Sensor-Adaptive Tipper Control for Automated Swap Body Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing load transport vehicles require high operator coordination and precision to manage the handling of interchangeable containers, leading to risks of damage to the vehicle, containers, and surrounding objects, especially in confined or obstacle-laden environments, due to the lack of automation in controlling the handling device's movement.
Innovation Solution
Integration of a sensor unit that provides real-time data to the control unit to adapt and adjust the predetermined sequence program, ensuring precise control of the handling device's movement by monitoring hydraulic cylinder positions and environmental factors, such as inclination and object presence, allowing for autonomous operation and collision avoidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual operation of the handling device is used, then the operator can monitor and adjust the operation in real-time, but the risk of operator error increases and damage to the vehicle, swap body, or surrounding objects may occur
Solution Approach 1:
The handling device performs self-monitoring and self-adjustment through integrated sensors (position sensors, inclination sensors, obstacle detection sensors) that automatically detect operational parameters and trigger control actions without operator intervention, enabling the system to service itself during operation
Solution Approach 2:
The control unit continuously receives feedback from multiple sensors monitoring hydraulic cylinder positions, vehicle inclination, and surrounding obstacles, automatically adjusting the handling device operation based on this real-time data to prevent collisions and ensure safe operation
2Reliability
If automated control of the handling device is implemented, then operator error is reduced and operation safety is improved, but the device complexity increases due to additional sensors and control systems
Solution Approach 1:
The control unit serves multiple functions: it controls the hydraulic cylinders for handling device operation, processes data from various sensors (position, inclination, obstacle detection), adapts the sequence program dynamically, and coordinates vehicle movement - consolidating these diverse functions into a single multi-functional control system rather than separate systems for each function
Solution Approach 2:
The patent combines the sequence program adaptation logic, sensor data processing, hydraulic control, and vehicle coordination functions into an integrated control unit that manages all aspects of the handling operation through a unified control architecture
3Extent of automation
If the handling device follows a predetermined swept path, then the unloading operation can be automated, but the ability to adapt to environmental obstacles is limited
Solution Approach 1:
The sequence program is dynamically adaptable rather than static - the control unit modifies the predetermined sequence in real-time based on sensor feedback about obstacles, vehicle inclination, and positional deviations, allowing the automated system to adjust its behavior dynamically to environmental conditions while maintaining overall automation
Solution Approach 2:
The control unit changes operational parameters (hydraulic cylinder stroke lengths, timing sequences, movement speeds) based on sensor data about the environment, allowing the automated handling device to adapt its swept path and operation parameters to accommodate obstacles or uneven ground while maintaining automated control
