Dump Body Payload Weight Distribution Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Machines with dump bodies, such as mining trucks, face instability due to improper seating and location of payloads, which can lead to operational issues during payload transfer.
Innovation Solution
A system comprising multiple first and second sensors and a controller that detects the distribution of payload weight within the dump body by measuring components of weight exerted through the dump body and its pivotable structure, providing a notification on the status of payload distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple sensors are installed to detect payload distribution, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The detection system is segmented into multiple independent sensor units distributed at different locations (first sensors between dump body and frame, second sensors within pivot pins). Each sensor independently measures local weight components, and the controller integrates these segmented measurements to achieve comprehensive payload distribution detection with high precision while maintaining modular system complexity.
2Reliability
If real-time payload distribution monitoring is implemented, then operational safety is improved, but energy consumption increases
Solution Approach 1:
The system performs payload distribution detection at periodic intervals or at key operational moments (during payload receipt and transfer) rather than continuous monitoring. The controller activates sensors and processes measurements at these discrete periods, providing timely safety monitoring while minimizing energy consumption by keeping sensors dormant between measurement cycles.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system ensures stable operation by accurately determining payload distribution, allowing for timely adjustments to prevent instability and enhance safety during payload transfer.
Implementation Method 1
Each first sensor is configured to detect a component of the weight of the payload exerted through the dump body when the dump body is seated relative to the frame. The second sensors are configured to detect a component of the weight of the payload exerted through the dump body.

AI summary
A system for detecting distribution of a weight of a payload in a dump body of a vehicle includes first sensors, second sensors, and a controller. The dump body is pivotable about pins to be selectively seated and titled to a frame of the vehicle. The first sensors are arranged between the dump body and the frame, and detect components of the weight of the payload exerted through the dump body when the dump body is seated relative to the frame. The second sensors are arranged correspondingly within the pins, and detect components of the weight of the payload exerted through the dump body. The controller determines a status of payload distribution in the dump body based on the component of the weight of the payload detected by the first sensors and second sensors, and generate a notification to indicate the status of payload distribution.
