Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mining sites, dump trucks often collide with objects, leading to damage and reduced productivity, necessitating a system to prevent or mitigate such collisions by monitoring the state of potential collisions between vehicles and objects.
Innovation Solution
A dump truck equipped with an object detection device, collision determination unit, process system, control unit, and output unit that detects objects in front, determines collision possibility, and outputs signals to reduce damage, along with data acquisition and communication for process history recording.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the transporter vehicle operates continuously in the mining site, then productivity is maintained, but the risk of collision with objects increases
Solution Approach 1:
The object detection device performs preliminary detection of objects in the travel path before the collision actually occurs. The collision determination unit then preliminarily assesses the collision risk based on detection results, allowing the vehicle to take preventive actions before the harmful collision event happens, thus maintaining both productivity and reliability
Solution Approach 2:
The system establishes a feedback loop where detection results are continuously fed back to the collision determination unit, which updates the collision risk assessment. This feedback mechanism allows real-time adjustment of operations based on current conditions, enabling continuous productivity while dynamically managing collision risk
2Reliability
If collision prevention measures are implemented, then collision risk is reduced, but system complexity increases
Solution Approach 1:
The control device serves multiple functions: it receives detection results from the object detection device, determines collision risk, and outputs control signals for damage reduction. By making the control device multi-functional, the patent avoids adding separate dedicated components for each function, thus reducing overall system complexity while maintaining collision prevention capability
Solution Approach 2:
The patent combines the object detection device, collision determination unit, and damage reduction control system into an integrated collision prevention system. By merging these functions into a coordinated system rather than separate independent systems, the overall complexity is reduced while achieving reliable collision prevention
3Object-affected harmful factors
If damage reduction processes are activated, then collision damage is minimized, but operational time is lost
Solution Approach 1:
The damage reduction process is activated preliminarily, before the actual collision occurs. By detecting objects and determining collision risk in advance, the system can prepare and execute damage reduction measures during the detection and assessment phase, minimizing actual collision damage while reducing operational interruption time
Solution Approach 2:
When a collision risk is detected, the system rapidly executes the damage reduction process and quickly transitions back to normal operations. By rushing through the damage reduction activation and completion, the system minimizes the time lost while still achieving the protective effect

AI summary
Provided is a transporter vehicle including: a vehicle; an object detection device that detects an object at a front side of the vehicle; a collision determination unit that determines a possibility of a collision with the object based on a detection result of the object detection device; a process system that performs a process for reducing damage caused by the collision; a control unit that outputs a signal for reducing the damage caused by the collision to the process system based on a determination result of the collision determination unit; a time point data acquisition unit that acquires time point data in which the signal is output from the control unit; and an output unit that outputs process history data indicating at least a state of the process system. The output unit outputs the time point data and the process history data in association with each other.
