Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If short-range wireless communication is used for power receiving-type information transmission, then power can be supplied wirelessly to devices in long bodies, but stable information acquisition and transmission cannot be achieved
Solution Approach 1:
The system divides the information transmission task into two separate communication channels: one for power transfer and another for data transmission. This segmentation allows each channel to be optimized independently, ensuring that power supply and information transmission do not interfere with each other, thereby achieving stable information acquisition while maintaining wireless power supply capability
Solution Approach 2:
The patent introduces a moving body (such as a vehicle or inspection device) as an intermediary that carries both power transmission and information reception functions. This intermediary moves along the track and serves as a mobile base station, enabling both wireless power transfer and stable data collection from fixed devices attached to long bodies like pipelines or railways
2Measurement precision
If information acquisition devices are installed in long bodies such as pipelines or railways, then physical changes can be monitored, but regular and stable information transmission is difficult due to communication range limitations
Solution Approach 1:
The system transitions from a static communication architecture to a dynamic one where a moving body travels along the track to establish communication with fixed monitoring devices. This dynamic approach allows the moving body to periodically pass by each monitoring point, enabling regular information transmission without requiring continuous wide-area communication coverage
Solution Approach 2:
The moving body is equipped with both power transmission and information reception capabilities in advance. As it approaches each monitoring device, it first establishes power connection and then proceeds to collect information, ensuring that devices have sufficient power reserved for accurate measurement and timely data transmission before the moving body passes
