Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to enhance excavation efficiency by transporting a large amount of ore in a single instance while navigating the size limitations imposed by the cross-sectional area of mine tunnels and accommodating ores of various shapes and sizes at a high filling rate.
Innovation Solution
A mined material transport vehicle with a conveyor system and rotatable movable flaps that form a storage space, allowing for efficient conveying and storage of ores, even with varying shapes, by rotating the flaps between two positions to optimize space utilization and prevent spillage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the size of the transport vehicle is increased to transport a large amount of ore at one time, then the excavation efficiency is improved, but the vehicle cannot pass through the tunnel due to size limitations
Solution Approach 1:
The vehicle body is divided into multiple segments including a hopper section, conveyor section, and storage section that can be independently configured. The ore storage capacity is segmented across these sections, allowing the vehicle to maintain a compact overall size while achieving large storage capacity through modular arrangement.
Solution Approach 2:
The vehicle utilizes three-dimensional space optimization by arranging the conveyor belt in a folded configuration and positioning the storage section above and around the conveyor. This vertical and lateral space utilization allows maximum ore storage within the tunnel clearance constraints.
2Quantity of substance
If the vehicle is designed to accommodate ores of various shapes and sizes, then the filling rate is improved, but the vehicle structure becomes more complex
Solution Approach 1:
The vehicle employs a movable discharge gate at the rear of the hopper section that can be dynamically adjusted during operation. This dynamic component allows the vehicle to adapt to different ore types and sizes without requiring multiple fixed structural configurations, maintaining simplicity while achieving high filling rates.
Solution Approach 2:
The conveyor belt speed and discharge gate position are adjustable parameters that can be optimized for different ore characteristics. By changing these operational parameters rather than the physical structure, the vehicle accommodates various ore shapes and sizes while maintaining a simple overall design.
