Engineering Contradiction Analysis
1Measurement precision
If a pressure sensor detecting hydraulic pressure of a bowl cylinder is used to measure load weight, then weight measurement can be achieved, but the configuration becomes complex and cost increases
Solution Approach 1:
The invention extracts the weight measurement function from the complex hydraulic pressure detection system and implements it through a simpler detection device that directly measures the physical quantity of the coupler, eliminating the need for hydraulic pressure sensors and related complex mechanisms
Solution Approach 2:
The invention replaces expensive hydraulic pressure sensors with a simpler, more cost-effective detection device that uses strain gauges or load cells to directly measure the coupler's physical quantity, achieving weight measurement at lower cost
2Measurement precision

3Device complexity
If a detection device is provided at the coupler to measure physical quantity variation, then the configuration becomes simple and cost decreases, but measurement capability must be maintained
Solution Approach 1:
The invention uses the coupler as an intermediary element that transmits the weight information of the transported object to the detection device. By measuring the physical quantity variation of the coupler, the system indirectly but accurately determines the weight without requiring direct measurement devices in the transport container
