Optimization design for orchard subsurface irrigation equipment based on TRIZ theory

The orchard environment is complex, and the arrangement of fruit trees is irregular, making the traditional drip irrigation pipe laying method difficult and energy-consuming, and it cannot meet the different laying requirements of various fruit trees. This paper proposes an optimized design method for an orchard drip irrigation pipe laying machine based on TRIZ theory. Through patent analysis, the stage of the S-curve where the pipe laying machine is located is clarified. The method of evolving towards the micro-level and the TRIZ contradiction matrix are used to resolve related technical conflicts, and ultimately, the optimized design of the drip irrigation pipe trenching and laying device is completed. Discrete element simulation analysis has verified that the designed trenching device has strong soil-breaking ability and low power consumption, demonstrating the feasibility of this method.
