Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If wireless communication is used to collect operation information from mining machines, then the collection efficiency is improved, but communication reliability deteriorates due to vast distances and obstacles in the mine
Solution Approach 1:
The system performs preliminary actions by determining whether the mining machine can remain within communication range before initiating information collection. The information collection device checks the machine's position, speed, and travel direction in advance to predict if it will stay within range during the entire communication process, and only initiates collection when the condition is satisfied, preventing communication interruptions before they occur
Solution Approach 2:
The system continuously monitors the mining machine's position and communication status during the information collection process. The position information detecting device provides real-time feedback on the machine's location, and the information collection device uses this feedback to verify whether the machine remains within communication range, allowing for dynamic adjustment or termination of the collection process if the machine exits the range
2Area of stationary object
If multiple repeaters are installed to expand communication range, then the coverage area is improved, but the system complexity and cost increase
Solution Approach 1:
The system extracts the communication range limitation from the overall system design by introducing a determination mechanism that identifies when a mining machine is within the effective communication range of existing repeaters. This allows the system to utilize the current repeater infrastructure efficiently without requiring expansion, as the determination process ensures optimal use of available communication resources
Solution Approach 2:
The system dynamically adjusts its operation based on the mining machine's real-time position and movement characteristics. The information collection device continuously evaluates whether the machine can remain within communication range during the entire information collection process, and only initiates collection when the condition is satisfied, making the system adaptive to changing communication conditions without requiring additional hardware
3Speed
If the mining machine travels at high speed, then the productivity is improved, but the communication stability deteriorates as the machine may exit communication range during data transmission
Solution Approach 1:
The system performs preliminary evaluation of the mining machine's speed, position, and travel direction before initiating information collection. The information collection device calculates whether the machine will remain within communication range during the entire transmission process based on its current speed and trajectory, and only initiates collection when the stability condition is satisfied, preventing communication interruptions caused by high-speed travel
Solution Approach 2:
The system continuously monitors the mining machine's position and speed during the information collection process. The position information detecting device provides real-time feedback on the machine's movement, and the information collection device uses this feedback to verify whether the machine remains within communication range, allowing for dynamic adjustment or termination of the collection process if the machine exits the range due to high speed

AI summary
An information collection device of an information collection system of a mining machine collects operation information from the dump truck. The information collection device transmits a position information request command to request the transmission of position information about the dump truck through a second wireless communication device at a predetermined time. When the dump truck whose response to the position information request command is received by the second wireless communication device can stay in the communication range of an in-vehicle wireless communication device until the communication of the operation information of the dump truck ends, the information collection device collects the operation information of the dump truck whose response is received by the second wireless communication device.
