provided. The apparatus includes a controller that generates a control signal for controlled operation of the turret in a controlled mode of operation. In response to a determination that a manual mode of operation has been initiated, the controller disables controlled operation of the turret of the vehicle.
