Multi-Directional Truck Steering: Selective Component Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators of multi-directional industrial trucks face difficulty in achieving a target position without corrective movements, as existing steering systems struggle to maintain alignment and precision during horizontal positioning maneuvers.
Innovation Solution
A steering method for multi-directional industrial trucks that selectively controls either the rotatory or translatory movement components automatically, allowing operators to align and position the truck with pinpoint precision by determining the necessary movement components and using distance sensors to measure and correct the actual rotational position relative to the target position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the operator manually controls both rotatory and translatory movements simultaneously, then the industrial truck can reach the target position, but the operator cannot maintain alignment and precision during horizontal positioning maneuvers
Solution Approach 1:
The steering control is segmented into two independent components: rotatory movement control and translatory movement control. The system allows selective automatic control of one component while the operator manually controls the other, dividing the complex steering task into manageable parts that can be executed with higher precision.
Solution Approach 2:
The control system acts as an intermediary between the operator and the industrial truck movements. It provides automatic control assistance for selected movement components, mediating the operator's manual inputs and adding automated precision control to achieve better positioning accuracy.
2Manufacturing precision
If the system controls both rotatory and translatory movements automatically, then positioning precision is improved, but the device complexity increases
Solution Approach 1:
The automatic control system is segmented to handle rotatory and translatory movements separately. This allows the system to provide automatic control for one movement component without requiring full automatic control of all movements, thereby reducing overall system complexity while maintaining positioning precision.
Solution Approach 2:
The system implements partial automatic control, providing automated assistance for selected movement components rather than controlling all movements automatically. This partial action approach achieves sufficient positioning precision without the complexity of complete automation.
3Manufacturing precision
If the operator performs corrective movements to achieve target position, then positioning accuracy is improved, but the time required to reach the target position increases
Solution Approach 1:
The automatic control system performs preliminary alignment actions before the operator needs to make corrective movements. By automatically controlling one movement component to establish proper alignment, the system reduces the need for time-consuming corrective maneuvers while maintaining high positioning accuracy.
Solution Approach 2:
The system continuously monitors the industrial truck's position and movement, providing real-time feedback to the automatic control algorithm. This feedback enables the system to make precise adjustments without requiring multiple corrective cycles, thereby reducing the time to achieve accurate positioning.
